My Mercedes is dripping underneath
This in side the car? If so it would be your heater core it leaking sorry iv;e never done one on a mercedes all i can tell you is some heater core easy to replace and some are a major job where the entire dash needs to be disambled to get at it hope yours is one ofthe easy ones
My mb100 van 1997 model
You may have a leaking core or welsh plug. This is a large disk which is used to block off the holes left behind by the casting process during manufacture. They are easy to replace but difficult to access..
It may also be a leaking hose or even a cylinder head gasket but I would suspect a welsh plug first.
Take the vehicle to your local garage and get them to pressure test the cooling system, this will show up the leak a lot easier..
Instrument cluster not working
no other way to solve it but replace it, sad thing is no second hand clusters available (in Manila). Purchase directly from your Mercedes Benz dealer. This will solve your problem, in a quite costly way.
Mercades 430 wont start back when hot for 15
If it is a gasoline engine- check on replacing the thermostat. If it is faulty it will not let your car run warm, making it think it is way to hot too be in operation. part is relatively cheap as well, and labor not too far from that unless you are comfortable under the hood (medium DIY project)
Glow plugs won't work when
Check voltage and make sure that the glow plugs when cold are getting the right amount of voltage, if they are replace the glow plugs
Xenon problem wont stay on
The ballasts take the 12v power of the car and amplify it to 22,000 volts to ignite the lights. After that, they run at a constant 85-95 volts to keep the lights on. You may have a weakness in the electrical system that is causing the battery voltage to drop just enough during startup that the lights won't ignite. Are you turning them on before cranking the engine? You shouldn't do that for a few reasons (if you are) - one, the life of the xenon ballasts can be severely shortened by flickering, and two, having the lights on puts additional strain on the battery while starting, as most of its amperage is needed to turn the engine over. Get a piece of 10 gauge wire (a stereo shop can sell it to you) a couple feet long. Put a ring terminal on each end and attach one to the battery's negative side, and the other to a bolt in the engine bay. This will give your car an additional ground point that can help its conductivity better and it may help to alleviate your problem.
If the problem is simply that the lights will not turn on, you may need either new bulbs or new ballasts. They're very expensive from a Mercedes dealership (on my Audi, the bulbs are over $200 each and the ballasts are even more) but you can find them online for a fraction of that.
My 2004 mercedes-benz s500 radio turns on then says system unavailable and shuts off. I've tried to reset it to no avail
post all things that fail and work both
all maters
engine starts , runs , drives ok ,day or night?
all other electrical things on the car ,as in ALL do in fact work correctly?
or just the RADIO on the car fails.
many cars now the RADIO is part of the CAN , the car Area Network. and if that fails so does the RADIO.
if is in fact a factory RADIO there from MB.
what to do.
well
check all fuses first. never skip the easy first step and a 50cent cure..
next scan the USA? OBD2 scan port, and look for Radio errors
like COMM failures codes.
can I assume this RADIO is not SDAR , satelite radio
if is did you path the subscription bills? $$$$$$
or
the RD is base Radio and both are in fact CAN bus controlled
so yes, it must be scanned first, after fuses
sorry this is no simple 80s radio, not at all
and is antitheft protected too.
i request this post be moved to cars and not computers.
here is more than 1 fuse, the RD shows 2, F1 and F2
my online docs, are not so good, on all MB.
get the car scanned in any shop.
see the DTC error codes. next.
