P1358 Camshaft Adjustment error

[aveerdonk]

Guys,

I have a 2001 996TT with 100.000km/~60.000miles.
Last week I had a P1358 without any strange behavior. I cleared it and the next morning it stuttered a bit in 2nd gear when leaving the house, without throwing any errors. I returned immediately and started studying all the possible posts related to Camshaft Adjustment Errors (P1358, P1357, P1348, P1349 etc…).


My angular values are as follows:


Cold
Idle: ~850rpm
Camshaft position 1 deviation: -3 degCrk
Camshaft position 2 deviation: -5.2 degCrk
Actual angle for camshaft, bank1: ~0.06 degCrk
Actual angle for camshaft, bank2: ~0.15 degCrk

Warm
Idle: ~850rpm
Camshaft position 1 deviation: -2 degCrk
Camshaft position 2 deviation: -4.8 degCrk
Actual angle for camshaft, bank1: ~0.06 degCrk
Actual angle for camshaft, bank2: ~0.15 degCrk

This morning I disconnected the (when in the car right hand bank, assuming #2) bank #2 solenoid or as called in the parts list “actuator valve” item#25 996.105.301.71. Expecting to get a P1358, instead I got P0022 and disconnecting item#23 I received P0023.

Not yet being able to reproduce it and reading about 0-6deg allowable range, my best hope is that the error (& stuttering the day after) was dirt?? and plan to do an oil & filter change, even though I’ve only done 2000-3000km (~1500miles). I’ll examine the oil-filter for any particles and will post the result.


Now to my questions….
Is there anything I can simulate to trigger the P1358 and better understand where it comes from ?
What would you suggest I do, without taking too much apart ?

Thanks in advance
Regards
Arnaud

Sorry to revive this topic but I am having the same issue.  But I found some metal when I pulled my actuator.  I'm praying I don't need a new motor.  Has anyone solved this issue?

What kind of metal is it (ferrous or non ferrous)?  Makes all the difference..............

[Tuner1984]

Ferrous.

That is not good.  These engines can shed aluminum without a lot of concern, but ferrous debris is a sign of something more serious.  I would not be driving a turbo around that has ferrous debris in the engine as that Mezger lump is a bloody expensive unit to replace.  You need to find the source of this ferrous material and fix it before it tears up something very expensive.

Yeah its like one of the worst situations you can have :(.
