What I don't understand though is all these modern hi-tech diesels still seem to make quite a lot of smoke when accelerating hard, especially when passing cyclists and arguably more than my old 1.9TD so I question if all this hi-tech stuff actually works and what they'd be like without it - factory chimneys I expect!

Followed a 56 reg Jaguar S-type last night that was chucking out huge volumes of black smoke at quite low speeds and acceleration (30 zone).

Dead giveaway IMHO, probably saw the cost of a replacement and balked!

Marc,

Excellent, thanks. Most interesting and informative

One assumes that when the MOT regulations change to monitor DPF performance there will be set standards for cars to reach and those standards will not apply to older diesels that have no DPF...

This would, I assume, have severe implications for those who have already disabled their DPFs...

[GiveMeABreak]

Exactly my understanding Jim. They know what cars have DPFs fitted as standard (just as the tester's PC tells him that there is an electronic handbrake fitted for example) and also what the emission parameters are for each car based on its certification at new - so it's not that our cars will have to pass any new standards - only meet those set for our cars as per the certification.

Yes, exactly what I have been trying to say in another thread - that those who have had them removed will have the expense of trying to get them refitted and the ECU remapped again - or scrap their car! As I said in the thread, I was offered DPF removal as an alternative on a previous C5 when it had horrendous stalling and engine rasping noises once - which turned out to be a very small hidden hole in a turbo hose! That was quite a few years ago now, but being slightly more educated as to the purpose of a DPF now and the job it does, there is no way that I would ever try and cheat to save a few quid - and now this will likely be very difficult in 2017 when they are supposed to announce the changes.

DPF Removal - Better Think Again

I'd not seen that thread Marc... More education for me on this topic!

This thread has gone from being interesting to being VERY interesting.

Thanks chaps

I quite agree Maurice! Enjoyed this one immensely and learned a lot.

Topics often do get more interesting when allowed to wander a little off-topic

Couldn't agree more. A few bits of off topic insight and information makes for a far more fulfilling experience than sticking rigidly to the original topic and saves on the number of different threads.
Not for everyone of course but it works very well here.

That wouldn't happen to be over the channel would it Jim? If it's the one I occasionally use, a single word off topic and instant retribution!

It's the vintage wireless forum Marc...

[GiveMeABreak]

... definitely not the same one then Jim. My Grandad used to build his own - as a kid on rare visits back from abroad, I always remember spending hours in his garage just looking at all the valves and kit he had!

You'd love my place then Marc. I still work with valved stuff extensively I sit here surrounded by them as I type this...

I don't mind telling you how irritated I get when seeing clouds of blue smoke comming out of bus and other vehicle exhausts including the two wheeled variety, when we spend our hard earned on Eolys etc. Perhaps its an age thing.

On the Cactus topic i would like to see coarse wet and dry type material applied onto those door panels for the 'benefit' of the door edges of those who wang their doors open against other cars without a care in the world.

Well said - 'Renegade' has just had his (new to him) C5 X7 door dented in at his local Sainsburys. I had a similar issue at Aldi a few months ago - somebody obviously can't park and left a load of their paint on my door and wing. Thankfully I had a lot of canuba wax applied previously and that helped remove the paint. Extremely annoying and it is times like this when I wish I had electrified bodywork when parked that would give anyone getting too close a good jolt!
