Can't turn MB rotors, so if they are warped or too thin, toss and get new. Rears are like $25 each, fronts $40 or $60, depending upon if they have vent slots or not.

If they show a distinct lip at the outer edge were the pad doesn't cover, they are too thin and need to go. If you just put new pads in, they will jam on the spring eventually and stick the pistons in the calipers, more work.

Sadly, everyone with an older benz they are "tired of spending money on" lets the brakes go to hell. Very scary.

Verify that the overflow lines aren't leaking before jumping on an injector. You might want to open the cap nut and re-tighten with the engine running, too -- that will flush any crud under the cap nut out. If it is actually leaking, someone has taken it apart and it didn't seal properly. To fix that, remove the injector (deep 27 mm socket from Sears) and put it in a vise so you can unscrew the top part. Take it apart, flush with solvent, and reassemble -- it's got something in the sealing surface. No copper seals, just precision steel contact surface. We found some red lint in the one on my brother's car that leaked.

Probably the overflow line, though. If the old lines were hard, make sure you got all the bits off the nipple -- I've seen that stuff as hard and brittle as glass, and a small ring of it will cut the new line. Don't use substitutes, either -- unless you can find actual diesel fuel line in that size, nothing else seems to last long.

Sunroof is a "simple" one, I believer (no tilt, just back and forth), travel is limited by torque load. If the motor runs, it needs lubrication (use MB paste), if the motor doesn't run, check the fuse-- in fact, probably a good idea to replace all the fuses, they get old and corrode.
