DPF removal, new law!!!

[jcbmally]

I have enquired about DPF removal and it sounds promising, however the law regarding MOT's has had slight changes from Feb 2014. The change states that the DPF will be checked and the vehicle will automatically fail the MOT test if the filter had been fitted as standard but is found to be no longer present.
The company that can do the DPF delete say the cut a piece out of the pipe , remove the filter, replace piece in the pipe, ECU updated, done.
Can the filter be still checked by the MOT inspector?? If so how??

I think you'll find that they'll have a list of all vehicles which were manufactured with DPF filters, so if not present, your car will fail the MoT. Can't see anything to be gained really, I haven't heard of any big issues with Exeo DPF's?

A lot of the companies offering DPF removal advertise that they cut out the filter, weld up and grind off any traces of the repair. Apparently they leave the exhaust looking factory!

If the not centre can't see any trace of the removal, would they be able to tell any other way?

I have been told they might be able to do it via the OBD port, if DPF delete has been carried out then they will know. I suppose they will have a means of finding out sooner or later, after all it is VOSA.

If you've removed the DPF, wont it smoke a lot more when being tested?
My Golf PD150 (no DPF) smoked when booted hard, the Exeo CR170 with DPF is clean as a whistle.

For an MOT test they're not allowed to connect up to the OBD port. The check for a DPF is visual only, and the tester will look to see if the DPF is there. If he sees one then that's it. If he can't see the DPF because there's a heatshield in the way or something, then he's not allowed to remove anything to check (not even a road wheel).

So as long as the filter is there to see and the vehicle passes the smoke test, then it's okay. However, if you get a VOSA inspection at the roadside (or called into a VOSA centre by the Police) then they can find out.

Id be more worried about smoke and emissions without a DPF. as the DPF does stop the black smoke associated with a diesel
