Question 1

Why does my car cut out intermittently while driving in Barnet?

Accepted Answer

The most common causes are a failing crankshaft position sensor, damaged or corroded wiring, a poor earth connection, a faulty fuel pump relay, or an ECU fault. Because the problem is intermittent, it requires live-data diagnosis while the fault is active — not just a standard fault-code read.

Question 2

How much does electrical fault diagnosis cost in Barnet?

Accepted Answer

MnF Motors charges a transparent diagnostic fee that covers the time needed to reproduce and capture the fault with live data. We will always give you a clear written quote for any repair before work begins. Call 020 8803 1231 for current pricing.

Question 3

Is it safe to keep driving if my car keeps cutting out?

Accepted Answer

No. A car that cuts out while moving is a serious safety risk — to you, your passengers and other road users. If the engine stalls at speed you lose power steering and braking assistance. Get it diagnosed as soon as possible.

Question 4

Will a standard OBD code reader find the fault?

Accepted Answer

Rarely — and certainly not reliably. Intermittent faults often leave no stored code at all. What is needed is live-data streaming from the ECU while the fault is actively occurring, so the technician can see exactly which sensor or circuit is dropping out.
