How to change engine / coolant temperature sensor on VW group engines (VW/Audi/SEAT/Skoda) Golf mk4 generation. Car shown is 1.8t Skoda Octavia vRS, same parts and procedure for similar gen VW group motors. Part number: 059919501A
This is probably the only video on RU-vid that tells you how to put the C-clip back in place properly. I replaced my cooling sensor on my vw passat without knowing how to place a clip and next thing I knew was antifreeze spilling out all over the place and engine overheating. Thank you so much for the video !
Thanks this video helped me change the coolant temperature sensor on my Ibiza FR 1.8T the only thing I removed (if I’m correct was the big breather hose from the air filter box) for more space and I only had the 2 pin connector
Useful info here. Your engine seems to be clean as a whistle, but on those that don't I would suggest to spray brake cleaner on the surrounding sensor area to get rid of debris, dust or grime that could get into the coolant system. On B5.5 Passats and B6 Audis the sensor is close to the firewall, much tighter areas, but it is possible to do it without hose removal. Great video.
One tip: Make sure the engine is cold so you can open the coolant reservoir to release pressure, then close it again and proceed to the sensor removal, this way you avoid excessive coolant loss.
Whay you mean is, "the black top was problematic and resulted in those cars overheating but VW decided to let customers replace them when themselves". I had a golf with this engine. It overheated a lot (overheating seems to be a VW problem). Replaced that thing and that car never had problems
Be happy that one isn't like mine. AWM 1.8T. Stuck in the back against the firewall. 😮💨 The price I pay for more torque having it as a straight 4. Thanks for the vid. Surprised no issues prior 230k I'm total miles. Still running perfectly tho.
I have a 1.6 petrol Mk4 Golf and have no temperature needle movement even when the engine is up to temp,management light on and sometimes rough running and idle,think it's definitely the temp sensor.👍🏻👍🏻
Nice video. Very informative. Thinking of replacing mine, only because my warning light is constantly flashing from when I start the engine to when I stop. The engine is not overheating though and the coolant has no leaks. Could a faulty sensor be the cause?
Thanks for this video. I have 1.6l engine but i think i can find that sensor and replace it. Meaby that sensor is not workking correctly becaus my engine temperature goes to 90'c rly fast. I dont believe that becaus its only +10 outside.
every 120K you should Change The Oil Level Sensor. Coolant Temperature sensor. Lambda Sensor. + “what know one “will tell you The Top Strut Mounts Front & Rear 😀
I'm about to attempt this...my fans run constantly and only stop after removing a fuse.. tried re gassing and replaced control module so hoping this works.. 🤞
Hi, my coolant temp sensor has been having issues where it will start leaking at least once a year! The shops just do the same thing (replace coolant temp sensor, o-ring and clip). That works for about 9-12 months. The plastic coolant flange still should be fine since I had it replaced a few years ago. I was going to try to replace the clip with a metal one and also do a new o-ring. Can you let me know how easy it is to get the plug off? It looks like you pushed up with a flathead to get the plug off the sensor. Is that accurate? I know it's held on by the plastic protruding from the side of the sensor you have in your video. Thanks for any info!
I have a vw jetta5 2lt but I have a problem with fan that's running immediately when I start the car, it doesn't wait for the engine to be hot and its one fan which is the big fan on the right, what might be the problem. thank you
Hi, thank you very much for the instructions, what would I ask where to find the temperature sensor in the Audi A4 B7 engine modification 2.0 tdi 16 V code engine BLB
Hi. Great vids, always helpful! Can i ask if the large fan would stop working if this sensor is faulty? The temp guage is iffy, so i know it needs to be done, but i've just found out that the large fan isn't working either? Any advice, always appreciated! Thanks.
can someone help??? i changed this sensor 2 times.. i tried the green and the grey one but no luck... i always get fault code 16500 - Engine Coolant Temp. Sensor (G62): Implausible Signal,,, only in winter cold weather..my cooling fan starts to spin when i turn the key to ignition at cold morning first starts... In summer there are no problems, fan is not coming on and everything just works fine...
Hello i got problem when cold start engine start then shut down few times then i need to go on gas pedal and start car to start engine.. on vcds coolant temp show temperature and on gague show same..
Scott McKinley thanks for taking the time to comment. Coolant temp is low at end of video because it was filmed during cold start. Before doing this we had a very rough idle but new temp sensor sorted it.
My 2014 Audi A4 “overheats” after 15mins of running vehicle, temp gauge starts to almost go to “H” fluctuates between 3/4 - H , and A/C starts blowing warm air... fans stay on after I shut off car but no smoke or anything . I think it might be a sensor ? Please help
It's most likely thermostat, not the sensor. Thermostat controls the flow of coolant through the engine - thermostat is 'closed' (not letting coolant flow through engine) until the engine reaches optimal operational temperature (cca 90 degrees for diesel cars). Once the temp is reached thermostat opens allowing the coolant to flow through the engine, thus maintaining the temperature. If your cars is overheating that most likely means that your thermostat is faulty (not opening when it is supposed to be).
