    Thank you so much for doing these videos, because of them I've replaced my brakes and now the sensor. Your videos are invaluable and help get into working on my own car. Again thank you!

    Very helpful video! Thanks!
    The only thing I’d add is to check the old ring seal comes out with the sensor. Mine didn’t and the new one wouldn’t fit until I realised what had happened.

    Thanks so much BMAC! did this to my golf and it completely transformed my car! idles smoother, much more power and better fuel economy! I guess this sensor was telling the ECU all sorts of incorrect readings! £33.80 from VW well worth it!

    Excellent video. Twice I've had problems with my mk4 1.6 Last year, sometimes it wouldn't start after a journey and the temp gauge was always on zero. AA man diagnosed coolant temp sensor issue and I watched your video on how to replace one. The mistake I made was not getting a genuine part, as exactly one year to the day the sensor went again, this time I was getting a false overheating reading on the temp gauge and 'check coolant service manual' warning. Again AA man said engine wasn't overheating. Got a genuine part this time and working good as new now. I've learned my lesson.

    After replacing the HT leads on the advice of the RAC mechanic (cost about £50) I still had rough running so started a search on the internet where I found your video. After fitting a replacement sensor the misfire has gone and also the heater is working properly again. The only hassle was when I was doing the switch over. I pulled out the faulty sensor but when I tried to quickly insert the new one it wouldn't go straight in. The old O ring was wedged in there and I lost a fair amount of coolant while probing around to remove it before I could put the new one in place. That meant I had to top up the system with water and antifreeze but a minor inconvenience overall. Thanks a lot for your clear explanation and demonstration. It will get me brownie points with my wife when she gets back in the car. It's a 2001 Polo 1.0 by the way.

      Hello BMAC VAGS!
      Great VID... I am about changing it on my Golf at this very moment.
      My question is: This O ring mentioned by John, I cannot see this O ring in your vid.
      What must I do with this separate O ring? .... which came along with the new sensor spare part.
      Appreciate your comment on this issue.
      Thankyou & best regards
      Thomas

    • @robertpreston6084

    Thanks for the vid. Have a Polo 1.2 and just done the swap. Its in a similar location to the Golf in this video and removal/fitting is the same. Tip I would say is when removing the old one and sticking new one the old ring can still be stuck in there so you will have to stick your fingers in to remove as I had with mine. And make sure you wear gloves and car is stone cold.

  • @gerrygreen1

      BMAC VAGS
      I firstly ordered one of the sensors but it wasnt genuine. I fitted it as per your video.
      For a week everything was good. Then day 8 after 10 mins driving the temp gauge would fly up to max, then back to 90, then back to max with the temp warning light flashing...and so on. I checked and coolant level was fine as was oil.
      Lesson learned.
      Just now i have gone and fitted a genuine one (should have listened to you first!! haha)
      All went well (havent driven it yet).
      It leaked a tiny bit once i clipped it, but a wiggle and all seems well.
      From under the car looking up, i can see part of the brass/copped part of the sensor (like it isnt seated properly)... but from above it looks like its in straight.
      Could you confirm that the copper/brass is visible from the side facing the rear of the car from underneath for me????
      It will put my mind at rest haha.
      Thanks again!
      you star

    • @paulypj

  • @fbevc
    @fbevc Před 7 lety +1

    I cleaned the throttle body on my polo 6n and the idle jumped to 2000revs.. Thought it just needs to relearn the idle position, but it turned out to be the coolant sensor! The mechanic that i took it to for vag com TB alingment said to me straight on i need a new TB (which costs 300€), which seemed to work fine to me, so really, if you have any problems with how the engine runs, it pays to check the coolant temp sensor.

    I have changed the coolant temperature sensor in a Passat but when I put on the horseshoe clip to keep it in place it clips in place but doesn't hold the sensor in place securely. It does take some force to pull it out but I can pull it out and the engine light has come on again since I placed it. Do I need to replace the rubber O ring or what am I doing wrong?

  • @lecobra418
    @lecobra418 Před 2 lety

    Thanks for the video my car is running rather smoothly but the temp gauge is showing no value most of the time, I think the sensor is faulty BUT when inspecting it I also noticed the wiring was badly hurt, actually it even broke the minute I touched it, I solder back everything together and protected the wiring correctly, I will change the sensor and hope my issue is the sensor and not the wiring.

      the cooling temp. When its running stationary the temp goes normal to the haf and when I drive in the highway the temp drops... is this an thermostat problem or a coolingsensor? and when i am parking and im turning my steering i hear an cracking noise like an old door that opens slowly... is this the steering joint?

    My mark 4 (1999) Golf indicates a coolant temp at around 60 degrees while cruising in cold weather (about 10 degrees ambient or lower). Noticed this after I replaced the radiator after a minor crash. The new radiator has a higher fin density. Could it be that the new radiator is too efficient?

I cleared the code twice and within 2 days it comes back as pending. Do I have a defective Temp Sensor? I bought an OEM one.

    Hi mate...thanks for sharing that info. One quick question: is it me or is it difficult to find retailers who sell genuine VW parts? I've searched high & low online for a retailer here in Ireland selling the "real McCoy". Loads of new spurious parts from countless brands which are compatable but for the life of me I can't find a genuine VW coolant temperature sensore online! Where to you shop for your VW parts? Do you have a favourite online reailer I might be able to buy from and have shipped over? Many thanks.

So far I have replaced the throttle body, which is now disconnected so its really rough to drive, but at least the thirst has gone down a bit and she's not revving at the lights and upsetting pedestrians!

    Morning BMAC VAGS, I have a query for you. I have a 1998-99 1.6 Golf, my problem is my temperature gauge after a few minutes drive goes up to around 90 but all of a sudden it drops to 0 again. Could this be there thermostat or the temperature sender? My fan in the car does blow hot air or cold when selected so that may rule out there thermostat. Also i get a very slight judder at one and a half thousand revs. My spark plugs are fine so could the sender also cause this problem?? subscribed too :)

    You've really helped me alot with your videos, I never subscribe to people but you deserve one! I found a temp sensor on ebay from VW UK, for 4 £, do you think it's the real deal or what?

      I would say so. If the temp gauge is stuck on zero all the time, or it's going to the red zone falsely (get garage to check the engine isn't actually overheating on this first) giving you a false overheating reading then likely to be the sensor. Get a genuine part to replace it though.
