Dear diesel mechanics,

Here's an update on the injector timing and fuel consumption of my 3C engine with code MKB CBDC, currently at 199,000 km. There are no issues to report. The engine continues to run excellently with software version 8332.

It's noticeable that the injection timing becomes "worse" in winter. This could be due to the use of winter diesel, colder temperatures, or a change in driving patterns with less long-distance travel during the winter months. It's expected that fuel consumption increases in the winter.

Once a year, I use one bottle of Liqui Moly "Diesel Motor System Cleaner (300 ml) 5128". Otherwise, I occasionally use Liqui Moly "Speed Diesel Additive" and premium diesel from various gas stations. Unfortunately, I haven't recorded when I used them. In any case, the seasonal fluctuations are dominant in the graphs.

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

"Edit: The graphic showing the consumption was still missing."

Best regards,

Hi everyone,

Here are some quick details about my 2005 Audi A4 B7 3.0 TDI with engine code BKN, and 223,501 kilometers on the odometer.

It already has poor starting behavior, slightly increased diesel consumption, and a slight hesitation at idle.

According to the previous owner, two injectors have already been replaced.

I'm inclined to replace injectors 2, 5, and 6!


Regards,
Daniel.

The readings from 2 months ago... meanwhile, the positive values have increased slightly (to approximately +46 µs on cylinder 1).

Cylinder 1, Calibration Point 1: +34.8 µs.
Cylinder 1, Calibration Point 2: -0.1 µs.
Cylinder 1, Calibration Point 3: +0.7 µs.

Current mileage is approximately 85,000 km. For the last 30,000 km, I've only used "Ultimate Diesel" fuel. The engine performance has improved significantly. Before that, it was almost dead. It had no power, was constantly regenerating, and making a clunking noise. Even though the values are still increasing, it runs better now?!

No cheating here, the DPF failed at 60,000 km (at that time, it was mostly used for long distances). Currently, it's mainly driven in city traffic (short trips).

Best regards, Andreas.

The topic of "ms" and "µs" was briefly mentioned earlier. It's likely that both refer to microseconds, but with older motor types, the character set used in the computer (or by the programmer) might not have recognized the "µ" symbol. Sometimes, Americans also use "ms" to denote microseconds.
Since the injection durations and intervals are also on the order of 100 µs, correction values in the µs range only make sense.

"m for micro" is not a term that I am familiar with, either in English-speaking or German-speaking contexts.

If special characters are not supported, I know that "u" can be used as a synonym for "µ".

Greetings.
Sure.

Here is the translation of the text from German to English:

"Guste" means "gust" in English. It can also be used as a verb, meaning "to gust."

Everyone has their own observations.
We agree that milliseconds don't make sense, right?
The values describe the correction of the duration of the pilot or pre-injection phases (see also some Bosch patents) at various rail pressures, which are in the order of 100 µs (at least for the CJCD). In addition to the IMA values, this is intended to compensate for the aging of the injectors.
But you already know that.
Sure, here's the translation:

"Best regards," or "Sincerely," (depending on the context).

Hello,

Are there any findings yet regarding the evaluation?

I've also read out some values now.

Engine: CFHF
Mileage: 67600
Diesel update: YES.
Problems: No.
Feature: Mostly short distances.

"The notation x/y refers to injector x and rail pressure calibration time point y, with VCDS providing these values in microseconds."

Code:

1/1 -26,15 1/2 -14,80 1/3 -15,10 2/1 -38,90 2/2 -15,35 2/3 -18,30 3/1 -41,65 3/2 -19.35 3/3 -15,95 4/1 -33.55 4/2 -12,15 4/3 -18,55

The values seem more negative than most of the ones that have been posted so far, but there weren't many engines from the second generation of the CR series included in those comparisons.

For reference, here are the idle injection volume deviations, respectively in mg/cycle:

Code:

-0,15 0,07 0,09 0,00

Rainer once wrote: "Values below 2 mg/H are good..." which is certainly more than fulfilled here.

Best regards,

January.

After resetting the values of injector 3 and injector 4 as described in https://community.dieselschrauber.org/en/viewtopic.php?t=30733, and after driving approximately 400 km, the values for my A4 8K, CJCD are now...

Injector 1:
- Common rail pressure calibration point 1 - 18.75 µs.
- Common rail pressure calibration point 2 - 11.55 µs.
- Common rail pressure calibration point: 3 - 5.85 μs.
Injector 2:
- Common rail pressure calibration point 1 - 26.15 µs.
- Common rail pressure calibration point: 2 - 10.15 µs.
- Common rail pressure calibration point: 3 - 6.00 µs.
Injector 3:
- Common rail pressure calibration point 1 - 0.00 µs
- Rail pressure calibration point 2 - 3.90 µs
- Rail pressure calibration point: +0.45 µs.
Injector 4:
- Rail pressure calibration point 1 + 11.45 µs.
- Rail pressure calibration point 2 - 1.90 µs
- Common rail pressure calibration point: 3 - 12.40 µs.

The values for 3 and 4 increase gradually, with the value for 3 increasing very slowly.

Herbert.
