After start/stop engine doesnt turn on

Post by Sdenizgenc » Tue Mar 31, 2020 1:06 pm

Basically, at the lights when stopped and start/stop turns off the engine when it goes to re-ignite it sounds like it is and for a split second it does and then turns off and says start engine manually. And after 20 goes of retrying to start engine it works in the end..

Low battery voltage? I`ve had several VAG cars with start stop and when they played up it was battery voltage , though system should detect this and disable s/s

Apparently the AGM batteries fitted to Start Stop enabled cars do not like the temperatures usually experienced under the bonnet of a modern vehicles. This may explain why these batteries are not lasting long.
