Hi everyone, pretty new to this forum but had Audi/VW/Seat for last 3 cars so some experience of them
Recently our A4 lost power during a trip - literally after coming off a roundabout, it wouldn't rev past 2500rpm. At the time it felt like a limp mode and didn't want us to rev it. Nursing it home, if we pulled away and revved through the gears slowly and with gradual acceleration, it would rev around a lot further, basically as far as we'd ever rev to anyway before changing gear. The main difference here was it was clear that it had no power as acceleration could only be done slowly.
Whilst only accelerating this way, at the point the turbo would normally kick in and boost acceleration greatly (around 2500rpm), there was no whistle or change other than MUCH louder revving, almost like thrashing an old non turbo van or similar.
It has been on a scanner at a garage (the mechanic actually told me before looking or seeing it at all that it was "probably the waste gate") but came up with "Needle Lift Sensor".
I've read lots of threads on here an elsewhere all with slightly differing views and issues (but none mentioning this loud engine sound once the turbo should be working).
Rather than buy a replacement Needle Lift Sensor/Injector at £200-£300 (the car is now on 170k and cosmetically not the best so I don't want to spend a fortune on it for parts that might not solve the issue) - I thought I'd see if anyone else had had the same problem/knew what else it sounds like it could be.
Thank you so much in advance - so desperately need my power back as it's a bit embarrassing pulling out at junctions!
