Mini N18 Fault Codes 2C58, 2DA2, and 2DA0 • I Need Help!

The 2014 MINI Cooper S R60 Countryman N18

Greetings everyone, These engine codes are giving me trouble right now.


2C58 - Control of charging pressure: Turn off as a result
The angle offset with respect to the crankshaft outside tolerance is 2DA0 for the intake camshaft.
Angle offset with respect to the crankshaft outside tolerance (2DA2)—exhaust camshaft

The codes are cleared.
I get no problems when the engine is idling or revved up to 2500 rpm, but as soon as I start driving and take off the gas, the trouble codes start popping up again.

A new turbo, head gasket, valve stem seals, timing chain, and two new Vanos solenoids were recently installed on the vehicle.

The timing and tool alignment have been double-checked.

Changes to Vanos have been rolled back.

Compression on each cylinder is around 180 psi, which is good for the engine.

If you could assist, I would greatly appreciate it.

Was the TC a complete FAI or OEM BMW kit that came with all the necessary guides and a new tensioner? The solenoids must be of the BMW or Pierburg variety. Just wanted to give you a heads up that most of the material you see on the internet is crap and won't work, so there's no need to worry about whether they were or weren't. It seems that out-of-timing problems are prevalent in these codes.

To be quite honest, I think 180 psi is a little low for a turbo; it should be closer to 200 psi.

I replaced the tensioner and guides on the fake timing chain, but I left the cam sprockets alone. Since I recently purchased a regular chain kit. Before I started working on the engine, I never had these codes. Even though the engine only required a new head gasket, I decided to change the chain nevertheless.

After double-checking the timing, I can confirm that both cams are in sync when the crank is locked and the locking tools for the camshaft are exactly aligned. The engine had to run for some time before this inspection could be done.


I installed two Febi Vanos sensors.

I'm grateful for the update, kk. Your double-checking and confirmation that the timing is perfect is greatly appreciated (y)

Your utilisation of high-quality parts is commendable. Since you neglected to replace the vanos sprockets and the rectang rings (gaskets) at the cam ends, I'm wondering if that's the source of your issue. The replacement chain's lifespan will be diminished due to the old sprockets wearing it down rapidly. Without checking the real-time data, I'd venture to say that the sprockets are Maxwell-worn and the rectangs are past their sell-by dates. Examine the desired and actual cam locations to determine the extent of the disparity if you are unable to obtain a more advanced scan tool. You may use that information to identify the sprockets and rectangs.

What is the process for altering the rectangles? I might as well do the new Vanos gears since I'm going to use them anyway.

[Motoman]

Each camshaft requires two genuine BMW parts, and you can only get them from an authorised BMW dealer. One day after receiving them, immerse them in motor oil. Changing them is a breeze; simply remove the old ones using a pick, apply oil to the cam ends, then carefully push the rectangs into place using a plastic pry.

[EatSuru]

How does the new set of cam rings that BMW offers compare to the previous ones?
