P0101 MAF and P2463 DPF soot problems...

[HITECH]

You probably find the DPF was not the Problem at all. Normal procedure with a DPF problem would be to replace the DPF sensor 1st n foremost then if fault is the same replace DPF. But almost definitely replace the sensor if the DPF is getting replaced.

I replaced also dpf pressure sensor and code p2463 still pending and engine light on... car drive much better i can feel it but max revs are only 3000, i have done also reset adaptation, but not help

Hi,

I, like many others, having similar issues. I changed out the pressure sensor, but the DPF shows 400% still.. I then read you have to force a regen, but there seems to be mixed info on here if you need Star or can use a consumer scanner. I have the Icarsoft MB v2.0, but the Service menu doesn't have dpf regen for the W204 automatic sedan.. (unless another model works the same?).

I saw you said you reset the 'adaptions'.. im not sure what that means, but I wondered how you do it as I could try..

Thanks!

the icarsoft mb2 v2 has the dpf section , where it scans the dpf system and adapts new values when you change sensors etc. without it a forced regen probably wont occur. the best chance you have is to delete error codes for dpf and drive in 5th gear at 2500 rpm and say a prayer for 40 minutes. fill up with premium fuel and add a full bottle of double concentrate dpf cleaner from halfords £8 . before setting off .

The diagnostic said a regen won't be automatic with a 400% fill, but I can try...

I did notice it said 23g soot, and less than 1g ash.. so not sure if that is good or bad..

But are you saying the icarsoft can't do a forced regen? (For 2009 C220 W204 auto). Seemed to be mixed opinions about needing a Star or not..

Thanks for responding!

ive just done my own car this weekend after going into limp mode , i was 386 % fill level . i replaced the sensor at dpf and tried 3 times with mb2 v2 to do a driving regen and it failed 3 times , saying timed out . i ended up just doing an adaptation and low and behold the car revved past 3000 rpm , fill level went down to 8% with pressure readin 0.01 bar . could be you just need mb2 v2 to talk to the ecu ...... ps , by all accounts you MUST delete error codes otherwide dpf just wont respond to a regen even with a new sensor fitted.

Sorry... im new to the icarsoft... i still don't really understand what you mean about "do an adaptation".... does that mean clear the fault codes? Or something else in the menus I haven't seen... (sorry if its staring me into the face!)

The MBv2 doesn't list my model for a regen or dpf calibration test.. it lists lots of C220s, just not specifically mine...

So with the MBv2
1. Clear the codes (so engine light off)
2. Ignore the dfp fill level after that
2a. the adaptation thing?
3 go for a 40min burn up the motorway =>2500rpm (with dpf cleaner)

?
I don't mean to keep asking dumb questions! Haha

The mb2 doesnt cover dpf. You need the mb2 version 2.

Yes.. I have MB V2.0 not an MBII..

This is what i have...

Ok. Try the dpf menu in servicing. Say no to oil in dpf and let it do its thing . It gives you a report saying something like level is below 250 so a regeneration is possible. Unplug the scanner from the top . Switch off engine and ign and wait. Start the car and see if it revs over 3000 rpm. If not reconnect scanner and run test again. Make sure dpf codes are deleted . I also deleted them via obd2 menu. I did take a lengthy drive at 2500 rpms with it in limp mode . Stopping every now and again to delete error codes. I do think the initial test reset my values though then telling the ecu everything is fine. Attached pic is my final result.

I really appreciate the help, and I will try the drive and reset method. It may be i didn’t give it time to work out I changed the sensor to assess the new pressure levels.

What I'm saying is the when you go to servicing, DPF select C(204)... the W204 C220 4Matic Bluefficiency model isn't an option... there are other C220 CDI, but not the auto Blueefficiency... i think that's partly the issue lol.

Some say 1st gear around an industrial estate works. ?? I'd pick any with the same engine tbh. The drive train isnt really part of it. .. you really need to do the 1st part it counts down 3 minutes then gives you a report. That's the part that worked for me. I dont even think my car did a regeneration because the mileage at the last recorded regeneration was 500 miles ago. You'll know something has worked if it revs beyond 3k.

I'll give it all a go.. thanks once again.

Earlier I plugged it in, chose any 220 CDI, skipped past the oil in dpf option, but said it couldn't communicate to do the 19min test. It did also say that at 400% fill, a regen needed to be forced and isn't automatic, hence my reluctance to scream around in 1st lol However, the engine light was on, I didn't clear the code first... so may be my mistake..

It's certainly an ongoing project!

 

[OneForTheRoad]

Yes you Must clear the codes 1st. It wont work otherwise.

Just remembered I updated my icarsoft to version 11.40 . They updated the database. So your car version is maybe on there now..

Yeah, i checked earlier the same and is not in there still :/ maybe the 2009 model was too tricksie to figure out the programming lol

I'm crossing my fingers it has 'communication error' because I didn't clear the fault codes first... Will try again tomorrow.

Maybe the dpf really is 400% full...

p101 is from MAF Sensor problem
and That Maf sensor does not work plopery
than your car DPF doen't work
same as my car
so just replace the MAF Sensor
