Reconditioned Volkswagen Passat Engine

Which Volkswagen Passat engine for the 2005–2015 generations?

Between 2005 and 2015, the Passat spanned two generations (B6 then B7) and received significantly different engines depending on the year of production. A naturally aspirated 1.6 sits alongside turbocharged TSI petrol units and several TDI diesel families: engine capacity alone is not enough to identify the correct engine. It is the engine code — four letters stamped on the block — that determines the exact reference to order.

Diesel: two TDI families, seven distinct codes

The 1.9 TDI is the most common, with five codes: AVQ, BRU, BSU, BSW and BXJ. These codes cover different power outputs and model years; they are not interchangeable. The 2.0 TDI of the same period comes in two codes — BMP and BMR — corresponding to distinct mechanical architectures despite an identical engine capacity. A 2.0 TDI with code BMP and one with code BMR do not share the same internal specifications.

Petrol: from the naturally aspirated 1.6 to the TSI units — no shared components

The 1.6 (codes BGU, BSE, BSF) is a naturally aspirated block with no turbo, fitted to the entry-level versions of the B6. It shares no parts whatsoever with the TSI units. The 1.8 TSI (code CDAA) and the 2.0 TSI (codes CCZA, CHHA, CHHB) belong to turbocharged direct-injection generations; the CHHA and CHHB codes of the 2.0 TSI themselves denote two different internal variants. The 1.4 TSI code CZDA arrived towards the end of this period on the B7, featuring more aggressive downsizing. Checking the engine code before placing any order is essential whenever a single engine capacity encompasses several codes.
