Ignition coils on the VW and Audi 2.0T TSI engines can have some issues. When the ignition coil fails you are likely to get a check engine light, and possibly even a flashing check engine light (You should not drive with this light FLASHING). The faults for bad ignition coils could be misfires on a single or multiple cylinders with possible fault codes being P0300, P0301(for cylinder 1), P0302(for cylinder 2) , P0303(for cylinder 3), P0304(for cylinder 4). These can be checked by swapping the ignition coils to different cylinders to determine if the misfire moves. Note: You will need access to a scan tool to determine the fault codes before and after testing (any generic scanner will work).

tsi cylinder numbers

Example: Your are experiencing a fault code P0301 this indicates you have a cylinder one misfire. If the light is continuously flashing this means the misfire is constant. If your check engine light is stays lit up and you have this fault code this means your vehicle has registered a cylinder one misfire at some time (possibly multiple misfires). You should take the ignition coil in cylinder 1 and swap it with the ignition coil in cylinder 2.

If the misfire then moves from cyl 1 to cyl 2 its safe to say that the misfire is caused by a bad coil. If the misfire does not move you can then try to swap spark plugs which will also help you rule out another item. Assuming that doesn’t work either you very likely have an issue with carbon build up on this intake valves or a bad fuel injector.

 

coil plug set

Ignition coils on VW and Audi 2.0T TSI cars do not have a maintenance interval. Many people regularly replace their coils or keep spares in case they go which can be a great way to ensure a bad ignition coil doesn’t leave you stranded. When you have one go bad we generally recommend replacing them all to ensure you have good ignition coils in your car. It may not be a bad idea to replace the ignition coils every 40k or 60K (check your manual for your vehicle specs) miles when should be changing your spark plugs.

    Just a heads up, a while back I got this code for a misfire and it would sputter at about 5K rpms in every gear with my APR stage 1 tune. When I went to my stock tune the sputtering went away and I couldn’t replicate the sputter. Dealership cleared the codes (this was before I had a Vag-com) and said it was fine.
    Drove it off the lot and it was fine. Pulled into a parking lot and swapped back to Stage 1, and there it was again. After some searching, I simply replaced the coils and it went away. This is in a 2008 MKV, and happened around 2009-2010 when there wasn’t many reports of it yet so I had to really dig to find the solution.
    Now I change coils and plugs once a year or so just to do it.

    Hi I’m having problems with my ignition coils. I took my 2010 vw cc to dealer and they did a diagnostic and found that I need to replace spark plugs and ignition coils. I also have a problem with my trunk harness. I mistakenly replaced the fogg lights because I was getting fault on my screen, but it’s for sure the trunk harness. My question is I live in the stat of Georgia, can you recommend an honest mechanic? I don’t really trust the dealership. They sold me the cc telling me it had undergone some 10-point check. The car had 65k on it when I bought it.Why didn’t they replace the spark plugs and ignition coils?
    Thank you,
    Hope H.

    Hi Paul. When I was leaving my house this morning the check engine light was flashing…car shook a little…a lot of websites are saying its the coils….is this tutorial for 2010 vw cc 2.0?

    I have a 2010 passatt with a 2.0 tsi. The car a few months back began intermediately indicating the cel. Which was misfire on number 2 coil. I replaced the spark plugs on all cylinders and number 2 coil. The problem appeared to be remedied. It began a few weeks back coming on and going off. I swapped the number 2 coil to number 1 to see if I could isolate the issue. The car now is indicating misfires across the board. The car has a sluggish cold start and sometimes has to be restarted up to 3 times then it will level out and idle fine. The car runs fine after operating temp is achieved. The cel remains on. I have replaced the diverter valve 3 months back. I have checked for intake leaks. What gives?? I would assume that if it was an injector or coil it should be constant not just a cold start issue.. Many thanks in advance for even reading this ramble

    My VW EOS engine was running quite rough and I took it to a shop. It registered fault codes for engine misfire, and they recommended replacing the ignition coils. They wanted $800 to do the job, but my husband bought 4 new ignition coils and 4 new spark clubs and did the work himself for a lot less. The car runs fantastic now. Unfortunately, the EPC and check engine light is still on after 10+ restarts and 200+ miles of driving. We just took it to Advance Auto Parts and had the codes ran again to see if something else was wrong. Engine Misfire on Cylinder #3 is all that is showing.

    Do you know if this is a hard latching code, or should it go away on its own? Do you have any instructions on how to reset the check engine light?

    • Paul Barrett

      You will need to have the fault codes erased by someone with a scan tool.

    I have a mk6 gti 2.0tsi with an APR stage 2 tune, intake, downpipe, ect.
    Certain times when i warm start it BARELY wants to start. Like it cranks up to four times more than normal beforenit turns over.
    Was suggested to buy ngk bkr7eix and this warm start problem would go away.
    Thoughts??

      Replacing plugs and coils would be a good start but Im no sure that its going to solve your issue. This could be fuel pump or module related.

