Question about 1994 Mercedes-Benz C-Class

1 Answer

I have been chasing a problem for months and it is costing me a fortune - $600NZ so far ! Start the car, drive to destination, turn off car, refuses to start when you come back to it. Everything starts up, cranks over but won't fire up. Rplaced fuel pump, replaced engine wiring loom, replaced cam position sensor, replaced rear section of fuel line, replaced power protection relay. All done by MB agent - beginning to think I am being ripped off. Last couple of times Instaed of calling MB agent) I popped the bonnet, lifted the cover by the windscreen on passengers side, pulled out and refitted relays and plugs, gave the power relay a wakeup call (tapped it) and the car fired up ! Any sugestions as to which parts should be replaced ? MB agent says to replace the engine coil loom and ALL the relays - another $100 !!

I have read all you say and the first thing im goin to say is [yes] you are being ripped of, any good mechanic whould have tested the engine for all the above problems,even if this car had been put on a computor to analise the fault it only costs 30 dollers but atleast it would have pinpointed the problem,also forget about engine coil looms and all relays....this model had an power relay problem especally this older model the fuel relay also give problems so you are in the right area but they also had a problem with the wires ie water getting in to the bottom of the relay holder there are four screw on the top remove and check this area out for rust ,if you will come back to me after this and i will find the problem.adrian,,,,,,,,,,,

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

Iac and throttle body


Cleaning the throttle body is no big problem; simply remove the air filter box, and remove the tube from the air filter box that connects to the throttle body. Spray carb cleaner on the flap valve and all around the flap valve. Regarding you idle condition, cleaning the Idle Air Control valve (IAC) may do you no good. Once it fails, it is usually done. You prob need to install a replacement IAC. It is UNDER the throttle chamber, you will see it when you remove the air tube to the throttle body. I change several of these a month. Common failure.

Maintenance costs


Oil change will cost about $200, tires? depends how and how much you drive and quality you buy. Guess you could spend $200 each. Brakes depend how much you drive but a quality brake job will cost about $1,000. As far as daily driver?well this car is not designed for that, and will probably suffer in stop and go traffic. So would need a tuneup about every 4-6 months at a cost of about $2,000. then you need a mechanic that is trained. Hope you can find one in your area.
