Hello everyone,

I am reaching out to this community because I haven’t been able to find a definitive answer in the local German forums and I’m feeling a bit stuck. I am working on my 2003 Mercedes-Benz E 220 CDI (W211).

Vehicle Details for Reference:

The car is an E 220 CDI with the 2148 ccm engine (110 kW / 150 hp), first registered in November 2003. The VIN starts with WDB211006... (Pre-Facelift). It is a Euro 3 model, equipped with the 5-speed automatic transmission (722.6).

The Problem:

According to the Mercedes EPC (Electronic Parts Catalog), the correct torque converter for my vehicle should be A2092500902. However, upon disassembly, I found that my car is currently fitted with torque converter A2112500402 and a flywheel (drive plate) with part number A6110320147.

I purchased the new converter (A2092500902), which originates from an Inline-6 cylinder engine, but it does not fit my current flywheel. The bolt pattern/alignment does not match.

My Questions:

1. Is it possible the EPC is providing the wrong part number for my VIN, or do I need to upgrade the flywheel to match this specific converter? If an upgrade is required, what is the correct part number for the matching flywheel?

2. Since this new converter (A2092500902) originates from a 6-cylinder engine, will I face any performance or driveability issues (such as a different stall speed) when installing it on my 4-cylinder 220 CDI?

Note: The car is scheduled for a Stage 1 tune shortly, including a DPF and EGR delete, so I am looking for a robust solution.

Any technical insights or part number cross-references would be greatly appreciated! Thank you!

On the nemigaparts.com website, the following are shown for a 211.006 E220 CDI.

Torque convertors:


Flywheels.


I've noticed part numbers tend to "cluster" around the intended use.
A curious note to mention, you mention part number A 611 032 01 47 as your flywheel; I'm not finding that in this parts catalog (the parts number search feature doesn't work). In the Nemiga parts catalog, part number A 611 032 xx xx refers to a washer mounted to the ring gear. Two flywheels A 646 030 xx xx listed for the 211.006 model.
Three varieties of torque converters are shown; one from the W210 series (A 210 250 06 02), two from the W211 series (A 211 250 04 02 and A 211 250 11 02) and one from a W209 series (A 209 250 09 02).






Looking at the W209, CLK 220 CDI, 209.308, the following are listed.




The 211.006 and 209.308 do share a common flywheel part number ending in 05 05.

I do not know if this helps but I hope it points you in the correct direction. I wish I could hook you up with my Mercedes parts guy in San Antonio; he has worked minor miracles for me when researching parts.

Assuming by your statement, "haven’t been able to find a definitive answer in the local German forums", I assume you are in Germany. If so, may I recommend a road trip to the village of Trippstadt in the Rheinland-Pfalz to visit a pretty little place called "Karlstal". Used to be one of my favorite walks during the years I lived in Trippstadt.

Hello,

First of all, thank you so much for the detailed research and the warm welcome! It’s great to see someone who knows the area around Trippstadt and Karlstal – it is indeed a beautiful place.

Regarding the technical side: I have done some further investigation and took some photos to clarify the situation (see attached images).

The part number A6110320147 I mentioned is actually the ring gear / drive plate (Mitnehmerplatte) where the torque converter is bolted onto. Based on my research and the physical parts I have in front of me, the part numbers listed in the standard catalogs don't seem to match my current setup.

I am attaching two photos for comparison:

• Image 1: Shows the mounting method and bolt pattern of the torque converter currently installed in my car (A2112500402).

• Image 2: Shows the mounting points of the new converter I received (A2092500902).

As you can see from the photos, the mounting points are physically different, which is why it won't bolt onto my existing ring gear. It seems I am stuck between two different "generations" or versions of the 722.6 drivetrain setup.

I would appreciate any further thoughts on which specific ring gear would bridge the gap between my 220 CDI engine and this 6-cylinder converter, or if this swap is even feasible given the hardware differences.

Thank you again for your help!
