also engine is shaking sometimes not much and currently only code is in slave ECU CDKPH Nockelwellengeber Einlass which seems to be camshaft sensor inlet
Yes, correct, this means indeed camshaft sensor inlet. These sensors break down, replace them and see what happens.
Well, INPA cannot communicate with cruise control and DSC. Let me double check how I've installed fuses and let me double check the actual fuse.
Are you able to communicate with them directly in INPA? If you try to connect to those ECUs?
I don't think that you have an power problem, I think it is can problem. DSC and ACC modules are a bit special, they are connected to "front termination resistor", behind the IVM, so to speak, check this:

And this resistor is located there:

It is like an extension of the CAN bus.
Something else: an E65 reacts with very funny errors when the battery is somewhat discharged! Please see how many volts your battery still has and charge it if necessary.
Speaking of wiring is WDS_NG URL shared anywhere or is that a sensitive matter? How do we share WDS_NG with Bill and Simon?

Does anyone have N73 workshop repair manual by any chance because I do not
Wonder if intake cam replacement is an engine out job or not. I can kind of see the connector behind those two hoses but no idea how much stuff to take apart.
Did I mark bank #2 right?
Acorn under engine cover a bit scary.

Intake cam replacement should be possible with engine in, just a question of why?

It would be nice to address the check engine light and to get a false sense of comfort from knowing that at least the chain is not loose enough for ECU to throw a code. But it's only worth it if under X number of hours and considering how tight everything is my preference is not to dive blind.

Bill should be able to advise on this soon as he is going to have to do it.
He found a lump of chain guide in the sump yesterday.

Well that was wrong end of engine. On N73 cam sensors are on the back side of the engine, pretty amazing access once engine bay partitioning wall is removed

That was easy, intake cam position sensor bank #2 replaced, piece of cake, INPA is no longer complaining about that one.

Man in the middle status update: it moves but also gives me transmission fault on gauge cluster. I have no idea what am I doing wrong or what other packets are needed.
"A lot of DSC/airbag/brake lights on the dash. Feels like power steering is not working."
did you get that fixed?
i bet your steering fluid is low
check that fluid level.
the DSC is run by the power steering pump.
i had a mega leak in the lines. so it killed the steering and DSC when the fluid leaked out .
"A lot of DSC/airbag/brake lights on the dash. Feels like power steering is not working."
What was systems have in common is bright on the same sub-harness where I am cutting wires for my transmission hacks. My understanding is that this is about lack of CAN communication not mechanical. For now it works better for me to have these systems broken actually so I am keeping as is for now.

wow the left side of the engine is happy! things are so great that I've invested into a full tank of gas, and seriously consider replacing a license plate lamp. Ohh, and an oil change.
hello P0459 | Evaporative Emission System Purge Control Valve Circuit High
I absolutely love how two of these 7512582 are right next to each over with perfect access! So easy to see that one beeps with DMM while the other one does not.
Is fuel supposed to leak when I disconnect? Is my canister not doing the canistering?
Also just a sad picture.

It is possible to remove the camshaft without removing the engine. But why do you want to do this?
What do you want to do?
The bench markings are correct. Bank 1 is on the passenger side, bank 2 is on the driver's side.

If the membrane is closed, the fuel can flow directly into the tank ventilation, which is not particularly tragic. However, when the engine is warming up, the tank vent valves (TEV) are closed and fuel is accumulating in the system. When the TEVs are opened, the fuel flows into the intake manifold and is then sucked into the engine and burned. However, depending on the accelerator pedal position, the engine reacts differently to a mixture that is far too rich. If you are "crawling" (rolling slowly, no throttle at all), the engine will die, but can be restarted immediately. When you're about to accelerate, there's a firm jerk, like turning the engine off for a second and then back on. This happens two or three times
Let's switch to something way more fun for a second. If we go for internet points maybe a video of drifting? E65 definitely has open diff and it sounds like diff has to be welded for those application and looks like a trivial thing to weld. A more interesting challenge would be keeping car in gear.
We know that E90 is related to my E65 in terms of CAN traffic. We know that E90 used 6HP. I wonder if I can run my E65 in Steptronic MS mode assuming "Steptronic MS mode" means what I want it to mean?

I am an idiot, I have manual mode on my car, I just need to put it back together and try it.
Both buttons in the front of steering wheel are for downshifting. There are two more behind the steering wheels. Those are for upshifting.

you are gonna WELD the diff?
that is pretty hardcore
dropping the rear subframe is a pain in the ass
i just did it
as the guy in the video said
"AAAGGHHH... i can't believe its finally out"
At the moment I am considering options. Considering the chance of engine blowing up on first drift attempt I should postpone actual welding and actual revving for until rusEFI N73 drive around the block.
This will not last Andej. It took us (N73 drivers) years to find the right material... This Magnaflow scrap you can send right back. As I said, for 100€ you get from me a complete repair kit for the both high pressure pumps.

I am trying to get 80% of the results at 20% the effort, after all I only need this car to last 500 more miles. Please forgive me for the neandertal approach to a very nice piece of engineering
I have too much random oil around my place I will put fresh oil into the car and drive it just for 50 miles and see what comes out.
For better context let me really ask Bill to have a thread on his 760

what happens after 500 miles? you give it the heave-ho? or it will be destroyed for science?
you can just drop the oil pan pretty easily ( for a german car)
and look inside. before you put fresh oil in the car .
you just need a new oil pan gasket -- $12
the synthetic 5W-30 oil is like--- 10 quarts--- for $60

New used ABS controller installed, still waiting for that new used EVAP solenoid. Next step oil change with wrong oil and $5 just for 50 miles, and then less wrong oil and nicer filter. Also need to do transmission fluid change I guess?

tranny fluid change needs a new pan/filter too-- like $60
plus the fluid is expensive ...
and you only get a few quarts out by dropping the pan... it holds like 10 total in the tranny cooler, torque converter, etc
and you need a special tool to pump out the remaining 8 quarts
how much longer are you keeping this machine?
if it shifts okay for now,
and is not low...
then... perhaps wait?

I do not have an answer, there is a wide array of possibilities from daily driver to abusing for marketing purposes. But even for drifting experiments my preference would be to do easy maintenance like transmission drain and fill.
Castrol Import Multi-Vehicle Automatic Transmission Fluid is mentioned more than once in the comments on the video below.
