Audi, European design, parts may be hard to find for this, I suspect the automatic choke assembly is faulty, hence giving you the wrong combination of air and fuel mixture causing the smoke. You could however, if you are willing, to remove the assembly and try lubricating and cleaning it, as it may have carbon build up blocking the channels inside. Hope it works, Good luck

1998 VW Golf Tdi idle problem, it starts fine wean cold but as soon is hot does start up to 1100 revs for about 2 minutes.


sounds like a failing o2 sensor. or MAF sensor. but it could also be a blocked egr valve, its common on the tdi over time. sometimes don't even register as a fault on ecu codes.

A lot of white smoke and engine dying could be bad head gasket. Search 'symptoms of head gasket failure' to make sure before you run it again. Good luck

My car is blowing smoke and shuddering ef falcon


What color is the smoke ? is it bluish or is it white ?
The blue colored smoke would smell more like burning oil, which would indicate a broken piston ring, ect. the white smoke if it smells of coolant(anti-freeze) would lean toward a head gasket problem.

first check your glow plugs that they are not faulty,if faulty replace them,then get a bottle of injector cleaner and put it in your fuel take and replace your diesel filter,and also change your oil and oil filter,maybe your hydralic lifters are not preasurising when cold

Mazda bravo blowing white smoke


blowing white smoke is almost always a symptom of an engine coolant leak at the cylinder head gasket. remove each spark plug and look for a dis-colored plug to find which cylinder is leaking.
