If you're looking for an MOT in Dunning, Bob's Mechanical Repairs in Birnam is just 22 miles away — around a 30 min drive. We're DVSA-approved, Class 4 cars and small vans, and we offer a free retest within 10 working days if something fails first time. Bob's 32 years on the tools means you get a straight answer on what your car needs — and what it doesn't.
Dunning drivers choose us because we're honest. We don't fail cars for the sake of it, we don't pad invoices, and we tell you when an advisory can safely wait. Bob and Nicole still run the workshop themselves — it's a proper family-run garage, not a chain.
Booking a service from Dunning? Interim, full and major services on all makes — oil and filter, multi-point inspection, brake check, fluid top-ups and a written report. A properly serviced car is far more likely to sail through its MOT first time, which is why most of our Dunning customers bundle the two together.
For Dunning drivers we strip down and inspect pads, discs, calipers, hoses and fluid quality every time. If something needs doing we tell you straight and quote you fair — quality parts, proper torque, guaranteed work. Brake faults are one of the top MOT failure reasons in Scotland; we'd rather catch them at service time than fail you on the day.
Slipping clutch, heavy pedal, juddering pull-away? Bring it in. We diagnose the full clutch system — pedal feel, hydraulics, release bearing, flywheel condition — and quote a fixed price for the job. We always inspect the flywheel on a clutch change; skipping that step is why some replacements fail again inside 12 months.
Engine management light on? Limp mode? Random electrical gremlin? We run dealer-level diagnostic scanners — fault codes, live data, actuator tests — and pinpoint the actual cause before quoting any work. Pre-MOT diagnostic scans for Dunning drivers regularly catch issues that would have failed the test, saving a wasted trip and a retest fee.
We see the same MOT fails come up again and again from Dunning drivers — bulbs out, wipers that smear instead of clear, tyres borderline on tread, and brake discs/pads on their way out. Suspension bushes and drop links wear quickly on the rural roads round here too. The upside: nearly all of these are quick, affordable fixes and we can usually sort them the same day.
Drop in from Dunning, we'll greet you by name, talk through what you need, and give you a realistic timing. Most MOTs are done in 45 minutes. If something fails we ring you with a clear, written quote before any work starts — no surprises.
We regularly serve drivers from Dunning and the surrounding area, with customers travelling in from Auchterarder, Perth, Crieff, Kinross, Muthill. 4.9 stars on Google from 180+ reviews — our reputation in Perthshire speaks for itself.
"Don't ignore a small advisory. The thing that's borderline today is the thing that fails you next year — and usually costs three times more by then." — Owen, Senior Mechanic
Check tyre pressures monthly, top up screenwash, and replace wiper blades when they smear — three two-minute jobs that prevent the most common MOT advisories.
We're based in Birnam, just off the A9 — easy to reach from Dunning (22 miles, about 30 min). We regularly look after cars from Dunning and surrounding villages including Auchterarder, Perth, Crieff.
22 miles via the A9 / local roads from Dunning. Plenty of parking on site, and we're easy to find — just look for the orange signage on Perth Road, Birnam (PH8 0DN).
Unlike the chains, we don't work on commission and we don't have a sales script. You get the same straight answer whether your car's a 10-year-old Corsa or a new SUV — what it needs, what it doesn't, and what it'll cost.

Dunning — straight from Bob
Living out in Dunning, you know fine well that your car isn't just a luxury—it's your lifeline. Whether you're commuting into Perth or navigating the narrow, muddy lanes around Strathearn, your suspension and tyres take a proper hammering. After 32 years on the tools, I’ve seen exactly what the Scottish winters and rural potholes do to a car’s underside. When it comes to your MOT, you don't want a 'pass at any cost' and you certainly don't want a fail for something trivial. I see a lot of Land Rover Freelanders and VW Tiguans from your way, and the grit on the back roads ruins the brake lines and coil springs faster than you’d believe. I’m here to give you a fair, honest test. If it fails, I’ll show you exactly why while the car is still up on the ramp, no jargon, just the cold hard facts and a fair price to fix it.
