Hello, I have a v40 built in 2002 with 122 Ps and 1.8 L stroke. The car has now run 140 tkm. Since only days no longer works without any warning of the right and left turn signals. The warning flasher works and also the belt warning system turn signals, but without sound. I have already sent another relay from the recycler and a new Bosch relay. No change. Can it be on the turn signal switch silver? Or maybe also a cable break from the switch to the relay? How to test this easiest. Thank you Björn
