Thats a nice looking vectra you have there mate, iam driving my boyfriends vectra at the mo as my golf has broken down & stuck on my drive

But anyway back to your question, MAF's (mass air flow sensor) is a common problem with all mk4 golf's, it'll make the car feels very sluggish, very easy to replace tho, n cost about £75... not to sure on any other common problems on the tdi models but iam sure someone here will know.
