If you want diagnostics cheap
Get a coding setup.
You need to know your way around computers to set this up buts its
not ultra difficult.
You can order a setup off ebay along with inpa ebidas ncsexpert dis57 and SSS for around
It allows you to code and do diags and is not vin number limited.
Its not as user friendly as the canned stuff.
You only need a Kcan cable for a 06.
The Bavarian technique cables are vin number limited so people are not likly to loan you
one as it uses up one of the three vin numbers you are allowed.
For the non shadow codes any reader will do even and elm327 for 20 bucks but you need
to translate the codes.
This may be of use also
There is also this
