Diagnose
Before Parts.
Modern vehicle faults are often connected across sensors, wiring, control modules and communication networks. We use a structured diagnostic process to identify evidence, test the affected system and narrow down the underlying cause before recommending the next step.

Service FAQ.
Is a fault-code scan the same as electrical diagnosis?+
No. Fault codes are useful evidence, but they do not always identify the failed part. Diagnosis may also require circuit, signal, power-supply and communication testing.
Can you investigate intermittent faults?+
Yes, although intermittent problems can require additional testing time or the right operating conditions before the fault can be reproduced and measured.
Do you cover vehicles outside Taunton?+
The workshop is in Bishops Hull, Taunton, and customers are welcome from across Somerset. Vehicle compatibility is confirmed before booking.
