P0014 Horror.. Help!
 

When I start my car it gives a rough idle with error code p0014. I've changed the vanos seals, I've even swapped out the exhaust solenoid , I'm running out of options on what this code may be. BMW in my area don't know why the code didn't go away yet. If anyone had success on p0014 please reply.

CPS maybe?

Is your ICV clogged? Have you reset the throttle body adaptations recently?

I just changed the CPS, Same issue after 3 start ups.. rough idle at start up.

Have you had the codes cleared after trying something? Like replacing the CPS. Should still run okay without doing so but I have seen on M54's a rough running engine until codes being cleared after a repair. Most recently my brother in law's 01 330ci.

Sounds like you need a more detailed reader to be used... like INPA/DIS/Autologic that can pinpoint which sensor or part is causing the problem.

Did you follow the beisan systems instructions to reinstall the vanos? Can be pretty tricky and is easy to get a hair off...

Yes I did follow the steps , where can I get my hands on one of those softwares/:.. I cleared it and it came right back like a trampoline after 3 start ups..

There is an ebay seller from Romania that has the software you need. I've been meaning to order it as well. The seller has been vetted already as that is where most of the guys on the board get INPA/DIS I believe. Hopefully one of them can chime in on the specifics of it.

The guy from Romania is selling free software. You can buy the cables for 25 bucks, and download the software for free!

If you guys are interested I can post up some links.

I'm interested. Send me the links

Did you have this issue before you started changing stuff like the Vanos Seal or did you have this issue after you started changing parts.

If you having this issue after your repairs, it is something you probably did. Go back and re-check your work. Follow any procedure that is outlined for the parts replacement. Don't assume that you can just take out a part and put back in a part.

If you were having this issue before replacing parts, you need to do a little bit of more diagnostic. A DTC will point you to a problem the computer is seeing, it does not identify a parts to be replaced.

In your case, the cause of a P0014 DTC trouble code may be caused by one or more of the following:

Incorrect camshaft timing
Wiring problems (harness/wiring) in intake timing control valve control solenoid system
Continuous oil flow to VCT piston chamber
Failed timing valve control solenoid (stuck open)

Here are the links for the cable and the 20 pin adapter. Most e53 owners will not need the 20 pin adapter as you can acess all modules through the obd port on 2001 and up. Do not install the drivers if they come with them. I will start a new thread on complete installation for edibas, INPA, ncs, and ISTA, tonight. In the mean time you can purchase the cables.

Ordered it, I'll be waiting on the write up later. Thanks man

Hey guys, I'm the guy that did all of the work on this truck . He had error before doing the vanos seals. Upon removing vanos, bothintake and exhaust pistons were very sloppy and in fact just fell out of Vanos unit. After I replaced the seals, truck still had rough start and code. I scanned it with GT1/ IPNA and it said something like exhaust camshaft reached limit. Exhaust actuator "B" after going through test schedukle in GT1 , it recommended new vanos unit. WE tried swapping out Exhaust solenoid (checked spring inside vanos,ect) ,we tried changing camshaft position sensor, still had code . Yesterday, I took the vanos apart again and swapped his intake and exhaust pistons to another vanos unit I had. I used 2 cans of brake cleaner and blew out every oil passage in vanos unit. After I put everything back together, the truck fired up and sounds great. He picked the truck up this morning and the code hasn't come back . (fingers crossed that did the trick )

This guy "Hollywood516(James)" Does amazing work, Drove 30 miles after i picked it up and it feels like a new car, my car hasn't run this smooth in months, I'm more than happy the code is gone.
Sucks that it was such a headache to get rid of but all is well, Now i can start the sound system project :p.
Thanks again James, if you have any engine or suspension work in the NYC area he's the guy to call, he has an answer for almost everything and he won't kill you with price.

I guess the old vanos unit was so worn that it didn't seal right, that is why the intake and exhaust pistons were so sloppy in their bores.

The pistons were sloppy from the bad seals.. When i replaced the seals, everything seemed good. I think there was a problem with the rod and spring at exhaust solenoid. I dont think his truck even has 90k miles on it . The Vanos unit I used had intake and exhaust solenoids and CPS still on it.... just sucked because i had to basically do vanos twice...

Could of been a bad seal install the first time. The seals are supposed to be installed in a particular fashion and then "broken in" for the first couple hundered miles.

Glad you got it worked out!

I have done about 25-30 vanos rebuilds/seals since i started working on BMW's . They are fairly simple devices that do a complicated job. Im happy it worked out also because we were running out of options and BMW was goin to charge him $1400-$1700 for a new vanos :thumbup:

The "Sloppy Piston" could have worn the bore enough that even with new seals, it was not enough to prevent the new seal from sealing correctly.

^agreed^^
