From 2004 to 2008, the company assembled the 2.0-liter Audi BRE 2.0 TDI diesel engine, which was fitted to well-known models like the A4 in the rear of the B7 and the A6 in the rear of the C6. Contrary to popular belief, this motor’s injectors were electromagnetic rather than piezo.
The EA188-2.0 series also includes: BKD, BKP, BMM, BMP, BMR, BPW, BRE, BRT.

Disadvantages of the Audi BRE engine
The most well-known issue with this diesel engine is the oil pump’s hexagon’s quick wear.
Although they are a good resource, electromagnetic unit injectors are very costly to replace.
Additionally, a lot of owners lament the 0.5 liters of oil used per thousand kilometers.
Engine thrust failures are typically caused by EGR contamination or the turbine geometry wedge.
A clogged particulate filter is frequently another cause of the motor’s erratic operation.
