There was a letter in the Sunday Times Drive section this week about s/h Phaetons, if you can get hold of it.

Webby, DPF 101 pay attention...

Diesel Particulate Filter. Basically a soot collector. It's part of the exhaust system, so technically a few bolts to change. But...

there's a couple of catches. They are designed to self clean or regenerate. For this to happen, the engine must be fully up to temp, engine speed becomes raised, as they regenerate by adding fuel, which ignites in the filter, burning off the soot. Ideally this happens whilst cruising along a nice empty motorway, not just as you arrive at the shops.

Unfortunately this is the real world, not and ideal second universe so the DPF will clog up and fail, then you're looking at stoopid money for a new one, the posher the car the more ridiculous the price.

Tempting as 60+mpg is, I could, and would never, ever consider a diesel for a taxi, unless it was brand spankers and I was able to bin it when the warranty runs out. The reason being simply that the fuel savings won't cover the inevitable repair costs.

Whilst the Phaeton, on the face of looks like the bargain of the century, something tells me it will be a liability to anyone one a budget, unless they can afford to buy new.

Tempting as the Phaeton is, the ruinous repair costs aside, the typical VW mismatched armrest/door handles would do my head in, my £12k Altea would have annoyed me more if it hadn't been so cheap to buy:-X

Can safely say I'm with Tunnie on this one

Chris, in answer to your earlier post, I was refering to your choice as much of a hell raiser as Webby is, I can't for the life of me imagine his parents in a VXR8  whereas I think the Phaeton would probably end up irritating the hell out of you, simply because it isn't LS powered

you may be surprised.. all agreed including commas

There must have been something in that storm

[Webby the Bear]

Affecting you to, you agreed with me

Dpf regen description is not totally correct, the ECU late injects fuel which increases exhaust gas temperature (no burning in the filter), this is done via both altering the injection ratio and also by modulating a throttle butterfly and /or swirlflaps. Revs are unaffected but optimum regen occurs at above 2000 rpm hence the recommend driving approach.

The heat causes the soot to burn and form ash which is expelled out the exhaust

Think Mark implied these are a big job on these, no doubt replacement of them. But depends how far up the zorst they are 

I understand they drop unburnt fuel down there to ignite, get the cat hot and burn off all the crap. If that could not shift it, if removed, could it even be cleaned?

Other things put me off diesels, such as turbo's when they fail that is a buck load of cash. Something to be said for the "simple" 4pot/V6 setup, no DPF, no turbos, just keep feeding it fresh oil 

Couldn't agree more. I have only very basic theory of diesels and the most I've don't on one is a service. The turbo is also something I am concerned about. More to go wrong!

However, i'll take all the advice on board and check out those sites that pscoco posted 

Turbos are reliable, no issues there (as good as the oil changes are, given four bloody timing chains they need to be good).

Modern diesels are fine IF your journey style suits

[Webby the Bear]

Thanks Mark.

Strange that new phaetons aren't offered in petrol form anymore according to the vw site...

Makes sense as to why theres only a couple on das trader

Well it was DPF 101 Thank you for the correction though

I still don't intend to own a dpf fitted car any time soon...

[Webby the Bear]

Taking all in to consideration and that there appears to be a lack of present and future phaetons for sale...... i'm presuming everythiong we've discussed would apply to a Passat CC (just thinking of compromising if we cant find what they want)

They are still offered in Germany. Petrol engine is referred to as Ottomotor after the co inventor

[Webby the Bear]

....just allowed myself to look at Tunnie's Jaguar option. XFs. Mmmmmmmm

Not an issue on Astra, (not all had them) Vectra and the like with the 1.9, simply reset ecu and reprogram with the no-dpf option, open dpf, smash shit out of contents and weld back up
