The new camshaft drive belt, PN 944 105 323 00 from Pirelli, can have visible seams in the web/tooth base area.
These seams are a result of the manufacturing process, and must not be mistaken for damage type "cracks at base of teeth" as shown on page 4, example 1, of Technical Bulletin Group 1, Number 8715, Book D, page 60. These production seams have no effect on the service life of the belt.
Always replace the former version camshaft drive belt (Uniroyal, PN 944 105 157 06), with the new type Pirelli belt.
