Current Audi TSB 2070349/4 applies only to 2021-2024 RS5 Coupe and RS5 Sportback V6 vehicles when the customer reports coolant loss/leak, a coolant warning or an engine warning and the workshop identifies the coolant pump as the leak source. Audi states that up to 3 ml of coolant on the pump drip cup over 100 operating hours can be normal seal lubrication/cooling. Dried coolant deposits on the vacuum connection alone are not clear evidence of a leak. Coolant contamination at change-over valve N649 may produce P0299 as a secondary condition. The bulletin does not support a universal turbocharger coolant-feed-line cracking defect or the frozen line part numbers.

This issue also affects: Audi A1, Audi A3, Audi A6

Common Symptoms

  • Coolant loss or visible leak
  • Coolant warning lamp
  • Engine warning lamp

How to Fix

Locate the leak before replacing parts. Clean and dry the area, fill the cooling system to maximum, inspect at idle and at engine speeds up to about 2,500 rpm, and perform the Workshop Manual cooling-system leak test. If no further leak is detected, continue observation without replacing parts. If a leak recurs, replace only the component or components causing the leak and document the finding with clear photos or video; a pump-leak repair also requires a photo of the pump production date. Inspect the vacuum circuit and N649 when contamination or P0299 is present, following current Audi workshop and parts information.
