I finally obtained a copy of Eric J Ord's The Complete Sprinter Fault Code Guide Volume 1: 2000-2006. I was wondering if Scan Guage II code and the Eric's code are different. For example, I sometimes get P0675 code in SGII that is interpreted as glow plug issue. But when I look at Eric's code glow plug codes start from 1480 to 1482. I scan through entire book but couldn't find P0675. Any idea?
