Hi, Only just joined so be gentle!! I have recently test driven a 1996 A4 1.8T Sport. Its not a new car I know but I don't buy new cars & as its only 2 grand, it seems on the money! A brief history is as follows. Bloke buys said car & 18 months ago cam belt snaps! Head rebuilt with new valves etc. Late last year the car just stops!? A mechanic friend removes the head & sees 3 pistons at the top which on a 4 potter is not good! He struggles to find an engine & is quoted 1400ish quid for a rebuild with new crank, con rod, all bottom end shells & has bores honed & completely re-ringed. Owner says "OOps". Turns out he still owes money to Mr Finance. The finance company recover their cash & offer my mate the car as payment for stripping the engine. He says Yes. My mates boss pays for engine rebuild & I see it on the front for £2600. I ask him what he'd take & can have it for 2 grand. I take it for a spin & am being gentle after the major internal surgery but when its warm I give it the gun just to see how they go & under hard acceleration, the turbo comes in & it violently cuts out as if I'd turned the key off during take off! I don't have a lot of experience with turbo'd motors nor does my mates boss as it goes! Everything seems to be piped up correctly & I've checked the boost control valve with the values given on autodata. It too seems fine. I am drawn towards the wastegate actuator rod cos it looks like it has been repaired after being broken! Does this rod need to be a certain length to control boost pressure? I'm guessing it does & either the car is overboosting & shutting off or it thinks its overboosting & is doing the same. Any ideas please without making this an expensive car & suffering main dealer labour rates?? Please help. Am i in the right area or should i walk away now?? Thanks for looking. Jonny.
