Bus Parts Set for Audi A4: Heavy Load Hauling
This bus parts set is the version most often ordered for heavy load hauling on the Audi A4. It is supplied to a written specification covering material, dimensions, finish and packing, and that specification stays on file — so a repeat order is a reorder, not a new negotiation.
What usually goes wrong is ordinary: inconsistent hardness between lots, or packing that arrived crushed at the port. Both come from a specification that was never written down.

Fitment notes
Check whether the mounting points on your market version match the catalogue drawing — regional variants are the usual cause of a wrong first order.
Ordering checklist
- Confirm the model year, market version and mounting points.
- State the duty cycle; heavy load hauling is not the same specification as occasional use.
- Approve a sample built from bulk material.
- Fix packing and marking before the first container.
- Inspect before balance payment.
Questions buyers ask
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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SGS-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.
What testing is included?
Standard lots ship with dimensional and hardness reports. SGS documentation is issued with the shipment when your market requires it.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
