Hi. A few weeks ago i had several fault messages showing. Air suspension, Brake guard, lane assist. The car...a8 2013 3.0lt TDI Quattro, had not been driven for a while 4/5 weeks. Started and drove fine for about 10 miles before showing faults. Returned home and charged battery. Car fine. Yesterday, after a run of 30 plus miles i had fault with suspension, active cruise control. I was wondering if a slightly weak battery could be to blame? I am not very able bodied, the battery, being in the boot is hard to get to. I have a good battery tester but i need to know the CCA and the Amp rating. If anyone has this information please let me know.
Living in Scotland the Covid rules are different to England....workshops not fully open.
