- ML500 W163 2003 Black LPG
Hi Everyone,
Just got a little Bluetooth OBD2 unit to try on my W163 ML500 (03). All works fine (within its capability) but it comes up repeatedly with this P4010 code. I do occasionally get a sluggishness from the engine under load, and now the little unit is attached and paired with my phone (Torque app), I get the error with sluggishness and sometimes not. I run LPG and normally notice no real difference with or without gas. To give an idea, on my last 5 mile run, the unit squauked up 4 times with the error but with no noticeable problem?
I am worried its to do with the Air pump and wondered how I or if can test it while stationary, or if it's important at all and could be blocked - the pump that it. OR if I'm worrying about nothing?
I can get it scanned with a pucker star unit, but not sure if its a transient fault.
Any ideas O knowledgeable ones?
