OE 17137601949 — Expansion Tank for Bmw

The Related OE References table above lists the alternates we see most often in trade inquiries. Cross-references work because the engineering envelope is shared across the engine & fuel system family — always confirm dimensions and connector layout before you swap.

Every shipment of 17137601949 leaves with a packing list, photo documentation and a QC report. Warranty terms are agreed per contract and reference that inspection record; claims are settled in writing against the documentation.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded expansion tank transfers stress to neighbouring components, so a small repair can grow into a full engine & fuel system rebuild. Book the replacement once the symptom is repeatable.

Three checks: the code printed on your old part must read 17137601949; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest engine & fuel system reference and narrow by build year. Send photos and we will cross-check the number for you.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.
