Booked my car for an MOT. Told it needed a new headlamp assembly due to" melted rear retainer, obviously incorrect". Quoted price £300 to pass retest. Took it home and looked for problem, could not see anything melted or wrong on either headlamp assembly. Next day took it to another registered MOT centre for 2nd opinion. Mechanic checked the ROSA/MOT fail report online and looked at assembly, took him 5 minutes to click the bulb into place as it had come loose. Said car will now pass and should not have been failed. Called manager at Halfords asked again if he thought car needed new assembly to pass he said yes. Told him about 2nd report...went quiet on phone. Booked into Halfords for retest. Car passed in ten minutes. I've made my mind up want went on maybe other drivers need to make their mind's up.
