Immoderately Caffeinated/ Vintage Moderator
I'm with you Zeiter on this. My mate has two identical and pristine 123's and they feel like tractors. I tossed my rusting out but wonderful old 124TE workhorse for an immaculate and impeccably maintained S202 kompressor because the front sort of looks like a 124. What I didn't know but should have checked was the $2000 ignition switch and the fault where the CPS sensor leaks oil into the loom, the oil migrating through the entire engine bay loom into the O2 sensors, the ECU, the MAF sensor and my brain, virtually writing off the car.:cryingI believe all of the newer models than the 124 require proprietary software/readers in order decode various ECU/CAN-bus outputs. I wish they were more like VAG, which allows folks to use relatively inexpensive VAG-COM software and a laptop to not only read, but manipulate the ECU settings for certain functions. MB seems to have chosen a route that prefers that only their factory techs be able to do those sorts of activities...or at the very least, those with deep pockets. I'm well outside my element with the newer MBs, but I don't think I'd mess around with anything newer except for the 203 and 211 models. I'm pretty much a one-trick-pony though, so I'm just sticking to the 124s.
I'm now looking at a 1994 124 E220.
Edit; and every freekin' time I had to get the codes read MB wanted $200 just to get a fault print-out and the engine light off using their exclusive STAR program. I'm really beginning to hate this car.
