Turbo Cooler Hose Pipe for Audi OEM 1K0145790C

Product Overview

A Turbo and Intercooler Hose for Audi vehicles, held against OEM 1K0145790C. In service the part carries pressurised charge air between the turbocharger, the intercooler and the inlet manifold. This part carries pressurised charge air between the turbocharger, the intercooler and the inlet manifold. The failure modes that bring it across a parts counter are delamination where charge air temperature peaks and heat-hardened elbows, reported as boost loss under load, limp mode and a measurable drop in charge pressure. 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

• Consolidate the platform in one order — Hoses, flanges and thermostat housings for the same platform ship on one pallet, which shortens the paperwork and the freight bill.
• Sample-based production for parts not yet listed — Send the old part or a drawing and we quote from the sample, including mould development where no tool exists.
• Inspection before despatch — Parts are inspected before they leave, which for this family means checking the sealing faces and the connector geometry that decide whether it fits.
• Matched to how the part actually fails — Delamination where charge air temperature peaks and heat-hardened elbows are the reasons this reference is bought, so those are the features checked before packing.

Application Scenarios

Warranty-expired fleet maintenance

A fleet past dealer coverage moves to independent supply and needs the same reference coverage at a working price. For 1K0145790C the practical step is confirming the cuff diameters, the bend angle and the clamp or quick-connect style at each end before the order is placed.

Counter stock for a busy platform

Audi volume in the region justifies holding the line on the shelf instead of ordering it in per job. This reference, 1K0145790C, is bought for exactly that situation on Audi vehicles.

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. This reference, 1K0145790C, is bought for exactly that situation on Audi vehicles.

Who It Is For

• Online parts sellers — listing by OEM reference, where a mismatched number turns into a return and a negative rating. For them 1K0145790C is a line on a shelf, not a project.
• Fleet and bus operators — running Audi vehicles past warranty and buying cooling-system parts by the box to keep downtime short. For them 1K0145790C is a line on a shelf, not a project.
• Radiator and cooling specialists — rebuilding cooling systems and sourcing the hoses, flanges and housings for a platform in one go. They order 1K0145790C by the carton and reorder against the same number.

Problems It Solves

Unclear compound

EPDM hardens once it has been heat-cycled past its service window, so a replacement that has sat in a hot warehouse for years is not a bargain. That is why 1K0145790C carries its full cross-reference set on this page.

Reference mismatch

Visually identical parts carry different connector geometry between model years. Quoting OEM 1K0145790C fixes the identity before money moves. On 1K0145790C that is settled before the quotation goes out.

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 1K0145790C.

Technical Features

The part serves the charge air circuit and carries pressurised charge air between the turbocharger, the intercooler and the inlet manifold. It is moulded in EPDM rubber, chosen because EPDM keeps its elasticity through repeated heat cycles and resists ozone, water and weathering, which makes it the workhorse wall compound for moulded engine-bay lines.

Specified where the part has to stay flexible over thousands of heat cycles rather than hold a fixed shape. EPDM hardens once it has been heat-cycled past its service window, so a replacement that has sat in a hot warehouse for years is not a bargain.

Comparison With the Alternatives

Use Guide

1. Confirm the reference

   Match OEM 1K0145790C against the number on the part you removed. Do not match on outline alone.

2. Check the interfaces

   Compare the cuff diameters, the bend angle and the clamp or quick-connect style at each end before the vehicle is stripped further.

3. Inspect on arrival

   Look for transit damage on sealing faces and connectors. EPDM hardens once it has been heat-cycled past its service window, so a replacement that has sat in a hot warehouse for years is not a bargain.

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 1K0145790C rather than carrying the old one over.

5. Pressure check before handover

   Refill, bleed the circuit and check for blown cuffs at clamp joints at working temperature before the vehicle leaves.
