Adapter looks, feels and works very good. App is exactly opposite. it connects without problem to the car but it doesn't bring much functionality. at least without extra "smart mechanic" subscription. I feel they could give me little bit more Info about Erorrrs but they don't. they make my life difficult because I don't want to pay more. I can't justify the prise i already paid. + Instead of E85 i get E89 Picture.. not deletable Errors can't be hided. so my car has always status. Very bad...

Thanks for your feedback. Carly does support the Z4 E85 (2002–2008), and we show all fault codes—critical and non-critical—to give you full visibility. Some don’t require fixing, just monitoring. Would you like me to check more details? I’d be happy to help. Please let me know if anything we can do you turn this into a more positive experience!

Doesn't work AT ALL which I initially thought would depend on the phone I was using. Tried two other phones since then, no change. On top of that it's a subscription with no communication of a pending renewal and to cancel you still need to have your last invoice -- if you can find the cancellation form at all. Sure, you are within the legal limits but would this be necessary if you had a real good product that's worth the price?

Thank you for your feedback! This could be a scanner or app issue, and we need to investigate. The auto-renewal is clearly explained at purchase, and customers can cancel anytime before renewal. If you're experiencing issues, please leave your ticket number, and we’ll be happy to check your case!

The application bundled with the adapter aggressively advertises itself as a solution for coding and detecting faulty codes on all brands, including Mercedes. In practice, Carly is a completely useless product and I fell for false advertising. It was my mistake not to research further before impulsively purchasing the product. If I could leave a zero-star rating, it would be generous. I also own a Volkswagen, and Carly is overrated; most free tools are more useful. Please don't bother responding
