Just trying to find out whether my car has a belt or is chain driven,i've got the service book and at the front is all the info on the cars d.o.b etc and lots of codes but i'm not sure what engine code i have 795000 is currant miles,the service book says replace toothed belt at 114000 miles on all audi inc 2.0tfsi, would that apply to chain driven engines?,if belt driven would it best to get it done as the car is now 5 years old?, thanks in advance for any help/advice
