The below are very easy checks you can do while buying a used car.(from anywhere for that matter of fact) Engine This is the most complicated/expensive part to maintain/replace. Head Gasket check: Open the oil filler cap or the dip stick for any milky white substance, like mayonnaise, if it is present then stay away, it means the head gasket is broken and ...

The symbol is for "Speed limit assist" and is based of a forward facing camera that allows detection of the speed limit and then possibly displays this on the multifunctional display. Information can be found at this site, under the "Steering Wheel( 12 button multifunction...)" > "Assistance menu" and subsequent links from within page.

That is your diagnostic connector. You will need a Mercedes-specific tool to read trouble codes stored by the computer.

There are other factors that affect the start stop feature. I am not sure on that exact model but generally the following things will keep the car engine from shutting off: Coolant Temp too high, or too low The engine has not ran for at least two minutes The AC is on and not in the economy mode Low Vacuum Battery charge low High current draw on the 12 volt ...

There are advantages, but also disadvantages to using a smaller turbocharged engine with a higher power output. The pro's of smaller, turbocharged engines: When not on boost (below e.g. 3000RPM) the engine uses much less fuel. turbocharged engines have a flatter torque curve, meaning they're working closer to optimal level throughout a larger portion of ...

It means "at least". You will not cause any damage by using the higher octane fuel. The reason for the RON 95 rating in the first place, this is the lowest octane rating you can run before you might start hearing pinging or pre-ignition.

You're going to need a new key, as used, already programmed keys will not work. You'll have to get your dealer to order the key as they're not keys your dealer or mechanic can make. You'll need to know your Vehicle Identification Number (VIN) and bring two forms of ID (in my experience) to get a new key; they're very picky about giving out new blank keys, so ...

The Mercedes M103 engine in your 300CE is a proven design, old enough to demonstrate its longevity—lots of them are running around still with 300,000+ miles on them. The head gaskets are pretty much the only serious weak point. If the engine was not burning excessive oil (more than a quart every 5,000 miles) or showing other signs of extreme wear before ...

If the bolt is so obscured that vise grips and welding are not feasible, and so stripped that impact doesn't make sense (I am guessing it is too stripped), I usually do the following. If it's very stripped, you might want to skip ahead to step 8. (Look ahead to step four; you'll probably want to take one of your bolts to the auto parts store before starting ...

Tyre depth gauges look something like this (amazon link) - you can buy them in any automotive store. You press the green bit against the tyre and push the middle bit into the tread groove. The slidy bit at the top will then tell you the depth. Buy one and have a play, it's easier to see than to explain! You should be able to see the 'wear bars' - raised ...

Drop the fuel tank and inspect the contents, looking for jellyfish, fluff, water, dirt, and the bones of lizards... Paulster2's initial comment was spot on. Although I doubt it is a single "obstruction", on a vehicle of this age (especially diesel fuel that can be inconsistent), you can collect quite the library of muckity stuff in the fuel tank. A long ...

Sounds like a lack of fuel getting to the engine. Get it hot, turn it off pull a fuel line and crank the engine, see if any diesel comes out. It could be a fuel line softening up when it gets warm and pinching shut due to the suction from the pump. If thats the case, replace your fuel lines with proper diesel rated lines.

That's a Mercedes Benz C140 body, the coupe-version of the S-class w140 limo. For a list of the models, i.e different engines, that was made; take a look here: http://en.wikipedia.org/wiki/Mercedes-Benz_W140

Any key that has already been programmed to a Mercdes will never work in any other car. Once a key has been "flashed" or programmed to one car you can't reprogram the key. Mercedes keys pair "for life", so once you stick a key in the ignition and it works, it's never going to work in another car. It is true that a Mercedes can accept new keys; when you get ...

There are several things that can cause this - the simplest being the road itself! If you are on a cambered road, the car will want to pull towards the edge of the road... Presuming it's a stronger pull than that, your next suspect is the tracking (wheel alignment) - if this is out it will cause it to pull. Most decent tyre fitters will be able to check ...

