Coolant Thermostat Housing Assembly for VW & Audi 06A121114

Product Overview

Ordered against OEM 06A121114, this Thermostat Housing Assembly replaces the original part in the coolant control circuit on Audi vehicles. The carries the wax element, housing, seals and — on mapped units — the heater and temperature sensor that govern warm-up, so form and fit are not negotiable. Because the part carries the wax element, housing, seals and — on mapped units — the heater and temperature sensor that govern warm-up, a worn one rarely fails cleanly — expect seals that take a set after repeated heat cycles and cracked plastic housings long before it separates, with a gauge that never settles in the normal band, higher fuel consumption and thermostat fault codes as the first complaint over the counter. Hunan Woojin Autoparts supplies it from a cooling-system range of more than 4000 types covering German, French, Japanese, American and Korean vehicles.

Key Benefits

• Checked on the features that matter — Inspection concentrates on the opening temperature, the housing outline and whether the unit is map-controlled — the dimensions that put a part back in the box if they are wrong.
• Built for the duty of the coolant control circuit — The part carries the wax element, housing, seals and — on mapped units — the heater and temperature sensor that govern warm-up, so the compound and the wall construction are matched to that circuit rather than to a generic hose spec.
• 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 06A121114 appears on the quotation, the packing list and the carton label, so a warehouse can check a delivery without opening the box.

Application Scenarios

Breakdown repair

The vehicle is off the road and the part has to be right the first time, which makes the reference match the whole decision. Here the thermostat housing assembly is ordered against 06A121114 and travels with the rest of the Audi branch.

Rebuild of an obsolete platform

The original reference is no longer produced, so the part is made from a supplied sample. This reference, 06A121114, is bought for exactly that situation on Audi vehicles.

Mixed container for a distributor

A quarterly container is filled across families — intake, charge air, coolant and thermostat lines — to a single packing list. Here the thermostat housing assembly is ordered against 06A121114 and travels with the rest of the Audi branch.

Who It Is For

• Workshop and fast-fit chains — replacing thermostat housing assemblys on Audi daily and judging a supplier on whether the part fits first time. For them 06A121114 is a line on a shelf, not a project.
• Online parts sellers — listing by OEM reference, where a mismatched number turns into a return and a negative rating. 06A121114 earns its shelf space through repeat demand on Audi platforms.
• Fleet and bus operators — running Audi vehicles past warranty and buying cooling-system parts by the box to keep downtime short. What they need from 06A121114 is that it fits the Audi on the ramp today.

Problems It Solves

Unclear compound

Confirm the compound against the reference before ordering, because visually identical parts are moulded in different materials. For Audi buyers it is the difference between a stocked line and a credit note on 06A121114.

Reference mismatch

Visually identical parts carry different connector geometry between model years. Quoting OEM 06A121114 fixes the identity before money moves. For Audi buyers it is the difference between a stocked line and a credit note on 06A121114.

Split ordering

Sourcing one hose from one supplier and the matching flange from another doubles the freight and the paperwork for the same repair. For Audi buyers it is the difference between a stocked line and a credit note on 06A121114.

Technical Features

The part serves the coolant control circuit and carries the wax element, housing, seals and — on mapped units — the heater and temperature sensor that govern warm-up. Material for this reference is confirmed per enquiry. The listed opening temperature is 105°C, which is the figure that has to match the vehicle.

Matched to the circuit the part serves. Confirm the compound against the reference before ordering, because visually identical parts are moulded in different materials.

Values marked TBC are not stated on the source catalogue. They are confirmed in writing on the quotation rather than estimated here.

Comparison With the Alternatives

Use Guide

1. Confirm the reference

   Match OEM 06A121114 against the number on the part you removed. Do not match on outline alone.

2. Check the interfaces

   Compare the opening temperature, the housing outline and whether the unit is map-controlled before the vehicle is stripped further.

3. Inspect on arrival

   Look for transit damage on sealing faces and connectors. Confirm the compound against the reference before ordering, because visually identical parts are moulded in different materials.

4. Fit with the original clamp style

   Reuse the clamp type the Audi platform was designed around, and fit any seal or O-ring supplied with 06A121114 rather than carrying the old one over.

5. Pressure check before handover

   Refill, bleed the circuit and check for cracked plastic housings at working temperature before the vehicle leaves.
