I managed to get the morning off work and had a look at the sensor that JFP and Ahsai recommended, thanks guys.

Wheel off, heatshield off.

Found the sensor.

Took off the connector.

The metal clip that I think should be attached to the tab on the sensor holder, was on the loom but not on the tab.

Looking at the wiring diagram I tried to check continuity and it checked out.

I found in post (http://rennlist.com/forums/porsche-cup-cars/771311-clutch-bleed-extension.html) that the 997 and 996 are different, 10mm and 6mm, respectively. I've written to BAT to see if they can put one together for me.

The blled nipple doesn't look like it comes as a spare only part of a slave cylinder.

I looked up a clutch slave cylinder for a 2006

There is quite a lot of different models that this fits

I think I have found an example:-

8N2837016B

996 rh door lock, Audi TT rh door lock, VW Polo rh doorlock, Skoda fabia

I do not know if a VW - Porsche cross reference exists outside of the factories.

Loren,

I know VW, Audi, Skoda, SEAT and Lamborghini use common parts. Porsche use some of the same parts. There may be some BMW and Mercedes compatibility too, Bosch for example.

Perhaps we can have a section where we find part x fits the following, there must be common things like filters, bosch sensors etc

Jchapura, That looks really neat.

Thanks, I am learning slowly.

Is there anywhere I can get a graph?

Thinking that it is probably a map, with engine speed/load/gear/temps/pressures etc.

If I can I will see if I can plot some of this stuff.

Work is currently getting in the way of Porsche time, but it does pay for it.

Is it the same as a vw?

https://m.gsfcarparts.com/658vg0070?

I think it would be useful to have a vw/Porsche parts cross reference.

Oh crud, does any one have the figures for them Variocam+?

I found this.

Or it isn't detecting a variance between two sensors and defaulting to zero. I am learning all the time, I just need to find the time to get under the car and look at the wiring. I wish I had a garage.

Learning all the time at idle -0.0959° difference is OK.

Yes but your problem is at 3,000 rpm where the angle should switch but it didn't.

Thanks I am getting it now, I should really read stuff better. 

Approx 3000

Camshaft specified angle, bank 2 -16.7031°KW.

Actual camshaft angle, bank 2 0.6094°KW.

Camshaft deviation, bank 2 0.0000°KW

So on this example 17.3125° out

From the other thread gcp's figures at idle Actual 2.0, deviation 13.97, mine -0.4141, deviation -0.5000. And +/- 6.0° is OK?

I am going to try to work out how to record both banks on the PIWIS.

Am I right that ???

°KW = Korrektur Winkel = correction angle

Thanks, I will have a read of that thread.

I found this picture, I hope it is attached.

If it is I will be looking at 14 Camshaft sensor plug,18 Solenoid hydraulic Valve Plug Camshaft Timing 20  Solenoid Hydraulic valve Plug valve lift control and 22 Ground strap.

Does any one know what the camshaft angles should be?

I am trying to pin down a workshop manual.

Sounds like you have issues with the bank 2 variocam actuator or its circuit. The workshop manual should have the actual steps. I would expect testing of continuity of the wires between the actuator and the DME, ohm out the actuator, and also apply voltage to the actuator and listen for engine change. To diagnose this further, you will need a wiring diagram.

Thanks, I have a wiring diagram.

I am working on getting a workshop manual.

You need to look at the cam position sensor in question on bank 2, which either is not sending a signal, or possibly an intermittent signal.  I would be looking at the wiring to that sensor as well, as a chaff or break can also cause this type of fault.

Thanks.

I hope this helps...  

 

P0020
Position of crankshaft in relation to intake camshaft
F NOTE
This fault is entered if there is a permanent deviation from the nominal value of 10° camshaft angle.
Diagnostic conditions
D Battery positive voltage 10 ... 16 V
D Engine idling
D Camshaft adaptation has taken place
D No fault in camshaft sensor
D No fault in crankshaft sensor
Possible fault causes
E Camshaft sensor faulty (internal phase shift)
E Solenoid valve for camshaft adjustment soiled (does not close fully)
E Timing set incorrectly

 

 

 

P0021
Inlet camshaft control
F NOTE
This error is entered if the actual value varies from the target value by between 5° und 14° of the camshaft for a duration of 2 to 5 seconds.
Diagnostic conditions
D Battery voltage 10 ... 16V
D Time after engine starts > 30 seconds
D Engine and engine oil temperature -9°C ... 106°C
D Engine speed 1160 ... 6000 rpm
D No solenoid hydraulic valve final stage error
D No camshaft sensor or crankshaft sensor error
Possible fault causes
E Mechanical fault in solenoid hydraulic valve (sticks, sluggish, blocked)
E Dirt in the oil circuit
E Sealing strips on VarioCam adjuster faulty (leaky, sluggish)
E Oil pressure too low
E Mechanical fault in VarioCam adjuster

Thanks.

As all three have suggested I will look at the sensor and wiring

I note that post drive line check the idle camshaft values have changed. Idle is a wee bit lumpier but it is still really smooth.

Further info,

Oil pressure is good, top of the gauge when running, though I couldn't work out how to record that.

Oil is Mobil 1 0w-40.

Last service at 70,000 miles, current mileage 75,000.

All advice gratefully received.

Started the car and tried to monitor camshafts on bank 2 at idle and approx 3000revs.

P0020 is back.

But not the visit workshop.

Voltage and current check, engine off ignition on.

Doing a drive line check stops the engine.

Next I cleared the codes and started the car.

Recorded camshaft values at idle.

Idles is really smooth not lumpy at all.

My friends from Renntech, your assistance and advice please.

Car is a 2005 C2s tiptronic coupe, rhd, 75000 miles. Car is the wife's and is used as her daily/shopping/kids transport.

My wife restarted the car a few seconds after parking it and got the check engine visit workshop warning.

I connected the car to my PIWIS, and got p0020 & p0021. 

I searched on here and saw previous advice to clear the code and see what happens. So I cleared the codes.

A week later it is back.

I took some photo's on my phone camera.

This will get a bit pic heavy.
