While diagnosing an ongoing fueling issue, I decided to replace the HP (not LP) fuel sensor. I ordered this one from Urotuning.com on the link below:


Fuel Pressure Sensor, 2.0T (0261545050)


When it arrived it looked different than the original sensor but I thought maybe it was an updated part. It didn't help my fueling issue and seemed to actually make the symptoms worse. In addition, when I ran VCDS logs, this sensor never registered anything above 90bar whereas the original registered over 120bar.


When I checked the part number they didn't precisely match and even looking at compatible part numbers it wasn't clear if this item was suitable or not.


Original item part number is: 0 261 545 008 (other markings indicate 06D 906 051A - Bosch PN Vs. Audi PN maybe...?)


The replacement item part number is: 0 261 545 050


I also found this chart on a listing on ebay that suggests these parts may not be one in the same or interchangeable?


Can anyone shed further light on this...?
