2001 vw beetle, after replacing my battery my car would only start inthe afternoon when weather is warm outside, Immobilizer problems, car wouldnt start if it was cold outside. If I heat my key with a blow dryer before putting it in the ignition it will start. Key has to be hot ///

SOURCE: Ignition key code problem

"...or is there a receiver in the ignition that could be faulty?"

Hi, I think you will find that there is a little coil in the steering column near where the key goes in which "reads" the key. Whether that is faulty or not is another matter. The best way forward is to get a list of fault codes from the onboard diagnostic system and take it from there. You could either go to a VW dealer, or if you are technically minded you could buy a £15 interface cable, download some free "VAG diagnostic software" and run it on a portable computer.

Hope this helps.D

SOURCE: car wont start but when it does runs great

dealer only sorry

SOURCE: electronic immobilizer

most likely cause is the gauge cluster, this will have to be tested and service by your local dealership because the dash cluster and keys have to be coded. I have seen the immobilizer loose it's coding for apearantly no reason. therefore have them recode cluster and see if problem goes away, if it doesn't the gauge cluster will have to be replaced.

You would have to measure the pressure to determine if it's pressurized correctly. The compressor won't run if it's low.
What happens when you push the a/c button? Can you hear/feel the compressor kick in? It seems like in most cases it's the compressor itself or the compressor clutch that goes. It's way too common in vw's...
