The one for my car looks like this one.

Part number 8E0 260 805 S (Denso 7SEU16C)

<img src="http://www.jovinauto.com/wp-content/uploads/Volkswagen-Golf-V-7SEU16C.JPG">

This one is part number 8E0 260 805 BJ (Denso 6SEU14C)

Now my car is a 2004.5

I went to the parts department and they brought out the 8E0 260 805 BJ

So will it bolt up fine and work?

Here is a chart I found www.frigair.com which lists both part... and of course my car bridges when they swapped units.

But I did stay at a Holiday Inn Express once!

Hope some of this helps you. I'd go with whatever came off your car.

I assume that since proper oil capacity is critical to performance/longevity of a/c compressor, different part numbers are matched to the specific vehicle a/c system -- different compressors will hold different amounts of oil and different vehicle a/c systems will be sized different in total volume. Also, different brands of compressors can take different brands of oil.

<b>Per Bentley.....</b>

Audi &gt; B6 Platform &gt; 2002 - 2005
Air conditioning - refrigerant R134a Audi
87 - Refrigerant R134a/refrigerant oil capacities and approved refrigerant oils

- Various compressors have been installed depending on production period and engine (these compressors have no A/C clutch).
- At the start of production exclusive use was made of type "6 SEU 12" and "7 SEU 16" compressors from "Denso". With effect from Model Year 2004 a gradual change was made to different "Denso" compressors (types "6 SEU 14" and "7 SEU 17") Air conditioning and Parts List .

<b>Also per Bentley.....</b>

Audi &gt; B6 Platform &gt; 2002 - 2005
Air conditioning - refrigerant R134a Audi
87 - Refrigerant R134a/refrigerant oil capacities and approved refrigerant oils

- The replacement compressor contains the full quantity of oil intended for the refrigerant circuit. On replacement, the quantity of oil in the compressor is therefore to be adjusted Components, replacing.

- The Audi A4 is equipped with different compressors depending on the engine and production period As replacement compressors of this type are supplied with different oil capacities, the exact part no. must be noted Air conditioning and Parts List .

- At the start of production, the compressor types in the first line of the table were supplied with a refrigerant oil quantity of 180 cm 3. These compressors can be recognized from the index of the part number (8E0 260 805 with one index or with double index up to "AH"). In Model Year 2004 (as of approx. 01.04), a gradual change was made to other types of compressor with a refrigerant oil quantity of 120 cm 3 or 130 cm 3. These compressors can be recognized from the index of the part number 8E0 260 805 (with double index as of " AJ") or 4F0 260 805 (and index "E" for vehicles with 8-cyl. engine) Parts List .

- The reason for the different oil quantities in the compressor for an otherwise identical refrigerant circuit is the design of the actual compressor. Attention is to be paid to these oil quantities.. Too much oil in the circuit results in higher pressures and reduced system cooling output; insufficient oil can cause lubrication problems in the compressor.

- The compressor may have been installed at the factory with a rating plate indicating the part number and the quantity of refrigerant oil in the compressor.

you'll see different A/C Refrigerant Oil capacities given.

ETKA shows four different part numbers for the compressor in the B6 1.8T, and each may require different amounts of compressor oil. May be best to stick with the same part number that came off the car, regardless what ETKA says -- your assured that "the book" and your on car service sticker will match the R-134a and oil capacities that any tech will cross reference off your model year when servicing your A/C system in the future.

at the parts counter.

I guess the only way I know for sure it fits is to buy one that looks exactly the same.

Reason I ask is that it is recommended to replace other A/C components depending on the severity of the reason for replacing the compressor -- condenser, drier, orifice tube, etc. Any warranty you get with a new or refurb condenser could be void if some of these other components are not replaced.

If you had a massive leak in the system due to failed compressor or something else, the most important things are making sure the repaired system holds pressure, is purged/vacuumed of air and contaminates, and the correct amount of oil is added to the system and compressor. Most shops have an A/C machine that does/automates all this. I paid about $80 for the service, plus the cost of the refrigerant short in my system (the machine recycles whatever is still in your system).

DIY recharging systems are available, but I don't know enough about how they work to insure that the amount of oil being added is within spec for your compressor.

Here is the best read I found explaining the A/C system, related components and their purpose -- <a href="http://www.autoacsystems.com/_faqs/detail/compressor.html" target="_new">Replacing your auto A/C Compressor</a> .

Looks like the Bentley recommends replacing with new the o-rings (two total) on the two refrigerant lines going into the compressor.

Only thing I can think of is "A4III" might refer to the B7 chassis and it's 1.8T...

LMAO

I am currently bypassing the pulley until I find the unit I need.

From the looks of things the two units are not interchangeable.
