E320 (2004) loss of power on take off

[kerryhastingsspital]

Have been a private owner of E Class Estates for over 25 years now ~ all automatics. Now have a new problem: when starting in the mornings, my E320 is very sluggish; it moves through the gears much too quickly, so that it is already in top when tackling the slight incline just 200 yards away from home. Occasionally same symptoms occur during/after a long motorway run at even speeds. Problem can often be resolved by stopping; turning off; waiting few seconds and then re-starting. Any ideas what this is likely to be???

Could be one of a few things but the fact that it clears after a restart implies its in safe mode. Hence it will have logged a fault which your local mb specialist can read. Probably the maf but best check the codes before spending any money

It needs to go onto star to check the fault codes but I too think it could be the MAF.

Probably the MAF?

So before spending a lot of money try inspecting it and cleaning it with contact cleaner spray or even brake cleaner spray (RAC-man tip). It unclips and unplugs from the air inlet pipes. Do not poke solid things into it.

Many thanks ~ this sounds (to my inexperienced ear) like good advice.
