Q7 3.0 TDI - turbo actuator fault J724 - P3348-004 P3348-004. Thread starter andyha2000; Start date Apr 5, 2019 the local Audi dealer supplied it and said I am working on a 2015 Audi Q5 that has the 2.0 engine and will be replacing the starter. **The steps in this video apply to the 2.0 gas engine and may not w Oct 12, 2018. #3. You have to remove the front bumper and put the front end in the service position. Then you need a breaker bar and a large torx bit to be able to slacken off the tensioner. After this you can remove the belt and replace and tensioner if you wish, it is only 2 more bolts. Tbh it is highly unlikely it is the belt causing your Q7 MK 1 Discussion - any one got repair service manual for q7? - any one got repair service for repair manual for Q7 i really will apreciate it got a problem with epc light and check engine light red light stalls and when driving the both light turn on fro an instant and car losses power both cases rev go down Keithuk said: Diesel Particle Filter Emergency Regeneration. MVB 070.1: Regeneration Status (xxxxxxx1 = Normal Regeneration active, xxxxxx1x = Forced Regeneration active) Uhm, the page you referenced is for "1.4l/1.9l/2.0l R4 & 2.5l R5 PD /PPD-TDI". I'm reasonably confident that the OP 's Q7 does not have one of those engines. Dear Christopher ! Your topic is very interesting, I also have a 2010 Q7 3.0 Tdi and a motor problem indicator. After diagnosis with VDCS, there appears a P229E defect: Sensor Nox 2 rank 1, electrical defect. Jul 2, 2015. #9. That's not just a little oil, that is crazy. I'd do a flush and fill and see what happens. Its possible the heater core is plugged. Check the hoses going into it, they both should be close to the same temp, with the inlet being very hot. If the inlet is hot and the outlet cool, heater core is plugged. Check the battery and the terminal cable connections. If they look really corroded, you need to clean the battery posts and cable connectors or replace the cables and try to start the engine. Also check the starter. The solenoid attached to the top of the starter can fail, as well as the components inside. NaHl.
