The shop I took our AMG C32 to sent it to Burback's when they were unable to diagnose an audio issue in a short amount of time. After a few days, they told my original shop that they were ""100% certain"" the problem was the amplifier & that it needed to be replaced. Since Merc's price for a new amp was over $1,500.00 (!!!!!) I found a warranteed used one from a dismantler in Stockton, CA for $375.00. I replaced the amp myself & it did not resolve the problem. So... back to Goodyear on Andresen in Vancouver. They researched the issue & found that it was really the CD changer. Removed the changer, linked the fiber optics & BOOM! We have sound.
Burback's also told Goodyear that the supercharger was ""going out"" & that it would be $5,500-6,000.000, including labor to replace. They said it would render the entire engine useless if it went out & cost $20K to replace the engine. Goodyear dug into it & found that the problem was just with the bearing in the supercharger's clutch. Due to the price of a new clutch, back to the dismantler in Stockton. They had a complete, waranteed supercharger with about 50K miles on it for $775. Another problem misdiagnosed by a ""Mercedes specialist"" & resolved by Goodyear.
Guess where I'll take my Mercedes from now on.
