N63 intake vanos solenoid

image This N63 came in with check engine light on,,,the fault was bank 2 intake vanos during cold start,,,,so the vanos unit wasn’t working properly during cold start operations,,,,performed the test play which operates the vanos units and checks there functioning properly.image So what I found during the test is that the vanos solenoid for bank 2 intake was jamming,,,,so to remove the solenoid you have to remove or just loosen and push aside the turbo intake cooler,,,it’s not to bad to remove,,,there are just three bolt holding it in place,,,,one of the bolts is hidden and kind of hard to get to. image Once you move the intercooler,,,,both vanos solenoid are behind the intercooler,,,,the one on top is the intake solenoid,,,,,and it’s the same on bank 1,,,,, the intake solenoid on top and the exhaust one on the bottom,,,,removing it is easy just one bolt and pull it out,,,,slide new on in.image Here are the old and the new,,,new one on the right,,,,you can see the changed the design a little,,,they added a screen mesh over the holes,,,,so no dirt can clog or jam the solenoid valve,,,,because any little dirt that goes inside can cause problems.

        Hi, Thanks for the offer, it’s actually regarding the clicking noise from the wheel bearing and the SIB solution to add grease. Your comment there was that it works 50% of the time, otherwise you usually have to put new hubs. My F01 is having that exact same issue, and the dealership wants to apply that SIB-for $780!! For that kind of money, I’d rather just swap out the wheel bearings myself. If I swapped it out (seems like there is a current part that supersedes the original part, but I’d have to order new bolts since it’s threaded differently), would you still have to apply the special grease or in your experience, a new wheel bearing takes care of the issue entirely?

        Finally, I’m in Long Beach, CA and I’m also a Board Moderator for Bimmerfest.com, in case you’d like some referrals, etc. I’ve found your posts to be very informative!

      • I think your best thing is to put new wheel bearings in the car,,,,,the new updated wheel bearing and bolt seem to fix the problem,,,,no need to put any special grease with new bearings,,,,but you should clean the mating surface with some fine 200 to 300 grit sandpaper,,,,thanks for the info on bimmerfest,,,,I might take you up on that.,,,,I hope this helps

    So do you think it was dirt that caused the failure? i guess they can’t be cleaned…

    • Yes I think it was dirt,,,but also this car had low miles 16k on a 2013,,,,sometime I think the car wasn’t driven hard,,,,and things start to gum up inside the engine when it sits.

    Just wanted to say that I replaced the wheel bearings. Following the repair guide, I torqued the new bolts to 20nm, then 120nm. I also torqued the pivot arm bolt to 100nm. That was tricky since it wanted to keep spinning, so I gently jacked up the wheel assembly, which then allowed me to torque it to spec. I did not use any threadlocker since no one suggested it (and it wasn’t included in the repair guide).

    So far, have placed 100 miles and it’s super quiet, no clicking sounds and cost me less than they wanted for just applying the grease. Thanks again for your input, I really appreciated it!

    So what size is that third hidden bolt. I think it is beyond a little tricky but maybe it is just not my day.

    • All three of those bolts are 10mm head bolts,,,,this is hard to explain,,,the one hidden bolt is really hard to find,,,,it is almost tucked under the inner cooler and is set in deeply,,,look for a 10mm head bolt with a big washer on it,,,,if you have a mirror,,,,that might help to see it.

        I have a same issue but with exaust solenoid. 130308 Vanos, outlet control error, position not reached.
        130408 Variable camshaft timing control (vanos) exhaust, cold start not controllable.
        I need a pro here for this. I have a 2012 BMW 750i Xdrive. It has 29k miles on it. I recently started having an issue with 130308 code constant with checkengine light. The 130408 only poped up once. I have a snap on scanner that’s the codes that shows. The car would drive normal then it would save drive train malfunction and the car would be half power on the engine very poor acceleration. Sometimes couple days it’s all fine and one day it will do it all day. The cold is there all the time but drive train my function pops up sometimes and some days it drives fine. Change the oil in a seems to be a bit better but next day back to square one. So I have got 2 updated solenoids I have replaced 2 exhaust solenoids. Not the top ones the bottom ones i will Attach pictures. I thought it’s gonna go away but it’s the same crap. What can I do? If it would be mecanical it would be constant but some days it’s drives fine . I need to know are the bottom solenoids for exhaust.? Or do I have to change the upper ones also? Also what can I do to get rid of this problem it’s very annoying and I cant drive normal. Nice car but a biggest piece of **** i ever owned.
        After updating the pcm software to the newest update i only get 1 code now with the cold start and it drops the car in to drivetrain mulfunction. 130408 Variable camshaft timing control (vanos) exhaust, cold start not controllable. What else should i do? I allready replaced the soleboids the bottom ones for exaust.

      • Ok I probably would also replace the other vanos solenoid just to cover all the bases,,,,and also when you replace the other solenoid I would remove the new ones you put in and make sure they are clean,,,,you can clean them with brake or carb cleaner ok,,,,the new one could have gotten dirty when putting them in,,,,I have had that happen before,,,,,dirty oil can do it also,,,,,also what bank is this happening on,,,,bank 1 or bank 2,,,,, I hope this helps
