Hi, recently purchased this car and the pipes had blown on it. Ie the pipe from turbo to cooler an cooler to inlet, after disconnecting sensor and changing pipes, she runs fine but after a certain speed or rev a red light comes on and it says "engine system fault" I then turn her off and she is back to normal only until I give her a good drive then light comes on again and limits me to 3k revs n no more!

Has anyone came across this problem?
Also it starts tapping in high revs? Haven't checked out yet as she parked on a hill, will check oil ASAP,

Last service was 4k miles ago!
