DPF...Can I
remove it from the ECU using Vagcom?
Reason being I have been reading about low ash oil required for cars fitted with DPF, I've also been reading that low ash 0W-30 oils can cause premature cam wear. Personally I am not keen on 0W-30 oils as I feel they are just too thin and don't provide enough protection, so I would like to start using 5W-40 505.01 spec oil instead. So now I would like to code out the DPF and remove the filter.

There is nothing wrong with 0W-30 oil for everyday use. Cam wear was a problem with V6 2.5TDI engines. This was combination of design, higher then now sulphur content in diesel, incorrect oil usage and long service intervals. Using long life service and doing little miles in short distances causes oil dilution with diesel over time. If you change it yearly there should be no problems. And 3.0TDI(as does later 2.5) uses roller rocker arms so no cam wear issue. 0W-30 PD oils have high pressure additives which ensure there is no metal to metal contact and reduced wear on components.

I believe 507.01 spec oil is required for a DPF equipped engine regardless of service intervals.

I'm confused.
I thought that the removal of DPFs, or any other original emissions equipment, would result in a MOT failure from this year onwards, so how does this work?

Judging from the amount of soot routinely being blown out by diesel powered motors, the smoke test limit must be pretty relaxed.
 There seems to more black smoke from some cars than a marine Deltic running in the "oil throwever" range. Fortunately (or unfortunately??) there doesnt seem to be a similar propensity for exhaust funnel fires.  .
