Ok so I changed the oil and filters on the VR today and now it doesn't start, it fires for a second and then dies. The battery's been disconnected for a while which I guess might have helped cause the problem?


Anyway on VAG-COM it shows 17978 - Engine Start Blocked by Immobilizer & 01177 - Engine Control Unit - 65 - 10 Unauthorised - Intermittent 


So the immob has obviously decided I'm not allowed to run the car. From what I've read my options are;


1) Replace the reader coil (Maybe faulty)

2) Have the Immob on the ECU defeated (anyone know how much? United motorsport maybe?)

3) Recode the Key/Immob using VAG-COM (Would need instructions from somewhere)


So any thoughts on what's most likely the issue and best fix? Need to get it sorted ASAP as i'll be racing soon!

Hi Guys, a few months later but, I have the same problem which left me at the side of the road on the way to work! Whilst I am English, I moved to France ten years ago. Three years ago my Dad said "Come to England and pick up the VR6. it's yours!". Today, I found myself in the shit with the same problem that you guys had! I'm having some trouble understanding what you finally did to "turn it off will 100% fix it".

She will start once after a battery disconnect and then BLOCKED! Disconnect the battery and, good to go ONE TIME ONLY!
