Right, sorry has taken while to reply, but got car back few weeks ago. Got told oil pump failed again, they replaced that and started the car but still rattling noises coming from the engine, they stripped the car apart again and they eventually came back said I needed a new engine and pretty much everything linked to the engine I.e. turbo and all.
got it all done after weeks of waiting ALL FOR FREE so I would call that a result and a half! Whilst it was in garage, I got an A5 3l tdi Quattro as a courtesy car which I also had to pay not a penny for....
