Unable to get rid of the P0101 code myself even after fitting a new MAF and clearing the codes, I took it to an indie garage. They had the Mercedes Star system and said that new MAF sensors need to be “adapted” to the car using Star. So they did the ‘adaption’ for my new MAF sensor and the P0101 code could then be cleared!!
That just left the P2463 soot code and they were reading the DPF at 380% full. They said they forced a regen but that it wasn’t successful in reducing it much and said I may need to have a new DPF or to get it cleaned out manually. However, when I went to get the car the next day, they said they had just done a software update for their diagnostics system and tried a regen again and this time it was able to get the DPF down to 130% full, but no lower. I collected it and after a bit of driving the car started doing a regen by itself, so I headed out onto the motorway for an hour and the soot content went down to 34%!
My jubilation was short lived however as on the way home, engine light back on and back into limp mode. Just one error code this time which was P2279 “A leak was detected in the intake air system”. So I’m thinking a) there probably is a leak and this may have been the route cause of my P0101 error, which meant no regens which lead to the DPF blocking and hence the soot error and b) if there is a leak, my MAF ‘adaption’ was done with a 380% full DFP and intake leak, which means the car may not have learnt the right values.
So this weekend is going to be spent looking for an inlet leak...
