A6 problem with warm start
Hi, I’ve been having problem with the A6, 2003 model.
It run well when its going and starts up first time when its cold but when the engine is still warm it takes a while. I’ve read a few post and it appears to be a reasonably common fault. Has anyone got it fixed or found out exactly what the fault is? However, strangely enough I took the car into Lincoln, Audi and it appeared that they’d never seen this type of fault before. They have even told me I could need a new pump, which they say will be just under 2 grand!!!! I can only think thats incorrect as the car runs so well once its started. All suggections and advice would be great! :) -- Posted at author's request, using http://www.AutoBoardz.com interface Articles individually verified to usenet standards.

A6 problem with warm start
Try to pull the codes but my guess would be:
- The engine temperature sensor needs to be replaced - $20 and easy to do. - dirty injectors - run a bottle of Techrom injector cleaner in a tank or two. Find another dealer fast or, better yet find an independent with a good reputation with the locals. helendawnw wrote: > Hi, I’ve been having problem with the A6, 2003 model. > > It run well when its going and starts up first time when its cold but > when the engine is still warm it takes a while.

But I had a chat the other day with one of buddy who used to drive a VW Passat(suppose VW and Audi is the same maker), he had the same problem with starting, he said he had to change 2 fuel pumps to fix the problem. He also mentioned that change a pump is easy, its located in the trunk, just lift the floor mat you can c it. but I havent check it yet since I was on a trip just came back to town, will do tomorrow and let you know |

He came out with a fault code P0116, which is Coolant Temp. Sensor out of range. He said it will cost about $135 to change it. I looked on line for the part, the price is about $22 on some of the website. I had thought to change it myself and then realized its too difficult a project for me. Beside even if I can do it myself, I still need to erase the fault code. So I had it changed this morning at the garage, the suprise is, it only cost me $79. May be the service man is too smart to read a customer's mind. Give out high qoute but keep final price low alway makes customer smile and come back. |
