    I have a 2014 A8 with electric open/close boot, soft close doors etc......

    Recently the boot has periodically failed to open or close fully on the first attempt:


    • It was believed to be a battery issue as the original battery was 4yrs old. The fault disappeared after a 370mile run to Cornwall and back, however then fault reappeared. The car isn't used that often and was probably sat around before its purchase in April 2018.



    • The original battery was bench charged however the fault reappeared.



    • I have since purchased battery from Halfords based on recommendation from the registration number, alas this did not cure the fault. It has since been established that the Halfords battery does not contain a Battery Energy Management code and therefore could never be correctly coded to the car. The assumption being that the car believes that the original battery is still in situ, Halfords stated that it had 72% of its life left. Halfords are refunding this battery under sale of goods act.



    • I have bitten the bullet and had a main dealer battery fitted, alas it has not cured the fault.



    • The main dealer did attempt to set the boot height adjustment by holding the 'close' button for 4secs, however this did not cure the fault and the rear lights/indicators did not flash as they would say on a Q5/7 tailgate adjustment.



    • Weirdly the fault also occurs when the engine is running on either the door switch, boot switch or remote, however once the boot opens fully and closes fully, it will repeat this operation successfully on every attempt, say 10 in a row.



    • The last line of defence is to test the voltage of the new battery charge and then bench charge it as it is felt by the main dealer that the battery might not be at fully charged because it has probably been sat on a shelf for a fair time.


    Google research has failed to identify any common issues with A8 electric boots, so any advice would be greatly appreciated

    Cheers,

    Steve

    hiya steve.

    i had the same problem with mine.i got a 2014 A8. It would only open a bit and not close properly,i scanned it and it came up with hall sensors in motor 1 for rear lid- short to plus. i bought a secondhand motor off ebay for £60 and that sorted it.
    then i had another 2 faults- function limitation due to under voltage lower limit exceeded.
    supply voltage b+ lower limit exceeded. these 2 was because the battery was no good.

    you need to buy a bosch AGM BATTERY or any make as long it is AGM. Its for the start stop.

    hope this helps.

    Well, currently it's now playing nicely. I have opened and closed it to it's full extent and pressed and held the boot button in an attempt to reset the range of movement though Franky I don't believe there is a setting for a boot as apposed to a tailgate.

    I had it washed the other day and I saw the guy try and manually close it, he then realised and pressed the button, the boot had a moment and has now settled again.

    I was going to book it in to VW-Tec in Chelmsford but they like Audi like the whole world have never heard of this symptom balanced against the diagnosis/fault finding that's been done aka VCAS scan and new main dealer BEM battery.

    So as it stands its all good and still up for sale for minus £1000 of what it owes crazy really as its a beautiful car
