The ability of a battery to crank and fire the engine is not evidence that it is in good shape. That was true years ago in the days of points in distributors, but not since the advent of sensitive electronics. I suggest you get the battery properly tested (not by a multimeter). I'd go further and say that if it is more than five years old you should renew it irrespective of the test results. Don't forget to get the new battery coded to the car.

Hi nothing will throw up stop/start problems more than a bad battery also the stop start won't work if you have the aircon on, a bad battery will cause all sorts of weird problems as these vehicles rely heavily on voltage continuity, sluggish is the last gasp before you start getting Can gateway problems, bet if you plugged it in there would be a few low voltage faults, don't know what milage you have but I never replaced my starter in over 200,000 miles, mind you I never used the stop/start as it knackers you r flywheel and ring gear.

Hi, I shortened the wording and it let me post, thanks to everyone who replied. David

Thank you for your reply, I forgot to mention the battery was replaced in February of this year so brand new really, I did think that about the ecu Im going to take it to a vag specialist and see if I get the same answers. Cheers
