Car hesitates and dies with hard brake pedal
Hi, I have 2002 M5 with 136,XXX miles and the car started to stall as I was driving. The car just died and the brake pedal went rock hard. I've searched the forums and it looks like an issue with the brake booster. Would that also cause issues with the throttle? I noticed last night that the throttle had a slight hesistation. I'm waiting for a tow now and will pull INPA codes when I get home. The car starts, but the engine is surging a bit and the brake pedal stays hard. Any ideas? Thanks
