A guy at work has just had the nice experience of needing to buy a new DPF for his Passat. He was wondering if it had any value to him in keeping it for scrap etc.

Anyone any comments?

Cut it open and remove internals! Then weld back up!

Fit onto car and remap with dpf delete! Then sell new dpf!

Or do that at the start and save £££££

I would have just had it gutted and mapped out. It will only clog again.

Did they fix the problem as to why the dpf clogged up or did they just a fit a new one to do same again

The driver was the problem

Not sure to be honest, but he had heard about whether its still legal to do it. DPF delete that is. He'd been told about it being classed as defrauding the tax system and police now carrying basic means of testing.

He had had the car a good while I think and does rack a few miles up.

How do you work out that Jase?

Anyone able to answer my original question without a smart comment?

Just worth the value of the weight of the scrap steel, so probably a couple of quid at the most. Unlike catalytic converters they contain no expensive metals worth recycling.

Thought it would be the case, many thanks

Which makes their £1000+ cost to replace even more of a joke.

No, i didn't say it didn't cost anything to manufacture, just that it isn't worth anything as scrap.

A CAT uses platinum as the catalyst, which is a "rare" and expensive metal which can be recovered and recycled, therefore has a (relatively) good scrap value.

DPF's contain a filter made from ceramic fibres which can't be recovered or reused and therefore are worthless.

what something costs new has no bearing on what it is worth as scrap value.
