Hi Guys, Have got the same problems with mine ,From the research I have done most likely its the vacuum lines leaking or the actual cruse control ecu as it is prone to the solder "de laminating" I think thats what it is called ,The ecu can be fixed by sticking it in the oven to re-flow the solder joints ,a tactic used by gaming machine owners ,I think details are on rennlist of the exact temperature and time required ,I am lucky that I have a spare ecu which I will swap out to see if it works before Baking one of them!! Good luck Jez |

Hi Potdog The S4 cruise all electric/electronic, so no worries about vacuum! I agree with suggestion that solder joints in cruise ECU (located centre console, behind radio) is a likely suspect. People have had good success opening up and reflowing the joints. Cheers Adrian |
