Engine & cooling
After a long trip with the 2010 Mercedes GL350 bluetec, I noticed fresh oil on the garage floor. I took the GL350 to a local mechanic for an oil change the day after, and the mechanic noted that there is significant oil under the engine. Few days after, check engine light came on, and I took the GL350 in for a check, and another mechanic confirmed that the engine oil cooler seal is broken causing the oil leak. It seems that this is a very common fault with Mercedes om642 engine in my GL350.

Fuel & propulsion system
About a week ago I bought diesel fuel from a truck stop in long beach, not my usual purchase from my local gas station. One week later I get a message to change my fuel filter and got a trouble code indicating a low fuel rail pressure. I had the filter changed and experienced hard starting later on. The old filter had water and some algae contamination which is very common in diesel engines. I suspected water from the truck stop where I got fuel from and tried to remove it using a diesel additive, sea foam. Starting my car got worse to the point where it would no longer start. I called a tow truck to take it to the dealer where I bought the car from and they claim I bought bad fuel and the additive ruined the entire system. …
After extensive reviews of tdi forums, common rail forums, diesel forums I have found a commonality in the failures in the high pressure fuel pump (hpfp). Mainly those failures were attributed to metal shavings/particles/rust found in diesel fuel systems. The fuel level sending units are usually rusted in each case and most likely is the source of metal/rust contamination and ultimately cause of the hpfp failure. Failure of the hpfp causes the cr to lose pressure therefore the injectors are starved of fuel or worse clogged with rusted metal particles. This sudden loss of fuel causes the engine to shut down instantly along with power steering and power brakes. Depending on the reserve vacuum volume in the booster, consumers May or May not have enough vacuum to adequately bring the vehicle to a safe stop. …
