I understand I should have my ECU scanned for possible leads. But just a quick question.

Just picked up a 99 A4 quarto from a dealer. The CEL came on yesterday. I am sitting here at work and hear the alarm going off with no cause. Is it possble that there is an electric problem and this would make the CEL come on???

Possible that I have Advance Auto Parts scan my ECU and would the given code indicate that an electrical problem is causing the CEL?

 

alarm woudnt cause a CEL have it scanned

 

Were your windows down with the alarm armed/windows locked? There is a motion sensor inside that is easily set off by the wind. The CEL is not related to that. Get your ecu scanned for that one. There is a button on the bottom of the drivers sidecenter pillar that will disable the motion sensor if you press it. Or, with vag com, you can adjust the sensitivity of the motion sensor so it still works, but isnt set off by the wind. Vag Com is Audi/vw specific diagnostic software for your computer/laptop.

 

yes, my windows are down... thanks for the heads up on that...

i am gonna have the ECU scanned at advance. the CEL is yellow. i am trying to schedule the dealer to fix this early next week. as it is still under lemon law warranty and all...

 

Cool. A CEL isnt goingallow you take advantage ofthe lemon law though. You mean you havea regular waranty right? The lemon law isnt a type of waranty.

 

yea, just a 30 day... with the mileage

 

Good luck.

 

check the code and put it here we will diagnose it

 

yeah we will resolve your problem before the dealer can. Although, if its something that is to be replaced under your waranty, and you dont want to pay for it, they will want to diagnose it anyway. But at least youll have a good idea whats going on before you take it in.

 

awesome. i love this forum. its comforting knowing everyone is here to help.

i hope to stop at advance in between my jobs today, if not tomorrow morning... i will repost that code tomorrow... it looks like my dealer "has to schedule something early next week".

thanks everyone for there help with this.
