Anyone here deleted their diesel DPF?

Just noticed this. It appears to be an MOT failure now. No idea if this is old or new news but I know some of the diesel guys on here often warn of DPF issues on diesels.

Depends on how observant your tester is I guess

While we're busy inspecting cars to find those seven filters that have been removed, China builds coal power plants everywhere

The decent 'deleters' actually knock the DPF through and just leave the shell in place and then just 'delete' the DPF in the ECU.

Do you have to connect the car to a keyboard in order to do this?

Have a delete on our Leon TDI using a milltek pipe and a remap. Yes you can knock the dpf through and get someone map it out for you. If you want a proper job go to Sh.ark performance, Darkside Developments or RS Tuning. Depends if you just want to get rid of the dpf or make some gains at the same time.

In the grand scheme of things, is much available with a DPF delete? On the 535d you are talking 5% best-case.

Do you mean is the extra gain with a dpf delete worth it over a bog standard remap without delete?

1. Get pipe replacement
2. Keep Orginal DPF
3. Remap ECU
4. Put DPF back b4 MOT
5. Profit :]

I can't see it causing many problems, it's just like having a decat, there's a million testers out there who will turn a blind eye.

Do you just look them up in yellow pages under dodgy MOT?

I would imagine a large percentage of enthusiasts will have friends in the trade or know someone who knows a lenient tester for such things.

like most things as long as you leave a human element in the mix theres always going to be ways round things.

Why the recent trend for the word "delete" when people are talking about removing parts from cars :confused:

Simplify, then delete heaviness!

This is what swayed me to buy a petrol over a diesel really. DPF's are going to cost loads to buy with that law out now so IF they can spot a gutted one you won't have much choice.

I've been wondering the same.

86JR · 2 Mar 2014 at 20:20

Well if you are keeping a DPF but getting rid of the internals, you are deleting their internals.

snapdragon69 · 2 Mar 2014 at 20:46

I had mine hollowed and the ECU reflashed to disable the monitoring and regeneration. No problems with main dealer MOT, as (to paraphrase) the MOT tester's manual - the tester is to look for obvious signs of removal and if not sure assume all is well.
