Title: Random immobiliser fault code? Solved
Post by: beppe2672 on 10 November 2013, 10:26

Had a bit of a strange fault occur the other day, just thought I'd share it with you guys in case it happens to any of you.

Jumped in my car on Friday to drive home, turned the key, nothing happened, got the jump leads out, still no joy. Got the laptop plugged in with VCDS, 1 fault code, it was coming up with an immobiliser fault. Tried cold booting the car, fault code still coming up. Seen as though the car wasn't even cranking I thought it must be an issue with the immobiliser it's self. So I pulled the dash apart. Immobiliser was good, harness was good transponder ring was good. At this point I was pretty stumped. So I thought sod it, ill check the starter motor just in case, solenoid was knackered, I guess it was creating enough of a voltage drop to make the car throw up an immob fault! Replaced the starter and it was all good! Immob fault proper threw me off!
