Question 1

Why has my pre collision assist warning light come on after a bumper repair in Southgate?

Accepted Answer

Your front radar sensor is almost certainly mounted to or directly behind the bumper. When a bodyshop removes and refits the bumper — even by a few millimetres — the radar's alignment changes. The car's safety computer detects the discrepancy and disables the pre collision assist system, triggering a fault. The fix is professional ADAS radar calibration, not a parts replacement.

Question 2

How much does ADAS Camera & Radar Calibration cost in Southgate?

Accepted Answer

At MnF Motors, ADAS camera and radar calibration for Southgate customers typically starts from around £95–£180 depending on your vehicle make and whether static or dynamic calibration is required. We provide a full written quote before any work begins — no hidden extras.

Question 3

Can I drive my car with the pre collision assist fault light on?

Accepted Answer

Yes, you can usually drive the vehicle, but your automatic emergency braking and forward collision warning systems will be disabled or reduced in capability. This means the car will not automatically brake to prevent a collision. We strongly advise getting the calibration completed as soon as possible.

Question 4

Will the pre collision assist fault cause an MOT failure in Southgate?

Accepted Answer

Currently, an illuminated ADAS or pre collision assist warning light does not automatically cause an MOT failure in the UK, but this is under active review by DVSA. More importantly, a miscalibrated radar sensor on vehicles where it affects steering or braking directly could result in a dangerous fault advisory. Get it sorted before your next MOT.

Question 5

Does the bodyshop have to recalibrate ADAS after a bumper repair?

Accepted Answer

Yes — any accredited bodyshop should recalibrate ADAS sensors after removing or replacing a front bumper. In practice, many independent bodyshops in and around Southgate do not have the specialist equipment to do this and simply return the car without recalibration. MnF Motors provides this service to bodyshops and private customers alike.
