Not sure if this is the right place, but does anyone know the best (easiest) way of changing out the DPF sensor? For something that should be so simple Mercedes have put it in a terrrible position behing the air box with no room and play to access and remove the hoses. Do you have to remove pipework directly from DPF as I can see no other way and I can see removing the pipework will be a nightmare. I must be missing a trick i.e. an access panel? I would be most grateful if anyone has changed one out as it appears these do fail quite often.
