It's normal for the alarm to go off if it was set with the key fob and then unlocked with the metal key. The manual should explain this.

If the battery is removed you have to re-align the windows to the fully up position. So, get the window to the top and keep your finger on the button for about 3 seconds you will hear a click. the next time you operate it will go all the way up in one go.
If this does not cure it the battery connection may the problem.

Water temp sensor grounded. Replace sensor or check wiring for condition.

There is a good video on U-Tube to illustrate this process. It's difficult to explain unless you can see the job being done. You have to place the vent fully up to release the bottom clips and fully down to release the top clips.

I would say the best thing to do here is to contact a Mercedes Independent dealer, and show them your list of fault codes.
A wiring diagram with the electrical connector numbers is required, and there are not many of them around for Mr. DIY.
R12/6, R12/7, n2/7-15r/15 should be identified on the diagram as either wires or connectors. I had a similar readout on my 2001 C240, when oil from the rear crankshaft oil seal was seeping out of the gearbox bottom drain, and saturating the area where the main electrical connection entered the gearbox. something like that may be the problem.

Hi, this is a common symptom of a clogged fuel filter that is straining the fuel pump itself.

When you accelerate, this initiates a rapid fuel flow through the lines. if the filter cant pass the proper amount, its will stall or hesitate the engine and cause sputtering or loss of power. due to this clogged filter, the pump cant keep up with your acceleration demands at this time. the reason for the power pick up upon De acceleration, is because the lower amount of fuel is able to pass through quite easily but, as soon as you demand more power, the clog will obstruct the more intense flow of fuel to the injectors.

Simply replacing the fuel filter and pump will fix this issue.

Please rate and god bless:)

I have had 3 w124s. The problem is probably in your instrument cluster itself.

Press the menu option on the steering wheel till you get to the temperature. press the up or down key until you get to see 'Run Flat: Active'. Then press the reset key (the key near the steering wheel to reset counter) that should do the job.

Try disconnecting the battery for 10-15 minutes to reset everything . Or pull the fuse for the radio which will do the same thing.

Noise from interior blower motor? If in engine compartment, go to drive belt. Shiny or cracked, replace. Hand spin the free spinning wheels for the belt to see if any are hard to turn. (Be feeling for roughness). If none, change belt. Take picture or make drawing of how belt is routed before removing.

Both actions are used to select reverse on various makes of vehicle, have you tried seeing if there is a collar fitted just beneath the gear knob ? you normally have to lift the underside of the gear knob to get it into reverse

I am not familiar with the model. Replacing pairs or sets has always been best practice even though the kerb side suspension tends to suffer a great deal more wear and tear and a greater likelihood of damage.

I imagine there is a device to monitor the suspension height that is either faulty or maladjusted. As it is a late model Mercedes I expect it is a fully computerised car and it is probable a clever fellow with a laptop and the right software would be needed to reset the default values after a repair and possibly even tell the system it has been repaired...

The issue is probably due to damaged contacts on the membrane keypad or damaged tact switches within the fob. If you're comfortable doing so, open the fob to gain access to the switches or contacts. If it's a membrane style button then carefully clean the contacts on the circuit board with something like isopropyl alcohol or electrical parts cleaner. If using electrical parts cleaner, be careful not to get it on the plastic as it will likely soften, warp, and / or discolor the plastic. You're better off to spray on a cotton swab and clean the board with the swab.

If your fob uses tact switches, then you may opt to remove the switch from the board which will disable the panic feature. Or, if you have given up hope on the second fob, pull the switch from it and install that one on the otherwise working fob.
