A BMW Master Technician with 10 years of insider knowledge built the app that tells you exactly what dealers and shops don't want you to know — before you hand over your keys.
Brake fluid "failing," filters "critical," fluids "contaminated" — these are scripted upsells. A real tech knows the actual service intervals.
Shops replace parts hoping something sticks. Without proper BMW ISTA+ diagnostics, they guess — and you pay for every wrong guess.
Known software faults, technical service bulletins, and recall-adjacent failures get billed to owners instead of BMW NA when advisors are lazy or commission-hungry.
Shops charge book time when the actual job takes 30% less. You have no way to know — unless you've done the job yourself hundreds of times.
RevGuard puts 10 years of BMW master technician knowledge in your hands before, during, and after every service visit. Know what's real, what's bogus, and exactly what to say.
