•Run the VIN through BMW's recall checker to confirm the EGR cooler recall has been completed
•Pressure test the entire cooling system to identify any turbo coolant line or EGR cooler leaks
•Connect an OBD-II scanner and check for stored or pending fault codes, especially boost and EGR related
•Inspect turbo coolant feed and return lines by hand for cracking, weeping or heat damage
•Verify oil service history, insist on stamps or invoices showing intervals no longer than 10,000 km
•Test drive with sustained acceleration to confirm no limp mode, unusual turbo lag, or hesitation under boost
•If buying an aftermarket intercooler equipped car, confirm the part is genuinely LCI-specific and correctly fitted

Do not pick a B38 based on the hp figure alone, all outputs use the same block, turbo, EGR cooler and coolant line hardware, so the known issues apply equally across 109, 136 and 140 hp versions. The only meaningful reliability difference is whether the EGR recall has actually been completed and whether the coolant lines have been inspected or replaced, not which power tune the car has.
