DPF removed and new MOT checks May 2018

Recommended Posts

I have a 2006 e60 535d which was bought chipped to 384 bhp with DPF and EGR deleted.

the car sails through MOTs and is a joy to drive. Best I think I've ever owned.

I have seen in the press etc that there is a proposal to introduce a tougher MOT to check there is a DPF fitted. At present only requires a visual check and passing of a smoke test.

My MOT is due in June. Does this mean I will have to find a DPF which has not been altered and also get the software re the DPF returned to acknowledge a DPF is fitted.

I think I won't be alone here and wonder what other people think needs to be done.

I've heard rumour they will plug into the OBD and get live reads, but quite how feasible that is, given the many different vehicles out there I don't know.

One day they might get around to checking, actual enforcement an prosecution might be another story. Wait n see...

Let me guess, the news article will originated from garagewire? Every year they do this. 

 

I wonder if they have a vested interest in dpf cleaning or products related to it??????

Yes Garagewire seem to be pushing this story. Just hope it never happens. Don't fancy having to buy a complete DPF and recode the system to cope with this.

What I wondered was; could you get away with just fitting it for the NOT and removing afterwards. In other words leave software alone.

not sure how difficult it would be to keep replacing and removing the dpf.

Hadn't seen this bloke before, seems pretty factual yet interesting (in a slightly non PC way):

This is an update on an earlier thread I posted about DPF removal and the new MOT checks.

I put my 2006 e60 535d remapped car in for an MOT this week. It has the DPF and EGR deleted

and produces 384BHP.

It did fail the MOT, but on front anti roll bar links. No problems with emissions.

That's after the garage spent over £6k for new equipment to check emissions.

Panic over.....until our leaders have another 'bash the motorist' go at this.

The true test will be when my old one is due in November.

 

I will keep an eye out on that one .... See if that passes as that smoked on acceleration.

Well as far as I know in mainland you can pass the MOT in any licensed/authorised garage/car repair shop

In Here we have a MOT centres like this one https://goo.gl/maps/b57vLfybETy 

 

p.s Someone posted that you could ''be friendly with your local MOT guy'' to pass the MOT without the DPF but this is way different.. .

I had an old diesel Mondeo which I was informed was too smokey to attach to the machine.

I poured a bottle of Wynns mot additive. Passed no probs

just to clarify, I have a 3'' stainless steel exhaust without the actual dpf filter fitted on it... Supposed to be: No filter- instant MOT fail...

They still cant pull your car apart though. So if the emissions are good and the under tray is intact and the engine covers are on, the tester can’t actually see and it will pass.

 

My 535d is similar to the original posters in that it has DPF removed (gutted), EGR removed and recalibrated. It passed its mot too. The garage were aware it was gone. “Should be fine as long as the car is sound mechanically” was their words. Which it is and they had only one month before done some work on it. The garage in question went over the car and then sent it across the road to the dedicated mot station as my garage don’t have a test licence. They are a performance specialist who focus on track cars and time attack cars, mainly lotus and Japanese stuff although did dabble in M cars a few years back.

 

My car didn’t have any advisories. The emissions certificate showed as passed for all ranges but interestingly my car has a dateless number plate and the vehicle year entered into the machine was 1996. Wether that was deliberate in order to achieve a higher tolerance emission limit and thus a PASS on the paperwork I don’t know. I suppose I could look up the limits and compare but haven’t bothered.

 

Ive also heard about folk (vosa) plugging into your obd reader to analyse DPF soot amounts.

 

My map has a ghosted value set into it. That isn’t BS from the mapper as I can read this value myself with Carly!

A proper DPF delete, that's good.

 

Some of the software we have for doing such a service completely emulates a working DPF on some ECUs, so instantly the OBD check won't work.
