Tinware writing, Was this on all cars…?? Options

Hi All

Have seen this on an unrestored car…does anybody have anymore details…? I assume the 022 refers to the 1.7L but what about the other number?

Any insight would be appreciated…thanks

i had to reread up how VW parts numbers work again.
a mystery because it can never be fully explained unless you knew all the obscure parts groups and inconsistencies in numbers....... (IMG:style_emoticons/default/blink.gif)

but

first three letters in this case means engine group developed for.
would be the type 4 engine. (it can mean other things like model, but it will mean enigne in this case because its an engine part.)
022 = type 4 engine i think. (039 is the porsche designed 2.0 L variant)

second three letters mean the engine part.

133.
1 = engine.
33 = throttle body.

third three letters mean

location identifier.
067 = where it is on the engine (or could mean on the car itself).

letter at end means variation. A is usually the first. sometimes the first has no letter after it and then the first variation (ie second version) has the A. its inconsistent too. (IMG:style_emoticons/default/headbang.gif)

at some point VW changed its catalogueing order and throttle bodies were given a different location identifier of 062 in all their updated catalogues.
as a result of that 067 became 062 in PET and there would be some internal accounting that meant any replacement throttle bodies were reassigned the number. either with a new label on the box maybe or if parts were actually made in new batches maybe even stamped with a new number or whatever they did to cope with that to make sure you got the right part. (IMG:style_emoticons/default/headbang.gif)

so the H L R or S variants of the throttle body mentioned in the PET catalogue are new reassigned numbers and could appear differently on the original parts we have.
(IMG:style_emoticons/default/headbang.gif)

the PET catalogue is not much use except to say there are four variations. (IMG:style_emoticons/default/confused24.gif)

you have to find examples of the original parts in the 4 variations to work out what they were actually stamped.

so far we know there was an A version. (IMG:style_emoticons/default/sad.gif)
that could mean A version of original 1.7 throttle body = 1.8 throttle body.
all the other numbers are the same from 1.7 to 1.8. nothing else to distinguish except 1.7 TBs have no letter after the number as far as i can find.

i'm thinking it means A = what identifies a 1.8 throttle body from a 1.7 throttle body.

and that H could still mean the first sub variant beyond it being a 1.8.
but (IMG:style_emoticons/default/headbang.gif) & (IMG:style_emoticons/default/confused24.gif) is still really what i think.
given confusing possibilities of VW PNs its possible the first batch of throttle bodies (like yours might be StarBear) they just have the PN ending in A and there is no H because at that point maybe there was no other version yet superseding it? (IMG:style_emoticons/default/confused24.gif)
but after a second version has to appear - says its an L, they give the original version in its later batches a H as well. you just don't know with VW.

the only way to really do this is to collect images from people.
see what they have.
and try and get info from cars reasonably certain to be original.
