Your camshaft or crankshaft (engine speed) sensor is faulty. 3. Battery voltage is lower than 12.5 volt. just a few reasons that I can think of. The only way you will truly know if 5k, 7500, or 10k miles between oil changes is acceptable for your specific vehicle and other variables, is to test your oil in stages - sending it out for analysis.

BrendanTT (03-25-2023) Q7 MK 1 Discussion - HELP::: Late Starting problem - Q7 3.0tdi BUG - Dear All, Frustrated and tired, i need help in diagnosing the exact problem with late starting (and sometimes never starting) of my 2007 Q7 3.0 TDI with BUG Engine. On different diagnostics and advices, I have already replaced the following; - Fuel The first 10 seconds there must NOT be any output. If it does output fuel, then your valve is likely to have a problem. After those 10 seconds you may see fuel output. 1) Leaking injectors. 2) Bad fuel pressure sensor. 3) Bad fuel pressure regulator (valve). 4) Not enough fuel coming from the filter. 1 1. A6 / S6 (C6 Platform) Discussion - fuel pump problem 3.0TDI - I have a 2005 A6 4F 3.0 TDI and in some strange way the car started to lose fuel to the injectors. I've noticed that the pump under the back seats is not working. Then I tested it with another pump and it didn't get any power. Hey everyone, I've done 4 test drives and have spent the last 3 weeks looking at an 2013 A6 3.0 that I really and I'm close to making the deal, however, I want to hear past experiences in terms of reliability and maintenance costs: The car is still under factory warranty for another 10 months or 4,000 miles.
