Hi all, My Q7 2020 suffered the dreaded amber battery warning in mid March. Luckily I have quality scanner and found fault code P0CA700. Contacted local Audi people and they advised to go to nearby Indy who has ODIS. This I duly did and was told that it points to the starter generator and not to drive it far. Booked it in at Audi dealer and after initially stating in writing that its the starter generator they cannot find my fault code number (strange as ODIS apparently stores older intermittent codes) Contact Audi UK (in Cape Town South Africa). Talks between Audi UK and dealer result in wanting me to sign up to cover further investigation (not on your Nelly) Heated argument with dealer as I believe I'm being shafted by greedy dealer and a less than responsible Audi UK. They are not prepared to change the unit until it breaks, unlike North America, they appear quite prepared for you to have this crapply built unit fail on you and leave you in the most incredibly dangerous situation where you could be on a motorway where the hard shoulder is a live lane and all the lanes are heaving with traffic with little or no steering or braking no electricity to run hazard flashers nowhere to go and if you try to get out you can't get the grandchildren out of the back because the rear locks are deadlocked. If you remain in your car to await rescue you may have up to 6 to 7 mins of air bag cover but after that the airbag capacitors are drained and they will not operate. In other words you are driving a death trap. All Audi UK are interested in is bean counting not human life. Why an earth aren't the relative bodies in the UK swarming all over this or are they in bed with the motor manufacturers.
