Hopefully some of you can offer suggestions as to the diagnosis and cause of the following problem I’ve been experiencing over the last week with a 13 SEL TDI.
I first noticed when I started the start sequence, the car failed to turnover. I would re-initiate the sequence and the car would start almost instantly. This happened several times during the first start of the day, and I assumed I failed to press the brake pedal adequately. Now the problem has evolved to instances during the day when it starts, it stumbles and dies. Upon restart, it usually starts and runs fine, but there was an instance yesterday where it took several efforts to be successfully started. The car has 56,000 miles, and had a new battery from VW installed last year.
TIA
