## Caption

We sent our BMW 1M Coupe (34,000 miles) to @PrecisionSportIndustries  (PSI) for a proper deep-dive inspection before we take the next step: installing a rare Akrapovič titanium exhaust.

In this video,  you’ll see PSI’s technician team do what they do best—start with a test drive, then put the 1M up on the lift for a full post-purchase-style evaluation. And yes… even a low-mile “dream car” can hide issues, especially when it’s lived through winters or spent time sitting.

What PSI found / what’s getting addressed:
 • Differential input shaft leak → diff replacement/rebuild plan
 • Oil pan gasket seepage
 • Aging factory charge pipe (classic N54 weak point)
 • Brake fluid condition → full brake flush (DOT 4)
 • Coolant flush + oil service
 • Outer tie rods so the alignment can actually be adjusted correctly (rust/binding)

The PSI team also does a walk around to check panel gaps, rubber condition, OEM glass, paint,  wheel condition and more. 

👉 Next episode: PSI installs the Akrapovič titanium rear muffler (with OEM mid-pipe) and we finish the repair list.
