1.4 TSI 160 low compression in one cylinder

Post by thng »

Hello, i bought a used scirocco back in december and after putting a few thousand miles on it the engine light came on with the car going in limp mode, brought it to vw for diagsnosis and they found it has low compression,~ 90 psi in cylinder 1. they say they have to strip the engine to find out whats wrong with it and it could be it needs a new engine alltogether.
At this point i brought the car home saying i'd think about it, because i simply cannot afford a new engine. What is the other best possible course of action? Should i just buy a second hand engine and have it dropped in by a garage?
Thank you in advance

Sorry to hear your problem, if it were me think I would find a recommended recon engine installer, time and money spent trying to repair your engine that probably needs new pistons ect would probably be much more expensive

i bought it from a private seller and im from italy.
i think im going to have the engine rebuilt from a garage, new pistons and head rebored. pistons that will be put in are most likely going to be of better quality than what vw used back in 2008, so they shouldnt crack and i should have an engine i can trust. i dont want to sell the car.

the pistons are fine, although the valves in cylinder one are burnt. im also having the timing chain and tensioner updated and they're replacing the piston rings as well. i will be given a quote on monday though he said below 2000 euros

in the end he replaced piston 1 as well because it had a little crack and it ended up being 1900.

I was about to say, i doubt very much this was down to 'burnt exhaust valves' - that's what every mechanic says when they see the valves on a 1.4 tsi, they are not burn't.
Low compression on this engine, if not the result of valve damage from chain issues, is always a cracked piston.
