Recently bought an 09 audi a4 2.0 tdi 120bhp. Now it seems to have issues starting in the mornings and I think its down on power. I always have to drop it into first when pulling into traffic. The fuel economy is no higher than 26mpg even when trying. Im really worried did i buy a lemon and think I'm about to cry at the thought of what this is going to cost me to repair. Pleas please someone help me.
