my leon fr tdi 170 is on an 06 plate and in july is 4 years old and due its 4th annual service but only done 31,000 miles is it worth leaving the cam belt change untill the car is 5 years old and maybe on around 40-45,000 miles ? or do you recommend that 4 years is bang on and would be too risky to leave ? also does anyone know what the usual price for a belt change is @ a seat dealers ?
