How do I know which one applies to my car?

Which one is yours

A generic OBD reader gives you the number, not which of these meanings your manufacturer assigned to it. To get to the specific one:

  1. Use a brand-specific scanner — VCDS for VAG, INPA or ISTA for BMW, XENTRY for Mercedes, Forscan for Ford. It shows the manufacturer's own text rather than the generic one.
  2. Read all stored codes together — the neighbouring ones usually point at which system is involved and narrow the list.
  3. Check freeze-frame data: the RPM, temperature and load at the moment it triggered indicate which system was active.
  4. If you have no brand scanner, tell me the make and model below and I will tell you which of these applies to your car.
What kind of code is B1xxx?

B1xxx is body systems, manufacturer-specific.

How serious is it?

Severity

Manufacturer-specific body system — needs a brand scanner to read the actual cause.

And on my car specifically?

That is what holds for B1280 in general. From here it depends on your engine — tell me which car it is and what it does, and I will give you the steps for it: real procedures, torque figures and diagrams instead of general advice.

Who makes these pages, and how

TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.

The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.

The same code can mean different things on different makes. Match the meaning to your make before acting on it.
