Audi A3 8V ('13) Front LED indicators (turn signal)

I have these now for two years and all good but when I turn them on DAB radio will immediately stop working like it gets shock and then after few seconds it will start playing again..?
 
Had this is a VW Golf MK7 customer. He had halogen rear clusters and had purchased some Aliexpress LED “plug and play” replacements he wanted me to fit. Every time he put his foot on the brake during the day his radio would cut out, and could not use the radio when night or overcast, or when his side lights automatically came on
