BMW 7 Series Real Workshop Cases Malaysia — 4M Car Care
Real BMW 7 Series repair cases from our Bandar Sri Damansara workshop — engine, transmission, aircon and suspension.
Case 1: G11 730Li — Air Suspension + Battery (95,000 km)
G11 730Li came in with 'the car sits lower on the left front corner overnight.' ISTA confirmed air supply unit fault code + left front strut slow leak (3mm height difference left vs right after 8 hours). Also found battery SOH at 64% — insufficient for the car's module load. We replaced: left front air strut () + air supply unit compressor () + 105Ah AGM battery ( registered via ISTA). Total. Expensive but owner was relieved — car now sits level and starts reliably.
Case 2: F01 750Li N63 — Valve Cover Gaskets + Oil Level (110,000 km)
F01 750Li N63 with 110,000 km came in for a service. Owner mentioned 'oil smell in the cabin sometimes.' Inspection found both valve cover gaskets seeping (typical at this mileage on N63) and oil level 1.5L below minimum — owner had not been monitoring. We replaced both valve cover gaskets ( — two covers, access is complex on V8) and topped up oil. Advised owner to check oil level monthly — N63 can consume 0.5–1L per 5,000 km, which is within BMW's acceptable range but requires monitoring. Total.
