my S550 is having AC problems, its blowing warm air, brought it to the dealer 2 times

1st time, they said they find a leak and fixed it, and find out the aux fan is not working correctly, they change the fan switch then ask me to go pickup the car, ok when the valet give me my key, im pissed, still blowing hot air, i can't imagine they don't even quality control the whole service, my advisor ask me to bring the car back in monday since that was a fri

ok 2nd visit, they took my car in for 4 days and told me they found out the expansion valve is not working rite, replaced it and told me everything is ok on thurday, so i went to pickup the car

so now, one week after, same problem came up again, blowing warm air in the nice CA afternoon over 90F

i think i gonna bring it to another dealer tomorrow, Penske sux

 

Mention:

DTB P-B-83.00/109d request they utilize EDAC (MBUSA enhanced diagnostic assistance center) to diagnose.

P-B-83.55/101a the compressor may be contacting the upper section of the oil pan this will result in no refrigerant being delivered resolved by installing shims at all three contact points.

 

thats crazy. talk to the service manager, or the DM. also the other dealer wont be able to do anything because the first dealer has already been paid for the warranty work. the only way around it is if U call the Service District Mgr and complain about the dealership. good luck...

 

tomorrow will be the 3rd day at the other dealership, my advisor was telling me that a collapsed hose was found, and that will be replaced, dunno if that will cure the problem or not

and thanks konigstiger

i will mention those DTB to the advisor tomorrow also
