Diesel Exhaust fumes in cabin from DPF

[T5 Damo]

Just wondering if anyone else gets the awful diesel exhaust fumes in the cabin of their T5 Transporter when the DPF self cleans itself? And also do you get a rough idle also when it is cleaning itself?

Damo.

Maybe I should read my owners manual.....but when does it clean itself?

When it gets a bit restricted (filled up with the soot) simply said, in addition to that, the longest km without regeneration is 900-1000km.
Which means, if you drive on highway only the ECU will regenerate the DPF every 1000km approx. The smell and increased idle speed are the signs that your DPF is being regenerated.

If you turn the air recirculation on, it will keep the fumes out. Also keeps dust out when driving on unsealed roads. If it's on for prolonged periods of time, you will need to wind the windows down occasionally to let fresh air in. See warning in hand book, Controls and Equipment page 86.

Cool, it doesen't bother me i owned and drove a 77 bay window kombi for ten years, now there's an engine smell. still suprised it comes in the cabin though. Can't complain just got another 970k out of 70 litres again.

Now mine is a 2005 and doesn't have a DPF and I get an exhaust smell in my cabin, its a 2.5 diesel.
Any ideas???
Thanks

Cracked exhaust manifold would be the most likely culprit.

Fairly common issue with the T5 2.5 engine there is a write up somewhere i'll see if I can find it .Found it !!http://www.vwwatercooled.com/forums/...d-59267-3.html

More likely a slightly loose clamp post turbo where the DPF joins it. Mine was loose a while back and no more fumes in cabin when the allen bolt was tightened. Cheers, Scott

One of the other issues with diesel fumes getting inside is that the vans are hardly what I would call sealed from outside elements . When I fitted sunroof to our T5 after about two years the grey roof trim was almost black in colour ok slight exaggeration but the velour was acting like a filter and wherever it was no longer glued to the backing board as we have to cut part of the original trim away , but that's where the fumes were coming through and leaving the soot in the fabric . There are many parts of the body which are open to the air outside , logic dictates if the van is putting out diesel fumes other than the end of the tail pipe it will come up through the vents and the body .

Not sure the Transporter has active cleaning of the DPF.
Perhaps the crafter might...
I only say this as I had the DPF light come up on the MFD a few days ago.
I checked the manual, which said to drive for 15 mins in 4th gear, above 70km.
Low and behold --> it worked (I did go into 5th & 6th at higher speeds, but essentially high revs)
Warning light now off.

What you describe above IS active DPF regeneration. The warning light comes on if the normal, no light, 40% active regen doesn't work and it gets up to 60%, then the light comes on and it won't quit regenning till it gets back down. If you turn it off mid "light on" regen, it will start again on regen next engine start, from cold!

All VAG SiC DPF's have active regens built in at set % fills.
