I do apologise if this has already been discussed but I couldn’t find the answer.
Just recently bought a GL320 cdi 2007 with 150k on the clock. Have sorted small oil leaks from intercooler pipe to muffler o ring, breather and turbo intake. But can not figure out what is wrong with egr or other components in that line.
Symptoms-on acceleration it starts to jerk if accelerated at certain rpm. If accelerated slowly it is all good and also if accelerated hardly but somewhere on the middle it starts to jerk/hesitate especially when there is a load (going uphill from traffic lights). Scanned with star and no faults-tried egr actuation and engine starts to hesitate and even can stall if cold when i actuate egr to open position. Egr replaced with other used one and still same symptoms/behaviour. When done egr self test-star showed that egr needs replacement,hence swapped it to other. When egr actuated open-engine struggles and white smoke is coming of exhaust if accelerated briefly (also struggling to rise rpm)
Also the MAS readings were very low when checked it today.
Any clues please?
Swirl flaps…dpf?
Thank you in advance
