2003 Audi A4 1.8t won't start!!

Asked by Oct 15, 2014 at 09:44 PM about the 2003 Audi A4 1.8T

Question type: Maintenance & Repair

Did a trade for a 2003 Audi A4 1.8 t on Sunday. 30 minutes after getting the car, check engine light came on. Took it to 2 different auto parts store for the free hook up to check code. Neither could pull it. Took it to a mechanic that specializes in these cars, couldn't pull it either. He said this is usually due to something faulty in the computer, which can be cause by malfunction of the radio (which makes sense in our case because our radio is very staticky, even the CD is static). Went for a job interview an hour away from home, come out and car doesn't start. Had someone that was able to jump the car for me yet still nothing - did a check on our battery (by having the plugs on my battery and seeing if there was a spark on the other end) - there was, which means our battery is FINE. What else could be the issue? Could it be the potential computer issue? Alternator? Starter? Anyone have this before and it be an easy fix? I'm 21.5 weeks pregnant, have appts and interviews and NO car at all, and a 3.5 year old daughter. Please help!!!

If they can,t pull code,s ,it probably is computer,and some time,s on audi,s the key will not be reconized,by the computer,that is why the car won,t start.Sound,s like you may need a new ecm/computer,or have a dealer try to reflash the one that is in there. Good luck with it,

But we haven't had any issues, and my fiance drove the car about an hour before I left for my interview. We are an hour away from the car, and limited on funds - is it expensive you think to diagnose?! Or an ecm/computer?

Computer,s have a mind of there on,they work with no problem,s,,then loose there mind,ecm for your car is expensive,but try and have it reflashed if possible,want be as expensive,if it is not to far gone,you can try this temporarily,remove the key from car,remove positive cable for a few minute,s,then replace battery cable,insert key,this should reset the ecm,where it will crank,but this is only a brief fix for this,,

your description of the battery chek is a bit hazy. it should be load tested. maybe autozone. it must be fully charged for this test but it is the best way to test a battery

I understand however without getting the car to start at all we cant exactly get it to AutoZone....

do the temporary fix suggested above. Remove your key from ignition then unplug the battery for 15 -30 minutes. This will forcibly reboot your cars ecm but will also put your cars stereo in security mode so make sure you have the codes before doing it. this is also a lesson learned never trade for a car you know nothing about especially if you already have a car that is reliable to start with. The gas audi's tend to be more of a hassle then the tdi's so next time trade for one of those love :) good luck

as long as the battery is charged, it doesn;'t have to be in the car to be load tested.
