E320cdi
This is my first post and this is my first MB. It’s an E320cdi face lift on a 57 plate and I have had it for 6 months (I have to say its awesome)
It has done 115,000miles and came with a full main dealer service history.
Unfortunately it has started to suffer with the (common from reading this forum) occasional intermittent problem of jumpy acceleration followed by limp home mode. (Stopping/ taking the key out and immediately putting it back in completely cures it) there are no warning lights on the dash.
I had it hooked up to star at an Indy and the fault codes seemed to confirm this (They did try replacing a sensor which made no difference)
I have read lots of post about it saying it’s not a fault with the turbo itself but the actuator electronics, however, as they come as one part (turbo and actuator) the only cure is a complete new turbo.
However there are people who rebuild the actuator electronics (rebuild your own for £70)-

Has any one tried this and does anyone know the success rate?

MBs naughty little secret…

Well I had the actuator changed at the recommended above in Leister.

Its £75 for a reconditioned part if you send in the old one, or drive in and they swap for a reconditioned one all in £150.

Apparently it’s the mother board that wears out in the actuator which is an exchangeable part and easily done.

It took 30 mins to have done and….. 100% fixed :)

The car is transformed with lots more power (especially low down torque) Iv saved enough to have a terra-clean and maybe a remap - any recommendations on the best for this engine?


I have heard lots of main dealers/ specialist indies use this service and I cannot wonder how many people have been charged for a full new turbo (£1600 I was quoted) and just got a reconditioned actuator that cost the main dealer £75?


I cannot thank t-dawg1 enough – saved me well over 1K :) Top man
