It's often asserted on this and other forums that the letter(s) at the end of a (9 character) part number is 'just a revision level'.

People claim and assume that an alphabetically later letter or pair of letters is the same part but new and improved, or from a different manufacturer, or whatever. They assume it'll fit and work

 

But it simply isn't true, not all the time by any means.

 

Example, brake discs with core part number 6R0 615 301

 

Without any letter at the end, that's a 256mm disc fitted to various Skoda models, as well as other VW-group cars. 

It's obsolete now, dropped on Feb 1st 2017, replaced by the part number 6R0 615 301C

 

Not 6R0 615 301A which is a 288mm disc, nor 6R0 615 301B which is a 310mm disc. Neither of these is likely to fit or work...

 

Another common error is to mistake the third character in a part number as a letter O when it is really a numeral zero. Hampers search engine research when this is mis-entered.

 

 

 

 

 

Thanks, I did not realise that.

 

Can you expand the topic by explaining how trim colours, finishes etc are differentiated in the part numbers? Assuming you know.

 

I find it almost impossible to discriminate between a O and a 0 on a text/numeric string on a computer screen, side by side as I have typed the difference is clear enough but not amongst other numbers and letters, in fact its only when they are mixed the problem occurs.

 

G00gle does seem quite good at coping with my handicap!

Not something I can help with, sorry.

Others are more than welcome to chime in though, if they have useful knowledge of such things.

 

There are lots of things in ETKA that remain mysterious to me, I'll probably add some later as I think of them, in the hope someone can demystify.  🙂

I recall when ordering front grille, bumper and interior trim plastic parts from TPS that there were suffixes for the colours but not the details or whether it was used consistently.

A handy site to see which part numbers actually are equivalent is skoda-parts.com

 

Type in a known correct part number for what you want, and it tends to take you to the page selling the latest version, but very helpfully all equivalent part numbers get listed in a grey font just under the main item title.

e.g.

https://www.skoda-parts.com/spare-part/6r0615301c-front-disc-brake-256x22mm-ferodo-4177.html

So yes, what @Breezy_Pete has said about O (as in Oscar) and 0 (as in the number zero), there are no parts I have ever seen that use the letter O.

AFAIK there is also no part that has I (for India) and there is only 1 (as in the number one) used in the parts catalog.

 

 

Regards to the question about colour codes, here you can see a basic idea of the choices

Here are some parts snippets, and you can buy some things without any colour preparation
