Here at Thomas + Davies in Merthyr Tydfil, we offer fixed prices on the ten most common repairs, including brake pads, front windscreen wiper blades, clutch and brake fluid replacement. So get in touch with us for all your Citroën needs, no matter how big or small.

Just as each Citroën model has its own personality, they also have their own servicing schedule. We can help you understand your vehicle's recommended schedule, and we will always use Original and Approved Citroën parts when the time comes for your car or van to be serviced.

Once your car or van reaches three years old, it will need an annual MOT. No one knows your Citroën quite like we do, so book your MOT with us and have the peace of mind that your vehicle is being taken care of by an experienced, DVSA accredited Citroën technician. We'll even clean your car while it's with us.

Your timing belt is in constant use and becomes worn over time. If your timing belt fails, it can cause serious damage and even engine breakdown.If you reach 50,000 miles and haven't had your timing belt checked, contact us and we'll take a look at it for your peace of mind.

Keeping your engine oil topped up is also important, but you must use the correct grade of oil for your car. By choosing Citroën for your servicing, we'll replace your oil with the exact grade needed for your vehicle.

Comfort is an important part of any journey, so we advise keeping your air conditioning system fresh and clean with regular checks and maintenance.You can also help preserve the comfortable atmosphere in your Citroën by maintaining the cabin and pollen filters.

Another filter that must be kept in good condition is the diesel particulate filter (DPF), which is fitted to all Citroën diesel engines as standard. This filters out carbon particles before they leave the exhaust system, which are then burned off when driving at higher speeds. If the filter starts to clog, you'll see a message or light on the dashboard, and this usually means you simply need to go for a longer drive at higher speeds (on the motorway for example). However, if the filter becomes clogged, you may need to give us a call to clear it for you.


Every Citroën has its own servicing schedule, which varies depending on the model and engine you drive
. In your vehicle’s handbook, you’ll be able to find how often you should take your car in for its service, as well as when specific parts should be replaced. Items like spark plugs, oil filters and pollen filters need regular checks and maintenance.
