Back in early December I posted the following:
"mbtech208. Normally I flush my brake systems with a pressure bleeder at 20 psi. I drain the reservoir, refill it with new fluid and bleed about 8 ounces per caliper. My question regards cars with ESP, such as my 1999 E430. Is my current procedure sufficient? I have an M/B Maintenance Manual covering cars since 1994, and I noticed that some cars have a bleed valve on the ASR/ABS unit. I can find no such valves on the E430. Unfortunately, the manual does not cover the W210 cars. Any guidance on the correct procedure for this car will be appreciated. Thanks."
I know that mbtech208 tried to post a reply, several times in fact. However, the post never actually appeared. Apparently several members were having the same posting problem in that time period. Could mbtech208 please repost his reply? Thanks again!

The way to flush the system on ESP cars is the same as non-ESP cars. First remove the reservoir and clean it all out, then reinstall it, fill it with clean fluid, and hook a pressure bleeder up to it. Then start with the right rear wheel, crack open the bleeder screw on the caliper and flush the line out. Next go to the left rear wheel, then right front, then left front.

Thanks, Dave! The next big question in this regard will be the new sensotronic brakes. I wouldn't want that control unit to get corroded or fouled! Thanks again for your help!