    I have a Audi A4 B7. I have replaced the ignition coils a few times and have only one code left. I have to replace the diverter valve this week and my engine started to skip a bit today. I just replaced the coils a few months ago. I have replaced a few different valves and was wondering if the diverter valve can affect the ignition coils? I don’t know if that makes sense but it’s the only other thing I can think would affect it. Would the diverter valve affect the ignition coils? make them go bad quicker?

    Also I have a slow coolant leak. I had the reservoir replaced a year and a half ago and noticed after long drives ( to work about 18 miles) that if I don’t relieve the pressure in the reservoir by opening the cap it leaks below the coolant reservoir. It’s not the head gasket, there is no fuel in my coolant and there is no white smoke coming from my exhaust. I was thinking it was the coolant flange behind the engine but it’s not leaking from there. I am going to replace the cap and see if that’s the issue. I can’t find any videos or explanation on how the pressure is released from the cap on the coolant reservoir.

    Thanks for reading .

    Hi, I need help. (2012 MK6 VW GTI – AUTOBAHN DSG Edition)
    I was driving a 150 mile trip when my EPC Light came on and check engine light flashed. I parked for a few minutes checked online and saw it might go away, it appeared when I was passing a truck and had floored the pedal.

    Went to a VW Dealer, they said cyclinder 3 coil needed to be replaced. I replaced all 4.
    I got the car back and it was running but I could hear a light tickle sound coming from the engine. Technicians assured me all is ok. As soon as I got on the highway to go my 150mile drive back home I felt the engine misfiring as it did before it got fixed.

    I kept it on cruise control to avoid the misfiring from engine, it drove pretty well with nothing notable. When I pulled of the highway and came to a complete stop I started to feel the engine stutter I remained fully stopped for another 30 seconds and the check engine light lit up solid. I drove approx. 100 meters to a safe spot to park and the EPC light came on with very low engine power.

    I towed the vehicle to another VW dealership and they said the spark plug in cylinder 3 broke and there is a Carbon build-up for unknown reason and Cylinder 3 is only able to receive 20psi of compression. They claim engine needs to be replaced. Estimated cost is $8,400. Car value is $14,500.

    The initial dealer that replaced the coils also did work on the recall items; ECM Software update (I read this controls the engine), Coolant pump, and the airbag spring cover. Could any of those have caused such damage?

    Additionally, how could the first VW dealer give back the car in such bad condition that it now exacerbated the issue jeopardizing my investment in the car and causing such high repair costs?
    It all seems unfair. I called VW America, they will investigate but they say they stand behind their dealership technicians. I find it hard to believe that less than 1day from leaving the dealership my entire engine becomes unrepairable. Any help or advice would be much appreciated. The car has been always maintained at VW service centers and maintained at before due dates.

    Thank You!

      Sorry to hear about your trouble. Im not sure how to answer this as Im not clear what specifically happened. The spark plug generally would not just break. It seems to me there is a lot more to this story that would give me more of an idea as to what is going on.

    HI

    URGENT HELP NEEDED

    I have a 2007 AUDI S3 (8P), the car jerks and shudders around 3000 rpm and is especially noticeable when going uphill , happens more when the engine gets warm.

    can this be a faulty PVC Valve or coils or spark plugs?

    Many thanks

    • Paul Barrett
      |

      It could be any of them. You should have it looked at if youre not sure how to start looking into this.

    Hi Paul
    I have a2010 EOS Komfort that has the 2.0 tsi engine and the dsg transmission with around 60k miles .
    The issue I experience is when stopping at stop lights or signs the idle drops significantly and feels like it is going to stall.
    The old days this would typically indicate it needs a tune up.Do you think new ignition coils and spark plugs might fix this?
    If not what is your suggestion(if any)
    Thank You!

    • Paul Barrett
      |

      There are lots of possible causes for this. Plugs and coils could solve your problems but you might have a vacuum leak or other issue. You will need to look into fault codes and diagnostic to determine whats going on.

    Hi Paul,

    Need your advice on the issue I am facing.

    I have a 2011 MY12 Mk6 GTi with Viezu Stg-1 Tune and DSG Tune. I had few issues earlier last year where my car would jump gears and got that fixed by dealership through an update. Later one of the ignition coils failed one evening and got that changed as well. (Don’t know why dealership didn’t recommend changing all 4). Car was fine for the next few months until I started experiencing vibrations and misfires on cold start where dealership diagnosed to be Fuel Injector related or Carbon Build up. I got all 4 injectors replaced along with carbon clean up and everything was smooth. Also, because of rough idle and loss in boost pressue, PCV & Diverter Valve were changed.

    Suddenly in the last 1 week my car seems to have lost power and its getting fairly jerky when cold. In the morning the change between the gears in fairly noticeable and seems like its not running on 4 cylinders. The car feels sluggish to drive even after its warmed up. It will drive normally between 4,5 &6 gear when warmed up and I can pull as well but not as much as earlier. Even when I am stopping at lights I can feel it jerking or when making turns, the car hesitates to change gears and get on the power. Sometimes when switched to triptronic mode, the gear changes are fine but lack of power is still there.

