Strange72 0 Posted November 1, 2015 Hi. I am a new member and i have a mk4 mondeo on a 58 plate. The problem i have is with the cruise control. When it is set at speed and you want to decrease your speed it switches off. I have tried spraying electrical switch cleaner in the steering wheel as told by other people but this has not worked. It plays up every now and then. Has anybody got any idea what it could be? Have been told it could be the software in the ECU. If so i will leave it alone. Thanks.

jeebowhite 5,109 Posted November 10, 2015 Silly question, how are you reducing the speed? 1 Lenny reacted to this Share this post Link to post Share on other sites
santa 2 Posted November 14, 2015 Probably too late now... The only way to reduce speed with CC on is to use the brake or click the (-) button. Using the brake automatically switches the CC off. 2 Lenny and jeebowhite reacted to this Share this post Link to post Share on other sites
too big wheels 0 Posted February 14, 2016 Had intermittent cruise control problems on S-max - problem with steering wheel position sensor diagnosed and after expensive fix all works OK a year later. The same sensor is also part of the anti-skid system so had to be fixed for safety reasons !! Share this post Link to post Share on other sites
