Car diagnostics and warning lights in Stoke-on-Trent
A warning light doesn't tell you what's wrong. Our Bosch diagnostic equipment does. TGS Autos finds the fault first, explains it in plain English and quotes before any repair, at our Bosch Car Service centre on Dividy Road, ST2 0AH.

Amber or red?
An amber light usually means get it checked soon. A red light, or a flashing engine light, can mean stop safely and don't drive on. If you're not sure, send a photo of the dashboard on WhatsApp and we'll advise.
What happens next
We read the fault codes and test the system properly rather than guessing from a code alone. You'll get the findings and a price for the fix, and nothing goes ahead without your approval.

Questions
Is a code reader the same as a diagnostic?
No. A code points to the area of a fault; a diagnostic tests the system to find the actual cause, so you only pay for the repair you need.
Can you diagnose hybrids and EVs?
Yes. Our IMI-qualified technicians diagnose hybrid and electric vehicle systems, including high-voltage components.
Do you do ADAS calibration?
Yes. Driver-assistance cameras and sensors may need calibrating after a windscreen replacement, suspension work or an accident. Ask us to check your vehicle.
