Well eml no longer on . But new problem is twice the doblo has started blowing loads of blue smoke out of back end. Both times as been after a decent run when it's ticking over. If you turn engine off and restart no smoke.
After this has happened twice the engine oil change light came on only done 500 mile from last service not sure if oil service was reset. Checked the oil to find it is overfilled and has a funny smell to it.
Anyone any ideas ?

Have a look at other posts on oil level as sometimes its diesel that's got into the oil because the regen for the DPF has not been completed properly assuming its a diesel with a DPF fitted. Also be careful as they can run on the diesel/oil mix which is not good think they call it run away engine.

Yeh was reading a bit about DPF but I have not noticed the light coming on to say it's doing a regen.
Yeh no what u mean about the run away engine thing some nasty videos on utube.
