What to do when a warning light comes on
A red warning light, such as oil pressure, coolant temperature or brakes, means stop as soon as it is safe and do not keep driving. An amber light, such as the engine management or DPF light, usually means the car can be driven carefully to us, but the fault should be checked soon before it causes more damage. A flashing engine light often means a misfire — reduce speed and get it looked at the same day.
How our diagnostic check works
We connect professional diagnostic equipment to your car, read the stored fault codes and look at live sensor data while the engine runs. A fault code points to the system with the problem, not always the exact part, so our technicians then test the components involved to find the real cause. You get a clear explanation and a price for the repair before any work is done.
Common faults we find on Bushey cars
Short trips around Bushey and Bushey Heath are hard on diesels, so DPF warnings and EGR valve faults are common. We also see a lot of misfires from worn coils and spark plugs, faulty sensors, and battery or charging warnings in colder months. Most of these are repaired the same day.
Bushey car diagnostics FAQs
Can you just clear the light? Not always. Clearing a code without fixing the cause just means the light comes back. We find and fix the cause first.
Will a warning light fail my MOT? Yes — an illuminated engine management light is an MOT failure, so it is worth diagnosing before your test.
