Power Steering Light On problems of the 2014 Audi A4

While in a turning motion thru a water puddle, the steering defective warning light came up on the dash and the steering was very stiff at slow speed. Error was analyzed as a defective electric steering rack and pinion. One year ago this same problem arose and it was corrected with a used rack, because a new one could not be found, such is the case at the current time, only used racks are available, which did not work out well the first time and the lead time on a new rack is 3 months. I submitted a complaint number: 11300855 on the same exact problem a year ago. I feel Audi needs to address this serious problem with the rack p/n 8k1 423 055ba or any other that fit this description. The internet has plenty of Audi forums about this moisture problem, since the rack is conducive to weather related conditions that short out control module, leaving the rack with no electric power assist. The module is integrated into the rack with no way to just replace just that part, leaving you with a $3000. 00 bill.
