Question about 2000 Volkswagen Jetta TDI
Twice this year my 2000 Jetta TDI would not start because the chip in the ignition key lost its coding to deactivate the immobilizer. Switching keys did not deactivate the immobilizer and I had to get the car towed to a dealer to get all keys re-coded. Are the keys the problem or is there a receiver in the ignition that could be faulty? Re-coding the keys solved the problem but even a brand new re-coded key lost its coding after 3 months so I suspect something else besides the keys.
"...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
