If you have a crash and youve not told them that you have mods, and especially if the crash is your fault theyll send someone out to look at the car. If they find that it is not as you told them, they will void the policy. They may payout to the person you hit, but theyll probably take you to court to get that back (not sure about this last bit)
As for a service and warranty work, if theres a fault and its because of the mods, then Renault will not cover the problem.
Hope this helps.
