What is the difference between the TDI: ASZ and BLT engine ?

Dash changed also ^^

Again that was not on the engine change, my asz is a face lift.

different pistons in the engine too

So Basically

The ASZ is the earlier Euro 3 compliant engine and does not suffer from a stutter caused by the EGR

.....and the BLT is a nice tasty sandwich!

Sorry, someone had to make this comment.

One day I'll write up a chronological series of changes which were made - which were largely all incremental and discrete. Even the late 2004 facelift changes weren't all made at the same time - my car didn't have the revised dashboard. And we've recently learned that the battery change was after the BLT engine was introduced.

if the anti stutter valve is removed on the BLT the engine light cant be mapped out. (as i found out)
