I just put a 95aH Varta in my N63 X5 but couldnt code 95aH - the only options were 90 or 105 - tried editing the trace file but ncsexpert flagged it so I just left it at 90 and registered via Ista+. Any experience trying to add a non-bmw battery of a rating not natively supported? Sorry if this thread is not appropriate to ask

I had the same issue. I just bought the 105ah AGM battery at the dealer. It was the same price ($200) as the lesser AH at the auto parts stores.

All US N63 engines now use the 105ah. https://static.nhtsa.gov/odi/tsbs/20...53642-9999.pdf
