- I fixed it! Such an accomplishment to diagnose such a problem and then go fix it:). I am a happy camper to say the least. This video will show you what to do if you get the 2A7A code on a BMW engine N52 or N52, possibly the N54 too.

Where did you get those bolts I have the same problem and I’m trying to replace them but I can’t find the bolts anywhere
@@JonathanGonzalez-gh6nf the dealership has them
Huge flaw--> wearing a ring on your pointer finger ✌️
🤣
Great video sir! How many miles did you have in the car? I have the n52 2011 bmw 328i. I’m taking the car to bmw for this recall repair in a week. I got 132k on mine.
Dont use steel bolts. Use aluminum. The head the block the cam adjusters are made from a magnesium aluminium alloy. Magnesium will corode and crumble against steel stainless steel brass cooper titanium. So aluminium is the only option on these engines 😢
Thanks bro great info!! Happened to me today!! Repairing it myself
Right on man. Good luck.
im ready to trade my accord 2007 manual for 2011 bmw 128 auto with 90k think i should do it?
Dude you were super lucky, good stuff
What happens or needs to be done if they vibrated out or sheared off?
It's actually a recall but no buddy knows about it. I had the same problem and they fixed it for free
It’s only a recall for SULEV vehicles. And the mileage of the warranty varies by state. If I lived in California, this would of been covered. The recall was for the actual bolts, which were only covered/replaced under warranty according to my knowledge.
It would be helpful if someone knows at what mileage the issue occurred.
Chief,
Did you have to loosen the Tensioner?
Did you loosen the Tensioner 1st b4 taking off the BiG bolts or it doesn’t matter which one goes off 1st?
That's what hapens when you go from your Honda's reliability to the BMW's not so reliable and expensive. Reminds me of my old bmw motorcycle and the "fun" it gave me :))
Yep.
The higher maintenance is expected, but these bolts imo, are a design flaw. Live and learn;). This is my 7th BMW.
Those vanos units are parts supplied from a manufacturer to BMW ...not built by BMW and multiple other manufacturers are suffering similar problems including Toyota..ME/BE ..Audi so figure it out !! in all cases it's the supplier that fails to meet a automotive manufacturers specs
Hello did you put the pin that goes into the flywheel ? Or did you just lock the cams
Hey mate great video I'm about to do mine was it easier to take the cam sprocket off then remove/put bolts in or can it be done without removing sprocket? because a few bolts on mine actually sheared off on the intake side only. And also what did you torque the vanos bolts.
How did you end up doing it brother to take off sheared bolt
Hi chief, Do you have the part number on those revised bolts? I can’t see the complete numbers in your video.
Thx
Congrats dude, Saved another gem of an engine!
Gem???
ONE LAST QUESTION CHIEF:
Did you have to LOCK the flywheel under the starter area?
Thx 🙏
i recently did my valve cover and gasket because of minor oil leakage. i upgraded to a mitzone aluminum valve cover. i also did coils and spark plugs because i was getting a multiple cylinder misfire. i have everything back together and it runs good for 3 seconds then its a rough idle. im not getting a rattle/diesel noise. would you think i need the vanos sensors? or should i rip my valve cover back off to inspect the vanos gears like your vehicle? the 2a7a code comes back everytime.
You need to check the cam bolts for sure if it is an n52 or 51. Not sure about the sensors, but the bolts are a design flaw.
thanks ill use your link for the tool
Lots of post i see only 1 bolt shear off and they get a whole new vanos unit, could you just extract the broken bolt and replace them keeping the original vanos unit?
Yes. But you still need to drop the pan to retrieve the bolt.
Torque specs for those bolts are 6Nm +60 degrees
Link on bolts
Did you have an engine code on this ? Does anyone know or can help me on this had camshaft sensor light on mine replaced it and nothing could this be my problem
Yes I did. I have videos on how to fix it and what the symptoms are.
where can i get the bolts?
how about 2A9A car just turns over bought it on a gamble hoping its just intake cam sensor any chance w your research already u may have any info thanks left ya a like
Hey, just wondering I have the same code on my bmw, and I am getting stutters and the car sounds like it wants to shut off when stopped at a red light. My question was how long did this take u to do?
I think it took me about 8-10 hours.
What happened? What was your symptoms why you opened the engine? What did it do? I have the same ride.
My car just died, won’t start now and it is showing P0365. 2 Camshafts and crankshaft sensors replaced.
Still won’t start. Help help help chief.
Rough idle. Sounded like a diesel. I have two videos on this. Go watch the other one they are linked. Your issue sounds different. Might be a crank position sensor.
@@OregonMotorcycle I already replaced the crankPS. Still won’t start. Hesitates. Only one or 2 cranks and then battery resets.
It was idling fine in my garage and then died suddenly.
@@simplelangperorock check the fuel pressure.
@@OregonMotorcycle okay, I don’t think I know how to do that. I will look it up how. Help?
