sounds like the cat might be breaking up this is very common on this engine

i will try and explain it. the engine constantly monitors and measures lots of data from various sensor on the engine the control module then interprets the data and adapts the fueling of the engine as necessary. so if you have a poor air mass the engine control module will adapt to run poorly...

when you change the air mass it is worth getting the adaption data reset as this will make a huge difference to the car. But it will need to go on a star (or good equivelant) to do this

i dont think you will be able to clean it as i think it is an electrical fault with it. Yes they are under the plastic engine cover at the back

for sure. i did an ML320 today with the same fault as you are describing (misfire under hard accleration then when turned off and started misfire has gone) and it had stored faults with misfire on several cylinders.

i reckon that you have a fault with the air mass sensor i have seen this several times on the V engines but it definatley worth getting it on a star.

if your timing is that far out and you have no compression it would have done a lot of damage. You are going to have to take off the cylinder head for further investigations.

if your ML has a sunroof the drain tubes run down both the passenger and drivers side footwells i have seen these where they have come off. would be worth a quick check.

when you push the switch with the engine running it should put on the traction warning triangle. if this is not happening then there could be a fault with the switch.

i would guess that the dealer has had the car sitting for a while i would take it back and get them to reset the days since registration this should put it right

not stepping on alfies toes but if you dont want the trip to woking we are in poole and can do the job for you

i would be careful if you change the oil and filter on this box yourself as the 7g tronic box has to be refilled via the sump plug and you need to get the correct gearbox temp to set the oil. the 7g box has had many faults since they were brought out and mercs have had several service measures...
