We are an award-winning independent garage. We have a dedicated engine department that offers all kinds of engine maintenance services. Whichever engine service you need we have got it covered!

In 2025 we have seen many vehicles coming in for wet belt and timing chain replacement services for vehicle brands such as Ford, Citroen and Peugeot. Here is a recent vehicle in the garage where we replaced the timing chain on a Land Rover vehicle.

Did you know that sometimes it is more cost effective to get the wet belt or timing chain replaced rather than replacing the entire engine or vehicle for that matter.
Sometimes garages say the engine is not repairable there for you need to scrap the car, but here at A1 Diagnostics we will completely strip the engine and get to the heart of the problem, fix the error and recondition the engine refitting it back on to the vehicle. This is far more cost affective than forking out money buying a new vehicle.
If the engine is not repairable, we can also source in a quality low mileage engine for your vehicle and fit it. This is also a far better option than going down the path of buying a new vehicle. We will make sure your vehicle is working as if you just bought it from the main dealer. Here is a photo of new engine being installed on a BMW vehicle.

It does not matter what the problem you are experiencing with your engine, we will get to the bottom of it. We are an award-winning independent garage that has over 20 years’ experience in the engine trade, there is nothing we have not seen before and have mechanics that have a combined 75 years’ experience in the trade. When you bring your vehicle to our garage it is in the safest of hands.
