The sole reason the dealership told you "No" is they don't want any liability for the work you're about to attempt (not to mention they'd
do it in a heartbeat if your pockets were deep enough)...Or the yoyo at the dealership was misinformed and thought all 08 Passats with a 4-cylinder engine had timing chains (all BPY code engines use a timing belt
Problem with getting another used BPY is all the $*!t you gotta sort through before having any confidence in the engine. Intake cam, follower, HPFP, fuel pressure sender (designed to cause the main fuel pump to run continuously if it fails... main pump failure + fuel pressure sender failure = dealership "double wallet-emptying" score [mechanical scrabble
]), etc. Far too many "band aids" in the design of this power plant (engineering wise). VW released an engine that really didn't have sufficient beta testing. (80K doesn't quite cut it guys...) :crazy:
Yes, any BPY will work if the original engine was a BPY code as you state.
