With the most comprehensive range of vehicle software solutions available we can fix any electrical fault on your vehicle.

As you may have noticed we are undergoing changes and diversifying our business over the last few months.  There are still alot of changes to happen and we believe it will improve the way your car is repaired with less down time.

My own field in this business has been from an electrical prospective, meaning that i see what other mechanics cannot.  Too often we hear of, “oh i`ve had my car on a computer”.  Having a computer is one thing using it is another!    Today`s vehicles are complex machines where having the knowledge and knowhow is a must.  Experiance and dedication have driven this passion to a degree where any vehicle can be diagnoised and repaired by logic.   After all someone had to design and build it!


Castlederg Auto Electrics are Ireland’s leading Diagnostic Specialist’s in the automotive industry. Formed in 2002 we have strived for excellence in repairing electrical faults to vehicles from all over Ireland, servicing over 300 smaller garages. Cars today contain many electrical systems which are linked together to form a complex communication system known as CAN bus. Too many times most garages assume that if you try a part, it may fix the problem, but at the customers expense. Here at Castlederg Auto Electrics by simply accessing the cars diagnostic system faults can be found and pin pointed exactly meaning that only the correct parts are supplied and fitted. This lowers the cost to the customer of a professionally repaired job.

Castlederg Auto Electrics are the only garage that specialise in complete diagnostics and electrical repairs with proper diagnostic tools and nothing else!

We have one of the largest collection of vehicle diagnostic equipment to serve any manufacturer and repair them as required.
