VW Golf 7 outside temperature sensor change

April 18,AM. I've seen over the past while that this is quite a common issue. The coolant temperature should reach 90degrees after a few miles of driving from cold but when it fails it tends to only reach 90deg when idling in traffic or doing city driving.

I currently have this problem which judging by my symptoms I imagine is my main thermostat. Note - I have a manual so don't have the DSG sensor I had alignment booked in with VW on Friday so they said they'd take a look at the main thermostat for free and reported that it was working fine. This happened to be after congested city driving so when I arrived at VW my gauge was at 90deg. I tried to explain this to them but I really got little to no help on the matter. Does anyone know how I can determine this?

Or if it could be anything else? Thank You -Given: 11 -Receive: 55 Posts: I'd like to know how they managed to prove that the thermostat was working fine as it's purely a mechanical device; it's not controlled electrically like other 'valves' on the car. My money would still be on the stat being stuck in the fully open position.

I've got a temp sensor I never used it you want it I had the same issue with my car and it definitely sounds like it's the main thermostat to me. The one that goes on the intake side? Gets to temp fine but drops and then goes back to 90? Got a receipt for new thermostat so don't know whether to take it back to them or not hmmm. Yeah that's the one I've got spare, but to be honest it does sound like mine which was fixed when I had the main thermostat replaced.

Cheers I will let you know if I need one : probably will ring the garage tomorrow where I bought the car Just been for a drive out and it was all good till going steady in 4th then it dropped to 70degrees and slowly went back to 90 haha. Quote from: chris s on November 02,PM. Changed the grey sensor today and everything seems to be the same Also is there only 2 coolant sensors on the gti? Sorry for all the questions!If you are getting odd performance from your HVAC system there is a chance that the outside air temperature sensor is going bad.

Replacing the sensor itself is easy and takes just a few minutes; unfortunately you need to remove the bumper cover to get access to it.

You do not need to lift the car or remove the wheels to take the bumper cover off, but it will give you more room to work if you do. If you want to lift the car please see our article on jacking up and supporting your vehicle for additional help.

A great many of these cars have had the engine trays and front side shields removed over the years and not replaced. If you happen to have a car that still has all the under trays and original hardware here is what you need to do.

There are four T25 Torx screws red arrows on each side holding the tray on, remove them and slide the tray back out of the friction clips yellow arrows on the front air dam. Large Image Extra-Large Image. Once the screws are removed slide the tray red arrow back and down.

To remove the lower wheel liner; begin by loosening the T25 Torx screw just in front of the strut red arrow. The liner is not actually screwed to it so you just need to loosen it enough to allow the liner to slip out.

There are four T25 Torx screws holding the lower liner to the vehicle Three in the front of the wheel well yellow arrows and one on the lower front edge not shown. With the Torx screws removed red arrows and the inner Torx loosed yellow arrow you can slip the liner down and out from the vehicle.

From inside the wheel well looking forward you can see the side marker red arrowfog light yellow arrow and the head light washer nozzle green arrow. Remove the side marker by pressing in the clip on the edge rear edge red arrow and push the assembly out.

With the unit out of the bumper you can see the retaining clip red arrow and the wiring connection yellow arrow. Pull the wiring red arrow straight back and off the plastic unit yellow arrowthis will separate them and expose the bulb. Back inside the wheel well you can see the rear of the fog light. The wiring harness yellow arrow connects to bulb red arrow which sits in the fog light assembly. Turn the bulb base counter clockwise until the cut outs in the fog light assembly line up with the tabs in the bulb base red arrow.

If you want to leave the bulb in the housing simply unplug the wiring connection. Remove the T25 Torx screw that attaches the bumper cover to the fender red arrow, one on each side. On the right side of the vehicle is the windshield washer reservoir. Separate the quick disconnect connection for the head light washers red arrow by pushing in the connection and then pulling straight back.

