From 2009 to 2015, Volkswagen produced the 1.4-liter CDGA 1.4 TSI EcoFuel turbocharged engine, which was fitted to methane versions of well-known vehicles like the Passat and Touran. This device is built to run on compressed natural gas, or CNG.
CBZA, CBZB, BMY, BWK, CAVA, CAVD, CAXA, CDGA, and CTHA are all part of the EA111-TSI series.

Disadvantages of the VW CDGA engine
This engine is terrified of low-quality fuel because it is built to run on gas.
Detonation frequently destroys pistons, and many just replace them with forged ones.
Compression drops and soot cover intake valves, even when fuel is of poor quality.
Replacing an unreliable timing chain accounts for a sizable portion of service station calls.
Both the wastegate and the electronic control valve in the turbine fail most frequently.
People frequently complain about antifreeze leaks and engine vibrations in cold weather on specialized forums.
