I have v40 Volvo. The check engine light is always on and the dsa light comes on intermittently. When the dsa light comes on the car loses power or hesitates to accelerate. Volvo can't diagnose Ideas?

no idea whats wrong but mine does the same.... it might be the clutch or the gear box.... took mine to a Volvo dealer.. they fixed something but it still broke down again on the way home... not sure they know what they are doing.. do you have any more info ??
