Does my X5 have an AGM battery?

[stevo6]

I have an 08 X5 3.0 SD (no stop/start) and can't work out for sure if I need an AGM battery or not. The current battery is a BMW with part number S 61 21 7 551 331 but there's nothing to say what type it is.

Anyone know??
Cheers

Shame about the bad news OP.

I had to buy an AGM one for my 2007 123d (with stop/start) after less than 6 years - cost was about £300 fitted once the OBD was told it had a new battery.

Bosch do decent agm batteries, still expensive but not as bad as the genuine one. From looking at the side by side, i would hazard a guess they came out of the same factory.
I get mine online from Tayna batteries.
You will need to get the ecu reset to acknowledge the new battery either diy with an inpa cable or via someone with diags.