@@OregonMotorcycle thanks chief
Thanks for the video! How many miles on this engine?I have a N52 but low milage so wondering if this will need to be done soon.
I think around 125k. It sure exactly. I have133 now and just replaced the water pump;)
Did you do anything to lock the crankshaft at TDS? I am replacing my cam sprockets Thursday and I plan to just lock the crank where it is when the cam tool is installed.
No. I just turned it to top dead. My tool came with a lock…. Long as your careful it’s not that bad. Once the chain is off, the bottom won’t move.
What was wrong with the sprocket
The bolt heads snapped off of the bolts that hold the variable valve timing sprockets together. A common problem. The replacement sprockets came with steel bolts.@@rauldeleon6728
We’re the link
it is a recall now!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Damn bro you like that exclamation mark huh?
If I was a California resident, yes this would have been covered. Do your research.
Hey Oregon biker, so these new upgraded bolts are like plastic I have them from the dealer. What do you think about putting steel bolts instead? Did it work? Or could that be dangerous?
Pretty sure the ones I got from the dealer were metal. The original bolts are aluminum. I was gonna get regular metal bolts at Home Depot if I couldn’t get these in time from the dealer. So yeah it should be fine.
@@OregonMotorcycle thanks get saved through Jesus Christ!! Invest in your real retirement plan. So so dearly important. Read the book of Mark in New Testament. Much love!!
Link bolts ?
hey what are the part numbers for the new bolts?
Should be in the vid or the fox video. I made sure to put them in the video.
Hi there I got the p0015 code (other DTC p2A7A and p2A87) on my N52, car runs smooth and fine, I dont feel anything wrong when the car is idling or accelerating, dont feel any loss in power, replaced both vanos and the code still there, could it be the camshaft position sensor itself? Also I watched your symptoms video and mine had nothing like that
Yeah I would check the sensors.
Your timing might be off too.
What ended up being the problem bro
@kennyus2000
@rauldeleon6728 the bolt on the sprocket backed out
@@kennyus2000 did u replace sprocket or bolts
So did you use steel Home Depot bolts instead?
No
Interesting BMW sent you steel bolts. Can mix steel with aluminum, hence aluminum bolts all over the car.
The block is aluminum. The cams and gears are steel.
@@OregonMotorcycle you’re right. I forgot about that. What was BMW thinking 🤦🏽♂️. I contacted a local dealer and they told me my 2011 328xi has the bolts recall, but.. they said there’s no solution for the bolts at this time. 😳. I said, there is, so I guess they don’t want to do the work. I rather do it myself. And I have the oil sweat between the head and block between the solenoids and the coolant flange. It’s said the bolt under the intake manifold is the culprit, but the bolt head is in tact. So, I’ll have to buy new four bolts and retorque the front of the head when I replace the vanos bolts.
@@iamurnamann8662 my car is a sulev. If I lived in California, this repair would be under warranty. Along with my 800 dollar radiator that’s leaking now🤣
@@OregonMotorcycle mine is a sulev as well. Lol. I did find the radiator for 120.00 and the Mercedes EAC sensor that would need to be modified with the BMW connector for 90.00. I’m sure my radiator will fail as soon as the sulev warranty expires. Lol. I’m in NY so the sulev warranty is covered, but after what the dealership said about the vanos bolts, I rather do it myself. I just don’t trust anyone anymore. And the PO didn’t take care of the car. So I fixed it all up, running like new so I’ll be damned if I let some dealership who doesn’t want to work touch my car. Great video btw. I forgot to mention that earlier. Lol
@@OregonMotorcycle one more thing. Change that coolant flange, where the coolant flange is fed by the OFHG asap. That plastic flange fails. Get aluminum flange for 12 bucks. 👍🏽
Glad you were able to fix it yourself. If those bolts were to break off, would you have need a new engine, or Just drop oil pan and fish them out?
The procedure is to drop the pan and fish them out.
@@OregonMotorcycle actually i have these really small flexible magnets from v8 tools called the mighty worm you could possible fish it through the oil pan to retrieve the broken bolt heads
@@izakwasserman2887 But the fasteners are aluminum?
@@mikehermesmeglio pretty sure the new ones are not alluminum
@@izakwasserman2887 That's true. The new ones are not. But if they were new non aluminum fasteners then you wouldn't be fishing them out of the oil pan. My point was that your magnet tool is not going to stick to an aluminum fastener.
Aye, Thanks for this video! I just had one question, Would you know how many hours this job calls for?
You didn't need to remove vanos to replace those vanos screws totally point less .I have done that procedure as a tech hundreds of times ... your total procedure is not incorrect and we'll done !! but unnecessary
I was kind of thinking the same. At least for the exhaust side…. At first I was planning to replace the whole units.
Hey brother what to do if they are sheered how to extract them
@@rauldeleon6728 pull the oil pan.
@johnboutsikos6049 do you need a long shaft T45 to remove those bolts? It's a lil tight in there with my regular T45. Thanks man
bolts part number please?
You can see the number in the video.
Good video but next time no music in the background please
