I have a 06 SL500 has 38.000 miles on it. The left front was sagging after sitting for 3 days. I had my local MB mechanic flush the ABC system and replace the filter. All struts and hoses look good with no leaks, now it sags after 12 hours. Is my only option to replace the block valve at $2500-$3000?
I appreciate any input.

You wasted your money on a flush, see someone other than the piggly wiggly cart girl who has the diagnostics to quickly tell what is at fault

He scanned and advised me the problem is with the block valve. He said the flush may help the problem, or make it worse. I understand MB does not have a rebuilt program. Are you aware if their is a rebuild option or new OE the only way to go?

I have the same problem with my 06 SL500. The rear driver side is sagging after the car is turned off. Looking for some that would help me fix the problem. any recommended shop near lake elsinore, corona or IE area?

I have posted DIY on resealing these. Also at www.DIYBenzRepair.com Save yourself time and just change the seals. To be fair, the flush needs to be done either way. Rarely the flush itself helps the problem but typically need to change the o-rings and clean all the gunk out
