These codes were read using the Ross-Tech cable on a 2005 Audi A6-42K miles.

1 . Address 01
fault code 18975 - low pressure fuel sensor (G140)
intermittent P2543 - 009 open or short

2. Address 61: Battery Regulator
4 faults found:
02273 - Stage 2
02276 - Stage 5
02274 - Stage 3
02277 - Stage 6

I cannot find these codes on Rossp-Tech's website.
I erased all of them but wanted to know what these are.
the car seems to run OK.
At 40K miles, I replaced all the spark plugs, filter, a/c filter, brake fluid, antifreeze. wanted to replace the auto transmission fluid, but that cost is too high at $36 per quart, there is no substitute for this oil, only dealer.
Any suggestions would be great.

It sounds like low fuel pressure sensor is bad. The engine control module will send a fixed amount of PWM signal to the fuel pump control module if the sensor is bad, and the car will be OK to drive.
Low fuel pressure sensor designation is G410 not G140, and it is updated to -K level: 06E-906-051-K.
I use this company for INTERNET order to save some money if I am not in hurry (I have no financial or personal interest with this company).

See the picture for the location of the sensor. The picture is from 2006, and some engine has sensor on top of high pressure fuel pump. It is very easy to replace it. Needs 24 mm open-end wrench.

Purge the fuel in the fuel line before removing the sensor by following the direction in this thread:

Thanks a bunch, audibug !!!

bballfreak,
Glad to be a help.
Please update your result so we all can learn.

Audibug, could you read these codes for me?

01316- brake system ECO read trouble codes intermittent.
18061 - Read codes from ABS-ECU P1653 Intermittent
01435 - Sensor 1 brake pressure G201 not a plausible signal intermittent.

I have just replaced the front brake pads to ceramic pad within 2 months, the rear is still the normal pads. Also, the 2 left tires on the left handside should be replaced soon, while the 2 right tires are almost brandnew (don't ask me why, it's because of me, not the car). Could one of the two things caused all these codes to pop up?)
Thanks

I replaced mine as per the instructions of AudiBug and was easy and took like 5 minutes to replace this part.
I erased all the codes and now will drive the car and see if the
code comes back again.
Thanks, audibug!! u da man!!

Hope that fixed the problem for good.

I changed out the low fuel pressure sensor and cleared the codes, but continues to show up after driving. Cleared it like 5 times but comes back.

bballfreak,
Sorry to hear that G410 didn't fix the problem.
It seems that you have VCDS.
Try to see the pressure signal using measuring blocks and VC-Scope.

Select -Engine module => Meas. Blocks

Change group numbers to 103, 106, 140, and 141 to view fuel pressure related data.

Use VC-Scope and/or Data Log to view and capture the data.
According to the freeze frame, the code was set when you started moving from idle.
