If you can regenerate your filter and its not too clogged then I wold leave it but if the professionals say it clogged its all you can do to have it removed. Will at p torque is a nice guy give him a call
flip me this is soooooooo bad, I do feel your pain I was still looking at the crankcase sensor but with no codes showing where do we go ?????. I was waiting until the weather changes but after the fight I had with the sidelights I have lost the love.....who puts a water bottle right in between the fog light housing :-/ seriously bmw sort yourselves out :-(
I'm at the "the injectors are the prime suspects" stage too. I've got an oil and fuel filter service in about 8000km and I've already been on the horn with the dealership about the weak power problem.
They said they can analyse the fuel to air ratio and make sure it's within trim values. Could be that the timing needs readjustment and/or the injectors are fouled preventing the proper quantity of fuel entering the cylinder. That would manifest as a loss of power/flat spot/hesitation I would think.
I've tried a bottle of injector cleaner in the gas tank, but it didn't really do anything so I'm going to have the dealer hook it up to their computer and see what comes out.
Don't know when the appointment will be but probably around end March/early April. I'll have them change out the winter tires at the same time.
On the peugeot forums a couple of guys have had success by removing the intercooler and draining the oil and flushing it with degreaser. I think it's a bit of a job to get the intercooler out, however.
Did they look at the turbo vacuum solenoid that controls the variable vane geometry? I think the solenoid is down under the fuel filter somewhere around the EGR if I'm not mistaken.
Maybe oxygen sensor?
I mean loss of power on a diesel is due to one of two things: (1.) poor Airflow or (2.) poor fuel flow.
Reading round it it could also be a egr issue being around 1700-2000rpm
I have ordered a stainless steel blanking plate
But as these are euro4/5 it will need a few small holes drilling to allow just enough air through to satisfy the sensors this seems a common route and fiat even sell a egr restrictor through their parts departments
Fingers crossed this £5 trick works
If not ill send all injectors for a ultrasonic clean
Discovered from the service records that it has been 56,000km since my fuel filter was changed. Wondering if this isn't causing some of my issues?
Notice too that my fuel efficiency is declining. Used to get about 5.2L/100km in winter (with winter tyres and heating on all the time). Now I'm up to 6.7L/100km which is getting stupid. Quoted should be around 4.7L/100km.
Anyone ever change their own fuel filter on the Cooper D? Easy? Hard?
just to throw another spanner in the works I have put some dpf cleaner in and turned my tuning box up which feels like its boosting earlier in the power range which has taken abit of the flat spot out.....and is not as noticeable just now:-/.....so am now starting to think its a mapping issue AGAI, but not sure I just wish BMW would come up with a solution! !!!!!!!!!!!!
