Hi Guys,
I have a 2012 2.2 140 sport and I'm having trouble with it running rough and being noisy, diesel knock I'm thinking. I was told by a so called specialist that someone had removed the DPF and done a re-map and it had been over fuelling and now it's got a cracked piston, so it's a new engine job. Couldn't pay for that so stripped it myself as I used to work as a mechanic many years ago. The only crack I could find is the one in my big fat arse.
Rebuilt it with new pistons, oil pump and gaskets. Chain had already been done. Had the injectors tested and apparently they were quite bad so fitted a new set. In hindsight I should've done that first but there you go. Put a DPF on as you could see where the old one had been welded up so would probably fail the MOT. Fitted a new fuel filter as the old one was black and full of sediment. Got told it was probably diesel bug. Took it to an injection specialist who put it back on the standard 140 map and set it to learn the injectors but left the EGR deleted.
When I picked it up it was running better but not fully ok and it was still quite noisy. The guy said it sounds like a piece of the sound deadening has dropped off so take a look. Nothing wrong there. Ran it for a couple of weeks then got a red info light and "Engine Malfunction" message. The following day that had gone and two days later the orange engine light came on. The traction control light is permanently on, as is the "Service oil now" message. The brake warning light comes on for a few days then goes off for a few days, and It's lost the hill start assist.
After watching loads of videos on YouTube over the weekend I took the wire off the MAF while it was running and had no change. So I've just fitted a new MAF and it's not made the slightest bit of difference, carries on running when I pull the wire off and the light's still on.
I've lost confidence in going to local garages as they all seem more interested in bending me over and shafting me on price instead taking an interest in actually fixing the real problem. I don't think they're listening to me when I tell them about it.
Is there anyone in the North Wales, Deeside area that can genuinly help and knows what they're doing before I put a match to it.
