What causes fuel leak in Mercedes C270 CDI?
The first & most common problem is air being drawn into the low pressure lines – check for any signs of fuel leaks around the engine. Often no fuel will be visable but air can still be drawn in – check for signs of air in the low pressure lines from the filter to the fuel pumps & upto the rail.
Can you run out of fuel on a Mercedes?
If you are new to older Mercedes diesels and have not worked on them before, this is one of the first things you want to learn. Especially if you ever run out of fuel. Without knowing how to do this you will never get the engine started again! In severe cases just using the hand primer pump will not be enough.

Where is the bleed port on a C270 CDI?
C270 CDI `02 Hi all, The fuel line from the LP fuel pump to the HP fuel pump has a tee off which leads to a fitting bolted on top of the engine onto the fuel rail ( just mounted there, not connected to the rail. ) It looks like a plastic plunger or little lift pump or bleed port.

What to do if your diesel fuel line is bleeding air?
Here are the steps to take in bleeding air from a diesel fuel system: 1. Turn off fuel valve. 2. Clean outside of filter housing. 3. Install new filter element and new gaskets. A little oil on the gasket will aid a tight seal. 4. I’d suggest that you fill a spin-on filter with clean fuel before installation. 5.
Why does my Mercedes E270 lose so much power?
Most loss of power issues on diesels is due to fuel starvation caused by a dirty filter. You say it heavy on fuel, diesel knock all the time and low power at low RPMs. You may have an injector problem. Is the car smoking under normal acceleration?
Why is there no air in the fuel pump?
Often no fuel will be visable but air can still be drawn in – check for signs of air in the low pressure lines from the filter to the fuel pumps & upto the rail. If air is present then I would replace the O rings at the end of the low pressure lines. The fuel filter can also cause problems if it is not a genuine filter.
What are the common problems with Mercedes diesels?
Here are some common problems that affect many Mercedes-Benz diesel models including E350, ML350, GL350, R350, Sprinter, R320 CDI and BlueTec models. Common problems Diesel Particulate Filter. As Mercedes DPF traps and holds soot, with time it reaches a point when it needs to be ‘emptied out’. This is done by regeneration.
Is there a problem with the Mercedes Benz fuel pump?
New fuel system O rings all round, no fuel leaks, no air visible in any fuel lines. Reconditioned high pressure fuel pump, made no difference. Injectors tested for bypass leak-off…all OK. The only time it behaved normally was during the leak-off test when the return line from the injectors was blocked off.
Why does my Mercedes Benz Fuel pressure keep going up?
Mine acted up when a partial blocked filter (only about 1000m – must have been a dodgy batch of fuel) caused air to suck in. Could be doing that – and the air ending up – anywhere in the system. Right as rain ever since popping the new filter in. New filter in, no change. Pants!
