I heard that some older 21303 WALL-E models (LEGO Ideas #012) have a weak neck connection and that LEGO fixed that in later production runs, and that if I have an older WALLE I can contact customer support to have a "neck kit" sent over.

How can I tell if my model is the older or the newer version? There's nothing obvious on the box, and there is no information on the official LEGO website.

I contacted LEGO and this was their reply (emphasis mine):

All LEGO® 21303 WALL-E sets produced during or after November 2015 already include the neck stability revision, which includes revised Building Instructions and extra parts. You can tell the production date by checking the manufacturing code which is usually printed in black ink on the clear tape holding the box together. If your number is 47(S)5 or higher, your have the revised set. You can also tell my looking at the Building Instruction number. This number is printed at the bottom corner on the back cover. New revised BIs produced from November onwards will have the number 6162870 or 6162871.

Unfortunately my BI number is 6146260, so I guess I have a model with the old neck connection.

  • My number on clear tape of the box is 38 R6 but instructions have number 6162871, which indicate the revised set. The neck part is a "ball" and not the clicking mechanism as shown in some youtube videos for the problematic version. Commented Dec 28, 2018 at 16:26
