does anyone know what these codes are and what the cause(s) might be?
From the Ross Tech wiki:-
16514/P0130/000304 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit [h=4]Possible Causes[/h]
Oxygen (Lambda) Sensor Heating Bank 1 Sensor 1 faulty
Check Oxygen (Lambda) Sensor Heating Bank 1 Sensor 1
17924/P1516/005398 - Intake Manifold Valve (N156): Open Circuit [h=4]Possible Causes[/h]
Wiring from/to Intake Manifold Valve (N156) faulty
Intake Manifold Valve (N156) faulty
Check/Replace Intake Manifold Valve (N156)
Perform Output Test.
Use Scope to check Activation Signal while performing an Output Test.
18001/P1593/005523 - Altitude Adaptation: Signal Out of Tolerance [h=4]Possible Symptoms[/h]
[h=4]Commentary[/h]This is one of those fault codes where the ECU knows something is amiss, but cannot pinpoint the cause.
MAF sensor (G70) out of tolerance.
Leak in intake system.
Throttle position sensors (G187/G188) out of tolerance.
Check MAF/replace MAF Sensor (G70).
Check intake systems for leaks and repair.
Check Throttle position sensors (G187/G188).
18010/P1602/005634 - Power Supply B+ Terminal 30: Voltage too Low [h=4]Possible Causes[/h]
Cables on the Battery were removed
Battery weak (voltage)
Check Battery Cables
If multiple Control Module have Power Supply Faults stored, it's most likely to be one common Problem like the ones shown above. Otherwise when only one or two Control Modules have such Codes stored you better start searching at the individual Power Supply of these Modules.
Terminal 30 means unswitched battery power that is supplied even when the ignition is off. This is not referring to any physical terminal numbered 30.
Clear all codes, then check back after a couple of days to see what is active before diving into 'fixing' stuff
ok thanks v much everyone
