Hi, driving the inlaws r reg Avensis and heard a weird noise,the only way I can describe it is that a load of acorns were falling onto the roof ???????? weird!!!! eng management came on fleetingly...... the car was ok for a few days then the missus drove just round the corner and car just stopped. It turned out that the cambelt had somehow sheared lengthways and all the other belts had gone....... I guess one of the belts had snapped and had got snared in the timing belt area hence the weird no
