June 11, 20196 yr I’m getting a overboost and then engine lights comes on when plugged in it says this see pic Sent from my iPhone using Tapatalk
June 11, 20196 yr Has it been mapped ? Has it got any modifications? If not then check vacuum lines from boost solenoid, actuator and inlet manifold for leaks ,cracks or missing hoses . If Nothing seems visually wrong you can remove the boost solenoid and clean it with brake cleaner to see if that improves things . Failing actuator could be another culprit but you'd need to pressure check that with a vacuum pump to see if its operating at the correct pressure for your model .
June 11, 20196 yr Author Yes has been modified boost is normally 1 1.2 bar max it’s going up to 1.4 - 1.5 then it like it hits a wall and engine light comes on . I have cleaned solenoid no difference Sent from my iPhone using Tapatalk
June 11, 20196 yr If it's had "breathing " mods like decat ,intake pipework, cone filter ect it should be mapped . I assume it hasn't been mapped as most mappers would have mapped in a higher 1.4/ 1.5 boost target. If it hasn't been mapped that might well explain why you're getting overboost , as the oe ECU parameters can be exceeded because boost control system will be working overtime trying to keep the boost in check . This could cause the boost solenoid or actuator to weaken . Personally I wouldn't drive a unmapped scooby with breathing mods on boost until its been mapped. There's only really boost solenoid, actuator, ECU solenoid duty and vacuum lines that control boost , so one of those is at fault .
