For a Mercedes Benz 2005 ML 350, What does the wrench sign with -5400 and increasing on the odometer mean? How do I know when to change the engine oil for ML 350?

Changed out oil and refilled with M1 0W40 - drove all of 5 miles and checked dipstick - strong gas odor. Could this be a faulty fuel injector? Anyone have ANY ideas? Thanks!

I discovered a residue under oil fill cap that looks like peanut butter. The oil on dipstick looks fairly normal. I drive 1/2 mile to work and back - live in CT where temps are COLD. No overheating, no white smoke from exhaust, no drop in coolant. However, there is a "slapping/ticking" noise on drivers side front of engine that disappears when car is warmed up. ANY IDEAS? I was told that it is a blown head gasket! I'm at 132,000 miles. HELP!!

Check Engine light just came on and car now jerks when it is put into Drive. Any possible solution other than getting a new or rebuilt transmission?

I live in Colorado and snow treating chemicals are inevitable. I was my car soon after any snow, but the chrome is becoming pitted and discolored. Seems strange for a car this new. Its always garaged and cared for. Asked my MB Advisor and he said MB doesn't warranty this kind of thing. Seems like a pass the buck deal. Anyone else had a similar experience?

Hey guys so i was just driving my car at 60kmh and the cars engine just gave up the speed started drooping and then it came to a stop. i drove it to my house at 20km/h it was shaking like crazy and then i came home got out the car and there was a lot of diesel leaking from the under of the car,the leaking stops when the car is turned off and when i start it it comes back again.
anyone is this a big repair? or small one?

Vehicle sat for a week and there was a lot or rain falling. In the rear, I noticed some dampness when I opened the rear tail gate. The carpets were slightly damp, especially around the wheel-well areas. I looked for signs of water damage or leaks and there were none. Could this be condensation or should I continue to look? Anyone else have this problem?

My engine computer drains my battery very quickly. Is there any recall for this issue?

I can unplug a plug under the passenger side dash to cut blower off completely but when I plug it up again it blows heat full blast nonstop.

ML 350 2004 Transmission and Differential (front and rear Axle) Oil used

esp cuts out when bouncing over rough roads,turning and even when parked,when it also refuses to shift to neutral and needs to be moved before it will release.cruise is released at the same time.switch module was replaced but no help.I feel it's a sensor problem in the front suspension as it always happens in conjunction with front suspension movement or driving through water puddles.HELP.
