Had to change the battery on my evo today, unfortunutally since doing so i have lost blue and me, steering wheel controls for b&m the whole shabang does anyone know how to reboot it, the cars a 60 plate but it has the newer b and me unit as my system broke so i got a 2011 module

Did the dealer not sort it while replacing the battery under Warrentee?

battery wasnt under warranty as they class as wear and tear

Wear and tear?.......A battery should last at least 3 years minimum.I would argue with dealer if it was me.You cant wear out a battery just by using the car for a couple of years!

How can a battery die in one year?! Not very good customer service from that dealer, granted the battery is not technically covered under warrenty but the B&M system shouldn't fail because of it.

Battery is covered for the first 2 years I thought

Try removing the negative fast removal post on the battery (black wire with black and red clip) for a couple of minutes then put back on
