Thanks

Minh,
Were you able to find a Service Manual?

Yes, no paper manual per se. All of the service info is in the Workshop Information System as lkchris mentioned (startekinfo.com). I'm likely one of the few DIY dudes for repair and maintenance (not too interested in mods, rims and wraps.) Happy to help if I can, time permitting. NOT a trained mechanic, just a nerd that loves his Benzes and German tools.

Thanks lkchris and dlafever for the quick replies. I'm old school and prefer the paperback factory service manual, but if one doesn't exist then I'll have to buy some extra ink cartridges and paper and get to printing off the startekinfo website.

I'm in the market for an S350, but when I finally end up buying one, I'll be sure to check out your posts, dlafever, to check for any diy info.

I definitely appreciate your feedback.

I have some issues with my radio, the signal is weak and I think my radio antenna isn't working ( I'm searching how to replace it but couldn't find any info ). Tried the website you mentioned but didn't want to pay for something I'm not sure that will help... Or am I supposed to change the amplifier in the trunk ( I feel that's too much but I will probably search for a salvaged one if needed )
Thanks in advance!

Yousef, the startekinfo website is only available to USA residents. your country’s Mercedes importer (equivalent to our MBUSA) may provide WIS differently ... or not at all. USA law requires manufacturers provide service information to non dealer service firms and this is how that happens here

Search ebay for "mercedes WIS" you can get them for about $20

I have w221 s550 4matic. After I changed front air struts, the car started sagging on front right. Rear side is staying too high. Left front is good. I thought the problem is compressor is not sending air properly to pipes and changed air compressor with valve. Again same issue. I got the car to another mechanic. He told me the new air strut is broken. I’m not sure if it is the case but you guys have any idea what it could be?

seems Arnott struts quality control has gone AWOL in recent years - a number of users here have reported they failed straightway - and the indy garage I visited this year has also stopped using them...

However I can't stress enough - the level sensors, one on each front, and a well hidden single rear one (above the park brake module) does the rear of the car - these sensors link rods seize, bend out of position, or snap off and lie to the car about vehicle height. Maintenance / jacking up of the car / high vehicle loads / or allowing the wheels to hang on a two poster ramp, often exacerbates strange readings driven by seized link rods on their plastic ball joints - the car's brain NEVER goes out of its OEM ride heights (unless misreading of sensors, or from idiots trying to lower the car for cosmetic improvements
