    Very smelly diesel engine

    I think I've managed to do a reasonable repair in the swirl flap shaft. The bad news is that the acrid smell still exists. I am of the opinion that this must be exhaust gas escaping before the catalyst gets to work on it, but for the life of me (and the local mechanic, and the MOT man) I can't...

    Noise turning right

    So if you coasted down a nice wide hill and weaved hard left and right you'd get a grinding sound from the front left as you weaved right, but it would quieten as you turn to the left? That would indicate it being the front left wheel bearing failing and grumbling when it's under load. If it...

    Very smelly diesel engine

    Remove the engine cover and look to the left end of the inlet manifold. ( I think you may be able to see it without removing the cover - not at the car at the moment) You will see this. The clip to the left of the the area ringed in yellow is holding the cam-belt cover, Just above the yellow...

    Very smelly diesel engine

    Slight oil in coolant + coolant light on my S3

    From what you describe, I would agree with Paul@Unit 9; it's the oil cooler. Do it sooner than later too, as getting the oil out of the cooling system is a very tricky job. It is quite a common failure and beware that you may find the cooler design has changed and the hoses on your engine may...

    Very smelly diesel engine

    I get exactly the same. Same car, same year, 130K miles. It can get so severe as to choke and burn your eyes. Putting the cabin air recirculate helps some, but is no solution. I have looked for an answer many times and not found one. I am now of the opinion it is gas escaping from a worn...

    A3 2.0 tdi inlet manifold

    I have this badly worn manifold the the swirl flap rod exits too. It is spitting all sorts of oily gunk all over the left hand side of the engine bay. The cabin now stinks of diesel and recirc gasses and I'm sure it must be bleeding away the turbo pressure also (at least on no. 1, as gas pours...
