Product Overview

This Crankcase Vent Hose is supplied for BMW applications and is catalogued against OEM 11127588417. Matching starts from the reference rather than from a picture, which is what keeps a container of parts out of the returns pile. In service the part returns crankcase gases to the intake tract through the vent valve. When it fails it usually shows cracked elbows and oil-softened walls, and the driver sees a whistle at idle, rough running and lean mixture fault codes. We hold it as part of a cooling-system range of more than 4000 types built for the independent aftermarket in Europe, the Middle East and South America.

Key Benefits

  • Export packing as standard — The range ships to Europe, the Middle East and South America, so cartons are packed for long sea legs rather than for a local van run.
  • One reference set on every document — OEM 11127588417 appears on the quotation, the packing list and the carton label, so a warehouse can check a delivery without opening the box.
  • Mixed pallets instead of single lines — A cooling-system range of more than 4000 types means a slow-moving line can travel with fast movers instead of being ordered on its own.
  • Tooling route for obsolete references — Where the reference is out of production, we develop the mould from the sample you supply rather than turning the enquiry away.

Application Scenarios

Rebuild of an obsolete platform

The original reference is no longer produced, so the part is made from a supplied sample. With 11127588417 on the list the rest of the crankcase ventilation circuit can be priced at the same time.

Mixed container for a distributor

A quarterly container is filled across families — intake, charge air, coolant and thermostat lines — to a single packing list. This reference, 11127588417, is bought for exactly that situation on BMW vehicles.

Scheduled cooling-system overhaul

The vehicle is in for a coolant leak and the workshop replaces the whole branch at once rather than chasing the next failure in a month. This reference, 11127588417, is bought for exactly that situation on BMW vehicles.

Who It Is For

  • Workshop and fast-fit chains — replacing crankcase vent hoses on BMW daily and judging a supplier on whether the part fits first time. What they need from 11127588417 is that it fits the BMW on the ramp today.
  • Online parts sellers — listing by OEM reference, where a mismatched number turns into a return and a negative rating. They judge 11127588417 on one thing: whether it matches the part that came off.
  • Fleet and bus operators — running BMW vehicles past warranty and buying cooling-system parts by the box to keep downtime short. What they need from 11127588417 is that it fits the BMW on the ramp today.

Problems It Solves

Split ordering

Sourcing one hose from one supplier and the matching flange from another doubles the freight and the paperwork for the same repair. On 11127588417 that is settled before the quotation goes out.

Parts that are no longer produced

When the original reference is dropped, the repair still exists. Sample-based production and mould development keep the line alive. For BMW buyers it is the difference between a stocked line and a credit note on 11127588417.

Returns from wrong fitment

Every returned part costs the freight twice. Checking the elbow angles, the valve interface and the connector locks before despatch is cheaper than a credit note. With 11127588417 the check is the elbow angles, the valve interface and the connector locks, and it happens before despatch.

Technical Features

The part serves the crankcase ventilation circuit and returns crankcase gases to the intake tract through the vent valve. It is moulded in PA66 glass-filled nylon, chosen because glass-filled PA66 gives a rigid pipe that holds its shape against vibration and keeps clamp faces dimensionally stable at under-bonnet temperature.

Used where the part must hold a fixed geometry and carry bolted or clipped interfaces. PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens.

Use Guide

  1. Confirm the reference

    Match OEM 11127588417 against the number on the part you removed. Do not match on outline alone.

  2. Check the interfaces

    Compare the elbow angles, the valve interface and the connector locks before the vehicle is stripped further.

  3. Inspect on arrival

    Look for transit damage on sealing faces and connectors. PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens.

  4. Fit with the original clamp style

    Reuse the clamp type the BMW platform was designed around, and fit any seal or O-ring supplied with 11127588417 rather than carrying the old one over.

  5. Pressure check before handover

    Refill, bleed the circuit and check for oil-softened walls at working temperature before the vehicle leaves.

Answers

Crankcase Vent Hose for BMW 11127588417 — Questions Before You Order

What OEM references does this part cross to

It is catalogued against OEM 11127588417. Our internal reference is WJ-H0429, which is the number to quote on repeat orders. If your reference is not on the list, send it with the vehicle details and we will check it against the range.

Why is this part made in PA66

Because glass-filled PA66 gives a rigid pipe that holds its shape against vibration and keeps clamp faces dimensionally stable at under-bonnet temperature. PA66 mouldings crack rather than weep, so a hairline split can empty a coolant system quickly once it opens.

What is the minimum order quantity and the price

MOQ and price depend on the reference and the quantity mix, and are confirmed per enquiry rather than published. Email [email protected] with the reference and the quantity you need and you get a written quotation with packing details.

Can you supply a part that is not listed on this site

Yes. The range runs to more than 4000 types and not all of it is published. Send the OEM reference, or the old part or a drawing, and we quote from the sample — including mould development where the tooling no longer exists.

How is the part packed for export

Parts ship in cartons marked with the reference, packed for sea freight to Europe, the Middle East and South America. Carton counts and dimensions are confirmed on the quotation so you can plan the container load.

How do I check the part fits before fitting it to the vehicle

Compare the elbow angles, the valve interface and the connector locks against the part you removed. Those are the features that decide fitment on this family; a match on outline alone is not enough.

What certifications do you hold

Certification documents are not published on this site. Ask for the current documentation by email with your market in mind and we will send what applies to the reference you are buying.
