OBD2 diagnostics for Citroën

What Final OBD reads and does on Citroën cars. The basics work on any car with OBD2; the rest depends on what each control unit answers, and here is what the app knows about the make and its 33 models.

What there is for Citroën

Figures for the whole make. On your car the app shows what its control units answer, no more and no less. The needle shows which version each feature is in.

Free
Gauges and engine faults
Standard OBD live data and engine faults explained, free with Free.
Pro
Faults from every control unit
Engine, gearbox, ABS, airbag, body and the rest, explained, with how the car was running when they happened, and cleared once fixed. 1,531 codes specific to the family, on top of the generic ones.
Pro
Roadworthiness verdict
What the Spanish ITV test centre reads through the OBD socket, judged by its official manual: pass, fail or something still to read.
Pro
Make specific data
904 readings that standard OBD doesn’t give and that the make stores its own way, depending on each model.
Pro
Mileage check
The mileage stored in the control units, next to the dashboard figure. If one of them holds more, it’s the classic sign of a clocked car.

Citroën models

Each model with its years and engines, and what can be done on it. A yes means the app has it for that model; on your car it shows up if the control unit answers.

Part of the Peugeot / Citroën / DS / Opel (2019+) family. The figures are for the whole family; on each car the app shows whatever its control units answer.

Shares its diagnostics with Opel / Vauxhall, Peugeot.

The security gateway

Since 2018, Stellantis group cars have a security gateway so that only the manufacturer’s tools can write to the control units. On those cars Final OBD reads everything, but it may not be allowed to clear faults or change anything. Older cars don’t have it.

Can I clear the fault codes on my Citroën?

Yes, with Pro: it reads and clears the faults in every control unit that answers, not just the engine. Clear them once the fault is fixed; if it’s still there, it comes back. On models with a security gateway they are read all the same, but the car may not let you clear them.

Can I reset the service light or do the maintenance on my Citroën?

Not yet: for this make the app doesn’t have service functions so far. It does read faults from every control unit, live data and the roadworthiness check.

Which OBD2 adapter do I need?

Any ELM327 type will do for the basics. For every control unit and the Workshop features, a good one, like a vLinker or an OBDLink. It’s all in the adapter guide.

Does it help with the roadworthiness test?

Yes, for the OBD part. It reads through the socket what the Spanish ITV test centre reads and tells you whether you’d pass under its official manual. Full details in the ITV and OBD guide.

Try it on your Citroën

Start for free with Free and demo mode. If you like it, move up to Pro or Workshop with a single payment.
