I came across this on well known Chinese website and I’ve spent the last 10 minutes trying to figure out how on earth it’s supposed to work. I’m still none the wiser! Can someone explain how this would actually work?

Would These 3D-Effect Number Plates PASS an MOT? 👀🚗 #MOT #Mechanic



You’re the MOT tester — pass or fail? 👀 These number plates have a 3D-style effect, but the characters themselves aren’t actually raised. So would you be happy passing this on an MOT, or is there something here that would make you fail it? Have a proper look before you decide and let me know PASS or FAIL in the comments.

Anyone else sick of faulty new parts? 🤦‍♂️

You fit a brand-new part expecting the problem to be sorted, only to find the new part is faulty and sends you straight back to square one. More wasted time, more diagnostics and an awkward conversation with the customer. Surely it’s happening more often now? Let me know your experiences in the comments.

Can you diagnose an engine fault just by reading the spark plugs? These four plugs came out of the same engine, but one stands out from the others. What do you think is causing it?

MOT testers, what are you giving this — pass or fail? We’ve got a yellow headlamp and an orange position lamp on the same vehicle. Both are working, but are those colours actually permitted under the MOT rules? Have your answer before I reveal the result.

Do You Give the Engine Bay a Quick Clean? 👀 #Mechanic #CarCare

When you’re working on a vehicle, do you give the under-bonnet area a quick clean before handing it back? We’re not talking about a full engine-bay valet—just wiping away the dust, dirt and any marks left while carrying out the job. Is it a professional finishing touch, or unnecessary extra work? Let us know what you do.

The live data doesn’t lie. These before-and-after captures from a 2012 Skoda Fabia show the difference a faulty exhaust gas temperature sensor can make. An unstable signal can lead to fault codes, poor diagnostics and unnecessary parts being replaced, while a steady temperature increase confirms the sensor is operating correctly. Always compare live data after a repair to make sure the fault has genuinely been resolved.

Does everyone keep a selection of “get me out of trouble” nuts and bolts? 🔩😅

You never know when one of these will save the day. Every workshop seems to have that box full of random fixings that somehow always comes in handy.

What’s the oldest or strangest save the day item in your collection? 👇
