Hi folks, I've got a 2001 208cdi, just bought it and drove it home. After 3 days running ok suddenly there is no throttle.the engine starts fine and runs, but the throttle pedal does nothing, so I cant move. the diagnostic port is a small round one, not obd11 so i can't read it . What reader do i need , and any ideas whats up? also any good merc indies near me?? hope someone can help, cos I.m stuck at the moment!
