Buy-risk rundown

Issue	Symptom	How to check	Typical cost (as of Nov 2026)
S65 rod bearings	Often none until failure; catastrophic crank/block damage	Treat undocumented bearings as due; oil analysis is supportive not definitive	Shop jobs commonly ~$2,000–$3,200; UK guides cite ~£1,000–£1,500 [1][2]
Throttle actuators (plastic gears / boards)	Sudden limp mode; codes 2B21/2B25/CDC0	Scan every service; replace both banks together	Dealer jobs can top $3,000; upgraded rebuilds are the enthusiast path [3][4]
Injectors sticking open (reported)	Misfire; hydrolock risk	Ask about injector history on problem cars	Not yet verified as a routine interval job [2]
DCT sump gasket leaks / fluid service	Wet sump; shift quality	Confirm fluid/filter service on DCT cars	DCT so far generally robust if serviced [2]

Notes

E90 sedan, E92 coupe, and E93 convertible share the S65 checklist.
Manuals skip DCT fluid drama; still need bearings and actuators.
