Customer Questions & Answers

Which BMW models and years is the 20-pin OBDI to 16-pin OBDII converter compatible with?

The converter is designed for BMW vehicles that use the round 20-pin OBDI diagnostic connector, commonly found on models built from the early 1990s up to around 2001, before the standard 16-pin OBDII connector was adopted. We recommend checking the physical connector on your vehicle before purchasing.

What materials and dimensions does the adapter have, and how much does it weigh?

The adapter is made from high-strength ABS polymer and internal copper contacts. It measures approximately 28 cm in length (including connectors) and the 20-pin connector has a diameter of 6 cm. Approximate weight is 120 g.

Does this converter allow you to use all OBDII diagnostic functions on older BMW vehicles?

The converter only adapts the connector physically, allowing OBDII tools to connect to the BMW system. However, full functionality is limited by the vehicle’s electronics: some BMWs made before 2001 do not support all OBDII protocols, so data access may be partial depending on the year and model.

How should the adapter be installed, and is any additional setup required?

Installation is simple: connect the 20-pin end to the round diagnostic port under the bonnet and the 16-pin end to your OBDII scanner. No software or additional configuration is required. Make sure the ignition is off when connecting to avoid short circuits.

What technical differences are there between this converter and similar universal adapters from other brands?

The main differences between adapters from different brands are usually material quality (ABS versus generic plastics), pin alignment accuracy and connector robustness. Technically, they perform the same function, but lower-quality versions can cause intermittent contact or have a shorter service life. There are no functional differences if they comply with the BMW-to-OBDII pinout standard.

What is the BMW 20 pin to 16 pin OBDII adapter for?

It is used to connect older BMW vehicles with a 20-pin OBDI connector to modern diagnostic tools that use the 16-pin OBDII standard.

Is it compatible with all BMW models?

It is compatible with BMW vehicles fitted with a 20-pin OBDI connector. Compatibility with other models or brands is not guaranteed.

Does it need any additional setup to use it?

No, the adapter is plug and play, so it does not require any additional setup for use.

Can I use this adapter for workshop diagnostics?

Yes, it is ideal for workshops and mechanics working on older BMW vehicles that use the 20-pin OBDI connector.
