I have a Polo 6 Gti and experiencing the below Please can you advise what could be the problem here my car when i park it a spanner light flashes by the gears but if i switch the car off and on the spanner goes away and the car drives fine the only thing i notice is intermittently when the car down changes from 7 to 6th to overtake there is a shudder or jerk in the change. If you have an idea of what the issue could be please can you quote me on the repair
