OE Cross Reference
Frequently Asked Questions
What is the difference between 03L and 04L EGR cooler numbers?
03L prefix numbers (03L131512CF, 03L131512DN) are for the EA189 engine family (2008-2015). 04L prefix numbers (04L131512BP, 04L131512AA) are for the newer EA288 engine family (2012+). The two are NOT interchangeable — always verify your engine code before ordering.
Which VW/Audi TDI engines have EGR cooler problems?
The most commonly affected engines are: EA288 2.0 TDI (DFGA, DFHA, DETA codes) and EA189 2.0 TDI (CJAA, CBEA codes). The EGR cooler typically needs replacement between 80,000-150,000 miles depending on driving conditions and maintenance.
How do I identify my VW TDI engine code?
The engine code is stamped on the engine block (usually front-left on EA288). You can also find it in the vehicle documentation or by scanning the VIN. Common codes: DFGA/DFHA (Golf/Passat 2.0 TDI 150hp), DETA/DGCA (A4/A5 2.0 TDI 190hp), CJAA/CBEA (older EA189 2.0 TDI).
