Multiecuscan

Shame you drilled a hole to the dpf, if you connect the differential sensor hose with a t-piece both to the first connection there should not be a need to drill a hole.

Any idea why it's in limp mode still with no EML or DCTs?

Also any idea why it won't regen? Bad software for this ECU or is it a parameter that is out?

maybe someone already "tuned" ECU and that's why you don't see any DTC?

if modded ecm try to downgrade to the original and check wich DTCs send out, May be someone turn off faults codes

I meant I wonder if it's a bug with MES?

The ECU map is very likely to be stock as it's previously thrown up codes for EGR and DPF.

Can anything else cause limp mode without a fault code? If the car had previously failed to regen a number of times and then went into limp mode with "engine failure" EML DPF light etc, would this then require a successful forced regen to get out of limp mode?

Thanks

take it for a drive on highway - warm up engine, speed at least 60km/h, rpm at least 3000 and drive for about 10-15km in such conditions. should burn and clean DPF if it's clogged to much.
