Hi.
I own C220 CDI Estate, 2005 reg with 68k miles on clock.Bought last week and I have to say it drives superb (my previous cars was Honda - great too ). Today I started having first troubles with my Merc. At speed 80mph on motorway I could press the accelerator to the floor and nothing happened, had to stay in crawler lane for the rest of the journey as wasn't able to overtake At the way back to home I was going up hill at speed 20mph and wasn't able to accelerate again - very frustrating when you own a 150 power horse machine
I couldn't rev the engine more than 30 on the clock, doesn't matter I used auto or manual mode.
The engine light comes up on clock so I went to my mechanic which I know for a years. He did computer check and came to me with some numbers/fault codes. He explained me some of them but I wonder can anyone tell me what the numbers stand for .I will write his explanation too so please tell me if they correct or not. Here they are:
-2043 - Camshaft Sensor - No signal
-2509 - Heater booster - No signal
-2045 - Crankshaft Sensor - No signal
-2356 - CDI Control Modul Recovery - Error
-2521-
-2359-
-2626- Diesel particulate filter full
-0105-
Would be grateful if someone could explain that to me.I own this Merc for a week, soon going on holiday with my family to Europe so must get the car in good shape
Thanks.

 

Hi again.
Not sure that anyone read my post ...Never mind
Anyway, had the computer checked again and the only one code came on - 2626. Mechanic says it must be Diesel Particular Filter. Went to some local GSF parts seller and they told me ...500£, almost hit the ceiling
I will have this replaced tomorrow as I bought the car from dealer under 3 months warranty so he agreed to pay for it.
Will post the result here if it will help my Merc to run smoothly again.

 

Had the Particular Diesel Filter replaced. Drove perfectly only 25 miles and the engine light come on again, and of course loss of power.
Called another mechanic and he found that one of the pipe from turbo was teared. My mechanic put some duck tape around it and it works !!!
Will have to buy new pipe as it will not last long and I am before my journey to Europe.
All the best

 

You are unlucky with the diesel particulate filter (DPF), I understand that some MB cars built before 2008 had them and others did not, its just a lottery. I hope you kept the old DPF as it is possible to cut it open, remove the junk and reweld it together so the filter will NEVER get blocked again. Thanks for the heads up about your problem, luckily my 2006 CD220 does not have a DPF but no worries, it still does crap fuel economy. GJS

 

Hi I have a c220 cdi and it won't start, it says the fuel pressure control valve open circuit, so I changed it and it still won't start.......Any ideas anyone?
