ECU question

**Valex** · 06-04-2008 11:38 AM

Hey, i am going to be swapping out my old ECU for a new/used ECU. I talked to a few people but before i buy this ECU someone told me about a immobilizer(wont make the car start or something of this nature?), now i dont want to buy this ECU then have it not work in my car. Is it something VAG-COM can fix? or are my GIAC ecu come with the immobilizer deleted?

B5's in the UK all have immobillisers.

Perhaps the US cars are different.

My cousins 1995 B5 1.6 8V has one in Poland (imported from Austria). Its in the key and a sensor in the steering column detects it. It was a pain sometimes as it wasn't working right so car wasn't starting.
