Basically, the immobiliser lost its settings and it did not allow the engine to start.

Why it happened?
Many reasons mate, and it can happen randomly by playing with DME. Some says that it can happen when you reset the battery / play with the immobiliser. In your case, reseting IBS may have triggered it.

Worst part is that, I have seen a case where one of the dealer suggested the client to change the immobiliser and keys. And you can guess the rest of the story. Car was out of the warranty and poor fellow had to bend over.... and paid the bill in the excess of ....

Well, I'll leave it to you guys to guess the amount of that bill.

Equally, I have heard of another dealer who charged only 1 hour labour charges to reset this.

I'm glad that it helped mistryn and thanks to all of you for the appreciation
