OK, this is not earth shattering but......
A bulb blew on one of the headlights on our
Renault Scenic. No big deal. I bought a new bulb and headed home.... I looked under the bonnet (hood) and could see no way of accessing the headlights. I checked in the owner's manual only to find that Renault "recommend that the bulbs be changed at the dealer". Bastards. So apart from the massive inconvenience of it I will have to pay about €75 every time a bulb blows. Fantastic. I Googled and found that I am not alone - many other freaks like me have ranted about it too. It's a total scam designed to make money for the dealers....
28/11/05 Update - OK, in fairness the dealer in Sandyford only charged €10 to make the change and did it in about 5 minutes.....