I would like to add two valid points to this discussion as well: 1) When producing engines like this which produce more power with lower CC's, they won't be as smooth as their bigger naturally aspirated predecessors. They will have to rev higher just to produce the same power. So lets say you are driving at 70 MPH with a 5.0 V8, you could comfortably ...

After hours of tracing cables, removing panels and taking apart more of the car than I'd like to admit, I figured the issue out. Apparently there's a cable for control current (or something like that). The control current had gone out. The car still kept thinking the lights were on, as the LED control circuitry was apparently using the power the car was ...

Finally found out how to reset the service reminder manually. It was easier than expected. Here it comes in steps: Put in key Turn key to position 2 (this might be tricky, there are 3 positions, but its actually just before the engine starts, all electronics are on, lights flashing on "dashboard") Use buttons on steering wheel to navigate to "Service ...

We had the same problem on a late 2005 W169. Note you do not need to remove the door card if you just want to remove the door lock cylinder and exterior handle. Once you've loosened the bolt holding the cylinder accessed from the side of the door (On ours it was a T20 - T15 would work but there's a chance of rounding off the head) there is a catch above the ...

I would think you should be able to if there is a terminal for the wire to attach to. If the terminal has broke off at the base of the sensor, then it probably won't work. I would use a soldering iron, versus open flame type of iron to ensure the heat is more localized. If you are worried about the sensor not working due to the heat, I don't think I would ...

I just repaired the identical car, the ignition does not come on and the wheels are locked and it sets steering column mechanical fault codes. This means the solenoid that locks the column to stop the wheel turning is faulty, after it receives the unlock command from the electronic ignition switch it tells the ignition switch it is unlocked and then the ...

It very well could be the thermostat. However, did you check the obvious things, like coolant levels and make sure you don't have any air pockets? I had an overheating issue that would manifest after 20 to 40 minutes of running the car, which was due to an air pocket. Usually if it overheats at idle you check the radiator fans, radiator fins bent or ...

A car battery's power will drop with temperature. It would be my first port of call. Since the car ran fine when you had it jumpstarted with the help of your friend, I would have the battery tested to make sure that it can deliver sufficient juice to the starter.

Can you use them? Yes. Should you use them? Depends on what you are looking for. Most of the times (not always) these special tires are just a modified version of a regular tire. What makes them special? Here is a list of common modifications: A softer compound. This typically increases grip at the expense of longevity. A special size. Sometimes car ...

There's a lot of good answers and discussion about electrical issues and other complicated things, but to me it sounds like the steering lock is under tension and not allowing the key to turn all the way and start. You can sit in almost any car, turn it off, remove the key, and then turn the steering wheel until it clicks into the locked state. The rubber ...

There are a few ethical options available to you. Leave a note/poster nearby stating that you have found a lost key Post on social media that you have found a lost key so word gets around Hand in the key to your local Police Station or Lost property It might also be worth having a look around where you found it to see if there are any possible cars that ...

I cannot post a comment so in addidion to Terry: go to facebook, join a local community (from where you found the key) - something like: buy and sell Philadelphia (no idea if it exists) - post that you found a car key (no too precise description) and ask people to share it in the surrounding area. Hand it to the Lost property or police and include that ...

can I switch that electronic ignition starting with an old-school key? No. At least, not anywhere near 'easily'. That ignition switch, from what I can see, has about 13 low-current wires. At least a few of them are data lines (CAN bus!). It also directly controls the steering wheel lock (ESA lines). And another snippet: That's very different from an old-...

You might have a slight leak in the fuel line, this will draw air over time and cause you to have to crank till all the air is purged. Then it starts fine. Difficult to locate those fine leaks. You may not see any drips because the fuel drains back into the tank.

Four months went by between when you last ran the vehicle (December) and when you tried to start it (April). Just like gasoline, diesel fuel can also "gel" and clog up your fuel filters. As a first, low-cost troubleshooting step, change both of your fuel filters. You can use some starting fluid to try and start the vehicle after changing the filters. If ...
