Crap MPG is normally a sure fire sign of a knackered temp sensor

Does your temp gauge act funny?

Post by: Hulmie on 22 June 2010, 11:56: poppin and blowing to me sounds like it isnt firing properly, which would suggest either ignition module or coil pack failure.

Try the temp sender first and like rhys mentioned, if you have vagcom try do some logging as the guys on here could soon diagnose it with fault codes.

Post by: linz on 22 June 2010, 14:00: yes will re do her on the vagcom

no def not a coilpack problem i dont think though im guessing this also would show up on a vagcom reader?

an surely if it were a coilpack that would be an easy solution for a mechanic to pick up on,,

it seems to have them stumped atm :undecided:
Title: Re: coolant temp sensor
Post by: Hulmie on 22 June 2010, 14:07: yeh it should show on vagcom if coilpack is down, same with ignition module and temp sender.
Title: Re: coolant temp sensor
Post by: linz on 22 June 2010, 14:49: cool sorry im so not with it today well off to go an shuc her on the vagcom now :)

then see wat tht says an then if nothing suggests it i will disconnect the sensor anyway an see what it does
Title: Re: coolant temp sensor
Post by: Hulmie on 22 June 2010, 15:29: just be careful unpluging the connector from the sensor as i bust my clip when replacing my old temp sender

Post by: mick ov mids on 22 June 2010, 15:37: should show up on vag-com , there £36 with vat as had to buy 1 a few weeks ago , you can also buy these from the audi dealership for the same price altho you can get them for around £15 on ebay but me myself id rather buy direct from the dealership for peice of mind.

good lass.

just make sure you top the coolant back up.

Did you get any codes from scanning it? Is it still misfiring?
