Hard To Find – Dash Light Rheostat

There can be times when you have a part you need to replace in your car, but can’t seem to find it anywhere. This leaves people wondering why their car is left without a part that’s important to the operation and day to day use of the vehicle. Something like a dash light rheostat can definitely be hard to track down or purchase, especially if you are looking for a Mercedes Benz dash light rheostat, Saab, Jeep or otherwise.

Why can’t I find a dash light rheostat to buy?


 

Manufacturers like Mercedes Benz do not actually manufacture many of the components in their car. They purchase them from an outside source or third party company, these are known as OES or Original Equipment Supplier. These are essentially the same part you would have received from the factory, just without the OEM logo. These companies are independent of your parent car manufacturer, and can supercede the part, change it or even discontinue it all together.

As always, when purchasing a part that’s not from your original manufacturer, you want to make sure that these parts are indeed from a certified OES. If the part is not from a certified OES, then you run the risk of your Mercedes Benz rheostat being an aftermarket unit.

Are Aftermarket Mercedes Benz dash light rheostat manufacturers any good?


 

This will depend on who you purchase from because there will be plenty of aftermarket manufacturers that will make dash light rheostats with much lower pricing and lower quality materials to match. In some cases and likely many for examples like this one, you will have no choice but to purchase an aftermarket unit.

VDO is the OES supplier for Mercedes Benz part number W0133-1622007 and it fits the following models :

  • 300SDL | All Engines | All Submodels
  • 420SEL | All Engines | All Submodels
  • 560SEC | All Engines | All Submodels
  • 560SEL | All Engines | All Submodels

It may be possible to contact VDO directly regarding a replacement rheostat, but it won’t be a plug and play affair. At that rate a universal potentiometer from the local hardware store will do the same job with the same three contacts.
