Manufacturer-specific points

We are currently aware of the following points regarding EOBD / OBD-II fault diagnosis:

Audi

Certain models of the Audi A4 and A6 do not appear to have sufficient clearance around the EOBD / OBD-II connector to allow connection of most tools. This appears to be a manufacturing design fault on these cars.

Ford

A large number of European Ford cars have been found to support EOBD / OBD-II diagnostics back to approximately 1997. Most petrol Ford cars with the EEC-V engine management system are EOBD / OBD-II compliant.

Jaguar

A large number of European Jaguar cars have been found to support EOBD / OBD-II diagnostics back to approximately 1998, however they do not generally work well with EOBD / OBD-II handheld code readers.
We recommend PC-based or Jaguar-specific tools for reliable trouble-free diagnostics.

Peugeot / Citroen / Renault / Vauxhall

Whilst a 16-pin connector was present on some Peugeot / Citroen / Renault / Vauxhall cars before January 2001, it appears that they did not support EOBD / OBD-II diagnostics until January 2001. The wiring of the earlier connector, or the software protocols in use do not appear to be EOBD / OBD-II compliant.

Rover and MG

A large number of Rover and MG cars do not seem to have the Signal Ground pin (pin 5) connected on the diagnostic socket. Diagnostic tools that rely on pin 5 as a circuit ground do not power-up correctly on these cars.
All the tools we currently stock have pins 4 & 5 deliberately shorted together to combat this issue.

Volkswagen

Certain models of the VW Passat do not appear to have sufficient clearance around the EOBD / OBD-II connector to allow connection of most tools. This appears to be a manufacturing design fault on these cars.
