sounds like your crank sensor is toast apr_a4

 

Thanks onepoint8tee, that's one less thing that can possibly go wrong tomorrow... hope nothing does. I'm really not a pessimist, but it seems like a lot of guys having problems with one thing or another soon after chipping.

 

i sure hope not im going to have a local tech look at it this weekend

 

Sounds scary.... Is he vw/audi certified? Most non Audi certified mechanics pee their pants a little when they seean Audi roll up that doesnt need a tire plugged.

 

he is tight on cash he is litterly counting pennies, he will come for sure since he is trying to leave the stealership because he just opened up his own germanrepair shop and has most of his tooks with him all the time

 

I have an 06 A4 Avant 3.2Q 6M. Every once in a while when I crank the car the EPC light and traction control light light comes on and there is no power. I took it to the dealer and he said no codes, and since it only happens every once in a while it'll be hard to track down. He said he "reset" everything and maybe that'll take care of it. Well, 2 days later the same thing happened... started the car at lunch, EPC light, no power. I just turn it off and then restart and everything is fine.

Any ideas?

 

I had the same exact thing happen to me a couple days ago. It was frigid out (about zero degrees) when I came out to my car in the morning. Started it up, EPC and CEL came on and then it goes into limp mode. After I let it idle for quite awhile and warm up, turn it off, restart, all is good. Drove about 15 minutes to work without anymore problems (CEL did stay on steady). Cruised over to autozone at lunch (started fine this time, no limp mode, no EPC, CEL stayed on steady) and had them pull the codes: P2101, Throttle Actuator Control Motor Circuit, Range/Performance. I also performed a Throttle Body Adjustment (TBA) (turn the car on, but don't start it, hold the gas pedal to the floor for 5 seconds, turn the car off, take your foot off the gas, leave the key in the ignition the whole time, wait about 2-3 minutes for a full adjustment) at lunch, not sure if that helped or not. There isn't much history on this on this code in the forums (searched audiforums, audiworld, audizine..) but I did find this on AudiWorld.

Basically, after work that same day, the CEL went out (didn't clear the codes or anything) and it hasn't come back on. I think my issue was directly related to the cold weather I was experiencing. You could try a TBA, or else you might be looking at a new throttle body if you continue to get the errors, not sure though.

 

Keep reporting it to the dealer and make sure a record is made of it. In other words, and unfortunately, take it in every time it happens until its resolved.

Also, read this

 

check 1) engine speed sensor 2) throttle position sensor - turn key to 2nd ( dash lights) press accelerator 10 times and take key out and start car, if it fixes problem then its that if it doesnt 3) if it was raining during this trip you wiring harness could have an exposed wire and it short circuited and freaked your ecu, as much as i've read up on it its usually 1 or 2 and rarely 3
