How long until LPG pays for itself?
Payback period based on your monthly mileage and fuel prices, plus the toroidal tank that fits your spare wheel well.
Recommended size 630/220 · net ≈ 42 L (80% fill). LPG consumption is assumed to be ~20% higher than petrol.
How much will a new tyre size throw off your speedometer?
Enter the original and new tyre size to see the diameter difference and your real speed.
Diameters: 652 mm → 660 mm. Within ±3%, generally fine.
Guide
What is an OBD2 fault code and how do you read it?
Almost every petrol car built after 2000 and every diesel built after 2004 has an OBD2 system. When the engine ECU reads an unexpected value from a sensor, it stores a five-character code and, if needed, turns on the check engine light on the dashboard.
To read the code, plug a diagnostic scanner into the 16-pin OBD socket under the steering wheel. With a Bluetooth ELM327 adapter and a phone app you can read engine codes yourself.
- P
- Powertrain: engine and transmission. Most codes on this site are in this group.
- B
- Body: airbags, climate control, seats, lighting.
- C
- Chassis: ABS, ESP, steering, suspension.
- U
- Network communication between control units (CAN bus).
If the first digit after the letter is 0, the code means the same on every make; if it is 1, it is manufacturer-specific. For example, P0171 means “system too lean” on every brand.
A steady light usually isn't an emergency; drive gently and have the code read at the first opportunity. A flashing light means the engine is misfiring badly; unburnt fuel can quickly melt the catalytic converter, so stop as soon as possible. Clearing the code doesn't fix the problem.
