    Thank you and any imput will greatly be appreciated. The code is PO492. System not ready for testing after trying to go through again. My car is E65 I think.

    po492 fault code is secondary air injection (AIR) system bank 2-malfunction probable cause is... wiring AIR selonoid, hose connections, mechanical fault. i think ( but dont hold me to this lol ) once you have repaired the fault it has to go back on machine to erase fault code once fixed, and that could be why you have that fault again. hope this helps and if you need any more info dont hesitate to ask, good luck, troy

What is a IHKA module and a IDrive screen on a 7 series 745li bmw 2004 and how to fix it

The iHKA is the air conditioning control unit. The panel where you turn on and off the air conditioning and adjust the temperature. The I-drive screen is actually called a CID and it is a control display for all the functions such as navigation, radio, settings, climate control, services due, etc... There really is not a way to fix them without replacement. The control units are programmed to the vehicle and are usually VIN specific and cannot be used from car to car without causing other issues. I have used them temporarily to test a module but never left in or tried coding mine to another model. That makes it hard because you must replace it and that is expensive !!! You can try a used one from a junk yard but most likely will cause new issues

Solution to p1351

P1351 just means there is a misfire. Was there a note next to the code stating which cylinder(s)? I would start by replacing the spark plugs, there could just be a fouled plug. If that doesn't help, pull the ignition coils and boots and see if there is oil in any of the spark plug tubes/boots. If there is, you need to replace the valve cover gasket.

1998 328i.. Got a 1421 and 1423 code...not sure where to start...

1997 BMW 328I 2.8L Customer Concern: MIL is on with trouble codes P1421 and P1423, for incorrect secondary airflow on both cylinder banks. Tests/Procedures: 1. Perform a functional test of the Air Injection Reaction (AIR) system. Tee a vacuum gauge into the vacuum hose attached to the diverter valve, located on the cylinder head towards the front of the engine.

2. Allow the vehicle to sit over night. Start the engine (cold) while monitoring the amount of vacuum on the gauge at startup. At temperatures from -10 to 40 degrees Celsius, there should be at least 17 inches of vacuum. At the same time, the AIR pump should run and pump a large volume of air into the exhaust. Potential Causes: A.I.R. Pump
Air Pump Relay
Restricted Cylinder Head
Diverter Valve
Tech Tips: These codes are related to a problem detected in the Secondary Air Injection system. Scan tools with BMW software include a feature to command the AIR pump on and off. The pattern failures for these codes are the AIR pumps due to leaks in the diverter valve and moisture or condensation in the AIR pump.

Possible fix but not all items. Just areas to look at:
Confirmed Fix - A.I.R. Pump - A.I.R. Diverter - A.I.R. Pump, Air Injection Reaction Diverter (AIRD) Valve - Air Injection Reaction Diverter (AIRD) Valve - Check Valve, Secondary Air Pump - Diverter Valve Vacuum Lines
