febi bilstein 38023 Automatic Transmission Oil Dipstick, Red Plastic
Product description
Checking the automatic transmission oil level during vehicle maintenance is the job this dipstick is intended for. It is a red plastic replacement part from febi bilstein, listed for selected Mercedes-Benz models. The key decision is fitment: matching the vehicle matters more than choosing by appearance alone. It suits a specific maintenance task, rather than being a general-purpose measuring tool.
Key features
The febi bilstein 38023 is designed to help check automatic transmission oil level. Its red plastic construction and stated overall length of 1215 mm identify the part, while the listed measurement accuracy is ±4 mm. Those details may help when comparing it with a required part, but they do not establish that it fits every vehicle in a model range.

The supplied fitment information names Mercedes-Benz C models 202, 203 and 204, E models 210, 211 and 212, SLK 170, Sprinter 906, and Vito and Viano 639. An OE number, 140 589 15 21, is also given for comparison. Treat these as checks against the vehicle’s exact identification and existing part, rather than assuming that a similar model name is enough.
Fit and sizing


Vehicle compatibility is the main sizing question here. The listing names several Mercedes-Benz model codes, but the vehicle details should be checked against the product’s compatibility information before purchase. A solid pick if your vehicle is confirmed as compatible and you need a dipstick specifically for automatic transmission oil level control. If you are matching a replacement, comparing the OE number and the part already fitted can help narrow down the correct choice, neither should replace checking the full vehicle fitment.

Tips for day-to-day use
This part is intended for vehicle maintenance, so it makes sense when a transmission oil level check is part of the work being carried out. For example, a technician maintaining a compatible Mercedes-Benz can use it for that level-control task rather than relying on an unrelated measuring tool. Follow the vehicle manufacturer’s information for the check and any repair work, the product details do not provide a vehicle-specific procedure.
Installation is stated to be for trained specialists, and products are usually supplied without installation instructions. That makes it a less suitable purchase for someone expecting a guided, do-it-yourself fitting process. If you prioritise a part matched to the vehicle for a workshop maintenance job, the intended use is clear, for a different transmission or an unconfirmed model, this listing does not establish suitability.

What to clarify


Which vehicles are listed? The fitment details name C 202, 203 and 204, E 210, 211 and 212, SLK 170, Sprinter 906, and Vito or Viano 639. Confirm your particular vehicle against the full compatibility information, as model family alone may not identify the right part.
What is the OE number? 140 589 15 21 is supplied for comparison purposes. Use it as a cross-check, not as a substitute for confirming vehicle compatibility.

Can it be fitted at home? The product information says installation should be carried out by trained specialists and that instructions are usually not included. It does not provide a fitting procedure.
Buying verdict
The febi bilstein 38023 is worth considering when you need an automatic transmission oil dipstick and the vehicle fitment is confirmed. Its stated purpose, material, length and comparison number give useful identification points, but the compatibility check is decisive. Not the best choice if you cannot establish that it matches your vehicle, or if you need a part with supplied installation guidance for a home repair.
