2 known faults with sources

Engines: XM / XM Label (4.4 V8) (Plug-in hybrid)

Applies if: Only if fitted with the automatic gearbox described in the record.

ZF 8HP oil level, leaks and harsh shiftsAutomatic gearbox

Engine / equipment: ZF 8HP automatic gearbox in rear-wheel-drive BMWs from 2009 (1 to 8 Series and X: F20, F30, F10, G20, G30, X3, X5…)
Period mentioned: 2009–2026
Symptoms: Harsh shifts (especially engaging D and 1st to 2nd), slipping or jerking; oil leaks from the pan, the mechatronic connector sleeve or the seals.
Possible cause described: BMW's diagnostic guide says an incorrect oil level is a frequent cause of shift complaints and asks for it to be checked every time, even with no visible leaks; the pan can be damaged by impacts. The sealing sleeve between gearbox and mechatronic lets oil through to the connector. The oil, sold as lifetime, degrades.
Check for the garage: Check the oil level with the official procedure (correct temperature and engine running), look for leaks at the pan, connector sleeve and seals, inspect the pan for impact damage and review adaptation values with ISTA.
Cost cited in the source: Oil change with pan and filter: maintenance; sleeve or seals: minor repair; mechatronic: expensive repairA rough figure from the original database, not an up-to-date quote.

Moisture or fogging inside the upper daytime running light of the headlights (BMW 7 Series G70, X7 facelift and XM)Lighting

Engine / equipment: BMW 7 Series (G70), X7 (G07) facelift and XM (G09)
Period mentioned: 2025 (US model years)
Symptoms: Moisture, condensation or fogging is visible inside one or both upper daytime running lights of the headlights.
Possible cause described: It can be water getting in through a housing sealing fault (a defect) or natural condensation from temperature and humidity changes, for example after a car wash (not a defect). BMW explains it in its SIB 63 11 23.
Check for the garage: Ask the workshop to check whether the headlight leaks: if it does, it is replaced; if it is natural condensation, a drying box is fitted where applicable.
