mine did the same thing, finished up calling aa out my car is a 2009 1.9 td and on checking the battery was the original one (11 years old) new battery fitted no problems now
is it worth doing a remap on my audi a3 its done 106000 mile runs like a 2 year old.i have it serviced every year and recently did a southern spain round trip without a single
concern. (except rear wiper likes to turn it self on /off now and again)
