So on a short drive last night after coming down a hill and engine braking I turned into a side road and started to slowly accelerate just as the car was coming on to boost big cloud of smoke again and the check engine light has now come on. I am yet to read the fault code as need to buy a reader.
But two things, I have been thinking about the question was this happening before the oil change and that got me thinking as to what happened at the oil change. A couple of things have sprung to mind, I used liqui moly engine flush prior to oil change, coolent change and the cam belt was changed. Now I can't see the belt causing any of the issue, BUT would the engine flush ruin the turbo seal?
Also 2 weeks ago I made sure the coolant was at max, now it is around 5mm lower in the expansion bottle. Not sure if any has been used or has just settled.
