“Excellent Customer Assistance. I called the RAC out who diagnosed the body control module, this had become faulty on my Seat Altea 1.9tdi.

I had a serious electrical problem with indicators brake lights & main beam. Took my car to A1 diagnostics who again explained the problem.

A1 fixed it and I am truly thankful. Awesome service.”

“Had a problem with my MK7 Golf GTD yesterday that caused the car to go into limp mode. They managed to fit me in today and Iā€™m back on the road! Big thanks to the great mechanics who found that a wire had broken and fixed it.”

“I had my air conditioning on my Yaris serviced today, with a full diagnostic check and re-gas, excellent service, good honest help and advice throughout, at last my A.C. doesn’t smell like mouldy bread. Thank you so much A1 Diagnostics some honest people, who don’t rip you off because you are female. Definitely worth the drive from Bridgend.


The heatwave since it struck in June has made many motorists flock to garages to get their air conditioning serviced or fixed. Our theme for July has been about safeguarding motorists from cheap air conditioning services and deals made by other garages in Cardiff that are not fit for purpose.

If you want a decent service carried out on your air conditioning system you must make sure that the garage fully services the system. What we mean is, garages offering cheap air con deals normally just recharge the air con system, they do not check for leaks or pump out any bacteria in the system.

The problem with not checking for leaks is this, if there are leaks in the pipes and all a garage does is recharge the system then your air con system is not going to last, it will keep you cool for about a week and then before you know it you are back at the garage asking what happened.

At our garage we service the entire air conditioning system on your vehicle, we check for leaks and make sure the system is working from top to bottom, here is what is included in our service.

1) We check for leaks in the air con system.


2) We use high quality PAG oil to lubricate the compressor and pumps in your air con system.


3) We vacuum and remove the bacteria built up in your air con system over time.


4) We fully re-charge and gas refill the system if no leaks are found on test.



Here are some of our air conditioning service equipment and units we use, big investments by us to ensure we carry out the highest quality service for our customers.
