This post is WorkInProgress and not complete. The dates refer to production dates.
Several members have contributed to this information overview on another post https://www.a2oc.net/community/inde...view-for-neophytes-newbies.39907/#post-427861 and below.
If you have additions to this post, pls add your input, and I will update the main overview accordingly.

Diesel - Engine Codes
AMF
(75bhp Euro3) Launch until August 2003
BHC (75bhp Euro4) September 2003 to end of production.
ATL (90bhp, Euro4) from Sept/Oct 2003, withdrawn late 2005/2005
ANY 1.2TDI from June 2001 to end of production (not sold in UK). The Lupo 1.2TDI changed from ANY to AYZ in 2001. Only difference between the two is that the former's EGR is vacuum actuated while the latter is electric.

Diesel - Gearbox Codes
FLE
- 1.2TDI (ANY) automated manual used in 3L A2 & VW Lupo.

02J family (MQ250 - manual, 250Nm limit)
EWQ/EEA - 1.4TDI (AMF)
GPK - 1.4TDI (BHC)
GRJ - 1.4TDI (ATL)

Petrol - Engine Codes (all Euro4):
AUA 1.4 Launch until some time in 2002
BBY 1.4 from May 2002 until end of production.
BAD 1.6 FSI from May 2002, withdrawn late 2004/2005

Petrol - Gearbox Codes
02T family
EYX - 1.4 (I think there are a few more but same ratios etc.). 02T family, lower ratios.
GSK - 1.6FSI - again there may be a few more codes for these. 02T family, longer ratios.

Other related gearboxes
MZN - Polo Bluemotion 5-speed gearbox for 1.4Tdi with longer ratios. 02J family or very similar.
MYP / PTW / NRG / PTU - Golf / Passat Bluemotion 6-speed boxes, long ratios - closely related to 02J boxes & can be retrofitted with minor modifications. Few other related codes from similar VAG vehicles.
DSK gearbox was used on the Lupo 1.2TDI/3L until 2001. Same ratios as FLE, is interchangeable but has slightly different internals. DSK may have been used on early A2s.

See HERE for more details on each of these, however the key info when choosing which to look for is that the PTW has the appreciably longer gearing in the lower gears similar to the GRJ 5 speed (TDI 90 / ATL engined cars), when compared with the other six speed options and hence could be argued is more suited to upgrading a TDI90 / ATL: The others are indistinguishable from each other in terms of the conversion and their lower gears match the gearing of the EWQ / EEA / GPK - This is worth bearing in mind if you are simply looking to "add a gear" on to what you have now.

@Proghound / @Special edition could this be made a sticky?

My addition, perhaps it could be incorporated into the above and then this message deleted:

There are bound to be slight variations in the dates for the different regions. Probably safe to say Germany received before UK, likewise for regions with specific needs for cold climate etc may have had theirs earlier or later.

No, because all A2s were produced in NSU. All the German wiki dates are production dates.

BHC brought Euro 4 capability with. There was a clear cutover there, with it coming in after the summer break in 2003. Not quite sure why it was done then and not the year afterwards, as E4 was only relevant after 1.1.2005; having said that, there were the D3 and D4 norms and their effect on yearly tax (which was not insignificant). This is also why you'll see D4 on the 1.2 documents, it's an emissions class.

AUA vs BBY is relatively simple but registration is no clear guide, it has to be production date. There's no difference in emissions, just this list of changes here: https://wiki.a2-freun.de/wiki/index.php/Unterschiede_AUA_BBY

The info on the German wiki is extremely likely to be substantiated both by production information and by VAG internal documents without them actually being quoted.

^^ I would like to clarify this: at one point there were multiple Audi employees and mechanics very much busy on the German forum. There are many threads which have had to be deleted because users realised they have said "too much"; corroboration for many data points on the forum is therefore hard to get in public but the majority of information really is good. Especially the wiki - it's easy to edit that through and not all forum users have edit rights anyway, just a small selection.

The ANY of the A2 was used until the end of production. The Lupo 3L changed from ANY to AYZ in 2001. Only difference between the two is that the former's EGR is vacuum actuated while the latter is electric.

DSK gearbox was used on the Lupo 3L until 2001. Same ratios as FLE, is interchangeable but has slightly different internals. DSK may have been used on early A2s.

Is there a tread or a list somewhere of places that offer the service of upgrading / switching the gearbox. I have it on my list for this year, but I don't know where to start to be honest. I wouldn't even know whether I would need to source the gearbox myself or not. I'm sorry, but I'm a total noob at this...

DS Motorsport in Coventry did mine and I’m happy with their work - PM me if interested.

A related question:
I have an old Lupo 3L with the ANY 1.2 TDI engine that is in good condition, but the body is rusting away. Just bought an A2 with the ATL engine and considering to make it even less hungry by swapping the ANY engine to it. Both engines have variable vane turbos, and also other components look similar, EGR and tandem pump, etc. (unlike in AMF), so maybe the old ATL ECU would control the ANY as well, with different mapping, though. I would keep the manual GRJ gearbox, therefore the critical question is, if the ANY block could mate the existing gearbox at A2? The ATL comes with a double mass damping system in the flywheel, so that may be the biggest obstacle, if it does not mate with the ANY driveshaft? From pictures I see that the ANY block is much smaller, but the bolt attachment setup looks quite similar.

Haven't we already been here a few weeks ago, with the conversation starting from this post? You're asking the same people the same question. If you get answers, I wouldn't be surprised if they're the same ones you got before. With most of the membership on this forum being UK-based and the very small number of 1.2TDI in the UK, I doubt if anyone who hasn't already posted up has the definitive answer.

Sorry, I did not see Valpen in the previous chain, and He/She seemed to have in depth knowledge on the different gearboxes. I also checked the German forum, and found some additional info, but does anybody have any specific German contact to mention? The ANY block has been very popular in various hobbyist projects, so if that is doable, somebody certainly has done it. I remember somebody even used it in a motorcycle, and another guy even cut the third cylinder away to make a super frugal two-cylinder.
