It's only done 50k miles...

And it's been plugged in more times than I care to remember over the last 2-3 weeks...!!
I didn't try this reset procedure yet, going out in about 45 minutes, will have a try then...
So, carry the scanner with you and immediately read the codes in the ETC when the problem occurs.

Not sure if it checks the transmission as I've only ever taken any notice of the fault codes that do show...!!
However, seeing as this happens at pretty much every speed bump, it wont be that hard to check next time...
Weird really as it doesn't really happen when slowing down to a stop, for lights etc...

Merc version is really quite **** by comparison...

I had Carly for my X5, it was very good, you could get right into the bones of the vehicle and do a bit of coding etc, along with error code checking and clearing...
For the Mercedes, Carly is rubbish basically, only talks to half or so of the ECUs and there's zero coding or anything else for that matter...!!

So I'll make sure I know what's what before I hook it up...
I've actually done the reset procedure this lunchtime and it actually seems a lot better...
I've only done about 5km around town tho, I'll find out for sure when I get to a speed bump if it's actually made any difference...!!

My problem still there, seems only valve body replacement will give something
