Ordered before 2pm on a working day, these are dispatched the same day by express courier and normally arrive within 1–2 working days.

Parts supplied from our European supplier

A large part of our range is held by our supplier in Germany rather than on our own shelves. We order these in for you as soon as you place the order. They normally dispatch within 7–10 working days, and are then sent on by express courier like anything else. Nothing ships to you direct from Germany — it comes to our Arlesey workshop first, so you deal only with us for returns and warranty.

Collection from Arlesey

Click and collect is available on parts we physically hold. If an item has to come in from our supplier it cannot be collected, and checkout will tell you so before you pay.

International

3–5 working days once dispatched. Any customs charges or excise duties are the responsibility of the buyer.

Frequently Asked Questions

What is a detent core plug used for?

Detent core plugs seal the detent ball and spring bores in a manual gearbox casing. They prevent oil from escaping through the bore hole and maintain oil pressure in the selector mechanism.

When should these be replaced?

These plugs should be replaced whenever the detent assembly is accessed — for example during selector repair, seal replacement, or a full gearbox rebuild. Reusing old plugs risks leaks.

Is 23311224825 the same as 23127527439?

Both part numbers refer to interchangeable plugs for the same application. The different numbers reflect manufacturer supersession or cross-referencing between BMW and other applications.

How many plugs are included?

This listing is for a single plug. Please add the correct quantity to your cart for your gearbox rebuild.
