I have a new (600 miles) 2015 A5 sportback. Last night I turned on valet mode for dinner and now I doesnt turns off. Ive used it 2-3 times in the past witjout problems. The only way to open the trunk is by going thru the backseats and manually move the latch mechanism. Is there anything I can di or should I taje it to the dealership and wait endlessly to them to fugere it out. Is there anything else involving valet mode? I read maybe top speed is limited. Its unnacceptable for such a new car. Thanks
