When you order the tool, the following "parts" will be delivered:
  • Strong box with LEDS and connectors.
  • Two cables, one for the connection between box and PC (com port) and one for the connection between box and the car.
  • Latest sofware version. Updates + security files after ordering are for free and will be provided to you via E-mail.
  • Optional: Notebooks today do not have a COM port. The DT928, DT911 and DT999 tool is also tested with an USB-to-COM converter. We have tried several USB-to-COM converters and not all converters work fine with the diag. It depends of the internal chipset of the converter. We found one converter which works fine with the tool and we can supply you the converter for an additional price.

    We offer a 1 year warranty. Our preferred payment method is bank transfer (or Paypal for our international clients).

    * note Porsche started to produce a car with "On Board Diagnostics" in late 1986. The diag feature became available as a standard feature in 1987. The 928s4 MY 1987/1988 has a rectangular 12 pin diagnostic connector located on the ecu mounting panel, while the 89 onwards models have a round 19 pin connector, located under the cover at the passenger seat. It is our goal to support diagnostics for both these systems provided that the ecu already has the diag feature. Contact us for further details
