Hi all new member here, hope this is in the correct place. I was intending to buy an Audi A4 2.0T FSI Quattro S-line after looking for the perfect car for the last 4-5months. I've always been lead to believe that the 2.0 FSI turbo unit (as found in the Golf GTI) is very very reliable. However, after reading the article on page 19 of Audi Driver June 2007 (Issue 6 Volume 11) entitled Mysteries of the 2.0 TFSI I'm having second thoughts. The article discusses details of a 'common fault' around fueling which can cause the car to hesitate or for the ECU to put the car into limp mode. This is then cured by either running a test on the ECU and replacing the regulator or replascing the regulator and pump. I was wondering if anyone could answer the following questions for me: Is this really a common fault have people experienced this problem? Is it something that would be covered by the warrenty? Which year of models does it effect? Is there a proper cure, recall or mod as it sound like it could re-occure every 15,000miles? I would really appreciate peoples views on this, as I'm not keen to invest a lot of hard earned cash if a fault exists with this engine.
