•Verify DVSA recall completion for EGR cooler fire risk using the vehicle VIN before any purchase
•Check current status of the Customer Care Package (fuel injector / crankcase ventilation) with a BMW dealer using the VIN
•Perform a cold start test and watch for blue smoke indicating failed valve stem seals
•Check oil level and ask for oil consumption history, more than 0.5L per 1,000 km is a red flag
•Request full service history and confirm oil changes were done at no more than 8,000-10,000 km intervals with correct BMW LL-01 spec oil
•Connect a BMW-specific diagnostic tool (ISTA or equivalent) and check for timing chain deviation codes and EGR fault codes
•Inspect all hoses, vacuum lines and wiring in the engine V for heat cracking, brittleness or insulation damage
•Smell test the engine bay warm for fuel odour, and check for staining under the intake manifold in the V

Timing Chain & Tensioners (both banks)
Inspect per BMW SI B11 16 14 bulletin, replace proactively if chain slack or rattle present
80,000-120,000 km
Valve Stem Seals (all 32)
Monitor oil consumption closely; replace if consuming more than 0.5L per 1,000 km
60,000-100,000 km
Fuel Injectors and Crankcase Ventilation Valve
Confirm Customer Care Package coverage and completion status; inspect for fuel or oil pooling in lower engine bay
60,000-120,000 km
EGR Cooler
Confirm DVSA recall has been completed, replace if coolant loss or codes present
50,000-100,000 km
Engine Bay Heat-Exposed Hoses & Gaskets
Full inspection and preventive replacement of cracked or hardened hoses in the hot-vee zone
80,000-120,000 km

EGR Cooler / Intake Manifold
Glycol leak from EGR system can cause intake manifold leak with potential fire risk. Affects vehicles built 2013-2018.
Fuel Injector / Crankcase Ventilation (Customer Care Package)
Leaking fuel injectors combined with a crankcase ventilation fault could allow fuel and oil to pool in the lower engine area, creating a fire risk. BMW extended component warranty coverage (10 years/120,000 miles in the US) for injectors, VANOS solenoids, crankcase ventilation valve and battery cable routing on affected N63 vehicles.

Do not choose between these two based on the small hp difference, the failure modes (valve stem seals, timing chain, injector seals) are identical across both tunes. The later N63TU2 cars are worth favouring mainly because a higher proportion of them were built after the Customer Care Package and EGR recall were rolled out at the factory, so documented completion is more likely. Always ask for the engine build date and confirm recall and Customer Care Package status by VIN rather than relying on the advertised power figure.
