02 745i - Trouble codes

Hello everyone!!! Long time reader first time poster!!!

I have an 02 745i with 40,000 miles. Recently she threw codes p1043 and p1062.

Here are the symptoms. I had a reduced power warning a couple of days ago. I turned off the car and started her up with no problems. Yesterday the same thing happened and again I restarted her and it went away. Except this time it was followed by the check engine light.

After reading the OBD II codes I get the above mentioned codes. A thorough search of bimmerfest lead me to many websites that had codes listed by my specific codes do to show.

Can someone help me to diagnose these codes???


Thanks!

Tom

Found this for code P1043 :

Fault code for variable valve timing...........will require diagnosis with BMW compatible scan tools.

Variable valve timing faults as described for this vehicle actually relate to the variable valve lift control. Instead of having a traditional valve body, this vehicle uses a system to control the valve lift and therefore intake air volume.

Aside from performing diagnostics with a BMW compatible scan tool, check power and ground at the valvetronic control unit.



Found this for code P1043 :

P1062 is variable valve timing bank 1 limp home mode, full stroke position not reached. remedy is check wiring at vanos, check connections or engine control module
fault.



Found this for code P0363 :

Code P0363, means a mutliple cylinder misfire has occured. The computer was unable to determine which cylinder it is or all cylinders are missfiring at random and no specific order.

Remember that codes can create other codes.

The first thing you should followup on is the Misfire. That is the mostly cause of all the errors and easiest to troubleshoot.

Take out the plastic covers. The top one via 4 size10 nuts the one that says BMW by simply pulling out. You will see an electric motor of which the tip is shoved into the head cover (bank1 which is cylinders 1-4 (right side)). Check for any abnormal signs, say for discolourations, etc. This motor turns as the result of which the eccentric shaft will move up or down causig your valve lifters to fully or partially open the valves. It could well be your servomotor. These fail on 4 cylinders everytime it's Tuesday and remember BMW V8s are really (believe me they are) 2 of those 4s. They are just so alike. But I'm only guessing. Check also for signs of oil sludge or dirt/debri inside the engine as this can form into unclear signals from the eccentric shaft sensor which sits at the very end of the inlet shaft where it is toothed to help this sensor generate signals telling the Valvetronic unit how things are and it telling the servomotor to bolt on or off. I hope I'm making sense.

Usually people will test it with water and try to "rotor router" it out with something and also try using compressed air.