If there is fluid in the reservoir be prepared to catch it in a container when you disconnect the hose. Remove the four T25 screws holding the bottom of the cover to the lower mount below the radiator red arrows.If you are starting to have trouble with your idle there is a good chance the Intake Air Temperature Sensor is starting to go bad. If you are getting an error code indicating the IAT then it is time to clean or replace the sensor.

The sensor is located on the top of the throttle body at the front center of the engine. It is possible to clean the sensor with MAF cleaner or simply replace it. The sensor is not expensive and many people just swap in a new one rather than buy a can of MAF cleaner and hope it does the trick. If you do not have an aftermarket air induction system that eliminates the engine cover red arrow you will need to remove the cover. Please see our article on engine cover removal for additional assistance.

Large Image Extra-Large Image. Begin by locating the intake air temperature sensor red arrow on the top of the throttle body.

Due to the location of the clip they get very brittle over time. Carefully squeeze in the tap on the rear of the clip red arrow and pulling straight off. Disconnect the wiring harness red arrow from the sensor yellow arrow. Next use a T30 Torx and unscrew the single screw red arrow holding the sensor to the intake manifold and pull the sensor straight out.

You can now attempt to clean the sensor or replace it with a new one. The sensors develop an amber looking coating on them and over time with can harden to a glass like coating. Carefully use the MAF cleaner and some Q-tips to clean both wires. If you break any of the wires you will need to replace the sensor. Installation is the reverse of removal.

I described the issue to a VW technician who suggested it was the temp sensor, I collected the part today and he said it's near the pollen filter.

I've searched the web for around 2 hours now to find out where it goes, I know where the pollen filter is. Posted 12 February - AM.

Does your car have the Climatic semi-automatic air conditioning or the full 2-zone Climatronic climate control? But I don't think the part you mention is that one.

I believe there are other interior temperature sensors. I think VCDS has mentioned a footwell temperature sensor so perhaps that is what that part is. The heater never used to work at all, had a full service done and got VW to check the car but they couldn't find anything wrong apart from confirming the heating not working.

They've guessed that a sensor isn't working properly and ordered a new one so I thought I'd fit it over the weekend. Just cannot find any diagrams showing where! Best part of this is that the heating now works after about 15 mintues but I thought I'd fit the new sensor anyway.

VW don't know how it's started working again but think they may have "knocked something" while investigating. Community Forum Software by IP. Menu Software by ProMenu. Exclusive uk-mkivs stickers now available from Syco Graphix. Order yours today!

Hi guys the other day i removed the front bumper on the golf to fit a radiator and at the same time i fitted a battery, then that was it, but when i got back in the car i noticed the outside temp gauge was not working anymore it was just showing C no numbers, so i assumed i had forget to connect it back up after the removing of the bumper, on checking i found all was in order, so i thought it must be the sensor itself, so i got a used one from breakers yard, fitted that and its still the same??

Or do you think ive damaged the wiring removing the bumper or something, connector looks fine no corrosion etc. Any ideas chaps greatly received.

Posted 24 December - AM. How about disconnecting the battery again, for say 15 mins and re-connecting? I was just curious it was'nt a reset type issue or something like that,could it be an issue if i replaced the battery and reconnected the bettery up whilst the bumper and sensor were off the car, as i removed the radiator and while i was waiting for the new one to be delivered i replaced the battery not something silly like, it was'nt fitted when reconnected so it does'nt know its there or something daft??

Posted 24 December - PM. Shouldn't make any difference, but try disconnecting the battery again first to see if that cures it. I had the same issue on my 1. If you plugged it in after you reconnected the battery for some reason they tend not to work. If you plug it in then reconnect your battery it will. Just take off the battery and reconnect and it should be fine.

I need to relocate mine at the minute as it was showing 10degrees C last night when Im certain it was about Posted 26 December - PM. Weird but its working, as said above took battery lead off and left off for an hour reconnected and working again perfect excellent [B].
