Bought my self a 2001 a3 1.8t AUM with a blown turbo for £500. It has all type extras from elec seats to a.c to bose system and thought I'd got my self a bargain! I am a mechanic so it's little project. I took the turbo off and got it rebuilt and made into a hybrid a the same time. Fitted the turbo and Filled up with new 5 30w oil. Took it out and it was going like the wind! Is was said to have been remapped to 212hp before apparently. Then on come 3 beeps and flashing oil can!... from what I know this is lack of oil pressure so limped it home but at the last set of lights it started to sound like a. Diesel or like a slack chain.
I'm going for 1.8t sludge with pick up and oil pump
Now all I can think of is the lack of oil pressure has stopped the tensioner on the chain inside and it's rattling. Getting it towed to my work later on and will investigate but want other peoples input please
