Dealer-level BMW care, without dealer prices.

What is the difference between a BMW CBS oil service and a vehicle inspection?

CBS (Condition Based Service) splits work into an oil service and a vehicle inspection rather than a fixed Service A / Service B letter. The oil service is typically annual (or around 10,000–15,000 miles) and covers oil, oil filter, cabin filter where due, fluid check and an ISTA CBS reset. The inspection is the longer check — often around two years depending on how the car is driven — and adds brake fluid, air filter, spark plugs on petrol cars and a longer inspection list.

How much does a BMW service cost in London?

At our London workshop, a CBS oil service starts from £249 and a vehicle inspection from £349, depending on model and engine. We send a fixed-price quote before any work begins.

Will an independent service affect my BMW warranty?

No. Under EU Block Exemption Regulation, independent servicing does not void your manufacturer or approved-used warranty as long as it is done to the BMW CBS schedule with the correct LL-01 / LL-04 oils and parts — which is exactly how we work.

What happens if I skip a BMW service?

Skipping services — particularly gearbox fluid, brake fluid and Longlife oil changes — is the single most common cause of expensive repairs on modern BMWs. The engineering margins are tight. We recommend sticking to the CBS schedule.

How much do BMW diagnostics cost?

Our standard diagnostic charge is £85 inc. VAT, which includes a full ISTA / Rheingold scan across every control unit, live data analysis and a written report. We credit the charge against any repair we carry out.

Is a generic OBD2 scan the same as ISTA diagnostics?

No. An OBD2 scanner only reads emissions-related faults. A modern BMW has dozens of control units. ISTA / Rheingold reads all of them, runs live data, actuates components on demand and does coding and programming — the same as a main dealer.
