Hello,

I have the immobilizer Key flashing on my VW Golf 5 1.6. Does it mean that the key is faulty or there's a problem with the immobilizer?

Thanks
F

It could be either although it's normally not the key. Get the codes scanned and if possible, monitor the key status through a diagnostic tool to isolate the problem.

Thanks chittychittybangbang,
The scanner shows the following errors:
No communication with the Instrument Cluster,
Immobilizer Key not recognized,
No communication with HAVC contol Unit

Please help. I don't want to have the instrument cluster disassembled without figuring out what exactly wrong.

Thanks

If it says no communication w/cluster, it sounds like a bad connection. How is the battery? Have you tried the immobilizer troubleshooting in the FAQ article?
