coolant temperature problems

[greesha]

Hello

I have some problems with my coolant temperature readings. Looks like it takes a lot of time to reach 90C. Then after some time it can go below 90 (about 80) and stay there for long, even during journey. Also i have quite bad MPG results. As i have read on this forum it might be temperature sensor or thermostat, am I right? Vagcom shows nothing.

Does anyone know part numbers for AUQ engine?

Thanks in advance

how do you mean vag com shows nothing? change your sensor first, they are quite common to go.

genuine parts only though.

I meant that vag com gives no fault codes

you can check water temp with vag com to see if you are reaching 90 degrees

I first had the dodgy gauge so i replaced the sender.
The temp was still only getting to 75 deg (via a scangauge/DM200 i have) so i had the thermostat replaced.
Holds 90 deg perfectly and my MPG as got better

Thermostat was about £5 from halfords with the seal
(might be more than that for you, i have trade club)
This might help

Thank you very much for help guys. I was really worried abbout my MPG . It actually uses now same amount of fuel as my mates subaru, and he is making fun of me saying that i should have bought impreza instead .

Will that temperature sensor fit AUQ engine? Advert doesnt say anything about engines so i guess the sensor is same in all.

Yeah you need a D shape one.
That looks like the one

Part number matches the one i got

did you not get a new clip with sensor? if so just use your old clip

 

[greesha]

I have only one - broken now.

found part number - 032-121-142

Just done this on mine, what a pain, just make sure you pay the extra couple of quid for a seat part, i got one from a motor factors and they supplied the wrong seal, one day later and a proper part, i got the thing full of coolant again. I should still have my old clip somewhere, if i can find it il send it you if you like, thats if you havnt already got one.

Edit, got the clip here on my desk. PM me as i will only get chance to check my emails quickly tomorrow
