Reading the fault is only the start

An engine management, ABS, airbag or other warning light means one of the car's control units has stored a fault. Plugging in a diagnostic tool tells you where to look. Finding the real cause, whether that is a sensor, a wiring fault or a mechanical problem, is the actual job.

As a rule of thumb, a red warning light means stop as soon as it is safe, and an amber one means get it checked soon.

Explained in plain English

Customers mention that Jay talks them through it. Mike M: takes his time to explain the issue and talks through the process throughout.

Not sure what is wrong? Send a WhatsApp describing it. A photo of the dashboard with the lights on, or a short video of the noise, helps a lot.

From fault to fix

Once the cause is found you get a price for the repair. Most jobs can be done in the same workshop: brakes, clutches and suspension, engine and electrical and hybrid batteries.

Jay is the best! I’ve used him several times for several different issues I’ve encountered. He’s very responsive, takes his time to explain the issue and talks through the process throughout. He recently repaired a thermostat/fan issue on my Vauxhall Astra and saved me a lot of money taking it to main dealer. Thanks again!
