Will this clear an SRS light on a 99 C70 coupe due to dash work? Can this also bleed the brake system on the same vehicle? Thank you!

This unit will be able to clear your SRS light, it will not be able to bleed your brakes. We recommend the Motiv power bleeder for bleeding brakes on all European vehicles. https://www.fcpeuro.com/products/brake-bleeder-essentials-kit-mot0100kt

Recently purchased and returned MD808 PRO to another supplier due to incompatibility with my car. FCP Euro states this device is compatible. Please confirm that your MD808 will fully support all modules and diagnostics advertised. Primary car is a 2018 Volvo V90CC (VIN YV4A22NLXJ1027003). Last tool purchased would not even recognize VIN.

You may have better luck with the MX808 on such a new/advanced vehicle. Check out this link for complete functionality. https://pro.auteltech.com/measurecar-1-1.html?m=4
