Ran obd reader myself and at mechanic and found the following; p0456 evap emission control system (very small leak) | leak detected and p190f00 coolant pump for charge pressure cooler | electrical malfunction in load circuit. Mechanic informed that the vehicle needs a software update regarding the p0456 code as no leak was found. Also that only Audi performs this update. Regarding the p190f00 code informed me that there are several recalls regarding this issue as it has been causing some severe symptoms such as engine shaking, loss of power, squealing, whining noise near or at timing belt area at start up, delayed reaction at acceleration ( takes a while to reach desired speeds), temp gauge lowering despite warm up, warming of vehicle taking longer, unable to drive over 30-40mph and rpm won't go above 2000-2500 rpms.

Aftermarket radio: pioneer electronics avh-4100 nex backup camera fails and distracts driver significantly. I have attached a scan of the complaint to pioneer electronics. The radio likely has software defect that causes very distracting failures when operating the back-up camera. Pioneer advertises that this backup camera works as advertised - it is actually now a distraction and hazard. As well, operating google "android auto" causes more significant driving distractions when using the backup camera function of the avh-4100. Complaints to pioneer electronics have been fruitless. They seem to be arrogant and claim: "all of our products are thoroughly tested. " I would like pioneer electronics to fix the software issue and create a new release that allows the backup camera to work without a distraction and safty-hazard.
