Question about 1997 Mercedes-Benz C-Class
Car sometimes will not start but after waiting ten min it then starts then it just quit starting

Crank shaft position sensor is bad. This is the most common failure. Its location is on the rear drivers side of engine, where the transmission bell housing mates to the engine, only one small bolt and a two prong electrical connector hold it on. Usually will not throw a trouble code. If you remove it you can test it with an ohm meter, will have an erratic reading or read open loop, can malfunction intermittently or permanently after parking vehicle and won't restart. Applying some heat source to it during ohm testing with a hot air heat gun will usually cause the sensor to read open loop if your not sure if its bad or not. This reply is probably way to late, but I just happened to come accross it while online. Harry (master certified MBZ diagnostic tech)

The dealer near me charges $365 for a 4-cyl, $395 for a 6/8 cyl, or $425 for a 12-cyl. The only actual repair/maintenance you get for that price is an oil change (with Mobil1 and the MB filter, which are CRITICAL, ~$120 on its own) and tire rotation. This makes a lot of people think it's a scam, but really, it's a little steep, but definitely worth doing. The rest of the service consists of a massive inspection of your vehicle covering the following items.
-- Fluid levels
-- Tire tread/pressure/wheel condition
-- Air filter (inc. clean out housing)
-- Cabin air filter (inc. clean out housing)
-- Lubricate sunroof rails, locks, hinges, and seals on body.
-- Drive belt and tensioner
-- HVAC system operation
-- Instruments, cruise control
-- Windows/sunroof operation
-- Transmission fluid
-- Driveshaft, inc. flex discs
-- Road test
-- Reset maintenance light
This is actually pretty essential to do, despite seeming like a lot of money for not much work. I have very rarely done one without catching a few things that the customer needs, and often it was a problem that would have gotten far worse had it been left to its own.

Have the same issue with mine (same year and model). I've had the car for a couple years, and I regret buying it every time I get in it! Has your sunroof broken yet? It will... common problem, and a pain in the @$$ to fix yourself (major pain in the wallet to have someone else do it).
I will be opening up the steering wheel to get to the buttons and try to fix them, as soon as I can get a short enough screw-driver (hopefully it's a fairly common size, because it's impossible to look into the hole to see exactly what should be used.
DITCH THE CAR A.S.A.P.
