Seat fault codes
12 distinct codes across 13 real diagnostics on Seat, including the Seat-specific ones no generic code list can decode.
Seat-specific codes
These are manufacturer-specific, which means the same code on another marque is a different fault. That is exactly why they have no page of their own here and no entry in any generic code list: a single description for one of these would be wrong more often than right. Below they are scoped to Seat, ranked by how often we have actually seen them, which is a claim we can stand behind.
| Code | Diagnostics on Seat |
|---|---|
| P1B01 | 2 |
| B1899 | 1 |
| C1112 | 1 |
| P334B | 1 |
| P334C | 1 |
| U1123 | 1 |
To turn one of these into a cause you need the marque, the model and the engine, which is what the tool does. A code on its own is a starting point, not an answer.
Standard codes we see most on Seat

Frequently asked questions
How do I run a diagnosis?
Select the vehicle on Start, click the Diagnostic card and choose New diagnostic. Fill in the description, the error codes and the mileage, then click Analyze.

Do I have to type the codes from my scan tool?
No. Click the camera button next to Error codes and take or choose a photo (JPEG or PNG) of the scan tool's screen; WrenchLane reads the codes and their descriptions into the form. You can also speak them with the microphone.

Are the public fault code pages built from my diagnostics?
They are built from anonymised, aggregated diagnostics run in WrenchLane; no workshop, customer or vehicle can be identified. Each fault code page shows how often the code was seen across those diagnostics and in how many separate workshops.
