After much back and forth I have yet decided to buy me at the end of the unit. Surprising I was when I on a 95er Golf 3 (already the 16 pol.OBD II socket) ... have been stuck, Setting the language and going. it works. Error found and eliminated. then I did the same still plugged into my 2008er Golf V. No error is detected. It also works. Conclusion: price / performance is very good, (eg ABS sensor switch.) Will only take in case of error paid. A star deduction there because every time neim plugging the language must be set and because only a few control units can be read
