Question 1

How much does car electrical fault diagnosis cost in North London?

Accepted Answer

MnF Motors charges from £60 for a full electrical fault diagnosis. This covers a proper multi-system diagnostic scan, live-data analysis, root-cause identification, and a written report of findings. There are no hidden extras.

Question 2

Will you just clear the fault code or actually fix it?

Accepted Answer

We never clear a code without understanding what caused it. Our diagnosis identifies the actual root cause — wiring fault, failed sensor, corroded connector, or ECU issue — before any repair work begins. Clearing codes without diagnosis is exactly what we advise against.

Question 3

What makes and models do you diagnose?

Accepted Answer

We diagnose any make and any model — European, Japanese, Korean, and American vehicles. Our diagnostic equipment covers the full range of OBD protocols, manufacturer-specific systems, and pre-OBD vehicles.

Question 4

Do I need to book in advance for an electrical diagnosis in North London?

Accepted Answer

We recommend booking ahead to guarantee a same-day or next-day slot. Call us on 020 8803 1231 and we will find the earliest available appointment. We serve all of North London from our Edmonton N18 base.

Question 5

Is the diagnosis fee deducted from the repair cost?

Accepted Answer

In most cases, yes. When you proceed with a repair at MnF Motors following a diagnosis, the diagnostic fee is offset against the total repair cost. Ask us when you book and we will confirm the arrangement for your specific job.
