Hi guys, I've got a 2001 S3 AMK engine which has been using abit of coolant and the engine light keeps coming on. The faults are a lambda probe 'running lean' fault and throttle connection pressure drop. I have already done away with all the dodgy normal vac and breather pipes, there is no obvious leaks. On further investigation I have found cracks in the exhaust manifold and turbo and white/pink staining all over them (coolant). So what's my options on turbos and manifolds, would ideally like to go as high as possible on standard internals ? Thanks.
