This Utube video is great. it is for an S class but ithe process is the same.

Switch spark plugs, ignition coils and fuel injectors from cyl 1 to 3.
See if misfire goes to cyl. 3. If that happens replace the damaged part.
If is still on cyl. 1 check the compression of the cyl. 1.
If that's ok see if the air mass sensor is working fine.
Also check if there is oil in the plug of the lambda sensor.

Is this the ac fan or cooling fan? For the cooling fan, check relay in the fuse box. The relay could be stuff and if the relay is ok then check the water sensor. The sensor should be on the radiator.

a black box under hood that has clips on it loosen any clamps open clips and box replace filter and close box tighten up everything make sure you have correct filter.

Under the hood rectangle black box near the heater valves, between the suspension top mount and the front screen. There are some additional ones near the battery in the trunk.

Battery is located at the back of the engine compartment in the left rear corner covered by the dust filter.

burnt cd's are 1.3mm thick. a non burnt cd is .9 - 1mm thick. they get stuck, it happens all the time. why now? just unlucky.

Chain failure is pretty much game over. You could bend your valves and all sorts of other stuff. That price is a little high, but it is a very invasive procedure. If you were driving an 88 Toyota Corolla it may be a little cheaper, but Mercedes doesn't make anything easy to get to. It will probably take close to 6 or 7 hours from start to finish.

I would shop around a little more just to try to get a good deal, but I would say that $900 would be the lowest you may get. I know this probably wasn't much help, but that is just how it goes sometimes. Sorry.

i drop a dime inside the hole of where the lighter goes, and now my new car charger will not work. where is the glove box? In what order do i replace the old fuse so i can get a new one!

hi go to your main light switch rotate it to driving headlamps and pull the swithch towards you it should slide out slightly in stages and operate the fog lights
the headrest switch is a button in the center console near the gearshift

check the fan relay for proper operation. Check the engine coolant temp sensor. If it is disconnected or stuck at full cold, the fan will not come on.

It should be in your service book, basically an oil & filter change plus lots of checks but it also depends on mileage.

P0172 - System Too Rich (Bank 1)
Basically this means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.

Note: This DTC is very similar to P0175, and in fact your vehicle may show both codes at the same time.

Symptoms: You will more than likely not notice any drivability problems, although there may be symptoms such as a misfire. This is the next code explained.

Causes: A code P0172 may mean that one or more of the following has happened:
* The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
* There could be a vacuum leak.
* There could be a fuel pressure or delivery problem

Possible solutions include:
* Inspect all vacuum and PCV hoses, replace if necessary
* Cleanthe MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
* Inspect fuel lines for cracks, leaks, or pinches
* Check the fuel pressure at the fuel rail
* Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
* Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)


P0301 - Cylinder 1 One Misfire Detected
A P0301 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #1.

Symptoms may include:
* the engine may be harder to start
* the engine may stumble / stumble, and/or hesitate
* other symptoms may also be present

Causes: A code P0301 may mean that one or more of the following has happened:
* Faulty spark plug or wire
* Faulty coil (pack)
* Faulty oxygen sensor(s)
* Faulty fuel injector
* Burned exhaust valve
* Faulty catalytic converter(s)
* Running out of fuel
* Poor compression
* Defective computer

Possible Solutions:
* If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
* If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.


Keep in mind that the "misfiring" are not only for bad O2 sensors, check the other componentes that I tell you before.
