Dont like that la.. give ppl a chance ma..

To get to the service centre, you cannot go via OUG. There is no link (last i know). You'll need to go into Jalan Puchong from Old Klang Road (Jalan Klang Lama). There will have a signboard stating turn left into OUG industrial park. This is as far as I know.

Although it say OUG, but I have no idea why the road into is from Puchong instead.
