If it works, nothing much more then that on full throttle, just so its visible, where as before, it was not..

Original purpose of video was to possibly pick up the noise level increase on idle

Have you got any more videos please?

Possibly of it being revved?

Thanks

That's a nice looking motor!

Kinda hard to film the exhaust the rev! ill wait till im with the other half

and me. But to the OP, any visible smoke on a modern High Pressure DI TD is baad news. DI is the industry solution to emissions of diesel kinds, a DPF can only be fitted to a low smoke emission engine so gives you and idea how far diesel tech has moved on. You can thank BMW mostly for that by sticking their noses out back in the late 90s.

Hmm, my Euro 4 engined 2002 (52) BMW 320d SE 150bhp (E46) used to smoke like a truck under hard acceleration.

To a point one day, I hoofed it to overtake and the 'down-pointing exhaust' actually left a long black line of soot on the road surface visible from my rear view mirror.

At night it was also much more obvious seeing it in the headlights of the car behind...

Given a choice I would actually prefer to keep my DPF (I know that I am the only one by the way! )

I don't want other road users to see how hard I'm accelerating or when I'm lifting off, in a non DPF equipped diesel you can see every single throttle inut from the car you are chasing following , I don't want others to know how hard I really am trying!

Im the same Silver, i like the idea of a no smoke diesel but this being the real world and all my DPF decides to give up the ghost :( On the face of it a DPF is a good idea but they need regenerating too often for my kind of work and they cause more hassle then good!

Did someone mention on here about by me taking my DPF off im a direct result of cancer? Shut up will you... considering white bread can also give me cancer im not going to death by firing squad just yet

You may not care about the environment, but you should care about getting cancer especially if you can avoid it

So u do use ur Vrs for a taxi?

I knew i read it somewhere!

And no my vRS is not a taxi but up north about every 9 out of 10 taxi's is an Octavia, hence why my car gets called a taxi by people who are about as sharp as a spoon, i just embrace this title

With you on wanting to keep it (while its working fine) mainly because doesn't it cause hassle as far as Insurance and MOT (smoke test) goes?

Was it a direct injection?

The point was that BMW was one of the first to invest in diesel engine technology and make it more marketable. If you think back the early generations of TDs of that period, there was a reason why the pipe faced downwards, primarily because the mechanical injection system simply over fuelled on WOT. The advent of high pressure direct injection means a much better control of fuelling and a cleaner burn can be achieved, so a DPF has a chance to work. Doesn't necessarily mean that smoke would be totally eliminated from a diesel engine without a DPF, but it shouldn't be belching black clouds of the stuff.

You do realise that removing the DPF will result in the car failing an MOT. (As of 01/01/12)

no it won't, it only if the cat is removed from a petrol car . as long as the smoke limits are met 3.0 before 01/08/2008 and 1.5 after its fine

Yes it will because it was a part of the exhaust system when it was built, it is classed the same as a catalytic converter on a petrol car.

The rules now state that it if was there when it was built it has to be there on test. Otherwise it's a fail,

that not what this says http://www.dft.gov.uk/vosa/repository/Special%20Notice%203-12.pdf

Clarification that the check for the presence of a catalytic converter only applies to petrol vehicles that

qualify for a full catalyst emissions test regardless of the result of the Basic Emissions Test

And a relevant thread on a BMW-owners forum:

I had my DPF internals removed by JabbaSport and a custom remap installed and every now and again a puff of smoke comes out the back. From my experience it is normally after a long period of light throttle imputs. I work away from the UK for months at a time and my better half is the only one driving; she has a 20 mile comute to work and it is a very benign drive so usually for the first 10 miles or so when I get back in the car there can be the odd smoke bomb out the back end. After that its just the usual small waft I mentioned earlier.

The car will and has passed several MOT's now as they only check to see if there is a DPF shaped filter (internals removed is NOT checked) present, and they do a smog check.

All in all I am truly happy with what I have had done and my car feels like how it should have left the factory in the first place.

How much did it cost Fitz (if you don't mind me asking!)?

Maybe 'Honest John' is as dodgy as the next back-street car dealer

Might want to ring VOSA on that matter..thats what i did and no i not need one but its still needs to pass the emissions/smoke test

Honest john is good for what to look out for when buying a car, not MOT's, thats VOSA's dept.

Think it was in the region of £700. There was a topic on here many moons ago and I'm pretty sure I put the price on it.
