Set for MK1 MK2 Golf Gearbox Inspection Plug/Cap 020301129D 02

Three decades is a long time for a plastic plug to sit in a gearbox housing, cycling between cold mornings and hot oil. On a Mk1 or Mk2 Golf it is the sort of part nobody carries until there is already oil on the driveway. This is a replacement set for the gearbox inspection plug and cap.

One number does the checking

The number to work from is 020301129D, which the supplier gives in the listing. Read it as a cross-reference for matching, not an origin claim: it tells you which part this item is meant to interchange with and says nothing about who manufactured it. The title also carries a trailing "02" with no explanation attached. That may be the start of a second reference or a truncated code, so if you are matching against a catalogue, go from 020301129D and check everything else against the photos.

What the supplier does and does not tell you

The source description is thin, and it is better to say so than to fill the gap with guesswork. The listed size is 11.5 x 4.5 cm with a stated tolerance of 5-10 mm, and the colour is given as black and green, which reads as more than one item and matches the pack being sold as a set. How many pieces are in that set is not stated anywhere, and neither is the thread size or the sealing arrangement. On a gearbox part those are the details that decide whether it holds oil, so measure what you are taking off first.

Key features

• Cross-reference 020301129D: the number to hold against the part you are removing.
• Sold as a set: the supplier lists black and green components together in one pack.
• Plastic construction: a like-for-like replacement for the original moulded part.
• Mk1 and Mk2 Golf: the only models the supplier lists it against.

Check your part number

• Match 020301129D against the number on the part you are replacing. The trailing "02" in the title is unexplained and should not be relied on.
• No year range is given for Mk1 or Mk2. Confirm against your own gearbox code before ordering.
• Piece count, thread size and seal type are not published. Measure your existing plug and compare it against the photos.
• Check the gearbox oil level and confirm the plug is sealing after fitting. If you are not set up for that, have a qualified person do the work.

Ordered against your own number it is a short job, and a good deal cheaper than chasing the leak later.
