Hello everyone, new member from Lancashire, UK. I drive a 2008 635D. Joined hoping to learn what I need and how to go about coding a new battery instead of paying Dealer prices. I've done quite a bit of spanner work on my car, removed swirl flaps, replace turbo hoses, replaced glow plug controller and glow plugs, exhaust pressure sensor, replaced thermostats and I have an Icarsoft BMII tool for code reading and clearing. Attached pics of my baby
