Hi both, yes got the battery coded correctly and confirmed it is charging at right voltage now. Spoke to the electrician and he said it was not necessary to manually recharge at moment, went on a long journey (160 mile) and going back to electrician shortly per his request to run some tests just to make sure everything is still ok. No errors showed up and no issues in the journey so all good so far. And yes, apologies, I meant electrician rather than mechanic although he is an all rounder with 30+ years' experience. Just glad it wasn't anything major, hoping it stays that way :)

Quick update: car is back with me and so far so good. The garage could not pinpoint the issue as they did not have an electrical expert, fortunately managed to find a good mechanic after a lot of searching online. Main issue was oxidation in some of the connectors leading to increased resistance. A secondary issue (which may not have caused this issue but needed resolving) was battery charging at a lower voltage than it should due to battery adaptation not being updated when battery was changed.

Thanks for all the replies, car is still at the garage, unfortunately they could not look at it on Friday and were closed on weekend. Will post an update once diagnosed. One thing to re-emphasise, the first thing that happened on both occasions was the EPC light coming on, losing power and not being able to rev beyond 10k and then all warnings about lights coming on. Still hoping it's something small.

Hi all, Wondering if someone has experienced similar or can point to what may be the root cause. About a month a go, the EPC light came on and I started losing power, couldn’t rev above 10k then error after error started flashing up (Auto Start stop, tail light, brake light, every kind of light you can think of). Parked up, switched car off then tried switching back on it wouldn’t switch on. Long story short, recovery came, ran diagnostics and mentioned all errors including one about Fuel Rail/System Pressure low. However, by this time, after being off for about an hour, the car started fine. So recovery person cleared all errors, revved and ran some tests and said all looks fine, could’ve been a temp fault. Drove off no issues until last night. Same thing again but this time car wouldn’t start even after an hour. Recovery came again, same errors is diagnostics, battery was checked and all good on that side. Have dropped off to garage but hoping it’s nothing major (ECU issues? Fuel pump?).
