GKB MVS Transmission Data (A4B8)

Hi,
I am looking for the gear ratios (gears, intermediate shaft, driveshaft) for the mechanical 6-speed transmission in the A4 B8, where GKB is MVS.
Unfortunately, the RLF (Regionaler Landschaftsplan) doesn't provide any information, but instead refers to the ET KA (Entwicklungsplanung Landschaft).
Does anyone have any of that?
Thank you!
Herbert.

I can find this information using the vehicle's European Whole Vehicle Type Approval (EWVT) certificate. To do so, I need a photo of the vehicle registration document, but please send it to me via private message (PM) without any owner details or the vehicle identification number (VIN).

Sincerely,

Benny.

Hi,
What exactly do you need from the document? The number under the letter K?

Good evening, I saw your answer/question late. I've already figured out the translations. It was a bit more work doing it "only with GKB," but hopefully, it worked out.
Please double-check your data; if anything seems completely incorrect, I will review it again.
Your European Whole Vehicle Type Approval (EWVT) number (field "K") should be: e1*2001/116*0430* ab" 28" or a higher number.
Engine code: CJCD, 110 kW.
The internal gearbox code is: FM6B1002.
Whether it's an Avant or a sedan, it doesn't matter.

Unfortunately, I'm not able to insert a table here, so I'll have to present it in a less organized way.

1st gear = lowest gear.
2nd number = gear ratio.
3rd digit = translation of the axle gear ratio.
4th number = overall gear ratio.



1. 3,778 3,490 13,185
2. 2,050 3,490 7,155
3. 1,321 3,490 4,610
4. 0.970 3.490 3.385
5. 0.757 3.490 2.642
6. 0.625 3.490 2.181
R. 3.333 3.490 11.632


I hope I was able to help.
Sincerely,
Benny.

Thank you.
You are right about the EC number; the last block of digits is 30.
Unfortunately, the overall translation isn't quite accurate. For example, I drive in 6th gear at 120 km/h with the engine running at 2000 rpm. With a wheel circumference of 1.988 meters, the overall gear ratio should then be 1.99. Does the intermediate gear play a role in this? I only see different diameters of the gears in the overview in the RLF (presumably a technical manual or software).

What is the tire size you have?

Best regards, Benny.

Does field "D.2" in your registration document say:

B8
ACJCDF1
FM6B1002RB8KAS57MJEM1

or

B8
ACJCDF1
FM6B1002RB8K1S57MJEM1 ???

I achieve a speed of 110.42 km/h with the standard tire size of 225/50 R17 (taking into account the dynamic rolling radius). The rolling circumference for that tire size is 2007mm. Where did you get the 1988mm figure from?

Are you absolutely sure that it's exactly 2000 RPM? If you calculate everything based on 2100 RPM, you get 115.94 km/h.

Best regards, Benny.

Hi,
The tire size is 225/55 R 16, which results in a height of almost exactly 2 meters. The speed can be read accurately enough.

Is "D.2" exactly how it's written on your vehicle registration document?

I've checked it again, and the engine speed is approximately 2150 RPM in 6th gear at 120 km/h (both readings were taken directly).
Dann kommt das mit der Gesamtübersetzung von 2,18 im 6. Already went.
I'll get more details from analyzing the log files.
Thanks again, and also for your patience!
Herbert.

No problem .

Best regards, Benny.
