Hi Stan I have an s320cdi , 118k miles. Ican hear a rumbling from below as if the exhaust is knocking and the car will make a whooshing noise. Its been in to Mercedes but they could nt find any faults. I thought it would be a blocked dpf because this was found on the codes about a year a ago when it kept going into limp mode- I have found the car will only run - just- on Shell nitro diesel
The car will run rough if I put normal diesel in and often will go into limp mode
I will check the pressure with my hand, if there is no pulsating what do you suggest?
