My Cluster died on me I lost all illumination and then all power a day or two later. Sent it away to these guys. Instrument Cluster Repairs,bmw dvd navigation repair,Bhp Remapping, DPF Delete Removal , Airbag Crash Data Reset,Sat Nav Repairs, I posted it on Tuesday and received it back today (Friday), all fully working. £125 plus my initial postage and packaging. I've heard all sorts of horror stories, the dealerships charging £800 for a replacement. Apparantly this is a common fault with them. I got a free two year warranty too. Overall pleased with the service.
