DPF FULL???

Simple, just get the petrol version. No DPF problems, no smelly fumes, better for the environment, and they go like clappers, not like a slug. I wish I'd bought one instead of the oil burner!!!

Not better with respect to CO2, indeed a lot worse, only 'better' with regard to particulates and oxides of nitrogen, both of which have localised effects. So, are we to worry about the atmosphere in cities, or global warming??

LR-Evoque, I never had the DPF Full light come on in mine but was advised that it should come because the sensor thought the DPF was full. Mine failed at 70+mph on the motorway ½ way through a drive from Newcastle to Glasgow, I got the reduced power waring and suddenly the car speed was restricted from 70+ to 30mph in the outside lane.......... it happened 3 times in all and the only warning was the restricted power warning on the dash but it was the same cause each time..... I rarely do any city stop start type driving most is A Roads with 60mph speed limit and free flowing traffic, I have never noticed the DPF on any of the 3 cars I have owned ever going through a regeneration cycle.

Seems these are the weak spot with all oil burners these days. The German car forums have plenty of posts about issues with DPFs, especially VW Audi. Best solution is take your car to your nearest performance shop and have them remove it.

Unfortunately here in Europe it isn't as simple as that as we have government emissions testing that requires that if a vehicle was built with a Cat or DPF to comply with regulations then it has to stay. Interestingly my 1996 TDi300 was built with an optional cat which when the downpipe corroded I didn't need to replace. I wonder if the problems with VW group DPF's might be something to do with the 40 times the tested amount of particulate and greenhouse gases the cars were claimed to produce..........

Tim, was that 'breakdown' because the sensor had failed?

Yes and I could "cure" it temporarily by pulling over and doing the system reset, switch off the ignition for 10 minutes and then start up again causing a reboot of the car's systems, that got me up and running normally often for days and days and often until the dealership had got a new sensor into stock to replace the damaged one.

Thanks Tim...useful info. So I'm guessing had the sensor been good you would have had the warning lights up. Did that sensor cause irreparable damage to the DPF/Cat? or were you able to carry on just with the new sensor fitted? i.e. after it had re-established normal de-clag cycling.

I don't know what the dealership did. I did suspect a problem with the electronics rather than the sensor as it seemed to fool the sensor that the DPF was full when it wasn't. I delivered the car to the dealer and they replaced the sensors and I drove it away several hours later until the next "failure". I sold the car in March and I haven't had any calls from the dealer to ask if I had any problems so I assume that whatever the dealer did before selling the car on cured the problem......... and I called on them last weekend and all that they said was that the buyer was delighted with the car! All I can assume is that something was done between me selling it and them shifting it on but I was fed-up with the problems and numerous rattles that simply shouldn't have been there on a £55,000 car and were inexcusable after 3 years of production.

Thanks again Tim. BTW why do you still have this compulsion to lurk on here (BRR & RRE) with all the poor relations? Don't you have your mind on higher things now?
I understand you have previous but I think you just can't let go of all the beautiful people on the dark side.
All the best

P.S. Your advice is much appreciated - by all I'm sure.
