Final OBD
Plug in one of those cheap OBD adapters and Final OBD reads every control unit in your car: what’s wrong, what data it gives and how the engine, turbo, battery or injectors are doing. All explained in plain words.
Go straight to your thing
Everyone comes to Final OBD for something different. Pick yours and we’ll show you with the app’s own screens.
No adapter yet
The app comes with a Škoda Karoq 2.0 TDI from one of our testers built in: what its 20 control units said on a real drive. Tap Demo at the top of the menu and you’ll see Your car moving, its faults, the ITV (the Spanish MOT) and the Cockpit, as if you had it plugged in.
You don’t need an adapter or a car, and nothing gets saved. Whenever you like, tap Exit the demo and connect your own.
Cylinders, one by one
The control unit knows a lot about each cylinder and hardly anyone shows it to you. Final OBD draws it as an X-ray so you can see which one is off.
What the control unit adds to or takes away from each injector so they all push the same. If one is correcting a lot more than the others, that injector needs looking at.
When the air-fuel mixture goes off too early, the control unit retards the spark on that cylinder. Here you see how many degrees on each one.
The cylinder that doesn’t push when it should. They’re counted one by one, and you can reset the counter to zero to see if it comes back.
Faults and ITV
Final OBD reads the faults in every control unit, not just the engine one, and shows you in colours what’s failing right now and what’s history. Once you’ve fixed it, you clear them.
And in Inspection monitors you can see whether the emissions tests have been done, one by one, with the kilometres since the last time faults were cleared. If someone cleared the faults yesterday, it shows here. (In the UK, a lit engine warning light is a fail at the MOT too.)
Buying a used car
With the engine running, the Buy or sell report reads the faults in every control unit, the Inspection monitors, the kilometres each control unit keeps on its own and all the car’s data. You get a PDF with a seal and a code.
Anyone can check the code and the QR at finalobd.com: if someone changes a single comma in the PDF, it shows. For the seller, it’s the way to prove the car is fine.
Your car
Engine, turbo, fuel, gearbox, battery, climate, servicing or traction: what each control unit gives, in its place and in real time. If you don’t know what something is, tap it and it explains.

Help
If you don’t understand what your car is telling you, there are two kinds of help inside the app. Both look at your car’s real data, not some generic manual.
Fault codes
Type in the code your adapter or your garage gave you. If it’s a standard one, we’ll take you to its page. If it’s specific to your make, pick the make.
Standard codes (P0, P2, the standard P3 codes, U0, B0 and C0) each have their own page, open to everyone. Manufacturer codes are looked up one at a time, up to 20 a day, and we only show the ones we’ve seen on real cars or that match across several sources.
Learn some mechanics
Our mechanics guide explains how every system in the car works, from the turbo to the hybrid battery, with X-ray drawings and no jargon. So when the app tells you something, you know what it’s on about.
