Yes, we can rebuild your engine, dismantle and put together your DSG gearbox and so many more complicated jobs. However, we can also put your vehicle through its full service and change the oil and filters on your vehicle. Below we have a Kia Sportage in the garage receiving a full service getting the oil and filters changed.

When should you bring your vehicle in for a full service?
It is important to bring your vehicle in normally every 12months for a full service or after driving 12,000 miles out on the road. During a full service we check all vehicle components included in the full service. An interim service would not include this however will get your oil and filters changed.
We advise that if you’re going to drive many miles on a trip it would be best to book in for a service. If the oil, you have in your vehicle is contaminated to the point where it is ineffective this can do more damage to your vehicle. The oil is like the blood of your vehicle without oil your vehicle would not work, the oil lubricates all the major components of the vehicle, which is why it is essential to have good oil running through the vehicle.
