Fuel pressure: Minimum pressure not reached

Hi,

I read the error memory of my newly purchased Golf 6 1.6 l TDI Blue Motion (engine code CAYC) and found the following entry:

Address 01: Engine Control Module (J623-CAYC)
Label file: DRV\03L-906-023-CAY.clb
Part number SW: 03L 906 023 DQ, HW: 03L 906 023 A.
Component: 1.6L R4 CR td H23 8800
Revision: --H23--- Serial Number: 00000000000000
Encoding: 00114016032401080000
Operating number: WSC 01357 011 00200
ASAM Dataset: EV_ECM16TDI02103L906023DQ 003009
ROD: EV_ECM16TDI02103L906023HM.rod
VCID: 78F9D73FC3365FFE65-802C

Sure, here is the translation of the text from German to English:

"1 error found:"
10119 - High fuel pressure.
P00C6 00 [096] - Minimum pressure not reached.
Sporadically - unconfirmed - checked since last deletion.
Environmental conditions:
Error status: 00000001
Error priority: 2
Error frequency: 5
Mileage: 113,268 km
Date: 2016.02.10
Time: 16:57:28

Readiness: 0000 0000

So far, no unusual behavior observed during driving. Does anyone have experience with this error?

I particularly can't make sense of "Sporadically - unconfirmed - checked since last deletion."

Please find the complete scan attached.

Best regards,

Hello had,

It would be interesting to know the context in which the error occurred and whether the vehicle went into emergency mode as a result (i.e., whether the driver noticed it while driving).

There can be several causes for low fuel pressure, the simplest being air in the fuel system or a clogged fuel filter.

Furthermore, it is possible that the high-pressure pump is not functioning correctly, or that the fuel pressure cannot be properly regulated due to a leak or a faulty pressure regulating valve.
Finally, the pressure sensor itself and its wiring should also be considered as potential sources of error.

I would first clear the error codes and then observe under what conditions the error reappears.
You can also record data during a test drive, including the target and actual values of the rail pressure (which is useful).
For proper logging, there is a specific description, and it is not meant to be meaningless fiddling around with a few clicked measurement values.
Okay, I'm ready. Please provide the German text you want me to translate.

Best regards, Rainer.

Hi,
Sure, here's the translation:

"Another addition:"
We took possession of the car from the dealer on February 13th (which is the date of the scan). As I said, no abnormalities were noticed (although it was my wife who was driving, not me ).
"Previously, a service was performed, including a replacement of the diesel filter. Could this entry appear if air got into the system as a result? Would that resolve the issue, or are there potential consequences to be concerned about?" The timing of the entry roughly corresponds to the timing of the service.
I'm currently having trouble deleting the entry due to potential evidentiary issues (the entry definitely existed before the vehicle was taken over, so it was present at the time of the handover). I would expect the frequency of errors to increase if the error is still active. Is the reasoning correct?

Regards,
had

Read error codes with a diagnostic tool in the presence of a witness and archive the complete vehicle scan (including the full VIN)? Save the video of reading out the error memory?

Yes

If you don't have a fault message in the MFA and the car is not running in emergency mode, you can continue driving like this for now.

Best regards, Rainer.

This could potentially correspond to the error from February 10, 2016, i.e., before the takeover on February 13, 2016.

If the error reappears after deleting the data, the vendor is still obligated to provide assistance.

Definitely, you should pay attention to Rainer's instructions regarding securing evidence .
