Hi all, My E220 CDi 2004 has a reduced braking..start engine warning in red when i unlock the car and this then disappears once the car is started. I can see from some posts that this could be a sbc pump failure, however the car drives and brakes perfectly normal as far as I can tell. My question is that could a low battery trigger this warning or is it better to just get it code read. Also if the pump has failed does anyone know the present cost of a replacement, used and new or whether or not they can be repaired. The car has covered 101K with FSH..dealer/indie Once again my thanks for all your help.
