Mercedes sprinter problems help required

[colinrob]

I have two Mercedes sprinters a 13 plate that every 300 or so miles goes into limp mode and eml light flashes suggesting it needs dpf regeneration, it has been statically regenerated twice now 300 miles later light flashing again, I also have a 10 plate that drives like it is in limp mode but the engine management light has not come on
Anyone know any expert in the Bedford area that could possibly diagnose these problems
Thanks

This is a problem that we had with one at work . Light on then limp mode . Turn it off then wait 20 mins and everything would be normal .
Despite many visits to the dealers nothing was ever found or changing all the normal suspect parts made zero difference. Just as you thought it had gone away up it would pop again.
