Isn't it standard practice to keep a VAG-COM and laptop in a TDI Touareg at all times?If you have an ELM 327 Blue Tooth plug in and the $5.00 Torque Pro App on your Android smart phone, go ahead, plug them in and do a Check Engine Light scan. Do NOT delete the code there. You will get a P00XX code number showing up... do a Google search for that OBD 2 code you get. If that code is a "Low Fuel Pressure" code, take a snapshot of your smart phone screen, usually by pushing the on off button and the volume up or volume down button at the same time. Save it for evidence, that screen shot.
