Hi! Just signed up as I've been finding the Tdi stuff here interesting and informative. I've got a 106k A5 Skoda Octavia which I believe has a 1.9 Tdi pume duse engine similar to VWs and Audis (except the code's a BXE). Recently I had a full recon engine block professionally fitted with previous parts and since then there's reduced power most noticably at low revs before the turbo kicks in eg when starting off up hills etc. The top speed's reduced as well, so it could be across the board. The fuel consumption display which used to read around 40mpg in town now reads 28 or so, though the actual consumption is about the same (ie it reads wrong). As previous parts were used (injectors etc) would ECU programming be needed? Is there any way to easily check the timing and the injectors without having to pay for costly dismantling? Or any other ideas, as the workshop mechanics say they're stumped! I'd be grateful for any help. Cheers, Bill P
