you done a vag com scan?

Ive had an ecu light on for a while, with no decrease in performance/running, well not noticable anyway!
I bought a fault code reader off ebay for around £35, and logged the recurring fault as the coolant temperature sender. I would plug the fault code reader in to clear the code and 24-48hrs later the light would come back up!

I checked on here to find the problem and its down to the temperature sensor and that it needed upgrading to the green sensor. I changed it to the green sensor and cleared the fault and its solved the problem!

If yours is not running any differently it could be down to the same sensor? Supposedly a very common fault on VAG cars. If you dont have vag com, 1 of these fault code readers is worth its weight in gold!

nice one thanks for your help, im not 100% but i think i have the green sensor , but i will check, no i dont have vag com, but i saw in GOLF mag for 50 quid a reader and fault clearer, with no need for a laptop it havs a readout on one end, so i think ill get one of these

Im sure the 225 car comes with the uprated green sensor. The 210 definitely does not. It is worth checking though!

This is who i got mine off and for the sake of £40 its definitely worth having stored in your glovebox incase of an engine warning light

fault reader sounds a good idea if you dont have a lappy, I wander if anyone in your area would be willing to help you with vag com?

all the best with it rick

*fault code reader looks like a handy bit of kit!
