Mr Auto Fixer — Professional UK Mechanic & MOT Tester
20+ Years Under the Bonnet
Hi, I'm Mr Auto Fixer — a professional UK mechanic and qualified MOT tester. I've spent more than 20 years working on cars and light commercial vehicles in independent UK workshops, from quick service jobs to full engine and gearbox rebuilds.
I created this site to put real, hands-on workshop knowledge in front of the drivers who need it most. Every guide on Mr Auto Fixer is based on a job I have personally completed. No guesswork. No copy-paste from a manual. Just the actual steps I follow, in the order I follow them — including the hidden bolts, the stubborn parts, and the mistakes that cost time and money the first time you do a job.
Qualified, Certified, On the Tools Every Week
I've spent my entire working life in the motor trade. After completing my mechanical training as a teenager, I went straight into independent workshops — the kind of garages that fix anything that's driven through the door, from a 20-year-old diesel hatchback to a four-year-old van that hasn't had a service since it left the dealer. That mix is where you learn how cars actually fail in the real world, not in a textbook.
Today I hold a valid UK MOT tester qualification, which means I am authorised by the DVSA to carry out the Class 4 MOT test on cars and light commercial vehicles. To stay licensed I complete the annual MOT assessment, sit refresher training, and keep my MOT tester profile up to date — so my knowledge of what fails an MOT (and why) is current, not stale.
Across my career I've worked on every major brand sold in the UK: Ford, Vauxhall, Volkswagen, Audi, BMW, Mini, Mercedes, Renault, Peugeot, Citroen, Nissan, Honda, Kia, Mazda, Suzuki, Skoda, Volvo, Land Rover, Fiat, MG and Mitsubishi. Petrol, diesel, hybrid and EV. Manual and automatic. Front, rear and four-wheel drive. That breadth is reflected in the makes covered on this site.
My qualifications cover:
UK-recognised mechanical training (Light Vehicle Maintenance & Repair, Level 2 and Level 3 equivalent route) · DVSA-approved MOT tester (Class 4) · Diagnostic equipment certified (OBD2/EOBD scan tools, multimeter, oscilloscope basics, smoke testing for evap and intake leak diagnosis) · Cambelt and timing chain replacement (multiple manufacturer-specific procedures) · Manufacturer technical bulletin and TIS reference for the makes covered.
Driven By What Drivers Get Wrong
The reason this site exists is simple. Every week I see drivers pay hundreds of pounds for jobs that take fifteen minutes and a £6 part — or worse, drive around on a fault that's about to turn into a £2,000 problem because nobody explained the warning signs in plain English. A pollen filter swap, a service light reset, a fault code that means “tighten the petrol cap” rather than “rebuild the engine.” Things you can do yourself, on your own driveway, if you know how.
I started filming jobs on my phone for friends and family and uploaded the first few to YouTube. The comments and questions that came in made it obvious there was a gap. There are plenty of American repair channels, plenty of dealer-style theory videos, but very little UK-specific content written by someone who has the car on the ramp every day, knows what parts cost at a UK factor, and understands what will and won't pass an MOT here. Mr Auto Fixer is my answer to that gap.
How a Guide Gets Published
Every guide on this site follows the same three-step process before it goes live:
1. Complete the job. I won't write a guide on a repair I haven't done. If I have not personally done the job on the exact make and model in the title, the guide does not get published. Where I have done the job on the same platform but a different model year, that's stated up front in the introduction.
2. Document the steps as they happen. The photos, torque values, tool sizes and tips come from the actual job — not from a workshop manual I've skimmed. If a step has a trick to it (a hidden clip, a bolt that needs heat, an order of removal that matters), it goes in the guide because I learned it the hard way.
3. Verify and update. Every guide has a “Last checked” date. When a manufacturer issues a technical service bulletin, a model gets a facelift that changes a procedure, or a reader writes in with a correction, the guide gets re-checked and the date gets updated. Content that's no longer accurate gets pulled, not patched.
I write everything personally. I do not use ghostwriters, generic content suppliers, or AI-generated fill. The voice you read on a Mr Auto Fixer guide is mine, talking the same way I'd talk to a customer in the workshop.
Important: All guides are for informational purposes and reflect the procedures used on the specific vehicles I have worked on. Always follow safe working practices, use correct tools, observe torque specifications, and consult your vehicle's official documentation where supplied. If in any doubt, take your vehicle to a qualified mechanic. Never work under a vehicle supported only by a jack — always use rated axle stands on a level surface.

Free Guides Written by a Real Mechanic
Mr Auto Fixer is a free car repair resource for UK drivers. Every guide is based on a job I've actually completed, often filmed as a YouTube video so you can watch the process as well as read it.
The guides cover everything from quick, no-tools jobs like pollen filter changes and service light resets, through to advanced work like cambelt replacements, gearbox removals, and driveshaft jobs. Each guide is rated for difficulty so you know exactly what you're taking on, and every page lists UK-realistic costs so you can decide whether DIY or a trip to the garage makes more sense for the job in front of you.
Premium PDF Guides
As well as the free guides, I've produced a range of premium PDF guides that go deeper into specific topics — from understanding OBD fault codes in plain English, to a full owner's bible for the Ford Transit Custom. All guides are written by me, UK-specific, and available as instant downloads.
