Log Book Service Ashburton.
Independent. Specialist. Fair.

A manufacturer log book service isn't just an oil change. It's a defined interval — either kilometres or time — during which a specific list of items must be inspected, replaced, or renewed to keep the car in factory-approved mechanical condition. The list is different for every manufacturer, every engine and every model year.

BMW's Condition Based Service (CBS), Audi/VW's LongLife service interval, Mercedes-Benz's Service A/B and Porsche's fixed-interval schedule all define exactly what has to happen and when. We follow the actual factory schedule via dealer-level scan tools — ISTA, ODIS, Xentry, PIWIS — not a generic 'oil and filter every 10k km' regime.

Missing an item — deferred brake fluid, deferred coolant, deferred DSG service, deferred spark plugs — is how expensive later failures happen. We do the whole schedule, we photograph anything we find, and where applicable the physical service book is stamped. As an independent workshop we do not write to manufacturer-controlled digital service-history systems, so you also receive a completed service and inspection sheet, relevant photo and video evidence, and an itemised invoice.

For a period in the late 2000s and 2010s, several manufacturers marketed transmission fluid, coolant and even brake fluid as 'lifetime fill'. The field data disagrees. Every DSG, ZF 8HP and MCT we see with delayed shifts, judder or fault codes has either never had its fluid changed, or has been changed with the wrong spec.

Fluids degrade. Additive packages break down. Metal wear accumulates. Temperature cycling breaks the polymer chains that give the fluid its shear stability. A modern automatic gearbox is an expensive unit; the fluid service that protects it is a small fraction of that. The maths is not close.

• Engine oil

  5,000–15,000 km depending on manufacturer spec, driving pattern and fuel used. LongLife intervals only apply when the car has been driven within LongLife parameters.

• Brake fluid

  Every 2 years, without exception. Hygroscopic — absorbs water — and boils at a lower temperature over time. Non-negotiable.

• Coolant

  Manufacturer-specific — usually 4–7 years. Not 'lifetime'. Correct spec matters — VW G13, BMW HT-12, Mercedes MB 325.5.

• DSG / DCT / auto fluid

  60,000–100,000 km depending on unit. Every DSG in the workshop with problems has had its fluid ignored.

• Diff & transfer case

  Manufacturer interval, usually 60–100k km. Skipped on almost every used European car we see.

• Power steering / haldex

  Haldex controller (Quattro/4Motion) — 40k km. Almost universally skipped.

Under Australian Consumer Law, a manufacturer cannot void your statutory warranty because you serviced at an independent workshop — provided the service was performed to manufacturer specification, using approved parts, by qualified technicians. That is exactly the standard we work to.

We use manufacturer-spec fluids (VW 508.00, BMW LL-01/LL-04, Mercedes 229.5, Porsche C40) and OEM or reputable OE-quality parts that meet the required specification (Bosch, Mahle, NGK, Pierburg, ZF, LuK). Where applicable the physical service book is stamped, and every service is documented with a completed inspection sheet, relevant inspection evidence and an itemised invoice. When the car goes back to the dealer for a warranty claim, that documentation stands up.

The workshop is in Wantirna South, VIC 3152 — approximately 18 minutes from Ashburton (3147). Most clients drop the car in the morning and arrange their own transport back to work or home. Send your rego or VIN through the quote form or call 0483 939 216 — we come back with a written, line-itemised quote same business day.

Same-day work where possible. Anything requiring parts on order gets a realistic in-and-out timeline before you book. No 'we'll let you know' — you get a scheduled collection day.
