wnen it was extremely cold, I would accidently run the battery down in my 2002 Volkswagon Beetle Deisel. while trying to start the car. I would end up having to put the charger on quick start to get the car started. With no warning, Itried starting the car, and nothing happened. All the lights would come on, but the car would not even crank, no sound from the engine whatsoever. We put a new starter on the car and it cranks now, but will not turn over.

since you disconnected the battery the idle needs to be relearned into the ecm. working from memory here, but iirc in 2002 that still needed to be done with a capable scan tool.

This capable scan tool theme seems to be a standars reply..but not true! Just drive as you normally do, and PCM will do the rest...

If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!

wow that was great generic info for most cars. unfortuantely some vw's need to have the idle value reset into the computer. i'm guessing you don't have the right scan device/software for this.
