hunting DPF

They do mate, the tappet cover has a very complex oil separation system, but it's hindered by both space and heat, the remote catch can being a bit cooler is a big factor.

Wasnt aware of that - good info, thanks.

After seeing how much crud was in my intake manifold after only 35,000km im very glad I cleaned it out and fitted my catch can. When I removed the intake parts again recently (at approx 70,000km) there was nowhere near as much crud in the intake (probably only 20% of what was there before) and it was much easier to clean this time.

Here's the early MK6 Golf TDI rocker cover breakdown, I'd expect the system in your beastly SQ5 to be considerably better and much higher flowing.

Still smoking So despite reconditioned turbos and a cleaned DPF, I still get smoke out the exhaust after a long drive when taking off at a set of lights. The mechanic has had the van back twice and can't find anything wrong, thinks maybe there is still oil in the back half of the exhaust. I'm still getting some (intermittent) impressive plumes of smoke 1000+ km later, could it just but residual oil still burning off? Any suggestions for me? Thanks

My old T4 (petrol) gets that puff of white smoke on take off or right hand corners because of leaky valve stem seals.
I left it because of the difficulty of changing them.
