My 2015 VW T5 has developed a problem over the last 24hrs. White smoke bellowing out of the exhaust. Moreso when cold, but as the engine warms it reduces alot or even completely disappears. Oil looks OK – black but within the min/max range so no significant loss and no signs of mixing with water.
It’s a 2.0 TDi in 102bhp guise, with just under 40k miles on the clock.
My initial concern/thought is HG but I don’t seem to be losing any water, if I am it is a very very small amount so not noticed any water loss yet.
No other signs of any problems – no power loss, no hesitation or mis-firing, nothing on the dash illuminated to tell me something is up. All running just fine apart from the visible white smoke.
My other suspicions is turbo oil seals, but if that was the case i’d expect the smoke to be grey or even black from heated/partially burned oil in the exhaust – not sure if this assumption is correct though.
Can’t think of much else other than something to do with the horrendously complicated modern diesel exhaust systems need these days. I don’t think it is the type that needs Adblue, again nothing on the dash to indicate it needs it, and not spotted an adblue filler anywhere.
Read some stuff on fuel injector seals.
Any other ideas? It’ll be going off to the garage tomorrow so just looking to see what I can rule out for now.
Not sure if the van is still in warranty with VW or not, I suspect in typical style it has only just expired.
Whatever it is I suspect that is my new bike kicked down the road again!
Cheers all.
