Hmmm. It may be time to consider a real mechanic. The fact that they tested the alternator without using any equipment might be worrisome as well. Hopefully that doesn't mean they disconnected the battery from a running car. That wouldn't be good. Wouldn't be good at all.
At any rate, a trip to the dealer may be of some benefit. When mine was at my local dealer last summer, they ran the VIN and decided my voltage regulator should be changed. The voltage regulator never gave me any sign that it was bad. However, if Mercedes Benz says the history of 2002 regulators like mine indicate it could use an upgrade, and they want to do it for free, how can I refuse?
And yes, the â€śUber-Mechanicâ€ť (able to tell alternatorâ€™s good without any equipment) shouldâ€™ve been a dead give away. Then when he got out the pry barâ€¦Yikes!
â€ťI donâ€™t knowâ€”It must be stuck in here.â€ť
Yes, tie-downâ€™s tend to do thatâ€¦
So even though itâ€™s going to be pricey, going to dealership is sounding better & better. One phone call was all it took for one of their techâ€™s to come on the line and tell me how to re-set moonroof switch. According to him, it very well could be something remaining â€śonâ€ť when it shouldnâ€™t. Bring car in so they can take a look and heâ€™d â€śflash itâ€ť (whatever that means) & install latest software update from Mercedes.
Maybe Iâ€™ll be able to laugh about this later. You hear horror stories about â€śroadside rip-offsâ€ťâ€”just never thought Iâ€™d fall for one! 180 miles from homeâ€”shouldâ€™ve just driven on inâ€”but hindsightâ€™s always 20/20.
Any time power is removed systems have to be reset, and most of the time you can reset them yourself. Read your Operator's Manual for specifics, but I believe one way to reset things is to turn your steering wheel full left and hold it there for a few seconds and then turn it full right and hold. It might right and then left and I'm not sure it matters, but please read your manual under disconnecting your battery.

Another "fix" for this type of thing is to turn your steering wheel firm to the right and hold it for a few seconds and then firm to the right and hold. Try that if the other thing doesn't work... But check your Operator's Manual for the best information.
1st bring it to some one who knows how to change a battery . 2nd chack to c if ure alt is ok. more likely be ure seat module. c class are known for defective seat control modules causing current draws which causing ure battery to die.
