Hello, vehicle: Lupo 6X 1.4 16V, MKB AUA Model year 2001 Problem: The radio locking of the original (not retrofitted) ZV does not work. At no push of a button something happens, keys cannot be learned. All other functions of the comfort control unit work. Previously tested: -Measurement blocks in the comfort control unit—> voltages, door contact switches etc., FFB keys show as expected no reaction batteries in the original radio container exchanged (LED lights up at Keystroke) -new 433MHz wireless container tested—> could also not be learned -comfort control unit exchanged for a part number-like model from a Golf 4—> no change -plug/wire harness tested on the control unit—> nothing striking, looks io The AutoScan from VCDS with the “new” comfort control unit is attached. Unfortunately, it works as usual, except for the radio operation. When learning the keys I first reset the learning values of the Stg and then versuc After that the error entry 01179- key programming is wrong Now my guess is that I had an uncompatible new radio container for testing. I only paid attention to the design and frequency. Is there any more to consider or can someone tell me which radio container I need for my model? Thank you for your help.
