New member, engine bust

Alright guys, my 2006 A4 2L TFSI quattro engine (code BWE) has given up on me. So need to replace it, but before I settle for a straight swap I have been looking for info on whether the S3 engine would workor not.

So, does anyone know whether it wouldwork or not. I guess i'd need the FMIC from the s3 as well, would i need the ecu and loom also?

Just looking at my options, what about an S4 engine, is that a possibility?

Any info or other suggestions would be great

Cheers
Steve

Seems like the oil pump has been intermitingly working(possible sticky relief valve), had some issues with the oil pressure light coming on, had it checked out acouple times but oil pump was never picked up on. Don't do major miles on it now so never really been getting a long enough run for the pressure to be building enough for warning light to eventually come on hence alot of damage done to engine.

Alot of scoring to cams and followers etc, obviously new pump needed (so engine out job anyway) also and possibly more damage in bottom end etc. Getting into garage this week to check it out properly but need to weigh up my options, fix what's in or buy reconditioned engine. Neither will be cheap.

Car is on 108,000 miles.

Think i've settled on either having my engine rebuilt or a reconditioned one. Just got a little carried away with myself with wild ideas lol.

Mine has a generic map and was more than happy with it, but having looked around the forum it seems I could get a decent bit more power for relatively small amount of work so will head down that route.
