Trying to fix my mom's car has the cel code above I can hear a hissing sound coming from behind the engine if I remove the supercharger cover. I'm assuming it's a v8 since it's supercharged. I tried spraying water around the area but can't get a idle change f I watch the fuel trims it doesn't improve with rpm so what ever it is is constantly leaking. Don't know if it's vacuum or pressure but I'm assuming vacuum since the ECU is reading excess air. I attached some freeze frame data pids. Thanks for the help in advanced.
I was finally able to find the vacuum leak theres a pipe about an 1¼" diameter with ribs. Found a small crack where it connects behind the super charger. You can see where I put some gasket maker to help seal. Any one know what this pipe goes to?
Symposer
Historically, automobile manufacturers have focused on
reducing the level of engine acoustics within the cabin.
With the introduction of the new 5.0-liter V8 engine,
development engineers have deliberately accentuated the
acoustic feedback into the cabin in an effort to further
increase the driving experience.
An integral part of this development is the introduction of
a symposer into the engine air intake system of the SC
engine. The symposer is mounted on the rear of the engine
and is connected directly to the RH intake manifold.
Engine order pulsations from the intake system are fed
into the symposer, which picks out the pulsations that are
within the target frequency range. These accentuated V8
engine acoustics are then directed into the cabin.
The symposer is a mechanical device that is operational
when the engine is running. However, a vacuum operated
valve, which is controlled by the ECM, only allows the
acoustics into the cabin under certain conditions. This is to
achieve the desired engine sound quality in the cabin.
This is the exact issue I'm facing with same hissing sound from left side of supercharger on 2017 F-Pace 35t, has anyone resolved this issue? is really hissing sound the problem? I'm douting on gasket or should I need to keep searching for leak other places?
104750 Miles, I got repaired some coolant things some time ago, There was a leak on coolant thermostate and coolant hose (connected to radiator) connected to front of engine was not leaking(so I assume they must have removed it and put it back), eventually after repair check engine light came around 4 weeks later
Hopefully you're working with a good JLR independent. Check with them if that is the symposer connection. I thought only F Types got symposers but I could easily be wrong. If it is, you can remove the hose and put in a port block that LR's get.( They don't get symposers).
If you haven't yet changed out the Y pipe up front and the manifold pipe in the back you might want to do that at the same time. While the supercharger is off have then change the oil in it.
they are local good service provider but not Jagaur specialist, it's very remote area in southern USA,
I appreciate your suggestion, I would give a try to see your suggestions or find a JLR specialist.
