Hi,

I had some help from several peeps on this forum when trying to find the Yaw Rate sensor on my 2000 CLK 230k Convertible. If Uncle Benz hadn't pointed me in the right direction I may well have given up and resigned myself to a £600 bill from the MB garage. as it was I spent a couple of hours fiddling about with trim clips and nuts and bolts and fitted a 2nd hand part from Dronsfields for under £45. Happy bunny. Means I can sort out the handling problems on the Range Rover I've just bought. I know, what was I thinking?

Anyway, to return the favour, and just in case anyone else ever wants to find and change their own Yaw Rate sensor on a convertible CLK, here's how I did mine with a few pics to illustrate.

Open the boot and take out the boot floor panel.

Next remove the roller blind type cover which you pull across the boot space so that you can drop the roof. This was a bit fiddly but I ended up removing the bolts from above each end of the roller assembly (there's only one at the top of each but they are long), then removing the rails on each side, these are snap on with two screws at the back end and a couple of trim clip/studs in the tops of the runners (the trim clip/stud at the front end by the roller asembly is under some velcro - I have no idea why)

Once the roller cover is out that's the tricky part done.
Next remove the trim studs from around the bottom, sides and middle of the bulkhead. You don't need to take the top row out like i did (live and learn!) is it only me who finds these ****** trim clips finger tip killing painful to get out?
with the trim/felt off you will see a whole load of brass bolts. remove all of them from the lower panel of the bulkhead. If you lift up the upper piece of lining on the bulkhead you will see the top row of bolts which gives away that this is a two piece panel.

Once the panel is out the Yaw Rate sensor can be found on the left hand side of what must be the hydraulic system for the roof (?) and is bolted to the floor with two bolts just in front of another square brass/metal sensor which might be the acceleration sensor but don't take that as gospel.

Unclip the electrical connector by squeezing the sides, pop the new sensor in its place and put everything back.

Took me about 1.5 hours in total but most of that time was spent faffing about with the roller cover. certainly not a difficult job for DIY if I can do it and would probably be more like 30 mins for someone who knows what they are doing. Certainly not a 2 hour job as I was quoted at the MB garage.

I did read some messages elsewhere saying that once fitted you had to do some sort of initialising of the new unit (the MB specialist mentioned it too) but Uncle Benz assured me it was plug and play so I didn't worry about it. I've driven about 80 miles in it with the new sensor and it's been absolutely fine. No sudden braking on one wheel (phew) and no BAS ESP warning light. with luck that's one less thing to worry about.

As I said, thanks to all who've helped me with this, it has saved me about £550.00 by doing it myself.

Cheers all
