new member with questions, 96 S320
Finally got rid of the 535i, and bought a garage kept 96 S320 for 8 grand. 118,000 miles. Trans just redone (5 grand) at a dealer less than 1000 miles ago, owner got a new one and wanted to sell this one, so I picked it up for 8 K. I'm new to Mercedes and am loving this car. Here is what I did to it:
ignition wires looked OK but when I inspected closer found tears
and cracks and when I pulled on them they tore. Dry rot. REPLACED
#6 cylinder had a mis-fire due to water in spark plug cavity and
cable was orange with rust pudding gook. Not sure how water got in
there unless someone took high pressure hose to engine. I cleaned it
all out and installed the new plugs and wires
Old plugs looked OK, worn and old but OK. No oil or carbon deposits and insulation was cream-tan in color indicating correct temperature range and they were original Bosch factory type plugs. REPLACED PLUGS
Coolant system was cleaned and refilled w/ MB Original coolant with no leaks
Engine test temperature is excellent and radiator and engine block rinsed out superbly clean. No debris or muck.
Installed new Headlamp lenses; looks VERY nice and new
Cleaned all electrical plug connectors and applied an oxide inhibiting grease to
metal connectors to prevent future connectivity problems or corrosion
Did some routing maintenance to wiring harnesses and vacuum tubing and
rebundled them to avoid hot parts and prevent burn out, etc.
Replaced the cam sensor electrical plug plastic connector w/ new
applied adhesive silicon to the inlet air temperature sensor as it was
falling out of cowling vent
Spent half a day with degreasers and kerosene and hand wiped almost
every inch of motor and transmission top to bottom, of the 10 years of
gook and grime buildup. Very nasty. No major leaks found on either the engine and transmission. Looks much better too.
Front suspension and steering looks excellent and all parts were tight
to static pull tests.
Installed new hoses, belt, etc.
BG Transmission conditioner added
All new filters installed
Performed fuel rail pressure test as I thought the fuel regulator diaphragm may be struggling w/ new fuel filter not having any resistance and it was causing some stumbling on acceleration. I thought the pressure regulator diaphragm was weakened from having the pressure reduced from partially clogged filter and now with new clean filter it has full flow and cannot adjust in small increments on rapid demand of pedal for new higher pressure. REPLACED and it runs great!
Power steering filter and fluid was changed out and was dirty as expected
Totally re-did the brakes: Rotor discs, Flex hoses, New pads, Clean and lubricate calipers, Bled brake system w/ MB approved DOT4 original fluid.
(During front brake work, front hub bearings to be removed, cleaned
and re-installed w/ Mystic HT6 High Temp Grease. Had to replace
inner bearing seals b/c condition was poor)
Drained and refilled rear differential w/ MB approved synthetic 75W90.
Added BG engine cleaner to current motor oil; operated engine and then drained off waste
Oil and filter change w/ new MB approved Pentosin 15W/40 Synthetic
and BG MOA additive
Adjusted and secured interior console hinges
NOW, a few questions: (Sorry to bore you; I appreciate the help)
1) This car looks great. It seems to run great. There is a very, very slight vibration in the steering wheel on occasion, I suppose the steering shock needs to be replaced. It is barely noticeable, but present at times. Is this just a personal preference? Should I replace this now? The car does not pull at all while on the road or while braking.
2) Was 8k a good price? I kept my 1990 535i for 11 years (bought in 96) and needed a bigger car. Can I expect a good life out of this car even though it has 118000 miles on it? Should I expect any major issues with the age?
3) THE ANNOYING PROBLEM! I have recently noticed a very slight buzzing sound (for lack of a better word) coming from the area on the roof where I control the interior lamps and sun roof. There are a bunch of roof/light switches on this "console" and the sound is emanating from this "console," from an area that looks like a mini 'speaker' or "vent" next to one of the switches. This "vent" (again, for lack of a better word I call it a vent because it looks like a tiny vent or mini-speaker) is about the size of a dime, and round. When I hear this annoying buzz (very faint, but noticeable if the radio is off, at least by me - my wife hasn't noticed it yet) I can apply very slight pressure to the entire console, or specifically to this dime sized "vent", and the thing shuts up. When I shut the engine down, the noise does not immediately cease; but rather, it "winds down" as if perhaps a fan of some sort is shutting down. CAN ANYONE ADVISE WHAT THIS SOUND IS, OR WHAT IS CAUSING THIS NOISE? IT SEEMS PERHAPS THERE IS A VERY TINY FAN THAT IS UP IN THIS "SWITCHING" CONSOLE, THAT HAS SEEN BETTER DAYS, BUT I DONT KNOW. THIS IS ANNOYING THE HELL OUT OF ME, ON WHAT SEEMS TO BE A VERY ENJOYABLE VEHICLE. THANKS FOR YOUR HELP.
(I use the yamahajetboaters.com forum for my jetboat, and am hoping this forum is as helpful as that forum......)
