I'm running a 2011 BMW 335i xDrive with 6-speed Automatic transmission. I'm having thermostat stuck problems so, I figured I'd replace thermostat, water pump. Figured I'd do the GFB DV+ upgrade while I was down there. Also had a few diverter stuck codes, so I ordered an new piedmont diverter valve as well as the GFB DV+. No turbo upgrades or downpipes, just the JB4.
My question: Spring or no spring?
Are the troubles only with manual transmissions? Any worries with stock turbos & the spring?
Thanks a bunch,
Troy
