I am thinking of replacing my 8 year old ECT on my AXX MK5 Golf GTi. Takes a lot longer to warm up since I got the thermostat housing changed and am hoping this might be a quick fix!
Anyone got a part number for one of these? I just called my local stealership and they want £40 for a ECT, O-Ring and Clip. I have seen other people quote as little as £20 on threads?
-
Rich has just kindly sent me a link which shows part number: 06A919501A
The problem is the link shows a grey sensor, but apparently they come in black, green and blue. Could someone please confirm the colour of our sensors?
-
Forgive me plse but is your GTi a 2006 model?

Purchased brand new July 2005. I think one of the first cars delivered in the UK to be a 2006 model spec, I.e with a roof aerial and changed interior.
-
Dont know if it makes any difference but wont that mean yr engine is a BWA?
-
Put the 06A919501A code in to google...
They come up for about 8-10 quid, 5 min fix... you just need someting to catch the coolant when it pours out the side on to your gear box...
The longest part would be taking your air intake of :happy2:
Hope that helps....

You would think that but VCDS reports Engine: Address 01: Engine Labels: 06F-907-115-AXX.lbl

hmmm, odd, anyway, when your needle does eventually get to 90, does it stay there or sometimes go down a bit, then back up again, and so on??

Usually gets to 90C in about 10 miles (previously when the car was new it would take about 2-3 miles) and sometimes comes down to 88C (i.e. not completely vertical!).
Thinking of ordering one anyway and changing it.
-
just when the same thing happened to mine, i discovered my radiator was leaking, and my smaller fan wasn't working, and between fixing the both, my needle goes to 90 and doesn't move!!In the cold weather we have been having, it can take as much as 20 minutes for it to reach 90!! :confused:
-
I had my radiator changed three months back! I think that's when this problem appeared. Hmm!
-
remember of course it will take longer to warm up in these temperatures, especially if your heater is on above 20 degrees! :surprised:

This is very true but having the car from brand new and driving it through 7 winters I know this warm up time is just not normal.
-
Funny that you should say that because I also had my radiator replaced, bout 6 mths ago, and, ironically a new coolant sensor as well, and ive often thought to myself it never took this long to heat up prior; I just put it down to the colder temperatures outside! Maybe a more efficient radiator keeps the engine from heating up to quickly, 'Ministry of the Bleeding Obvious'! :-P
-
should the coolant temp gauge always stay at 90 degrees c on the mk5 platform the same as mk4 platform cars?
thanks.
-
Yes, once it does reach 90, and the duration seems an issue for some, it should stay there! If it then goes down, or up for that matter, usually a sign of radiator problems!
-
Could it not just be the coolant temperature sensor or thermostat?

It could, but for the sake of £7 its easier and faster to just change the ECT!
-
Just tried changing the sensor. Everything seemed to be going fine but I cannot put the new clip back in!! Seriously struggling with that. Already broken one! Any advice from anyone?
-
push it in from the bottom up, with the bottom of the clip more to the back of the car.
if in doubt, take the sensor back out, see what way it fits the clip, and put it back the way it worked, when of the car ...
if that helps

Tried that. Even replaced the new sensor with the old one just in case! Still the clip does not want to go in between the plastic slot around the ECT sensor. I am really struggling. Already managed to break one clip so just one left. Can't believe siting one plastic clip can be this hard!
I am presuming if I dare start the car without the clip the sensor will come flying out!
-
yes it willl fly out, do not do that
-
did you get a new O ring?
-
It looks like it pushes in more from the right hand side:- here have a look at this pic on tfsi mikes mate...

4 th picture down...
Stick your finger in the hole to feel, make sure there is hair no O ring already in there.
Fit the O ring to the sensor, then pop it in place.
but when you look at mikes picture see the way his electric connector, connects, make sure ur's is sitting and fitting the same...
-
Thanks for all the help guys! Finally figured it out!
Basically I was being super stupid and trying to stuff the clip within the little slot in the black plastic holder. That was clearly never going to work, but somehow in my mind thats how it was before! Anyway when I figured out the clip just slides over the slot and not into it, everything clipped into place within a second (used the old clip as I had already broken the new one lol!).
Started the car, both rad fans went crazy 100%. Used VCDS threw up an error of Engine Coolant Temp Sensor, reset it and all seems well. Will drive it around tomorrow and see if my slow warm up issues have been adressed!
-
Good man :congrats: :congrats: :congrats: :congrats:
It was easy really :happy2:
Glad you got it sorted... how bad was your old sensor, take some pictures and throw them up for us guys to see how bad or not it was?
Sometimes we things need to be changed... wear and tear!
-
No Problem!
Its the original 2005 sensor from when the car was brand new.

Just went out for a 'drive' - fantastic, temp gauge started moving at 2 miles into city driving and within 5 miles was up to 90C. Just like old times!

Great stuff :happy2: Easy fix
Time to enjoy now

Indeed, although sometimes I wonder why I enjoy the GTi more than the M3! :driver:

Hi. Can I ask where you got your temperature sensor. I have an 05 AXX engine, but on the sites I looked at they didn't list AXX as compatible with the part no. quoted on this thread. I think I could do with a new one as my car takes forever to get up to temperature these days!

I asked several sellers on Ebay and went with this one:

Thanks for that. You said you got an error code after fitting. Do think you think it would matter if mine didn't get cleared because I don't have access to VCDS for free?

Well all I can say is when I started it up after installing the new one it gave me the P0118 error. It also ran the radiator fans at 100% for 5 minutes after turn off (engine was cold). But as soon as I cleared it, radiator fans have not been on continously. I would suggest you find someone with VCDS close to you when you do it, because those fans at 100% are quite noisy!
-
Ok then, thanks for the help :happy2:

Just a little update. Been driving a little bit more now and noticed that the temperature came up quickly (normal time period) but only to about 80C. Drove on the motorway from B'ham to London only to find the temperature is mostly sitting at 80C and sometimes going up to 85C. Never at 90C. When I am totally driving the beans off the car with loads of boost does it get to 90, but then soon comes down and settles at 80 again.
So the question is, is this £7 sensor just not calibrated right? Is the radiator the Indy fitted 6 months ago not doing its job correctly? Should I get a VW sensor for £30 and try that?
VCDS is not throwing any errors at all. Is there anything I can log to get to the bottom of this. I want my temp back at 90C please and to stay there!
