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.
Who’s ready for the solar eclipse tonight? Has everybody got their welding mask ready? The second picture was taken through a welding mask during the previous partial eclipse—hopefully we’ll get another great view tonight!
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.
Auto technicians keep the world moving, yet they’re often overlooked when it comes to pay and recognition. Every day they diagnose faults, carry out complex repairs and keep millions of vehicles safe and on the road. Do you think auto technicians deserve higher wages, or are they paid fairly already?

This isn’t just an engine—it’s a look inside the engineering that made the Jaguar XJR such an icon. 🔍 The cutaway AJ16 4.0-litre supercharged inline-six reveals how everything works together, from the Eaton supercharger and timing chain to the pistons, crankshaft and valve train. It’s a rare opportunity to see the inner workings of one of Jaguar’s most recognisable performance engines. Which detail impressed you the most? 👇

Anyone else sick of faulty new parts? 🤦♂️

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? 👇
