Dear diesel mechanics,

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

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

Once a year, I use a 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. Seasonal fluctuations are the dominant feature in the graphs.

Edit: The graphic showing the consumption was still missing.

Best regards,

Abnormalities: Currently, the particle filter loading is exceeded.

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 some slight idling roughness.

According to the previous owner, 2 injectors have already been replaced.

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


Regards,
Daniel.

Engine code CFFB 2.0 TDI CR, mileage 85,000 km.

The readings from 2 months ago... meanwhile, the positive values have increased slightly (to approximately +46 µs for 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 3,000 km, I've only used "Ultimate Diesel" fuel. The driving performance has improved significantly. Before that, the engine was almost dead. It had no power, was constantly regenerating, and making a knocking noise. Even though the values are still increasing, is it performing better?

No cheating here, the EGR valve failed at 60,000 km (at that time, the car was only driven on long distances). Currently, mostly used for city driving (short distances).

Best regards, Andreas.

The topic of "ms" and "µs" was briefly mentioned earlier. It's likely that both refer to microseconds, but with older engine types, the character set used when creating the program might not have recognized the "µ" symbol in the computer (or in the programmer itself). Americans sometimes also like to write "ms" for microseconds.
Since the injection durations and intervals are also in the range of 100 µs, correction values in the µs range are the only ones that 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 recognize "u" as a synonym for "µ".

Greetings.
Guste.

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 times (see also some Bosch patents) at various rail pressures, and these are on the order of 100 µs (at least in the CJCD system). The intention is to compensate for the aging of the injectors, in addition to the IMA values.
But you already know that.
Sure, here's the translation:

"Best regards."

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: Primarily short-distance routes.

"In the notation x/y, x represents injector x, and y represents the rail pressure calibration time, 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 CR generation included in the comparison.

Here are the idle injection volume deviations, in mg/cycle, for reference:

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,

Jan.

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

Injector 1:
- Rail pressure calibration point 1 - 18.75 µs
- Common rail pressure calibration point 2 - 11.55 µs
- Rail pressure calibration point: 3 - 5.85 µs.
Injector 2:
- Rail pressure calibration point 1 - 26.15 µs
- Common rail pressure calibration point: 2 - 10.15 µs.
- Rail pressure calibration point 3 - 6.00 µs
Injector 3:
- 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
- Rail pressure calibration point: 3 - 12.40 µs.

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