Hello all, having been an owner of a Toyota Corolla T-Sport for the last 3 years, changing to a new job means long distance commuting. I had to say goodbye to the CTS and now I'm an owner of an 53' reg Golf TDI PD with 71K miles I bought from a VW dealer. I made sure it had the timing belt changed before I picked it up last week. That's when my first encounter with trouble began. I thought the economy returned would be around the 55mpg region having seen some posts in the forum. Unfortunately, I'm getting 45mpg and if I drive like a granny, just hit 50mpg.... I've searched the posts and it appears that the MAF maybe the culprit. And so, I rang the dealer and got it booked in for a check and diagnostic next week. When I mentioned that the MAF could be faulty, it was dismissed without any hesitation by the service chap!!! He just said that there's VW has no such problems!!?? Now I'm really confused and was considering getting a MAF replacement and also having it re-mapped/chipped by chipped UK. Do you think these would help improve the fuel economy?? Thanks in advance!!
