Here we go again more testimonials from happy customers

We always like to publish our testimonials when customers have been happy with our vehicle services carried out from our garage pictured below.

With that said, here we go again. Here is a testimonial emailed to us just this morning from a happy customer.


“I would like to thank you all once again for the great work you did in repairing the ECU off my 1991 Lexus Soarer. Without you I would have had little option but to scrap the car as it was undriveable with a defective ECU.

I would thoroughly recommend you to anyone who requires such work and I am sure that all your other work is carried out to a similar high standard. Your Customer Service is excellent – I only wish that other companies I have dealt with in the past could have been the same.

I will certainly contact you again in the future as I am certain I will require more work to be done on my Lexus and the other cars that I own.”

We care about our customers at A1 Diagnostics, it would be easy to say to the customer the ECU is not repairable leaving Nigel with the only option but to purchase a new car. Buying a new car can dent the wallet slightly. We always say there is no job too big or too complicated for us especially when it comes to ECU repairs. We have a dedicated electrical bay to deal with the most complicated ECU problems.

If you are unsure what an ECU is here is a quick description. ECU stands for Engine Control Unit. The ECU is responsible for the management of the vehicle engine from fuel distribution, ignition timing and more engine related settings. If the ECU becomes faulty the engine that runs the car will not function and the car will come to a standstill.

For example, if the ECU circuitry becomes faulty or any of the board components like resistors, capacitors and diodes burn out then this will cause the ECU to stop working. The photos below show circuitry that had become faulty in the ECU of the Lexus Soarer also pictured below. We repaired the circuitry in our electrical bay which led to the ECU communicating correctly with the engine once again.

We gain testimonials because we go above and beyond for our customers. It doesn’t matter how big or small or complicated a job is we will get you back out on the road at the best and most affordable prices. If you would like to visit our garage get in touch and we will show you our high tech electrical bay pictured below where we repair hundreds of ECU’s every year.
