Hello, I have a question about the speed sensor / lock switch on my 850er. It has already happened 3 times now that the yellow arrow flashes with the indicator lights. It then switches into the emergency program and you can hardly make any progress. After 5 – 10min the thing has been done and it switches as usual. The lamp then goes off at some point. Error code read out : 3-1-3 – signal from the speed sensor out of range. Even clean or replace falls flat with me. However, I have a cheap screwdriver. At SKANDIX I have found something suitable :http://www.skandix.de/…/ But unfortunately no longer available. You only offer the original from VOLVO for 170€. The other one has probably cost 83€. To me the original one is too expensive. has much. someone to buy or knows a shop at which I can order a cheap one. Still a general question: How urgently do I have to do this? I drive the car still at the woend. and then only about 150km max.
