Ok after some reading, I think im corretc.

Early model 2e ADY is digifrant.

Late model 2e AGG is hotwire.

Am I correct?

There's no such thing as a '2E AGG' etc; the 2E is a separate engine in its own right. The only thing of importance is that the later engines were immobilised through a Digifant II system. In the Mk3, the 2E ran through until '94 IIRC, '95- was the ADY, and later came the AGG until the end of the model.

SEATs used the 2E in later model cars as they were simply handballed VW's remaining stock - as tends to happen with most things.

Ultimately, the only thing to consider is that AGGs will probably have lower mileage and the later injection system made for a better idle and smoother running. It's relatively easy to bypass the immobiliser if you want to run the system properly with EFI in a Mk1.

Can I ask where you have found to be the best info source for the 2E engine?
I have a 2E Digi 2 in my MK2 and it looks to be factory with the way its set up (even has the immobiliser system, that has been disconnected/switched off though).
It seems to be a really hard engine to find information on.

Ahhhh ok thanks for that info Stu.

Ok the reason I want to know is he AGG is hotwire (MAF) which I beleive is better than digifant.
