What the reviews say

• E65 730d owners praise its comfort and report high overall satisfaction, but recommend a well-maintained example rather than a cheaper car with existing problems.[2][4]BMW 7 Series E65/E66
• Views on E65 730d running costs differ: one long-term owner calls them very low, while another warns of large workshop bills.[4]one sourceBMW 7 Series E65/E66
• The tested 730d xDrive suppressed noise and vibration, its air suspension controlled body movement well, and the 3.0-litre diesel with its quick gearbox delivered strong performance.[5]one source

Typical faults

• A 2010 F01 730d developed a hydraulic-fluid leak. Drips remained after two pump replacements, leading the owner to suspect a hose connected to the pump.[1]one source

  2010–2010 · 730d

• A 2010 F01 730d had a knocking noise over gentle undulations from 50,000 km. Replacing the stabiliser, arm bushes and both front dampers did not cure it; the cause remained unresolved.[1]one source

  50 000–50 000 km · 2010–2010 · 730d

• The owner of a 2005 E65 730d experienced several electronic faults early on; over longer ownership, a failed alternator and one injector also required replacement.[4]one sourceBMW 7 Series E65/E66

  2005–2005 · 730d

• An E38 730d repeatedly stalled while driving, became difficult to start and logged injection and low-pressure faults. It occurred more often with 20–30 litres in the tank, but the exact cause was not confirmed.[3]one sourceBMW 7 Series E38

Which engine and version to take

• For the E65, one review calls the 3.0-litre diesel the most rational choice, with sufficient power and reasonable fuel consumption.[4]one sourceBMW 7 Series E65/E66
• The newer tested 730d xDrive used a 3.0-litre diesel producing 286 hp and 650 Nm; the reviewer highlighted forceful acceleration and immediate response even in Comfort mode.[5]one source

What to check at the inspection

• On an F01 test drive, listen for knocking over gentle undulations. Check steering play and the rack too, as another contributor traced a similar noise to rack play.[1]one source
• Remove the F01 undertray and inspect the hydraulic pump and connected hoses; on the reported car, the drips became visible only after the cover was removed.[1]one source
• Diagnose an E38 730d and check fuel pre-supply and rail pressure. Test it with a lower fuel level too, because the reported stalling occurred more often with 20–30 litres remaining.[3]one sourceBMW 7 Series E38
• On an E65, test all electronics, the charging system and engine operation. One long-term owner reported early electronic faults, an alternator failure and one injector replacement.[4]one sourceBMW 7 Series E65/E66
