So, yesterday I was travelling from Bridgwater down to Exeter for my first covid jab. Just approaching J29 of the M5 (so only about 5-10 mins from the vaccination centre) and the car decides to shit itself. Dash lights up like a Christmas tree, all dials stop reading, wipers come on and won't stop and loads of faults appear on the idrive.
I get the car on the hard shoulder, turn off the ignition and lock the car. Try unlocking and starting again, but nothing apart from the wipers going mad, the dash all lit up and all sorts of faults on idrive.
Called the AA and when the recovery guy turned up, he put the key in and everything was back to normal! We decided it was best to recover the car to the services at J30 and then get it checked out. When we got to the services a technician turned up, had a check over the car and could find nothing wrong. Scanned it for codes and there was just about every fault code going, which we both agreed probably just came up as a result of the car completely shitting itself and so as a result 99.9% of them would be red herrings. He cleared the codes and off i went. Missed my appointment so drove home. Car didn't miss a beat on the way home!

Scanned the car this morning to see if there are any new codes and the only ones I have are these, which checking through the history have been around for a long long time.
I'm wondering if the problem could be down to the battery. Had a look at it and it's still looks like an original bmw one. If that's the case its over ten years old now! Is there any way I can check using Carly when the battery was last replaced?
