hi i'm hoping somebody can help me i have a 2002 jetta tdi that i bought when i was averaging 20k miles a year on my old car, so i bought a tdi for the mileage and longevity. since then i have had a company vehicle and only put 43k on it in 8.5 years. i replaced the battery about 1yr ago but it goes dead because sometimes i dont use it for weeks at a time. the last time i went to use the car i charged the battery first but when i tried to start it , it would start but stall right away, tried serveral times then i noticed the immobilizer light on the dash. couldnt find any useful info in the manual or repair book, what is the first step to try or how do i reset the code, i do have the plastic tag that came with the car,( both remote keys and valet key respond the same)

thank you in advance for any help

Hi, welcometomyturbodies

I've heard of leaving the key in the ignition in the on position but not started for 20-30mins but other than that this should help.

Well hopefully it'll sort it, there seems to have been a lot of people posting with immobiliser issues lately but at least you have the skc code if needed.

Welcome to the forum. welcometomyturbodies

These immobilizers are a pain in the a**e as I've found out http://www.myturbodiesel.com/forum/f4/passat-immobilizer-4472/ I've nothing against them if they work as they should but if you change the battery it puts the immobilizer providing its the genuine key that matches the system that sould make any difference. You probably have to get a dealer come out to reset it fo £80 each time.

I've read loads of reports saying leave the ignition on for 15 miinutes, 30 minutes, an hour and a half even all night but that doesn't fix anything.

Is the number on the key tag the SKC?

Timing belts and Immobilizers are the most asked questions on here.

Lol still a sore point.

thank you for the invaluable info. after a full charge of the battery, reconnected, and set the parking brake to disable the daytime running lamps i turned the key to on and let sit for about an hour and it started right up.

thank you
