These fantastic luxurious, quality cars and vans are very widely sold and have a huge loyal fan base mainly due to their track record of quality, safety, robustness and value for money. Mercedes have been building thousands of engines for many years now, so It is not surprising therefore, that they have been fitted with many several different sump plugs.

Is there an easy way to tell which sump plug is the correct one to be fitted to your car?

Fortunately, there is. Rather than looking at loads of lengthy tables with engine numbers etc, and then still getting the wrong one, because the table was not 100% right, you can just follow the these simple steps:

  1. Firstly, have a look underneath the car at the sump, then locate the sump plug and see what it looks like.
  2. Does it have a round smooth outside, 19mm diameter with a 13 mm Hex head on it?

    Then it is an SP7:

  3. Does it have a round smooth outside, 17mm diameter with a 13 mm Hex head on it?

    Then it is an SP23

  4. Finally, once you know which Sump Plug is the right one for your vehicle, don't forget to order it from our online store.
