Basically I have a Polo 1.4 TDI. Not long been a VW owner.

Its 2007 1.4 TDI with 40,000 Mileage

I was driving this morning along the bypass come to a junction and went to drop down gear and it was revving high and smoking white smoke. I cut it out, started it again and it started and then eventually started smoking again.

RAC, came didnt even really look at it and said its Turbo but I somehow dont think this as its low mileage and has been driving fine no swirling or anything.

Its not driveable and dont want to take it to VW as they will charge me so much.

Somebody please give me suggestions.

White smoke indicates water is sitting on top of a piston/pistons which basically mean water is leaking from one of the water channels and making its way on top of the piston/pistons..... in the short term.. headgasket most likley

The car has only got 40k mileage though. It hasn't lost water either

I have been told its injector failure... diesel and oil mixing?

Oil burning is blue smoke, white is coolant..

Why isn't it driveable?

You can get white smoke from unburned Diesel when the engine is cold, but this should disappear when the engine gets hot. Also, under those conditions, the white exhaust smoke would smell strongly or 'raw' Diesel. This is not to be mistaken for white smoke caused by condensation when the engine is cold.

If your turbo has failed, as has been suggested, you would tend not to have enough air entering the engine, in which case you may well get black smoke from the exhaust.

A half decent Mechanic should be able to diagnose the problem for you, failing that, you may need to get it on VagCom (diagnostic package.)

check the smoke to make sure its not whitey blue if it is take one of the lowest intercooler pipes off and check that theres no oil in it and that will tell you your turbo oil seals are ok

I think the key comments in your post stating that it was revving high and chucking white smoke indicate a turbo failure. Whilst 40k miles isn't much, the life of a turbo is dependant on the sort of life it's had.

I would agree with the RAC man, sounds like a blown turbo.

without care, turbos can go early. they can also last the life of the car. good oil etc, proper warmup proceedure (not revving high until engine is warmed up, letting it idle for a min if its been thrashed around before turning engine off. you dont know what type of life its had before you bought it. if you go to vw they will charge you a l o t.

Right... Garage have told me its Diesel and Oil mixing and the only way this can happen is injector seals or tandem pump? They say this is why there is smoking as its burning?

oil only gives blue smoke it its been combusted, if its oil buring off a hot turbo or exhaust it will be thick white.
