Hi, My Father picked up a s420 last year w/35,ooo miles on it. Last time he drove it, it ran great, That was a month ago,Today,he got in and the batt was dead . He jumped it , got it started and now it the rpm quickly surges and when you step on the accelarator, it will not respond ! The BAS-ASR light is on,and the dash displays a wrench with the number -730 ? if anybody could shed some light, I would appreciate it !
I guess he wont be driving it to my house on Thanksgiving!
Happy Turkey day ! Thanks, J
