Bought an 08 TDi Golf a few months ago. After I bought it I found it would crank for 10 seconds before starting, or not start at all when hot! Tested the battery under crank and found it dropping to 9.5V. Replaced battery with Varta original.

Now, it starts almost instantly when cold, but seems to crank for 3 or 4 seconds when hot and starts with a jerk. It's never let me down since the new battery, but it still isn't quite right.

It drives and operates flawlessy otherwise - a great car.


Has anyone else had this problem and/or solution?
