Part numbers across VAG range..?

[sveed1.8T]

A lot of VAG cars over the years share some of the same parts.

Now the part number generally remains the same, but different models tend to have a different letter at the end.

Does this mean that the part would be interchangeable IF the part number was the same?

I hope people understand what the hell I'm trying to say


For example:

038130073BA

038130073AJ

^^The number is the same, but do the letters mean that they cannot be interchangeable?

I might be wrong, but I thought that the number referred to a version of the part.

E.g. there are different versions of the N75 valve, the version ending in 'J' was originally for an Audi, however will still fit a MK4. Although it fits, it might not always be the best part to use.

No, it doesnt always work like that....although the last letter is different and same numbers are in the part number, the part might refer to something completely different.

Superceed'ed parts are fine as they designed around the original part.

Meh, back to the drawing board then

Vag parts are labelled as follows. (As far as I can remember, so don't take it as gospel)

First three numbers denote what the part relates to engine, transmission, platform etc.
038 is an engine code that wiki tells me is a 4pot diesel.

Next is the system and sub system.
1 is engine
I assume 30 must be injector.

Next three are the part number. So 073 will be an injector design. Anything with this number should physically fit.

The suffix usually denotes a part revision, but in this case it will be variant. So a different flow rate for example.

Nah,  wouldn't say that's the case.  A lot of part numbers for 1.8T start with 038 such as gaskets etc,  so saying 038 relates to a 4 pot diesel is wrong. Example:

Interesting info in this link:

Back to the OP, according to that the letter at the end shows part version or revision.

If you're still unsure have a look at 'Set 4' this link:

http://www.myturbodiesel.com/1000q/VW-Audi-part-numbers-system-explained.htm

Set4 p
This is a version or revision code.  In this example it's "p".  If it's included it's usually one or two letters.  Sometimes a revised part comes out or it's slightly different on models with different engines.  A newer version doesn't mean the old version isn't the newest one that will work on your car.  They will use a, b, c., etc., but also skip letters.  Sometimes they name them aa, ab, ac, etc.  Usually the newer part has a later letter.  If it's "x" it means the part is rebuilt.

Those will be common/carryover parts, that would have been designed for something before the 1.8T. I just googled 038 engine code and it came back with the diesel engine (as it's a diesel injector I thought it's a safe bet that that's the part origin).

If you look at those 036 prefix parts in your picture, they are stuff that you wouldn't want to design specifically or renumber. A stem seal and a split retainer. The components designed for that family of petrol engines have 058 06A and 06B as a prefix.

If you look at gaskets, as you gave in your example. Gaskets for common things, like the throttle body/intake plenum have been used elsewhere. (the throttle body is an 028 prefix). Whereas something engine specific like the intake manifold gasket has an 058 prefix.


Like I said it's not gospel and I might be wrong, but it is logical and similar to many other part numbering systems I've come across before. Can you do a search on that stem seal and see where else it was used?

Used in near enough everything.

This is how I see it.   (lets use a mk4 ball joint as example)

1J0, 1K0, 1ML is your chassis code.  1J0 - golf 4 , 1K0 - Golf 5, 1ML - Leon I think.

Next part is your Main group:

1 - Engine
2 - Fuel/Exhaust/Cooling
3 - Gearbox
4 - Front Axle/Steering
5 - Rear axle
6 - Wheels/brakes
7 - Pedals
8 - Body
9 - Electrics
0 - Accessories/infotainment

So now you have 1J0 4


next off is the Sub group......2 numbers which refer to a group of parts in the parts manual. 

This has a sub-group of 07

So now your up to 1J0 407

next 3 numbers are just random numbers assigned to that part In our case, they are 365 (you will note that a odd number on the end of these set of numbers tells you which side they go on the car......Odd = passenger side)

So we up to 1J0 407 365

next part is the revision.  If there have been multiple revisions of a part (N75 for example) VW will superceed the old one with a newer part number.....so that letter on the end then becomes C to a E or  E to F or whatever is chosen by VW.

In some cases, such as interior trims, you will see a color code number on the end.  B41 is satin black color trim and you will find different codes for different colors.


Hope that helps a bit more.

Yep sounds logical
