All,
Here is some feedback worth noting:

I would be very leery of attempting to refinish the valve seats on these ABC block solenoid valves. We do not know what the surface polishing specs are, or the surface hardness specs for them. It's quite possible the surface has now been compromised. Also, if you have left any grinding paste behind then that's going to be a problem as well. When I rebuild blocks one of the steps I take is to inspect the valve seats under magnification to observe any damage to the valve seat face. If they are damaged, indented, or have marks on the actual face of the these metal seals then I consider it trashed.
So far I have never found a valve seat that has been damaged, suggesting that any material trapped is always software than the valve seat material.
Recently, a few folks on the forums have been trying to repair their own blocks and asking me for help.
Also using the incorrect O-rings and not electrically testing the solenoids.
It's more reliable and less costly for you all, to send me your blocks for rebuilding before you have messed with them.
Hope this helps!
-Jim

Hi Jim,
I recently noticed some wet area in the shield under my valve block by the left front wheel...not bad yet but after two weeks and the front drops an inch or so...im at 62K miles..2005 S55...what do you charge to rebuild that front valve? and whats your turnaround time?...Im going to do some brake and coolant service soon, so maybe ill tackle this with you as well. need to see what to budget and what you recommend.
Thanks, Mike

I have a 2006 S65 and I know I need a left rear strut, but my right rear sags if left for a few days. Is it just one block or more? Are they easily accessable? What are you asking for a rebuild?

Rear wheels are controlled by one valve block at the rear.

Get under the car at left rear wheel and remove the squarish plastic cover near the fuel filter and you will see the pressure lines in and out of the rear valve block. A leak inside this can make either rear wheel sag.

How much do you charge for this rebuilt? How long does it take?

Hi,
The rebuild is $300 or $500 if you send both at the same time, plus $35 return shipping. Ivan get them turned around in a day if you need them that quick so I can often put them back in the mail that same evening on a last pickup.
