Pre-Purchase Inspection (PPI) - BMW
Description
A BMW pre-purchase inspection (PPI) is one of the most important steps before buying a used BMW. Since BMWs are performance-oriented vehicles with complex engineering, a thorough inspection helps uncover hidden issues that could be costly later.
What’s Included in a BMW Pre-Purchase Inspection
Diagnostic Scan
- Full computer scan with BMW-specific software (ISTA or equivalent)
- Check for hidden codes, adaptations, and shadow faults not visible on the dash
- Looks at modules like DME (engine), transmission, DSC (stability), iDrive, etc.
Engine & Drivetrain
- Oil leaks (valve cover gasket, oil filter housing, oil pan)
- Cooling system (water pump, thermostat, radiator, expansion tank)
- Turbo(s) or supercharger health (if applicable)

Why It’s Worth It
BMW M vehicles are reliable if maintained, but repairs can get expensive if deferred. A PPI can uncover $2K - $10K in upcoming repairs (cooling system, suspension, oil leaks, carbon buildup, etc.). this also gives you negotiating power - or tells you to walk away.
With over 20 years of hands-on experience with BMW //M models, we know these vehicles inside and out. Our expertise allows us to spot common issues early - helping you avoid costly mistakes down the road.
