On the 2013-2016 Audi A4 allroad 2.0L TFSI EA888 Evo2, nHTSA 18V229 covers affected 2013-2016 A4 allroad vehicles with the 2.0L TFSI EA888 Evo2 engine whose electric after-run coolant pump can become blocked by cooling-system debris and overheat, or short-circuit from internal moisture, creating a fire risk. The production population ran from March 12, 2012 through April 1, 2016 with nonsequential VIN endpoints WA1UFAFL8DA028484 and WA1UFAFL8GA018283; eligibility must be checked by VIN. This is not the main mechanical coolant pump or thermostat assembly.

Common Symptoms

  • EPC warning related to a blocked electric after-run coolant pump

How to Fix

Check the VIN and current open-action status with an Audi dealer. When Service Action 19N8 is open, Audi directs installation of the revised electric after-run coolant pump and an ECM software update. An EPC warning can indicate a blocked pump on vehicles with the relevant software; contact a dealer without delay. Do not buy a main pump, thermostat module, impeller kit or generic replacement from this campaign card, and do not infer eligibility from model year alone.

On the 2013-2024 Audi A4 allroad 2.0T, the quattro all-wheel drive rear differential can develop oil leaks at the output shaft seals. The seals dry out and crack over time, particularly in hot or arid climates. Low differential fluid can lead to bearing and gear damage if not caught early. Typically appears after 50,000-70,000 miles.

This issue also affects: Audi A5, Audi Q3, Audi Q5

Common Symptoms

  • Oil drip spots under rear of vehicle
  • Whining noise from rear differential under load
  • Fluid residue on rear differential housing
  • Burning oil smell from rear of car
  • Low differential fluid level at service

How to Fix

Replace the rear differential output shaft seals. Service the differential fluid (75W-90 GL-5) at the same time. Inspect the differential vent tube for blockage, as a clogged vent builds internal pressure that pushes seals out.

Typical repair cost:$400 - $900
