We service and repair Porsches of every age at our Birnam, Dunkeld workshop. The jobs we see most on Porsches are coolant pipe and water pump failures and bore scoring on older flat-six engines, so we know where to look before the car is even on the ramp. Interim and full servicing follows Porsche's manufacturer schedule using supplier-verified parts, so cars still under warranty stay covered. Our diagnostic kit reads Porsche-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.
Porsche Servicing in Birnam, Dunkeld & Perthshire
Looking for a trusted Porsche garage in Perthshire? Bob's Mechanical Repairs provides expert servicing, MOT testing, diagnostics and repairs for all Porsche models. Whether you drive a Cayenne, Macan, Panamera, 911, 718 Boxster or any other Porsche, our experienced team has the skills and equipment to keep your car running at its best. We're conveniently located in Birnam, Dunkeld, and serve customers across Dunkeld, Birnam, Luncarty, Aberfeldy, Bankfoot, Perth, Blairgowrie, Pitlochry, Blair Atholl, Stanley.
Porsche Service Intervals — What the Schedule Actually Says
Porsche is generally 12,000 miles or 24 months on modern models, with brake fluid every 2 years and PDK fluid around every 40,000 miles. On cars that sit over winter, annual oil is the better call. 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 Porsche 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 Porsche Service Options
You can opt for a Porsche interim service or a Porsche 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 Porsche mechanical repairs to the highest standard.
Porsche MOT Testing — Class 4
We are a DVSA-approved MOT testing station carrying out Class 4 MOT tests for all Porsche models. The MOT test checks that your Porsche meets road safety and environmental standards. If your Porsche 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 Porsche 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 Porsche Faults We See in the Workshop
These are the Porsche problems that actually come through our doors, not a generic list. Coolant pipe and water pump failures: Cayenne V6 and V8 models leak from plastic coolant pipes and pump housings — often first noticed as a low coolant warning. Bore scoring on older flat-six engines: 996 and early 997 engines can score cylinder bores; a proper compression and borescope check before buying is money well spent. PDK gearbox fluid neglect: The PDK is durable but wants its fluid and filter on schedule; neglected boxes shift harshly and then get expensive. Air suspension leaks on Cayenne and Panamera: Struts perish and the compressor works itself to death maintaining pressure overnight. When a warning light appears on your Porsche, 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.
Porsche Brake Repairs & Replacement
Your Porsche's braking system is the most important safety feature on your car. We carry out all Porsche brake work including brake pads, brake discs, calipers, brake fluid changes, and handbrake adjustments. We only fit quality branded parts to your Porsche and always inspect the full braking system — not just the component you came in for. If your Porsche brakes are squealing, grinding, or the pedal feels soft, bring it in for a free brake check.
Porsche Engine Remapping & Tuning
Want more performance and better fuel economy from your Porsche? Our ECU remapping service can unlock the hidden potential in your Porsche's engine. We remap Porsche 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 Porsche models where savings of up to 20% on fuel are possible. Every Porsche remap is tailored to your specific vehicle and driving requirements.
Porsche Clutch, Timing Belt & Major Repairs
We handle all major mechanical repairs for Porsche vehicles. Porsche timing belt replacement is critical — if your Porsche's timing belt snaps it can cause catastrophic engine damage costing thousands to repair. We'll check your Porsche's service schedule and advise when the belt is due. We also carry out Porsche 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.
Porsche Owner's Manual & Service Schedules
Keeping track of your Porsche service schedule is essential for maintaining your car's value and reliability. Your Porsche 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 Porsche manual or want to check something quickly, you can view your Porsche owner's manual online for free at Car Manual All Makes — they have comprehensive manuals for all Porsche models including the Cayenne, Macan, Panamera, 911, 718 Boxster, 718 Cayman.
Your Porsche 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 Porsche manufacturer's warranty. Under the Block Exemption Regulation, you are legally entitled to have your Porsche 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 Porsche 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 Cayenne, Macan, Panamera, 911 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 — coolant pipe and water pump failures; bore scoring on older flat-six engines; pdk gearbox fluid neglect; air suspension leaks on cayenne and panamera — 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.
