Hi John,
Thank you so much for this information. My good friend actually passed this car on me for nearly nothing as he got brand new MERC. If I bought them from the Garage then yes I would send it back for sure. Do I have to worry about the management light when I take it to the motorway to try and regenerate the DPF? Do you think the management light will switch off itself after the soot is burned? I am very new to all this things so I'm a bit worried if I will do more harm to the engine itself.
Thank You
Patrick
