seat belt pretensioner faults

[ml320cdi]

I have these DTC showing for both side seat bets ( 10 faults each side )
does it point to a control module failure?
I have no lights on in the dash but the car doesn't go above 3k rpm when driving. I tried cleaning the wire connections coming from the seat belt buckle but it didnt make a difference. If I disconnect one of the connections, the fault becomes ( permanent ) which is expected I guess but re-conencting it just gives the intermittent message again.

Hi there. I realise that it has been some time since you posted the above post, but I am currently going through the same issues. I recently bought my 2008 ML320 CDI 10 edition and the SRS remains on all the time. The codes I am getting are the same as youhave mentioned above.
Can you confirm that you managed to sort the above issues you have mentioned and what did you do to achieve it?

I also put a new tyre on the left rear the other day, which caused the check tyre pressure light to come on and a short time after that the ABS /ESP lights have also come on and can't get them cleared.
When doing the diagnostics last night, I think the ABS/ESP light relates to the speed sensor on the rear left (new tyre!!!)

I'm new to this sight and would be very grateful of any help/direction.
