Audi A3 CEL

[bigcol]

So I get a CEL on my A3 two weeks ago, I noticed that the Temp Gauge was stuck at 0 so I went out and purchased a replacement Coolant Temp sensor. The CEL disappears and everything seems great. A week goes by and the CEL comes back on and the temp gauge stops moving again. Possible that I got a bad coolant temp sensor ?

Any other ideas ?

[soundwave]

its possible, check the wires going to it. maybe you have a loose/broken wire?

Also check the connector for any corrosion or gunk.

[bigcol]

could it possibly be the thermostat ?

[wparsons]

Shouldn't be... even if the thermostat is stuck wide open it'll get some heat in the coolant.

and if it was t-stat it wouldn't have changed when you installed the new CTS.


no cel? you got vag com?

[bigcol]

I don't have a VAG COM unfortunately. I posted in another thread, that I wanted to get the CEL checked and offered some beer in return of a code read.

Let me know if you can hook me up with a vag com read out ?

Hey Guys,

Anyone on here from Mississauga or Oakville area with a VAG-COM ? Looking to get some codes.

Thanks

Was the replacement sensor an original Audi part?

Aftermarket

Try purchasing from the aftermarket.
