Last week I purchased a 2021 S7 with 29,5xx miles from a local BMW dealer (part of a group that includes Audi). I was told it was a four-year lease that was up. The 4-year factory warranty expired a few days prior to my purchase. The BMW dealer had an Audi tech inspect the car. Oil was changed. New OEM tires were installed. Warranty of six months/6,000 miles provided.

On a drive seven days into my ownership, first a message appeared along the lines of "steering system failure." Seconds later: "drivetrain failure." A red warning light flashed periodically that temperature was high. The car was running well and both temperature gauges indicated normal temperature.

Audi is servicing. The service advisor gave me a copy of the following exchange between the tech and Audi Corporate (I think). It's long:

"Date Updated by Status Description 11/07/24 16:16:25:US/Eastern<<<Name of tech>>>Initiated Issue Opened by Dealership 11/07/04 MIL ON, FAULT FOR P222700: Barometric Pressure Sensor "A" Circuit Range/Performance AND P04F000: EVAP system high pressure purge line performance BOTH SPORADIC. TEST PLAN FOR P222700 INCONCLUSIVE. TEST PLAN FOR EVAP OPENS AND CLOSES WITH NO ISSUES. ROAD TESTED AFTER CLEARING FAULT, NO FAULTS RETURNED. CONTACTING TAC FOR ADVICE ON FAULT P222700 Barometric Pressure Sensor "A" Circuit/Range Performance, HOW TO TEST AND PROCEED WITH IT SINCE IT MARKS THE 3RD VISIT WITH VEHICLE HAVING THIS SAME FAULT STORED, PREVIOUS VISITS TECHS CLEARED FAULT AND ADVISED CUSTOMER TO DRIVE VEHICLE. IT IS MY UNDERSTANDING BAROMETRIC PRESSURE SENSOR MAY BE IN ECM, ANY ADVICE WOULD BE APPRECIATED. THANKS! 11/07/24 17:28:00 US/Eastern<<<Name>>>Open: Consultant in Process Workshop Findings: P222700 Barometric Pressure Sensor "A" Circuit Range/Performance P04F000: EVAP system high pressure purge line performance 11/07/24: Consultant in Process Please perform the check warranty test plan under ECM guided functions then check the warranty key for TD1. Suggest to review the May 2018 Hot Topic video that describes how this purge system operates and how to test it (Access Audi > Audi Academy Video Portal > search Hot Topic https://audi-academy. kzoplatform.com/player/medium/115292111185344820333). Then perform the following tests (note that step 1 and 4 are not shown in the video): 1. Clamp off the N80 supply line between the N80 and the charcoal canister. Verify the G950 is reading correctly by starting the engine and letting it idle for one minute then record MVB "IDE 0012766 pressure tank ventilation leads, bank 1". We will compare this value to the mechanical gauge reading in step 2. Step 2: remove the G950 and install VAG1397A (minimum required tool) or VAS6213 into the port where G950 was installed. Start the engine and let it idle. What is the vacuum reading after one minute? Vacuum should be approximately 18 in/hg or -0.65bar. Step 3: shut engine off. To test the check valves, apply vacuum to the system at the G950 port using the hand pump; it should hold vacuum (note that as shown in the video, you may need to briefly cap off the line at the quick disconnect to build vacuum). Step 4: if check valve test is OK, with vacuum still applied at the G950 port remove the clamp from the N80 supply line; it should still hold vacuum. Step 5: if no issues have been identified, release the vacuum created during the previous test and reinstall the clamp on the N80 supply line. With the gauge still connected to the G950 port, route the gauge inside the vehicle so it can be seen while driving. Test drive the vehicle under load. The gauge should read approximately 12 in/hg or -0.4 bar (VAG1397A). If the gauge reads close to zero or reads positive pressure, then there is likely a problem with the Venturi in the turbo."

Obviously, since it is a new purchase and the vehicle has a history, I am worried. The tech-speak is above me, but I wonder why with multiple times the same issue was reported, more wasn't done? It looks like this tech is taking things a step (or several steps) further.

Any advice?
