No problem, thats what im here for.

 

have you seen this "improved darker green square" coolant sensors and if so are they truly better than the blue ones??

 

does the sensor need to have the o-ring installed with it? the old one didn't have one and I can't install the clip to hold the sensor down with the o-ring attached because i can't push it further down into the pipe. if i take it off i can get the clip in.

 

never mind, i saw after several failed attempts that the old sensor's o-ring was still in the pipe. Was I pulled it out everything went back together like a puzzle.

AFter plugging everything back up, i started the engine and it began vibrating at idle for about 30-45 seconds. Then I drove it 3 miles, stopped, turned off engine, waited 2 min, then restarted and it started normally. Went back home and everything seems to be normal. I turned off the engine waited and turned it on again and no problems. No vibration either.

Thanks auditech79

 

Ha glad you got that figured out, when i first did a sensor i left the o-ring in too and i felt like an idiot when my team leader came over and pulled it out for me.

 

Great info auditech79. I have a 2000 a6 2.7t and was wondering if it could be the same part / issue with my car. I am having the same exact problems and it happened out of nowhere. One day my car was running fine and then 2 days later it wouldnt start and would sputter and choke and i would have to hold the gas over 1000 rpm until semi-warm or else it would die out. but once warmed up it can start back up perfectly and runs great.
please respond a.s.a.p. anyone????
