The 06K 117 021K Oil Cooler is a Genuine factory OEM replacement designed to restore precise engine oil temperature regulation on select Volkswagen and Audi TSI/TFSI applications. Specifically, this oil cooler transfers excess heat from the engine oil into the coolant circuit, preventing viscosity breakdown under sustained high-load and high-temperature conditions. Furthermore, the Genuine 06K 117 021K Oil Cooler is manufactured to exact factory dimensions, ensuring direct fitment with all coolant connections, gasket surfaces, and mounting hardware — no modifications required.
Oil cooler failures typically develop gradually, so identifying warning signs early helps prevent extensive secondary engine damage. First, milky or foamy oil visible on the dipstick or inside the oil filler cap is a strong indicator that coolant is entering the oil circuit through a compromised cooler. Additionally, unexplained coolant loss with no visible external leak often points to internal seepage within the cooler itself. Furthermore, an engine running hotter than normal under load — despite an otherwise healthy cooling system — may indicate restricted or degraded oil cooler performance. In advanced cases, contaminated oil accelerates wear across bearings and other precision internal components rapidly.

Always replace the oil cooler gasket and sealing O-rings at the time of installation — reusing old seals remains the most common cause of post-repair leaks. After installation, refill both engine oil and coolant to the correct levels using manufacturer-approved fluids. Next, run the engine to full operating temperature and inspect all connections carefully for any signs of seepage. Furthermore, monitor both fluid levels over the first several driving cycles to confirm the installation is fully sealed. Finally, if coolant contamination was present before the repair, flush the engine oil system thoroughly before refilling with fresh oil.
Always verify fitment by VIN before ordering.