    Are the ignition coils playing up or its something to do with the Clutch packs/Gearbox.

    Please let me know.

    Thanks in advance.

      Im sorry but you have taken care of a lot of the common problems. You will have to have someone take a look at it. Anything I offer would be a guess at best.

    Hi,
    I have a VW Tiguan 2009 and my Check Engine Light turned on.
    I scanned it with a poor scanner and couldn’t read any code, so I reset it. The light came back a few days later.
    I scanned it with a better scanner and got a Cylinder #2 misfire code. I changed the ignition coil and reset the light.
    Again, the light came back a few days later. Whenever I reset it, it takes a few days to come back.
    I sometimes (rarely) feel the engine shake a bit, a soft shake, but when the light is reset, he shaking stops (it might be me imagining things too 🙂 )
    So, in summary, I have the Cylinder #2 misfire code only every few days and changing the ignition coil seems to not have helped !
    Do you have any idea what might cause this?

    Thank you very much

    Hey Paul thanks for all your replies. I have an issue with my 2012 GTI. Its APR stage 2 tuned and I’m getting misfire codes for all 4 cylinders only after start and idle. I’ve been able to see in real time where misfires are occurring and see how many. I’ve already put in new plugs and coils and the problem didn’t go away. I’m getting the most misfires in cylinder 3 so I’m starting to wonder if its an injector because I only have 27k miles. This problem only started to occur after going stage 2. I had stage 1 for nearly a year with no issue whatsoever. I just read the above link as well. I’m hoping I can get my injectors replaced under factory warranty.

      Could be. You should get with your local dealer on this about the injectors

    I have a 2010 golf gti and I can’t figure what’s wrong. Once it’s up to temp (oil and water) it develops a stutter/misfire at 1400-1600 rpm. It says engine fault visit workshop and the EPC light comes on and goes off.

    We had it plugged into vcds and it came up with

    16725/P0341/000833 – Camshaft position sensor (G40) : implausible signal

    I swapped this sensor out with a new one and cleared the codes and still the same.

    Swapped out the spark plugs and coilpacks see if that cured it but still the same.

    Anything I’ve not tried?

    Thanks

    • Paul Barrett

      That points to either a bad sensor or a possible timing related issue. You will need to dig further.

    Hi Paul,

    I have an 09 VW GTI, I keep having issues with misfires. I was just wondering, I had all of the spark plugs changed a couple months ago, should I have changed the ignition coils at the same time? The ignition coils were all done 2 years ago but as I have read, maybe I should be doing all of them once a year?

    Thanks in advance.

    Lana

      Its generally best to change together to make sure you have known good parts.

    Hi Paul,

    I have a 2010 MK6 Golf Gti with around 45k miles. I had my car serviced approx 1 year ago with my local garage at which time they had my spark plugs replaced.

    Since then I have suffered from faulty coil packs on 5 seperate occasions. Always the same scenario – I pull up to a traffic light or a stop, then I go to pull away and only have 50% power, engine starts misfiring and engine management/EPC slight come on.

    On one occasion I had all four ignition coils replaced, on the other occasions just the faulty ones were replaced. Surely this is a manufacturers fault as i have also seen others with the same issue – Is there any long term solution? As opposed to driving around with spare coil packs.

    Thanks for your help, much appreciated,

    Borna

    Hi Paul. I’m from Peru. I have a 2011 seat Leon 2.0t tsi 211 bhp. I’ve heard it’s the same engine as the golf gti. The other day the car start to work as it was only working 3 cylinder but only for 30 seconds and the check engine appear. Then the car began to work normally. I take the car to the dealer and in the vag appear to be a failure in the ingnition coil #3. They recommend to change the 4 of them but the car appear to be ok right now. This was 2 weeks ago. Y want to buy the ignition coils in shopdap and send them to Florida. It’s urgent to replace them if the car seems ok? How Can I know it fits to my car ? Thanks!

    I have a 2011 VW Tiguan with 79k miles. On Sept 11 2016, Four codes – P0301 Cylinder 1 misfire
    We replaced Ignition coil for Cylinder 1 with an authentic VW part from dealer.
    Restarted engine. Serious shakes. Blinking check engine light.

    Computer read 10 new codes:
    P0300 Random misfire
    P0303 Cylinder 3 misfire
    P0304 Cylinder 4 misfire
    P0300 Random misfire
    P0303 Cylinder 3 misfire
    P0304 Cylinder 4 misfire
    P0300 Random misfire
    P0303 Cylinder 3 misfire
    P0304 Cylinder 4 misfire

    Sept 13 2016 We replaced all cylinders and all 4 spark plugs
    Put in Chevron Techron as a fuel additive.
    Check engine light and code disappeared. Drove 300 miles.

    A few days later, the check engine light reappeared with two P0301 codes. Thoughts?
