bought one a few years ago, crap!! unless u can understand the data you are reading forget it ,and the can only do engine management so next week when your airbag light comes on its useless and the fact that you have a hdi engine more than likely it will show up freeze frame data.relating to fuel pressure problems which can range from injectors to pumps,your only guessing and theseparts are not cheap,your only gona pay more in the end.even with pro diagnostics they can only guide you you still have to be experienced to understand the data.
