See if massage is working. If not, could be pneumatic pump. I recently had mine replaced under 3rd party extended warranty and it was about $1,300.

Since being paid directly by 3rd party warranty, I noticed there was a reminder on the invoice not to discount labor. I was just billed the deductible.

As far as I remember (please correct me if I’m wrong - there are so many super knowledgeable and helpful people here), you have to remove the silver trunk skid plate, pull back the trunk lining on the left hand drivers side to expose the pump. Few torx screws and 2 plugs.

Hey, if you don’t mind me asking, which 3rd party warranty are you using? My CPO warranty just expired a few months ago and with in weeks, my pump fails. Thanks in advance.

Sorry couldn’t give you an easy solution. It seems that there are no easy solutions with the W222. Too many electronic components and ECUs. If you want to save money, you could always try to find a rebuilt or used pump online. I watched my Mechanic replace mine. It looked pretty straight forward. Basically a direct replacement plug and play situation.

Long answer, but Fidelity Platinum. They have other levels of coverage as well. I was told the Fidelity warranty can be purchased from any dealer with relationship with the company, not just MB dealers.

Mine is a special situation. In April I bought a 15 S550 from an elderly friend/client that due to health issues only had 6,200 miles on it, but was placed in service in Sept 2014 so out of warranty. The two dealers whose warranties are most often mentioned on this site suggested Fidelity Platinum. This warranty covers everything, except...., mainly just maintenance items. I have other vehicles so I expect to drive the S550 6,000-8,000 miles per year. I negotiated at a local MB dealer an 8 yr/80,000 mile warranty with $250 deductible for 4k, which was an easy decision for me. Warranty pricing seems to be based on vehicle mileage when warranty purchased.

Thanks, I’ll give them a try.

Reference bulletins LI91.25-P-065343, LI91.25-P-058219, and LI91.25-P-059380. Normally bulletins are only covered under warranty however, if 065343 and/or 058219 are found to be the cause argue for MBUSA goodwill assistance for diagnostics/update since update corrects malfunctioning software installed at production. 059380 may not qualify for assistance, note MBUSA should favorably consider assistance if vehicle was purchased and serviced through MB dealership.

Brought Tilda (MY 15 S550) over to Europeon Auto Tech where they ran an SDS (Star Diagnostic Scanner). I'll be bringing Tilda back for more tests to get to the root of the problem before replacing the pneumatic pump(?) Tilda has only 22,xxx miles and this seems to be one of the weak links of these cars after seeing many other's having similar issues. A friend had similar issues with both his W220 & W221's so you think MB would have figured this out by now.
