OEM VW and Audi Coolant Temperature Sensor 06A919501A

October 14, 2015

The coolant temperature sensor is an important part of your vehicle that keeps your engine running properly.  This particular coolant temp sensor fits most current model VW and Audi models (listed below).  It has multiple jobs and can cause a variety of issues when it fails.  The first fault code listed below “P1281 – Performance Malfunction in Cooling System” more commonly is related to a bad thermostat.  The easiest way to tell if this is your coolant temp sensor or the thermostat is as follows.  When thermostats fail on most VW and Audis the cars tend to run too cold instead of overheating.  The means even after the car has run for some time the vehicle will not reach proper operating temp.  This is because the Tstat is stuck open.  If that is not going on with your vehicle then replacing the coolant temp sensor is likely your best solution, as it is usually a simple to install fairly inexpensive.

 

Potential Symptoms of a Bad Coolant Temp Sensor

  • P1281 – Performance Malfunction in Cooling System
  • P1256 – Engine Coolant Temperature Circuit (G62): Open / Short to B+
  • 00522 – Engine Coolant Temp. Sensor (G62): Break in wiring / short circuit to positive
  • Coolant Gauge Inoperable
  • No Start or Rough Running Condition (Not Common)

    please make a DIY Video for coolant temperature sensor and thermostat if you can.

    thank you.

    Auxiliary water pump is leaking. Why are they so expensive?? Is this a common issue.

    Hi Paul,

    Hope you can advise me regarding an issue that I am having with my temperature guage on my 2007 Golf V Gti.

    The vehicle will get up to normal operating temperature (needle sits in middle of guage), but then sometimes it will come down slightly (approximately 1 stripe) to the left of the middle. As if the engine is suddenly running cooler. And then later on it will go back up to the middle or normal posistion.

    I’ve scanned my vehicle for error codes but nothing comes up.

    Regards,

    Francois

    I have a 2008 VW Eos 2.0L FSI Turbo; have had an intermittent P2181 code without any apparent functional problem in my cooling system and would like to start by putting in a new coolant sensor. The problem is that I don’t know where it is or what I’m looking for! Can you help me locate it? Thanks!

      Sounds like its probably fuel related. You should bring it to someone else if they are unsure how to diagnose it.

    Hi Paul

    I have recently purchased a VW Golf VI 1.4 TSI which was running with a slight miss at low rpm more like a lag. Last night I ran the car for about 150 km thereafter the temp gauge began fluctuating between 90 and 130. Both fans were running and coolant was fine.

    After parking it off overnight I turned the ignition on this morning and the needle immediatly rised to 90 while the engine was off. I tried starting the car. It starts but wont hold idle.

    my audi A4 2012 1.8t went on limp mode,i took it for diagnosis test and they gave me a report that my thermostat is faulty,new one was installed and it showed engine management light on the dash,they said it’s upstream lambda sensor is faulty ,it was replaced.recently when I was driving it picked up it’s heat gauge to above 90degrees and the main front fans kicked on.while driving I noticed the heat gauge going up and down and suddently it fell into limp mode again(must not drive to more than 4000rpm)the red warning light came on and stated that the temp is too high as it was around 100 degrees c by that time ,did stop but on inspecting the car I found it not overheating as it was cold.after about 10min I started it again and the heat gauge was normal again but it was still on limp mode.what can be the problem as the technicians says I need to replace the water pump now?

    Hi Paul,

    I have a VW GTI 7, I live in a hot country 28-32 degrees. I have had a check(red) coolant light on and off for a few weeks. First time I topped up just a bit, was not at the min level, since then I have checked but not toped up as level is good. For the past two days my temp gage has been erratic. Sometime its normal at 90c then some times its at the far left of the gage(i think it starts at 50c) Once I saw at the far left I pulled over, switched off, then started again and it worked fine back up to 90c quite quick. I think something might be sticking intermittently as sometimes 90(middle) and sometimes 50(all the way to the left. The check coolant is not real as the level is ok, something else is causing this warning I think. Maybe the temp sensor or maybe a value getting stuck open so sometimes cooling all the time? Any info would be great, thanks in advance, love your youtube channel.
