Calgary expert
 

My 08 E70 4.8 is going berserk. Limp mode sporadically occurs complete with wipers on! Is there an expert in diagnosis in Calgary? I have tried one indie, multiple forums, battery swaps, control units replaced, alternator, yaw sensor, the list goes on. Have foxwell n520, and bummer geeks protool, but need a real Sherlock! Thank you
