I have noticed a massive difference between the Golf and Passat Tdi with regards to fuel consumption, the Golf eats it.......my TD5 Discovery is better and I thought that was heavy...
Not sure what it will do on a tank I top it up when it gets to just over half a tank, I will leave it this week and check..... funny thing is I only decided to keep this for a second car for myself and use it for a bit of fun at the weekends, I haven't been near the Discovery since I got this.......
