We service and repair MGs of every age at our Birnam, Dunkeld workshop. The jobs we see most on MGs are zs ev and mg5 12v battery drain and infotainment and software faults, so we know where to look before the car is even on the ramp. Interim and full servicing follows MG's manufacturer schedule using supplier-verified parts, so cars still under warranty stay covered. Our diagnostic kit reads MG-specific fault codes properly rather than guessing at parts, and we carry out ECU remapping tuned for how the vehicle is actually driven. Book a service or MOT online, or call 01350 727 276 for a quote.

MG Service Intervals — What the Schedule Actually Says
MG petrol models are 10,000 miles or 12 months; the ZS EV and MG5 are 12 months or 15,000 miles with a heavier check every 2 years. MG's 7-year warranty stays valid with independent servicing to schedule. We service to the manufacturer schedule using supplier-verified parts, stamp your book, and record the work so your service history stands up when you come to sell. Every MG service includes all parts as listed, and anything extra we find is reported to you with a price before we touch it — no surprises on the bill.
Interim & Full MG Service Options
You can opt for a MG interim service or a MG major (full) service at our garage in Birnam, Dunkeld, Perthshire. An interim service is ideal if you cover high mileage or drive in demanding conditions — it covers the essentials like oil and filter change, fluid top-ups, and a safety inspection. A full service is more comprehensive and includes everything in the interim service plus spark plugs, air filter, fuel filter (diesel), brake inspection, and a thorough check of all mechanical components. Whichever you choose, our qualified technicians use the latest kit and equipment to carry out your MG mechanical repairs to the highest standard.
MG MOT Testing — Class 4
We are a DVSA-approved MOT testing station carrying out Class 4 MOT tests for all MG models. The MOT test checks that your MG meets road safety and environmental standards. If your MG needs an MOT, you can book online or call us on 01350 727 276. We'll send you a reminder when your MOT is due so you never miss a deadline. If your MG fails its MOT, we'll give you a clear, honest quote for the repairs needed and can often carry out the work the same day.
Common MG Faults We See in the Workshop
These are the MG problems that actually come through our doors, not a generic list. ZS EV and MG5 12V battery drain: On MG's EVs the small 12V battery causes most of the no-start and error-message complaints — it is rarely the traction battery. Infotainment and software faults: Screen freezes and connectivity dropouts are common and often fixed by a software update rather than hardware. Brake corrosion on EVs: Regenerative braking means the friction brakes are barely used, so discs pit and calipers seize. A classic MOT failure on a two-year-old EV. Suspension knocks on ZS and HS: Drop links and anti-roll bar bushes wear early on rough roads. When a warning light appears on your MG, our diagnostic kit reads live sensor data as well as fault codes, so we can tell the difference between a failing part and a sensor reporting one. That's how we avoid fitting parts that were never broken.
MG Brake Repairs & Replacement
Your MG's braking system is the most important safety feature on your car. We carry out all MG brake work including brake pads, brake discs, calipers, brake fluid changes, and handbrake adjustments. We only fit quality branded parts to your MG and always inspect the full braking system — not just the component you came in for. If your MG brakes are squealing, grinding, or the pedal feels soft, bring it in for a free brake check.
MG Engine Remapping & Tuning
Want more performance and better fuel economy from your MG? Our ECU remapping service can unlock the hidden potential in your MG's engine. We remap MG vehicles using OBD and BDM tuning methods to safely increase power, torque, and throttle response whilst also improving fuel economy. This is particularly effective on turbo-diesel MG models where savings of up to 20% on fuel are possible. Every MG remap is tailored to your specific vehicle and driving requirements.
MG Clutch, Timing Belt & Major Repairs
We handle all major mechanical repairs for MG vehicles. MG timing belt replacement is critical — if your MG's timing belt snaps it can cause catastrophic engine damage costing thousands to repair. We'll check your MG's service schedule and advise when the belt is due. We also carry out MG clutch replacement, dual mass flywheel repairs, turbo replacement, head gasket repairs, and suspension work. Whatever the job, we'll give you an honest quote before we start.
MG Owner's Manual & Service Schedules
Keeping track of your MG service schedule is essential for maintaining your car's value and reliability. Your MG owner's manual contains vital information about service intervals, warning light meanings, fuse box locations, tyre pressures, and fluid specifications. If you've lost your MG manual or want to check something quickly, you can view your MG owner's manual online for free at Car Manual All Makes — they have comprehensive manuals for all MG models including the ZS, HS, 3, 5, MG3, MG5, ZS EV.
Your MG Warranty Is Safe With Us
European Law changes effective 2003 mean that independent garages such as Bob's Mechanical Repairs are now able to service your vehicle with OEM parts (Original Equipment Manufactured). All services completed at Bob's Mechanical Repairs will not affect your MG manufacturer's warranty. Under the Block Exemption Regulation, you are legally entitled to have your MG serviced at any independent garage without voiding your warranty, provided we use genuine or equivalent quality parts — which we always do. This means you can enjoy main dealer quality service at independent garage prices.
Booking Your MG In — What to Expect
Tell us the model and roughly what it's doing and we can usually narrow it down before you arrive. On the ZS, HS, 3, 5 we already know the weak points, so a diagnostic slot is spent confirming a suspicion rather than starting from scratch. If it turns out to be one of the bigger jobs on this make — zs ev and mg5 12v battery drain; infotainment and software faults; brake corrosion on evs; suspension knocks on zs and hs — we'll price it in full, in writing, before anything is stripped down. Where a repair isn't worth the money on the age and condition of the car, we'll say that too. Ring 01350 727 276 or book online, and if you're not local to Birnam we'll tell you honestly whether the job is worth the trip.
