BMW Z4 servicing & repair

BMW's two-seat roadster deserves specialist care. We service and repair all three Z4 generations — E85/E86, E89 and G29 — with the time-based attention a weekend car really needs.

GENERATION BY GENERATION

What we look for on yours

Each Z4 generation has its own patterns — and on low-mileage cars, time-related checks matter as much as mileage ones. We know exactly what to look for.

G29
2019 — 2026 · incl. M40i
The final Z4 returned to a fabric roof and shares its platform with Toyota's Supra. B48 four-cylinder and B58 M40i six-cylinder engines have proved impressively dependable.
COMMON CHECKPOINTS
•Coolant level & hose condition on B48/B58 engines
•Soft-top drains cleared & mechanism lubricated
•Battery health tested — weekend cars sit and drain
•Tyre age & flat-spotting on low-mileage cars
E89
2009 — 2016 · folding hardtop
The only Z4 with a folding metal hardtop, and the widest engine spread — from N52 straight-sixes to turbocharged N20 fours and the twin-turbo N54 35i.
COMMON CHECKPOINTS
•Hardtop microswitches, sensors & roof drains
•N20 timing chain & guide wear on pre-2015 cars
•N54 injectors, HPFP & wastegate rattle diagnosis
•Oil filter housing & rocker cover leak checks
E85 / E86
2002 — 2008 · roadster & coupé
The original modern Z4 — M54 straight-sixes, later N52 si models and the E86 coupé. Now a modern classic that rewards regular, unhurried care.
COMMON CHECKPOINTS
•Cooling system age: expansion tank, pump & stat
•M54 VANOS seal condition & rattle assessment
•Electric steering column checked for sticky feel
•Roof motor, microswitches & drains on soft tops
SERVICE INTERVALS

What your Z4 needs, and when

Most Z4s cover far fewer miles than a daily driver — so on this page, the time limits matter more than the mileages. Oil ages, brake fluid absorbs moisture and tyres crack long before the tread wears out.

Every Z4 is petrol, so the schedule is simple — whichever limit arrives first, time or miles.

Weekend car? We service to time as much as mileage — the kindest thing you can do for an engine that sits between drives.
