Unburnt diesel: temp sensor could be reading low-low, thus over-riching things.

MAF or something electrickeral NEEDS to be detected by VAG-COM.

Might be losing compression on the motor, but I think that's extremely unlikely.... unless it has a chocolate cam....
Just because you're offended doesn't make you right.

It does sound as tho it is misfiring when cold but does level out when it gets warmer but still smokes! i was reading here about the glow relay, just been

out again to see how long the glow light stays on, it stays on for about a 1 second is this right or sould it stay on longer ?? looks like i'll have to repair

the car and then take it to get the falt codes checked.

If your running it without water you will kill very quickly.

Until you've got a new rad in there you're not going to be able to get situation normal as far as the engine's concerned, so sort that and then take a view.
