Hi people. anyone had trouble with their start stop on A4 B8. Mine doesn't work when stationary. I know it won't work when car is in certain situations. Any ideas would be grateful.

thanks

Hello Daniel,

Could you explain "doesn't work when stationary" since as far as I'm aware, this is the only situation it normally works under -so I am wondering if it doesn't work at all.

Can see the car is 6 years old, and as they say, you live and learn, and this must be quite early? for this system. You would normally expect the original battery to have a service life beyond this age, but I'm not sure what can be expected where this stop/start system applies, since it obviously puts a far higher demand on the battery and indeed the starter motor. 

Since this "intelligent " system depends on monitoring the battery charge/condition level I would think it is worth getting a good auto electrician to measure the serviceability of the battery, after a good run to ensure it is fully charged. 

If it is found it does need renewing then you need to ensure the battery is of the correct (modern) type which deals with intelligent charging systems. 

Good luck in getting it sorted.

Kind regards,

Gareth.
