Tire Pressure Sensor for BMW 3 Series: Magnesium Alloy
This tire pressure sensor for the BMW 3 Series is specified around magnesium alloy, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is a fitment that looked right on paper and failed on the bench, or lead time that slipped twice before bulk started. Both are specification problems, and both are preventable.

Fitment notes
Confirm the fitment against the VIN or the frame number before ordering; two model years often share a name and not a part.
Where it is used
The specification above is the one most often ordered for rural transport. Related applications include coastal delivery, construction sites, roadside assistance, weekend riding, delivery fleets.
Quality and packing
- In-line inspection with AQL 1.5 sampling on every lot.
- Dimensional report issued against the approved drawing.
- Carton marking and barcode to your specification.
- Golden sample retained at the factory as the reorder reference.
Questions buyers ask
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the RoHS-compliant build instead of a fresh interpretation.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
