what is the usual cylinder pressure if 36.3bar is outside of parameters?
Depending what the engine is doing - between engine braking and full blast - from 21 up to 160 bars have been observed. Typically on idle 40 bars.
Implausible signal - indicates that data received from the sensor is out of normal working envelope, either because of (1) the sensor itself being faulty or (2) a fault somewhere else is causing the engine to run out of the spec.
P13D6 00 [236] - Implausible Signal MIL ON - Intermittent - Confirmed - Tested Since Memory Clear
So an engine light is ON - is it flashing coil or the emission light (engine symbol)?
I've recently purchased VCDS so big boy pants on and plug it in!
Congrats!
Well, if you would like to take full advantage of VCDS capabilities you could do the following. I'm more than happy to look into the data.
1. Engine's blockmap data (engine idling, preferably "hot")
2. Recording of selected engine parameters
Ignition ON, Stop/Start off, put the Seat belt on (needed for Stop/Start to work)
Check fault memory
VCDS - Select Control Module - Engine - Fault Codes - Save
Return back to Engine main menu, select Adv. Meas. Values
Tick the following
IDE00021 Engine RPM
IDE00190 Charge air pressure: specified value
IDE00347 Air mass: actual value
IDE00351 Main injection: start of activation
IDE00472 Mean injection quantity
IDE00589 Fuel pressure
IDE00594 Absolute intake pressure
IDE04090 Exhaust temperature bank 1
IDE04685 Setpoint generation interior torque
IDE07738 Charge air cooler inlet: pressure sensor 1 bank 1: raw value
IDE07742 Cylinder head: pressure sensor 3 bank 1: raw value
IDE07757 Exhaust recirc.valve 1 bank 1: posit.feedback - Actual value
Tick "Group UDS requests" - by 7 (verify all values are alive).
Click Log - Start
Start the engine, let it warm a bit (unless warm already) on idle, minimum for 30 seconds
Floor it (quickly) to the max (2500rpm) for 10 seconds
Let it idle for 10 seconds
Floor it (quickly) to the max (2500rpm) for 10 seconds
Let it idle for 10 seconds
Shut it down by Stop/Start (if works), otherwise turn ignition off and immediately (but let the engine shut off) back on so VCDS can keep on logging.
Stop VCDS logging etc.
Check the fault memory - under Engine - Fault Codes - Save
The logfiles will be in folder ...VCDS\Logs
Please post the logfiles.
3. Recording of selected engine parameters while driving (perhaps later)
Basically just a repeat of the "case 2" above but driving around. At some point apply full throttle preferably going uphill - starting at 1500 rpm finish at 2000 rpm. Also a long (at least 10 seconds) engine braking would be nice to capture.
EDIT: attached preformatted file for the VCDS Adv.Meas.Values (case 2) - Please remove the .PDF -file extension so the file will become
cylpressure.u01
- click on top/left corner to load the selection... (cylpressure.u01)
