HI! Since I couldn’t really be helped on the Seat-forum, I just ask the VW comrades here! So I own a 1.4TDi and I’m quite happy with the small one and have a few questions. 1. What does this mean in average of the timing belt changes? Was already at some workshops and are so 350€ a real number? And what do you think of having the water pump changed with you? 2. Since I now have to make another oil change, what kind of oil do you recommend to me? Have you got some tips? 3. Can I drive biodiesel with my little one? Unfortunately, I don’t have a manual for the car anymore, therefore the question. 4. What do you think about installing an open air filter kit ( K&N, Raid etc.)? Or is a change mat ala K&N sufficient? I would like to thank you in advance for the answer! peace
