Do B6 TDI's have O2 sensors

[m8gic]

Hi I was just curious as I had the impression diesels do not have oyygen sensors. Someone told me that that some diesels do have o2 sensors I was wondering if the Audi A4 TDI 2001-2005 models have oxygen sensors.

From looking at my -02 TDI I'd say they don't. The MAF and MAP sensors are the 2 sensors that pretty much collect all the data needed for the ECU.

The cars that have DPFs might come with O2 sensors?
