Not familiar with your car, so I can't provide specifics. But maybe there is some useful info in my write up for removing the ETA's in my S600.

The basics are probably similar. Your signature states you like to DIY, good for you. If that's true, I would recommend you buy a subscription to Alldatadiy.com. Lots of great info, instructions, test procedures, etc. I have found it very valuable. Some will say it's not that great, but I've found it's more a matter of knowing how to find what you're looking for. If you do decide to sign up, can I ask that you use the link on my webpage? Thanks. and good luck.
