Can you ground the amplifier directly to the hu using a jump lead just for testing purposes.
this is a common issue of noise suppression on alternator whine but sounds like you also have the RCA cable problems separately too.
have you used twisted pair RCA cable not just changing the cable
You’re issue IS inherany a ground loop.
This is proven since used your mobile phone to the RCA (phone is not connected to the vehicle ground since it uses its own battery) and there therefore no loop created, you had no sound issue
Hence using a headunit which shares the same power...
I connected it elsewhere too, as long as it’s ground it is ok.
there was some truck to do with connecting to ground then removing it, it was a right faf. Keep playing with it, the length of the wire wouldn’t be the issue
I did it 4 years ago so don’t remember the technicality but haven’t...
It’s not you, it’s a PITA to get to work it’s to do with connecting the wire to ground, had a similar issue many years ago eventually it worked.
Don’t think the cluster has nothing to do with this I believe
Practicality beats all, homemade.
Phone mount. It’s the best location for me since it’s not hitting against my legs if attached to the garb handle like some Brodit designed I’ve seen, nor is mounted too far away by the air vents. It only covers volume control which I never use thanks to the...
Replace exhaust gasket and Turbo to DPF gasket, no need to replace the clamp. Use dark side developments if you cannot find the parts although 95% of things are available via Audi/Vw.
And don’t neglect turbo oil pipes, return normally requires a new banjo bolt and a decent shallow 27mm socket...
No that is correct, the pipes are cut like this
atmosphroc pressure is the reference for the differential pressure sensor, all the 2nd gen and onwards cars use the sensor in this configuration.
Only the older ones from 2007-2008 have pipes going to both sides of the dpf
