W116, BENZ AID - COMMON QUESTIONS AND ANSWERS

I am currently dealing with a very frustrating starting problem with my 300D. This is the symptom: I turn the key in the ignition and sometimes it will start and sometimes it won’t. If it doesn’t start I proceed to turn the key between the off position and the start position. Eventually it starts, sometimes after doing this once, sometimes after 10 attempts. At the beginning of this problem, I knew nothing about automotive electrical systems, so I thought it was the starter and replaced it with a remanufactured Autolite starter from Kragen/Checker Auto Parts (I know this was probably a bad idea). Well, the problem continued and since I already dropped off my (probably) good Bosch starter for a core refund, it’s too late to go back.

I have a 240D 1981 and I recently performed a valve adjustment. The adjustment seems to have gone as planned but when I began driving it I noticed decreased power due to the fact that the tranny was shifting too early on all gears now. I may have 1st of all done the adjustment poorly or may have messed up some vacuum lines to the tranmission shifting system which I don't understand too well. Anyone have any hints?

The cigar lighter in my 300SD doesn't work. I plugged in my iTrip adapter for my iPod and it isn't getting power. I'm not sure if I have to replace the Cigar Lighter unit or if it's just a short. If I have to replace the unit, where can I find one??? I've looked all over online. -tom
