On the 2013-2024 Audi A4 allroad 2.0T, the EA888 2.0T engine uses an electric water pump that is prone to premature failure, typically between 60,000 and 100,000 miles. The internal impeller can crack or the electric motor can fail, causing loss of coolant circulation and potential overheating. This is the same issue affecting A4, A5, and Q5 models with the EA888.

This issue also affects: Hyundai Santa Fe, Volkswagen Eurovan, Audi A4

Common Symptoms

Coolant temperature warning light
Engine overheating
Coolant leak from water pump area
Low coolant level without visible external leak
Heater blowing cold air intermittently

How to Fix

Replace the water pump and thermostat together. Use the latest revision OEM water pump which has a reinforced impeller. Flush the cooling system during replacement to remove any debris from the failed pump. Monitor coolant temperature closely if symptoms appear.

Parts and tips from 1,100+ owners who fixed this issue

UpgradeUse the latest revision Genuine VW/Audi water pump 06L121111H which supersedes earlier failure-prone versions. Do NOT use aftermarket pumps — Graf and URO units have documented early failures on Audizine. (Genuine VW/Audi #06L121111H)

TipAlways replace the thermostat and thermostat housing at the same time. The plastic housing becomes brittle with heat cycling and will crack shortly after pump replacement.
NoteIf you see coolant temperature spike, pull over and shut off the engine immediately. The EA888 aluminum head warps quickly when overheated, turning a $1,200 water pump job into a $5,000+ head gasket repair.

Typical repair cost:$800 - $1,800

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: Hyundai Santa Fe, Audi A4, Audi A5

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.

What Owners Are Using

Parts and tips from 450+ owners who fixed this issue

UpgradeUse Genuine VW/Audi output shaft seals. Aftermarket seals from Corteco or National often leak within a year per Audizine reports. (Genuine VW/Audi #0CQ525275B)
View on Amazon
TipUse Motul Gear 300 75W-90 or Liqui Moly 75W-90 GL-5 for the differential fluid. These synthetic fluids provide better seal conditioning than conventional gear oil.
TipCheck the differential breather vent tube while you are under there. A plugged vent causes pressure buildup that accelerates seal failure.

Typical repair cost:$400 - $900
