BMW 335i / 340i service Melbourne.
Independent specialist. Dealer-grade. Warranty-safe.

The E90/E92 335i introduced the N54 twin-turbo inline-six — the engine that made BMW tuning what it is today. Enormous headroom on stock internals (600+ hp is possible on port-injection retrofits), a well-understood HPFP and injector story, and walnut-blast intervals that are non-negotiable around 80–120k km. A well-maintained N54 is one of the great engines. A neglected N54 is a warning tale.

The F30 335i switched to N55 — single-turbo, cleaner emissions, and a plastic charge pipe that fails predictably. We fit aluminium as a preventive job. F30 340i introduced B58 — arguably the best mass-produced petrol engine of the last decade. Cooling and ZF 8HP fluid discipline is the whole story.

The G20 340i continues B58 with further updates. Same maintenance profile — respect the ZF 8HP fluid interval, keep the cooling healthy, and the platform will run to 300k km without drama. Stage 1 flash on any of these three engines is transformative and safe when calibrated properly on 98 or E-blend.

Send your rego or VIN through the quote form or call 0483 939 216. We look up the exact build spec of your BMW 335i / 340i, come back with a written, line-itemised quote — usually same business day. No surprises after the fact.

Drop the car in the morning, or book a few days ahead. On arrival we run a full dealer-level diagnostic scan first — every module, stored and pending faults, freeze-frame data — before any spanner touches the car. Anything beyond the original job gets photographed, quoted in writing, and only proceeds with your written approval.

You leave with a stamped log book where applicable, a completed service and inspection sheet, and a plain-English summary of what we did and what to expect at the next interval. Every part fitted is line-itemised, and every fluid is manufacturer-spec.

An independent workshop like Apex works on a BMW 335i / 340i with the same dealer-level tooling (ISTA, ODIS, Xentry, PIWIS), the same manufacturer-spec fluids and the same OEM or manufacturer-approved parts. Under Australian Consumer Law, using a qualified independent workshop for factory-spec service preserves your statutory warranty.

The other difference is attention. At the dealer, your car is one of forty that day. Here it's one of six. That's why we have time to photograph findings on the hoist, log the diagnostic scan properly, and actually explain what we found rather than handing you a printout with a total at the bottom.
