Audi CHRA / cartridges
A CHRA cartridge (core assembly) is the complete rotating internals of the turbo: shaft, compressor wheel, turbine wheel and bearing housing in one balanced unit. If there is shaft play or oil loss, you replace only the cartridge, while the original turbo housing and actuator stay in place. For Audi we supply cartridges for virtually all the well-known engines: the 1.9 TDI (ARL, BJB/BXE, AVF/AWX), 2.0 TDI (BKD, BMP/BMM), 1.6 TDI (CAYC) and the TFSI petrol engines from 1.4 to 2.0 litres, as well as the 3.0 TDI in the A4, A6 and Q7 and even the 2.7T from the RS4 B5. Always choose by the OEM or turbo number of your old turbo — for example 03L253016T for the GTC1244MVZ of the 1.6 TDI — so you can be certain the wheels and bearing housing fit exactly.
Why buy from us: local stock, warranty on manufacturing defects and Netherlands-based customer service.
