Check connection to battery. If the mounts on the battery are corroded then its because its getting a poor connection. Just clean them off.

I had the same problem recently.

To the passenger side of each rear head rest is a small line/mark (about 1cm long). Take your allen key from the document wallet (or a piece of coat hanger about 30cm long with a 2cm length at right angles, ie an L shape).

Insert this straight down along the mark. Move it around until you get it into a small hole where you will feel a springy resistance.

While depressing the spring fully, get a friend to depress the headrest fully. Doing this on your own may be possible if the roof is down, but unlikely if it triggered with the roof up.

Release the spring and the headrest should be back in position.

All those warnings are controlled by the computer, so it might be a computer glich. But most likely it was hot in the car and maybe even humid in it that caused an electrical component not to work. Then when you started it up the next day it was cooler or less humid. Which is an indication that something is getting weak (electrically).

Posotive can be found in hood driver side next to fuse box. It is a small rectangle box. You can hook negative to any solid ground on the car.

you have to go to authorized workshop

You can not reset the SRS system without speciallist equipment.

The light on means there is a fault or something has been disconnected.

left tun signal means you most likely ha a bulb blown on that side.turn key on turn on signal light to each side and check your lights out side for one thats not working.

you can try disconnecting the battery again and see if the light goes away but usually when a srs light comes on the only way to clear it is with the 'sds' which the dealer has and sometimes the independent shops might have one too. Mercedes doesn't allow you to reset it from the vehicle due to it being safety related. when the srs light is on all your airbags and seatbelt etr's are disabled. if your vehicle has pre-safe then you will have to just drive it around til it relearns the steering angle sensor again. if that's the case it will say see owners manual in the display of the instrument cluster when showing the fault.

Suggest you have bearings inspected/replaced and oil pump checked as there is no longer a real oil pressure check in the system and knocking at temperature is slop in a bearing or lack of lubrication.

Assuming you already have checked there is spark at spark plugs. It sounds like starving fuel. This is a problem with the Cold start valve not working. Its function is to spray fuel to assist the start. The valve needs to have a turn on signal from the ECM which reads the coolant sensor before giving a signal to open the valve.
1- If the coolant sensor gives erratic voltage then ECM will not turn on the cold start valve.
2- IF the ECM give the signal to turn on, the solenoid inside the valve gets stuck then the valve could not turn on.
Troubleshooting is time consuming that is why the cost is high because replacing the wrong expensive parts could not make it work and who bears the cost, plus the shop reputation.
