So the rns 510 in my 2014 passat tdi sel works when it wants to. Sometimes not coming for weeks. two days ago i found a guy selling a rns 510 out of his 2010 jetta sports wagon. i got the pin and installed it two days ago. The main problem i was getting is that it did not have sound. So i looked up what was needed to re-code using vcds. So I re-coded it using some of the info i found online mainly vwvortex and eurozonetuneing and completed a hard reset. Once i reset the head unit my car started acting funny. First it was a airbag error then a brake error, this turned into my car not able to start or turn off. The instrument panel is now flashing constantly on and off. Any tips etc will be appreciated.
