Reconditioned Audi Q3 Turbo

18 engine codes on the Q3: all turbos on this page are new

For the Audi Q3, the range covers 5 engine variants — two petrol (1.4 TFSI/TSI and 2.0 TFSI) and three diesel (2.0 TDI 184 hp quattro, 2.0 TDI 190 hp quattro, 2.0 TDI 190 hp) — paired with 18 distinct engine codes including CHPA, CHPB, CPTA, CZDA, CZEA, CUNA, DGCA, CUPA, CUWA, CYLA, DFMA, DFUA, DJGA, DDAA, DFCA, DFHA, DNVB and DNNA. All turbos listed here are new parts, sold as a straightforward purchase.

Petrol and diesel: two very different reference logics

On the petrol side, the 1.4 TFSI/TSI has the greatest number of manufacturer references: over twenty references in 04E145… coexist depending on the exact engine code — notably CZDA, CZEA, CUNA and DGCA. The 2.0 TFSI (codes CHPA, CHPB, CPTA) has a narrower range of references. On the diesel side, the three variants of the 2.0 TDI share the 04L253… family but do not use the same references depending on power output and engine code: a 2.0 TDI 184 hp (CUWA, CYLA) and a 2.0 TDI 190 hp (DFMA, DFUA, DJGA, DDAA, DFCA, DFHA) differ in their CHRA and variable geometry, even at the same engine capacity.The engine code stamped on the block is the only reliable criterion for selecting the correct reference.

Why diagnose before replacing your turbo?

Before any replacement, it is essential to diagnose the root cause of the failure: oil circuit contamination, blown turbo seals, a foreign body upstream of the compressor, or damage linked to the diesel particulate filter are the most common causes on the Q3's 2.0 TDI engines. Fitting a new turbo without addressing the source of the problem risks premature failure.
