I have a 2005 55 plate 1.8t cab > when i brought it i had the Rac do there 300 plus point check and they cam back with the engine number BFB etc i've had audi change the cambelt and water pump over the 3 years i've had the car also 3 other gargaes have worked on it fixing one thing or another had a a broken hose replace rocker cover replaced(turned out they just stuck bits back together and cause a small oil leak!) battey plus starter motor. Now i've taken it to a gargae to fix the oil leak hense why i found out it was stuck last time! and they say when ordering a hose they couldnt find the right one as the engine is from a 1998 audi 1.8t???? with an engine code AEB now either the Rac are wrong and i would have never brought the car or something funny is going on ? At no time has someone swapped the engine out!!?? surely it wouldnt be worth the effort !?
Let me know your thougts i'm going to call the rac and see what they say
