Coolant temp. sensor (vr6)

What can you tell me about this??? I read on vortex that if its faulty your car will run very rich all the time.

Anyone clued up on these (vr6)

 

It's the blue one.

 

I know that, it was you that e-mailed me the link. Is it true about the rich running?

 

yes

 

I reckon i'll swap it for a new one then. Cheers Vic

 

When mine was running sluggish i changed this,only a tenner from VW.It wasnt that that was causing it but its worth trying.

 

If its f**ked the ECU can think the engine is -43 degress and run very rich mini backfires off throttle etc and fuel will come out the exhaust, you can clean polish the senor to get a better reading but this assumes the sendor worked in the first place.

Have you got access to a 1551 or vag.com to check the temp ?
