C180 merc My c 180 merc is in limp mode how do i get it of limp mode

check the injcctos, they we're clogged

If you have a small odd shaped key on the keyring there is a socket under the steering wheel (in the plastic housing) which mine fitted. By turning the key left or right in the socket it resets the light. I found that the flashing light indicated that the alarm had been triggered at some time when I had been away from the car and had switched itself off after a time. If you have this key you could try that.

The best $100 dollars I ever spent car repairing is a OBDII scanner. This lets you diagnose your own problem. Even if you can't fix it you can direct your mechanic. I am not familiar with code 1630 on your Mercedes.

Spin the barrel fuse then check the column switch.

You need obligatory to access the Engine Control Module (ECM) using suitable diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC (Diagnostic Trouble Codes) memored. Then you will be full informed about bad components, and you will be able to repair & replace bad pieces and reset the ECM.
Yes, it could be a fuel pressure problem regarding the acceleration, but without access the ECM memory it's not a good idea to change pieces.
Regarding the limp mode problem, I suppose you have a CDI (turbodiesel) engine. I guess that in your case the turbocharger is responsible for engine losing power.
The car goes in "limp home" mode.
After scanning the ECM (Engine Control Module) with a diagnostic equipment you will find this: Turbo Boost pressure control exceeded
1. Engine stopped and ignition switch off. Check all pneumatic connections and hoses between turbocharger actuator = pressure unit for boost-pressure control, boost-pressure control solenoid valve, vacuum reservoir, EGR control solenoid valve, intake-manifold flap solenoid valve, EGR valve with throttle - part of intake manifold. Also the vacuum connection between tandem pump and brake booster. If you find something wrong replace parts. If not go to step 2.
2. Extract the hose of the turbocharger actuator = pressure unit for boost-pressure control part of turbocharger. Instead of the original hose you must place another 1 meter long hose with the same inside diameter, and then you check to inspire yourself the air from the other one extremity of this hose. The mechanical connecting rod of the turbocharger actuator must have a smooth and whole motion. If you can do that with your mouth, then you must replace the boost-pressure control solenoid valve. If you can not reach this with your mouth, then you go to step 3.
3. This is the most difficult work. The problem is that the soot particles deposits inside the turbocharger plugging the variable nozzle geometry mechanism = adjustable vanes of the turbine. If the turbocharger actuator is not able to adjust the turbine vanes the charge air pressure increases too much and ECM goes in "limp home mode" = engine protection software. As a result the "limp home mode" engine still running until you turn the engine off (ignition switch off) and back on when the "limp home mode" is deactivated, but the fault still remain in ECU memory!
4. You must be able to extract the turbo from the engine and then to disassemble the turbocharger, clean inside adjustable vanes mechanism and refit all.
