wierd c43

hello, i went today to see a 1999 c43 amg with 150 000 km that i found on the net.
i tried the car and everything seemed perfectly correct. but when i got on the highway, i hit the pedal to the floor and as the car was speeding, i noticed the headlights flashed for a fraction of a sec, ( the car was still speeding and the engine didn't cut at that moment) then i tried the same thing and the headlights did the same thing again and again.
when i parked the car, i tried to open the sunroof witch, while opening, stopped, and i had to release and press again on the button so i continues opening. ( i had to do the same thing about 5 times before the sunroof was completely opened). when i closed it back, i didn't jam as it did while opening. then, i reopened the sunroof but that time it didn't stop or jam.
what could it be?
anyone could help?
thanks.

Not in the middle of the night!..

Sounds like a interior network issue. There are 10 computers on that network.
Any of them could cause those electrical issues.

Most likely a door control module or the PSE (central locking module)

The sunroof sounds like it lacked synchronization, and you accidentally performed the procedure.
