Hi first time posting. I searched the forums and could not find anything online about location of sensor 3. My friend had a 2017 BMW 328D xdrive left to her. It needs the EGT sensor bank 1 sensor 3 replaced. Is it located under right side floor board? Looks like there are 2 on the Diesel Particulate Filter and wanted to make sure there was not another one hiding up in there. The dealer is 90 mins away and gave her a price of just under $1000.00 to replace a $100.00 sensor. Thanks for any advice.
