Hopefuly someone can suggest something for this:
I bought my car (B5 2.5tdi), last year, and it used to sit at bang on 90c but now, 30,000 miles later, it won't really go above 75c (even in summer). I was wondering if this is a blockage.
Also, this is probably just me imagining this, but my mpg has also gone down over this time from 540miles per tank to 480miles per tank. Can this be linked? I have had the car serviced by a reputable audi specialist at the correct milage (currently done 104,000 miles). Am I being paranoid, or is this usual for this age of vehicle?
Thanks for your help in advance
