This answer is applicable for many BMWs in addition to the one listed below.
car year: 1995
car model: 525i
I just bought a 1995 BMW 525i, and the check engine light came on. Can you recommend a tool to read the code and instructions on where to read to plug in the tool.
We do offer a code reader tool that will read and clear the engine management fault codes that are stored when the CHECK ENGINE light comes on. The tool will also reset the oil change and inspection reminder lights (in the instrument cluster). The tool is used in the DLC (Data Link Connector) port, under the hood. See the photo below.
