When I drive that car it produces masses of black soot

When you granny it, soot deposits build up in the engine. When you thrash it, the deposits get burned up and blown out of the exhaust, which is the smoke you see. It shouldn't do it all the time. And VAG engines do not smoke any more than any other diesel! Take it on a long fast trip and you should be fine at the end. If it's really bad you might have to clean some stuff like the EGR valve out manually, or some sensors might be clogged up so they might need a clean too - but I dunno.

ok, ta.

[i]And VAG engines do not smoke any more than any other diesel![/i]

Nah, not all diesels produce smoke. Once my Honda is warm I can cane it with no obvious smoke at all.

My VAG doesn't smoke either.

Sometimes you get a puff from certain cars, this I suspect is a bit of over-fuelling to spool the turbo up as fast as possible. Most produce a very fine blue haze when you floor it which you can't see at all unless it's night and someone's behind you with foglights low down.

Hondas are supposed to be pretty clean tho.

I opened this thread with some trepidation, but find I am bored, not disgusted.

Swirl Flaps, have to like that - are they connected to the Flanges ??

Haha, no worries, I'm a diesel calibration engineer by trade so it's te sort of thing I could talk about for hours!

SCR systems are reasonably simple really - it's just like a normal catalyst but needs urea sprayed on it to convert the NOx to NO2.

How do you fill that SCR system up then? ๐Ÿ˜‰

the reason your diesels don't smoke is because they have a dpf to reduce the smoke. If you whipped that out, you'd see a puff on accelleration like anything else.

My 180,000 mile mondeo is great for leaving a smokescreen. someone a bit too close behind on the motorway? 3rd gear, boot it. Car doesn't actually go any faster (it had all of 88bhp when new. I doubt its got 50 now) but it annoys the guy on your bumper

My diesel doesn't have a DPF, and I do sometimes (but not always) see a puff on acceleration at night. But of course I am not always looking and I also don't have a good view of the exhaust from the driver's seat ๐Ÿ™‚ Certainly can't see anything in the rear view in the daytime.

What make of car is VAG??? ๐Ÿ™„
Why not just say VW or Passat, as that's what it is? Or does it make it better by association with an Audi?

VAG is easier to type than "VW/Audi/Skoda/Seat" and they all have the same engines which is what this thread is about ๐Ÿ™‚

Yes, I know what it means, but YOU have a VW Passat, so why try and hide the fact.
Actually THIS thread is about BMW's, NOT VAJ's. ๐Ÿ˜‰

If I was trying to hide it I'd lie about it on here and you'd never know ๐Ÿ™‚

I can start a thread about Vaj, I'm away for the weekend so the 3 day ban is worth the laugh. ๐Ÿ™‚
