I own a 1998 Mercedes ML 320. I believe the MB stearlership lacks integrity and try to take advantage of me especially because I am a single female. Anyway, when I noticed the "check engine light" on, I took it to the stealership to assess the problem. They charged me $500.00 just to have it hooked up to their "computer" for diagnostics but could not give me a definite answer. The best they could do was to say that I had a potential safety issue and wanted to charge me more to assess the possible problems.

I wasn't about to give my very hard earned dollars to someone who couldn't give me a straight answer or at least a half decent one. A few days later, my window switch quit working. I bought a new switch and changed it myself (after some trial and error), because I refused to allow the dealer to charge me an arm and a leg.

Then my A/C went out. MB wanted to charge me an arm and a leg. I spoke to a very credible mechanic. He told me to first check the fuse. I discovered that it was indeed a burnt out fuse. Later, my other window switch quit working and found that the fuse burnt out so I changed it myself.

A few weeks later while driving, my car just stalled or died. It wouldn't start up right away. After about 30 mins. the car started up and I barely made it home. I bought a new battery. The car started right up, but then died out after about 2 seconds. After getting information from this site, I thought perhaps I needed to change the crankshaft position sensor. I purchased one from the dealer ($141.00) and had a mechanic change it for me. Unfortunately, that didn't fix the problem. I thought perhaps it was a faulty key, so I used my other key, but no change. It starts up nicely, but dies after 2 seconds.

Can any of you awesome people out there tell me what else I should try? I read about others who had similar problems and it was suggested that it could either be a problem with the MAF or camshaft. One person changed the MAF and it fixed the problem. The MAF on my SUV looks really good and thought perhaps I should buy the MAF cleaner and try that first. Any other suggestions before I proceed?

Thank you!
