paulfern 0 Report post Posted September 23, 2012 Hi, im currently having trouble with my Alfa Romeo 156 2ltr selespeed. It keeps putting itself into neutral and stalling whilst slowing down.Also have an engine light on that relates to the selespeed along with beeping every 90 seconds. Just had a diagnostics test and error code P1653 displayed. Cant find any traces of this code in my alfa manual. Any feedback would be appreciated. Thanks.
