Rebuilt the 4.8L engine have codes and problems!
 

Ok i just put together the 4.8 X5 engine and it starts up but runs like crap.

I took it to Advanced Autoparts to run codes and this is what i get:


P0201
P0202
P0203
P0204

Also Maf/vaf code. which i cleaned it and its not helping. But i noticed that it DOES NOT have the grill on it for air disbursement and i wonder if that can do it?

And P0014 i think its the ignition is Advanced. I guess i did not set it correctly it was a pain to set the ignition or i guess its called timing, on this thing.

Also I got a code that says P0013.

Also, i read something about VCT the 4 Solenoid Valves that apparently have the ability to retard or advance the timing/ignition, and one of my codes i think says i have advanced timing and also the internet says that the cam sensor code maybe caused by these VCT solenoid valves so i am suspecting that because all 4 of them have the exact same plugs and i have no clue which one goes where, if one of you have the 4.8 can you look on your engine and tell me if the short ones go on the buttom or the top, or is it different on each side like i heard that the short plug goes on top on pass side and then on the driver side the short goes in to the buttom on the driver side? Help with this would be great, and the thing is i tried swaping them different ways but i think the computer may need resetting of some sort to recognize it?

ALSO ONE LAST STUPID QUESTION where is cylinder one and where is cylinder 8 i still cant figure this out! lol :) i am totally new to the x5. I am learning a ton.

Can some one help me out and tell me what these codes are and what they mean and what i could try?

Thank you

Cyl 1 is the front of the passengers side, cyl 8 is the back of the drivers side.

When you put the vanos units back on the cams it is picky on the placement, and you have to go exactly according to procedure to get the timing right. Other than that, you probably need to get the valvetronic posotions learned via GT1 for it to know the valve lift.

Those P020Xcodes are for fuel injector circuits on bank 1, so you need to double check all wiring. The P0113 and P0114 codes show either cam advancement or air intake temp sensor from a google search, but would help to know the BMW fault description. May be time to find someone with a GT1.

Bending over and taking her to the dealer tomorrow, hopefully i can make it because the entire one half of the engine is not working.

Get a flat bed and tow her in. Why risk any damage.

You might want to stop off and get some KY. :bustingup

Tell them everything you have done in detail, and request one of the senior techs that will be best for the job (the SA will know who is good for it) and would probably be a good idea to talk to the tech about it as well. The more information he has going into it the better.

Yep, will do, i will even give him $20.00 for lunch and beg him to help me and will tell him that its been a nightmare and i have spent so much money bla bla bla and I desperately need help, please don't screw me over to hard, take it easy on me. :) and hurry up.

tow it there .. not take chances-- might cause sserious damage

You are talking about a BMW dealer. $20, try dropping a hundo his way and maybe you will get some extra luv. I don't want to bring you down, but I am guessing a bill of $1600 and 3-4 days of work. Diagnostic and fixing.

Listen to Weasel, he is a wealth of knowledge. :thumbup:

Why don't they want to help me for a decent price???!!!!!!!!!!!!!!! why is this world so cruel??????!!!!

Just got back from the dealer, spent 125.00 for them to tell me yes you have a problem with your car its huge there are so many codes we cant tell you anything, we have to run every test there is tear your engine apart we cant tell you if any of your sensors are bad, it could be anything, i asked is my MAF bad, they said we don't know, it could be caused by anything. Its $2,400 for use to find out whats wrong with your car. We have to do leak down test, we have to do compression test, take of your covers and see if timing is bad, and all that sort of stuff.

I thought that the GT1 is able to tell them if a sensor is bad AT LEAST, but i guess its not able, its the same thing as taking it to advanced auto parts and run the codes for free....

So i took her home and will do what the dealer would be doing start swaping parts taking things apart and checking stuff. For 2,400 i can replace a lot of stuff in this car.

Any ways, there it is i love BMWs

Also, who knows of a good best priced place to buy sensors? I am going to start with a new mass air flow sensor and go from there :)
