Has anyone used, had success with the replacement Door Latch / Lock modules from Ebay / China? Normally, I would not even think of this, but with all of the revisions, numerous failures of the factory ones, I am questioning if they can be any worse...
I have learned waaay more about these than I care to in recent weeks, but interestingly enough and depending on year ( these are shared with a TON of cars ), ranging from the Huracan, Porsches, Toureg, other VW's etc... They are all made in Italy.
My wife's 2010 TT is a split year for these modules, and I ordered replacements from Porsche because they were actually MUCH cheaper than anywhere (only to find that our build date is exactly on the split and I screwed up with the "Up to" OR "Greater than >>" build month... So, I bought ones for a later TT (Late Build 2010 and up).
Essentially, the Differences (other than Right/Left) is the # of pins on the Connector.
Ours are "B" and apparently that PR-4I2 from ETKA is supposedly on the option sticker in the boot (with I have not confirmed personally)
8J1 837 015 B (PR-4I2) - 9 pin D Shaped Connector
8J1 837 016 B (PR-4I2) - 7 pin D Shaped Connector
D - MJ 2010>> - 02.11.2009
Where as "D" versions are:
D - 02.11.2009>>
The ones I ordered from Porsche were:
8J1837015D -->Revised to --> 8J1 837 015 F (Porsche# on box is 9A783721506 but printed PN on part is 8J1 837 015 F) - 7 Pin D Shaped Connector
8J1837015D -->Revised to --> 8J1 837 016 F (Porsche# on box is 9A783721606 but printed PN on part is 8J1 837 016 F) - 6 pin Oval Shaped Connector
...There are also "A" and "C" versions (again depending on split year build date) and Options Data Code of: PR-4K4
