Our ML350 continues to impress & disappoint.
On the impressive side, it's gone 6000miles in the last year since the engine was refreshed, with at least half of that towing something. The driving and towing has been excellent with my only complaint being the lack of trailer brakes (because HAL doesn't want to provide the +12V signal to brake control plug).
The good towing manners are especially impressive in light of a recent trip across the CAT scales which showed the rear was about 80# over GAWR. Some hitch adjustment and trailer weight shifting should fix that.
It came in the shop for the first annual oil change. I knew the engine was losing a little oil, though it hadn't needed topped off. When the belly pans were removed, the oil loss looked much worse than expected. Just half a litre of diesmal oil can be quite messy. Everything underneath is black & drippy.
The sound absorbent foam bellypan lining was saturated. Since the pic was taken, the foam has been scraped off and draped over the firewood pile to be burned in the fall. We'll see how much oil actually drips outta the strategically placed low point holes in the pan versus oil previously absorbed into foam.
Note to self: don't absentmindedly drain 8.5l of diesmal oil into 2.5gal drain pan. Use bigboy pan next time.
Other than oil creeping out of valve covers & pan, it looked great. All fluids nominal, belt is still new, brakes are 75%. Based on the success of the oil change, I spliced together the previously snipped brake signal wire at rear body module & plugged in brake controller, just hoping it might decide to play nice. No joy, it lights up to indicate power & ground, but doesn't get a good brake light signal.
I'm thinking of installing a physical brake switch to apply +12V to the brake controller. Will post up here if it works (or doesn't).
Need to go back through this thread to find WAEs notes on attempting to reseal the oil sump . At 1/2 litre annual loss, IDK if it's worth attempting?
