Title: golf gti 02 smoke on cold start
Post by: serlac on 06 March 2014, 17:29

hi i have an 02 plate golf 1.9 gti , when i start the car up from cold i get a small amount of whitey bluey fumes/ smoke , it then progreses with time to get worse .  if i drive the car off from cold straight away from ignition the smoke clears after a few minuits. it is burning diesel most defenately .

the car isnt losing coolant, no oil loss, no coolant mixing with the oil , i have had 3 garages look at it one told me me it was stem valve seals , another it was the turbo , and finally vw dealers did a diagnostics found no faults, but said it could be the head or the turbo , as turbo sounds a bit noisy. the car has done 72000 miles has had an engine flush, fresh quality oil , injectors have been cleaned with some kind of cleaning stuff that attaches to the fuel while the main tank gets disconnected.

question is where do i go?, do i get a pressure test for the cylinders and while head is off replace the stem valve seals and the rings? , or do i replace the turbo ? , or anyother possibilities ? .  the car is 150 bh which has a common fault with turbos it does sound a little noisy . any ideas would be welcome thanks

White smoke means water, blue smoke means oil

Do a compression test for the first thing you do, then go from there

I would leave it for now and see if it gets worse. Also i would get the car up to running tempture half way on the tempture gauge and give the car a good booting to clear all the soot out of the exhaust. Also never fill the oil up to max .
