Idle problems and fault codes. Help please
The car has been faultless for quite a while. Been really enjoying it. I've noticed the mpg has gone down quite a bit. Strange I thought. Then last week out of the blue the EML light came on. Straight away it went into limp home mode. Zero power.
The car is idling at between 1100 to 1600 rpm So i plugged it in and had these faults 128 devation idle speed 223 pressure intake manifold 136 idle speed regular 144 & 145 lambda sensors. I've replaced the idle control valve but the codes 128 and 223 are still present. Dodgy map sensor ??? BMW want £335 for the sensor 😂😂 Any ideas please |
Quick update of my problems and the fix.
One of the throttle body stop screw head's had snapped. Over time the thread had screwed itself in more holding the butterfly open when it should have been shut on idle. Thus causing a air leak😀😀😀😅 Only found when we put pressurised smoke through the idle valve rail. The fix was to remove the damaged thread and renew the bolt and nut. Set it all up and no air leak. Car is now back to its amazing self 😆 |
thx for the update. Many don't follow up. :thumbs:
