A170 Gearbox problem

[kkdigger]

Hello Guys

I am Dinos, I am new to the forum. I have a Mercedes A170

I have problem with the gearbox i think. The car wont move or reverse as it should.

I need to press the gas slowly slowly until it start moving (take about 12-15 seconds).
If i press the petal too fast then it start moving but it is kinda confused, it accelerates very fast and shakes.

Anyway i put it on a Diagnosis machine an got the following errors:

I get the following error codes:Petrol (266.940 - SIM266 - MT/AT - 169.032/332)

Hi

How old is the A170 (must be a W168 pre 2006 model)?
How many miles?
Is it an automatic gearbox or one of those semi-automatic gearboxes with a clutch pedal?
If automatic does the dash come up with an "E" error code when you put it into drive?
