I need your help to buy a car tester such as Bosch KTS http://www.bosch.com.au/content/language1/html/5111.htm or other that gives good results.

I can't be specific what operations I will do, but mostly ECU error codes removals and some other faulty code diagnosis identification.

So, are there any car service owners around that can point me in the right direction ? I live in Europe btw, so the tester must cover the major european car brands.

Thanks
