HOW TO TELL IF YOUR CAR NEEDS A DIAGNOSTIC CHECK VS A FULL SERVICE

Book a diagnostic if a warning light is on, the car has a running fault, or a noise started suddenly. Book a service if the car is due on mileage or time, even if it feels fine. A service is scheduled maintenance. A diagnostic is fault-finding. Doing a service will not clear a stored ABS fault, and a scan will not change the oil.

Quick Answer
Book a diagnostic if a warning light is on, the car has a running fault, or a noise started suddenly. Book a service if the car is due on mileage or time, even if it feels fine. A service is scheduled maintenance. A diagnostic is fault-finding. Doing a service will not clear a stored ABS fault, and a scan will not change the oil.

Book a diagnostic

We scan the relevant modules, look at live data, and give you a written report. Then you decide whether to go ahead with the repair.

  • Any warning light that was not there last week
  • Misfire, loss of power, limp mode
  • Gearbox messages, 4WD messages, battery warnings
  • A new noise, smell or leak you cannot place

Book a service

A full service includes inspection. If we find a fault we will say so. That is not the same as starting with a diagnostic for a light that is already on.

  • Oil service or vehicle check due on the iDrive / dash
  • Twelve months or the mileage interval, whichever comes first
  • You want filters, inspection and a digital service entry

When you need both

Car is due a service and the engine light is on. We can scan it first, quote the repair, and do the service in the same visit if you want. Ask when you book.

Guide prices for both jobs are on the servicing page. We confirm against the registration.

QUESTIONS ON THIS TOPIC

Will a full service turn off my engine light?
Only if the cause was something the service actually fixes, such as a simple service reset. Most lights need a diagnostic.
Is a diagnostic the same as plugging in a code reader?
No. We read the right modules, check live data and report what the code actually means on that car.
Can I book a diagnostic at your Birmingham workshop?
Yes. Book online. Same-day slots are often available at B37.
