Hi everyone.

Would really appreciate some advice:

I have a diesel 1.4 Polo 2004 and up until recently has been running beautifully.

More recently however, i have noticed that on start up first thing in the morning, the car has a strong judder, shaking kind of sensation from the engine. Its strong enough to shake the whole car. Accompanying this is smoke, like a greyish kind of smoke from the exhaust. Its fine once i start driving and the car warms up but this appears to be happening at the moment every morning without fail.

It has been serviced regularly therefore has had good engine oil, filter replaced and so on but this issue has remained throughout services.

Anybody got any idea what it can be?

Any advice appreciated.

thank you
