Please if someone can help and if I need to replace parts let me know which ones and if it works to replace with used ones. Thank you in advance.

Your first error is nothing to do with the stop start system. Just an intermittent error with the rear HVAC control. is it functioning properly? The second error refers to the battery monitor which is fitted to the positive terminal on the battery. have you checked the terminals and free from corrosion? Check the connection is tight and the cable that is plugged into is ok. Wiggle the wires that go to this connector and make they have not snapped/corroded even though the cable may still look attached.

Thank you for your reply Morski. HVAC you mean rear controls of clima no ??? Its working but I think people when they get in the back they pushed a button or is stuck I had an error like a button stuck so I will check. I will check also the battery monitor and check for corrosion if noting working and no corrosion I should be thinking of replacing it ??? Thank you.
Also Humidity sensor or air quality sensor can influence start stop system ?? Thank you again.

Yes HVAC rear is your rear heating controls. How long as the S/S not worked? You do know that in this cold weather its rare for it to work as there is so much demand on the battery. What year is the car, do you drive it often? If not maybe worth connecting a smart battery charger to sort out the battery.
I dont think the Air sensors affect the S/S however the coolant temp sensor does
If all else fails yes find either a guaranteed used part and fit that. A new one is circa £145. part number is in your scan: 8X0 915 181.
if second hand then look for cars: 2008> A4, 2008>A5/S5 2009>A6, A7, RS5, 2011>TT,

SS not working for about a year when I been in Europe at -20°. In November checked the battery is at 96% repaired the alternator but still not working properly. Ss was working properly even in cold weather ,short trips. I have A6 C7 2011 2.0 Tdi. I drive every day, starts perfect. I will definitely check. I saw the part number.
Gateway control unit 4G0907468C ?? His role,any ideea ??? Could be faulty ???
Battery voltage is 14.66 car running.
Thank you for your reply