The faults I see most on Dunning cars
The B9141 and the back roads around Dunning are absolute killers for suspension. I see a lot of Nissan Qashqais (the 1.5 dCi models) coming in at the 60,000-mile mark with snapped front coil springs. You’ll hear a 'ping' like a guitar string, and that's an automatic MOT fail. Then there’s the ‘Strathearn Special’—corroded brake pipes. Because of the heavy salting on the roads between Dunning and Auchterarder, I’ve seen 2018-plate BMW 3 Series with rear brake pipes pitted to the point of being dangerous. Finally, there's the 'hidden' fail: rear leaf spring bushes on older Mitsubishi L200s or Navaras used for farm work. These get caked in mud which holds the moisture against the rubber, rotting them out. If I find a bush that's perished to the point of excessive play, you aren't going anywhere until I've pressed a new one in. These high-mileage workhorses take a beating in rural Perthshire, and the MOT tester's pry bar doesn't lie.
Honest mot testing pricing for Dunning
I’ll give it to you straight: a standard MOT is capped by the DVSA, but I usually charge around £45 to £50. If a main dealer in Perth is offering it for £19.99, be wary—they are looking for 'upsells' like a hawk. If your Astra J 1.4 turbo needs a new set of front pads and Pagid discs, you’re looking at about £180 to £220 with me. A main dealer will likely quote you £350 plus VAT for the same job using 'genuine' parts that often come out of the same factory. If you need a premium tyre because the Dunning bends have scrubbed your nearside front, a Michelin CrossClimate 2 might set you back £130, but it’ll last twice as long as a 'budget' ditch-finder costing £70. Don't spend £600 on an exhaust system for a 15-year-old Corsa; we can often weld a patch for £40 that’ll get you through two more MOTs.
What actually happens at the mot testing
An MOT is a minimum safety standard, not a guarantee the car is 'good' for a year. I’ve seen cars pass the MOT at 10 AM and the clutch give up at 2 PM—the test doesn't cover engine internals or clutch wear. What I look for are the 'hidden' fails that some fly-by-night garages ignore. For example, some places might miss a slightly frayed seatbelt or a flickering SRS (airbag) light, but I won't. It’s your life in that seat. A common 'pro' tip: check your tyre pressures before you arrive. If your TPMS light is on, it’s an automatic fail on any car registered after 2012. I’ve seen people spend £100 on diagnostic time for a sensor that just needed five minutes of air at the petrol station. Also, watch out for garages that 'recommend' mid-section exhaust replacements for a pinhole leak—a bit of Gun Gum or a neat weld is often all that's legally required to pass the leak test.
Getting to us from Dunning
The 22-mile run from Dunning is a decent stretch of road to get the engine up to temperature—which is actually better for the emissions test. You'll likely come via the A9 or the back road through Aberuthven. It’s a 30-minute drive, and I know that’s a trek when you’ve got work or kids to sort. That’s why I keep a couple of tidy little courtesy cars—usually a Skoda Fabia or a Toyota Yaris—ready for folks coming from out of town. Just let me know when you book. Most Dunning folk come to me because they’re tired of the 'retail park' garages in Perth treating them like a number. Here, you talk to the man who’s actually got his hands in your engine bay.
When to DIY and when to bring it in
If you’re handy with a spanner, there’s plenty you can do to prep for the MOT. You can definitely swap out your own bulbs—though on some modern Renaults or Audis, you practically have to take the bumper off, which is a nightmare on a gravel driveway. Replacing a pollen filter or an air filter is a 10-minute job with a screwdriver. But when it comes to things like pressing out a lower arm bush on a Ford Focus or bleeding the ABS block on a VW Golf, stop. Without a 2-post lift and a proper hydraulic press, you’ll end up rounded off bolts and a car stuck on axle stands. Anything involving the braking system hydraulics or sophisticated ECU diagnostics for emissions faults is where you should hand me the keys. I’ve got the Snap-On gear and thirty years of 'feel' that a YouTube video can't teach you.
Bob's tip
Here is a proper nugget for you: check your own screen wash and wiper blades before you bring it in. It sounds small, but if a blade has a tiny split or the bottle is empty, I legally have to fail the car. That’s a 'Fail' on your vehicle’s permanent history for the sake of a £10 set of Bosch blades and two minutes of your time. Also, if you’ve got a diesel with a DPF light that pops on and off, don’t just clear the code and hope for the best. Tell me. I’d rather take it for a proper 'Italian tune-up' down the dual carriageway to clear the soot levels properly before I hook it up to the emissions tester. It saves you a re-test fee and a lot of heartache.
