One other thing. It tries to fire up when I mist the air intake filter with easy start, though it doesn't catch.

Thanks for your reply I put in 40L of disel and the instrument panel shows the correct level. I also did the test sequence on the instrument panel which shows the individual levels on both sides of the tank and this confirms that the fuel I added got equally distributed to both sides.

Hi I'm new here...this is my first post. My 2004 L322 RR TD6 won't start despite healthy cranking. I let the fuel run low to the 40 miles range message. Then it fails to start and gives the "FUEL INJECT. SYSTEM" message. I've refilled the tank at home to over half full but still no start...
