hi had similar problem with mine when i bought it two years ago red led never worked did,nt know it was supposed to. Everything was ok for about 8mths then started having problems with immobiliser not going off it was erratic sometimes it would other times it would,nt managed to get the car to local stealers he asked if red&green l.e.d.s were working including door l.e.d.s when i told him the red l.e.d. in the mirror was blown he said it would need replacing as that would cause immobiliser problem told him it had been perfectly ok until now(8mths) but he said that it needed to be replaced before anymore fault diagnosis could be done, and that i would have to replace the mirror complete. At this point i left then saw old school buddy whose now a mechanic there. Chatting there for a few minutes, the guy came back out and said that he could replace l.e.d. by taking it apart and soldering in a new one he said he would,nt do it normally but as i knew the mechanic he would do it as a favour, he took the mirror down, took it in to the workshop 5minutes later he was back refitted mirror and it solved the problem and he would,nt even except money for a drink. hope this answers your question.
