Hi Guys. My engine management warning light has come on. I have to get a new gasket that goes between the manifold and turbo. I have then noticed that there is a pipe that is in the shape of a t-peice that sits at the rear centre of the engine bay that has a hole in it. I am going to get these repaired. I was wondering if this can be causing the management light to come on or am i looking at a bigger problem?
