Just for drill, I threw a piece of cardboard under the 530... checked it later that day... big leak!!
Now, I had it at the dealership in August for an oil service, an A/C charge, and replacement of a leaky Schrader valve. Everything check out fine, no mention of oil leak, etc. Oil level from computer says the level is a green "OK" (no dipstick)
Monday I took the car up to a friend's shop that is relatively close by to get it up on a lift....removed the large plastic panel, a smaller one, and an aluminum panel that together cover over the entire under-side of the engine and then some, to discover lots of oil/sludge mixed with dirt, sand, etc on the top surfaces of these panels.... clearly its been accumulating there for quite a while! Brake cleaned things off pretty good under there... ran the car for a while, and it looked like it was coming from an area that could only be the rear main seal
This is going to be a big repair bill, plus it takes a special tool to remove and install the new seal, which VSR will need to find/borrow. That couple thousand $ I made selling it myself, rather than trade it in when I bought the ML350 a few weeks ago, is soon to be gone!!!
I plan to call the guy that bought it tonight and tell him the news... shouldn't queer the deal., especially since I'm getting it fixed, but man, what a bummer. How does a 90K mile, well maintained car have this problem?? Shit happens, but this really pisses me off! That large plastic tray hides everything, and you'd never know you had a problem like this, or any other leak for that matter, until it gets big enough to spill over the edge somewhere.... unbelievable!
