🚨 👈 That is our sensationalist headline klaxon, because the mainstream media is at it again. 📢
There's fresh headlines rolling out today: a new "undercover investigation" by diagnostics firm Carly claims UK garages are overcharging motorists by up to 5x for "simple" repairs, like an oxygen sensor.
Once again, garages are being dragged through the mud by a "rip-off" narrative that completely ignores the reality of modern vehicle repair.
In our latest feature, we break down exactly why this "mystery shop" is fundamentally flawed and what the mainstream press completely missed:
⚠️ Code reading vs. actual diagnostics: A £40 OBD dongle gives you a fault code; a professional technician gives you a cure. Testing wiring, checking the ECU, and finding the root cause takes highly skilled labor that an app simply can't replace.
⚠️ Parts quality: The £110 "expected standard" repair price strongly implies budget aftermarket parts, completely ignoring the cost of genuine OEM components that protect customers with long-term warranties.
⚠️ "Upselling" myth: What this report calls an "unnecessary upsell" (reporting dangerously thin brake pads during a sensor swap), professional mechanics call a legal and moral Duty of Care.
Modern workshops are investing heavily in ADAS calibration equipment, EV training, and essential software licensing just to keep their doors open. It is time we stop apologising for charging a rate that reflects professional expertise.
