DPF

[Devon Jim]

Hi all,

Ty for this forum.

I have a 2014 Toyota Avensis D4D 2. litre.

The car is a good car but I do many business miles in it and it has clocked 150k, pretty much fault free bar an alternator and a DMF advice would be appreciated.

Bar one forced regen the DPF has held up well.

I use fully syth oil and change it every 5 k, above the service interval plus cleaning the EGR valve.

The regen cycle is getting shorter, presumably as it ages. No lights have come on.

As I understand it this is ash rather than the combustible soot. Should I put some DPF cleaner it? Could this upset the chemical balance?

Also is there a way of getting ash out of the DPF?

Hi,

DPF cleaner additives can only help any soot to burn off, they can not do anything to non-combustible ash. DPFs do fill up with ash over time and eventually need replacement due to this.

There are companies which specialise in cleaning ash out of DPFs which can help to prolong their life, although I understand it doesn't totally renew them, just makes them last a bit longer.

i can only talk from experience...

my T180 (2.2DFD 177) 2006, 180K just had the dreaded p2002 particulate bank trapped code confirmed, bad catalytic convertor confirmed by the dealer.

I had no fuel consumption warning of this, no eggy exhaust odours, or uneven acceleration of the problem.

Am being quoted about €2200 for a replaced new cat.

Here's what I struggle to understand, the aftermarket part sites quote between €300-600 for a new part, eg a Walker CAT.

How can Toyota charge so much more on the item? is it really that different, that much work to put it on?

my other local alternative is an ultrasound bath deep clean of the part cut in half, then welded together again for about €150 - that excludes disassembly/reassembly to the car by an independent mechanic. I'm reckoning the whole thing could cost me another €120, call it €300 all in.

What would you do? repair or get a "cheap" new aftermarket one?

Depends on the value of the car to you and its reliability I assume. I have decided to replace my DPF through the dealer with their one year warranty. It has cost £1500 however that includes complete fuel system cleaning. They have seen no turbo problems so I went ahead.

I would ask for assurances that they will sort any problems out with a warranty, at least that shows good faith.
