Seat altea FR - diesel particulate filter

Right, you gotta drive so fast/high rev for so long, but what about if it's a bad winter, icy etc...

DPF sucks.

You generally don't have to drive fast or at high revs - you have to drive at a constant speed. Mine clears after a few miles even at 40mph.

Both the A3 and X type have auto gearboxes. The main noticeable effect of regeneration is an increase in idle speed to about 950 rpm (up from 750) and a jerkiness with gearchanges. Changing to sport mode reduces the gearchange problem. The X type also sounds like the exhaust is blowing.

Most X Type diesels do to be honest!

I work for a diesel engine manufacturer and my own opinion pn DPFs is that they are good at removing particulates from the exhaust stream entering the environment. BUt current technology does rely on regens to keep the device clear to be continued in service. The requirement for these type of devices came from legislators wanting reduced emissions and not the manufacturer, despite the fact that recent non-dpf engines have particulate emissions around 90% lower than a decade a go. With dpfs it's more like 98% lower.

I really feel for the OP, this is bad luck. The instruction tried to get into the engine operating envelope for a regen, but I know from that getting this on a normal cycle for certain customers can be difficult.

You sound like you have an alternative suggestion to the current regen method...?

Not mine. Without doubt the most refined 4 clylinder diesel I've ever been in.

Surely it is to use the Ad Blue additive. Which is expensive and harmful.

You have my sympathy as same happened to me, but after contacting trading standards for advice, I contacted the dealership where I purchased the vehicle and outlined the unsuitability of the car for my needs ie stop start driving and the fact that no mention of this potential problem was disclosed to me at the point of sale. The car was clearly not fit for purpose and the manager agreed, he offered me petrol alternatives which I declined and after requesting all my original outlay back, it was agreed and a cheque received. He also said he would have the sales force re trained to outline the suitability to potential customers of this type of vehicle in order to eleviate future problems.
It has restored my faith in human nature as there are still decent garages out there that give customer service over profit. Always take advise and use recorded delivery when communicating with third parties.
Good luck
Tony.

I think the general public need to be retrained when buying diesel cars as, unless you're doing
30,000 miles a year then there is no point getting diesel.

So many customers say "Oooooh but its the economy..."
