Frequently Asked Questions

  • Where is Bob Kolln Automotive located?

    The workshop is based in Charmhaven on the Central Coast of New South Wales. Its location makes it a straightforward stop for customers travelling from Woongarrah, Gorokan, Wadalba, Toukley and Warnervale, without needing to head further afield to Gosford or Wyong.

  • Do you offer a pick-up and drop-off service?

    Yes. Vehicles can be collected and dropped off at Lake Haven Shopping Centre, giving customers time to shop, work or run errands while their car is serviced. This is arranged when the booking is made.

  • What makes and models do you service?

    The workshop services all makes and models, including everyday passenger vehicles, four-wheel drives and fleet vehicles. Whether a car is Japanese, European, American or Australian-built, the same servicing standards and parts sourcing apply.

  • Do you do 4x4 modifications?

    Yes. The team fits lift kits, snorkels and exhaust systems for four-wheel drives set up for touring, towing or off-road work. Any modification affecting suspension, axles or non-original components may require certification under New South Wales rules, and the workshop can advise on what's needed to keep a vehicle compliant and roadworthy.

  • Can you carry out logbook servicing without voiding my new car warranty?

    Yes. Under Australian Consumer Law, a manufacturer's warranty does not require servicing at a dealership. An independent workshop can stamp the logbook and carry out the service, provided the work follows the manufacturer's specifications and uses parts fit for purpose. Consumer group CHOICE has confirmed that the ACCC takes this position, and the Australian Automotive Aftermarket Association sets out the conditions that keep a warranty valid when using an independent repairer. Bob Kolln Automotive services vehicles to these standards, so logbook stamps hold up if a warranty claim is ever needed.

  • Which tyre brands do you stock?

    The workshop stocks Kumho, Kapsen, Goodyear and Dunlop tyres, covering a range of budgets and vehicle types. Staff can advise on the right tyre for daily driving, towing or off-road use, and fit tyres on the same visit as a service where possible.
