Hi, thank you for the response, I have had this problem for a quite while, I did the obvious and replaced the fuel lines, (I fixed an unrelated problem with new Glow plugs and a Glow Plug Relay) Then one day it stopped cold, NRMA Towed it home, I put it into a Burwood Workshop and they unleashed someone who had no idea what he was doing and destroyed the engine cover and three injectors, he replaced the injectors and cover but could not make it run, I removed my car from his workshop. They Charged me Nothing but had the Van 2 Months.
I then took it to a Diesel Specialist in Carlton, (notice I am not mentioning names) They again replaced the injectors with reconditioned units saying the units in the Van were leaking, They got me on the road for a short time, Cost...$2500.00, A week later It went into limp home mode again so I went back to them, They put it on the Computer and they said the Vans' Computer was faulty and required repair, Estimate cost $2500.00 at that stage I exited their workshop firm in the knowledge they had no idea either.
I Decided to bite the bullet and go to a Mercedes commercial workshop. They got it running (without repairing or replacing the computer) after blocking the Vacuum hose to the headlight adjusters and Fresh Air Vent actuator line, this seemed to cure the problem They said I had low pressure on the Brake Booster Line, This apparently has a sensor that will cause this fault, It was OK for a while (2 weeks) but they only replaced one problem with another, for the Princely sum of $700.00 I had an engine that worked but I gained Headlights that point to the ground and no fresh air in the cabin, I elected not to have this fault rectified as I was not sure they had found the fault, I decided if I were able to drive it for 2 months without problem then I would consider the problem found and allow the expensive Vacuum line repair to be carried out. Thank You Mercedes, This of course counted for nothing when this week the problem returned, Back Into limp home Mode with the EDC and Glow Plug Lights Illuminated just to P%$#s me off.
I have taken it back to Mercedes, I will be the customer from Hell soon if They keep the rip off that is in progress going. It seems even the Mercedes Mechanics (who you would expect to be able to quickly diagnose the older vans from experience) are capable of taking 5 hours to fault find a (Simple) Vacuum Pressure fault @ $150.00 an hour, they charge an hour what I get paid a day and think I should be happy with their product, Wrong!
I really must say if you have to depend on your van to make a living Don't Buy Mercedes, if you do not take this advice then buy a new one and sell it as soon as the warranty runs out or not later than 5 years, the decline is rapid from that point on.
I want to know (Really) why a computer, mind you after 100 years of Mercedes building Cars and Vans, Why can a computer tell me I should be driving with less than half power (very dangerous situation on Australian Country Roads) simply because there is a low pressure fault somewhere or some sensor has flipped its lid. None of these faults will cause damage to an engine! Now I don't mind warning lights doing their job, Most people will respond by having the fault repaired but to have No Power? it should be illegal to do this. (Government, Get Involved before people start dying) How did we ever get around before computers, Now if I could take a Mercedes Vito Body and Motor, surround it with Japanese Electronics and p&^%s of the German Designed Crap then you would have A Van. Another thing that amuses me, there is no Fault Tree published anywhere that you can run down to quickly locate the area of a fault. Damn, too easy you say? We Germans have a Computer for that! who needs a Schematic, Its a Mercedes, Built to last.....10 years. I know I am not the customer Mercedes wants so Me and others that drive their older vehicles are the bottom feeders of the Mercedes Retail Tree but someone like Top Gear may take an Interest in The Longevity of Mercedes Product and Give them the Serve the Deserve. Does anyone know an Honest (prefer a mobile mechanic now) Mercedes Mechanic that actually knows what he is doing in Sydney's West?
