Fault finding before parts, cleaning or tuning.
A scan is a starting point, not the answer. PPG checks symptoms, fault history, live data and system behaviour before recommending the next step.
DPF & AdBlue
DPF warning lights, failed regeneration, pressure data, AdBlue countdowns and NOx faults.
Modules & CAN
Intermittent electrical faults, communication errors, body control issues and module-related warnings.

Diagnostics Bangor FAQs
Is the diagnostics work carried out in Bangor?
The diagnostic work is workshop-led from PPG in Newtownards so the vehicle can be checked properly with the correct equipment and test process.
Should I book diagnostics before remapping?
Yes if the car has warning lights, limp mode, smoke, DPF, AdBlue, boost or drivability problems.
Can a fault code tell me what part to buy?
Not reliably. A fault code gives direction, but live data and testing are needed to avoid replacing the wrong part.
