Pulled up at my girlfriends tonight after a short drive from my house (like 5 mins). Had warmed the car up before the trip and was just pulling to a stop when i noticed a weird sound. Doesnt go away when the clutch is in. Oil pressure is normal (i think its what it normal is at at idle)

Anyway it sounds metallic, kinda a rattle. Like when the powerballs go around in their clear sphere when the lotto is on tv lol. Its definitely from the turbo side of the engine, around the turbo somewhere. It can be heard from in the cabin (much clear then with the bonnet up), and its also clearer with the bonnet down listening with your head near the guard (cuts out the fan noise)

I did a search but nothing seemed to match what im after.

Car is manual, GTT, 60 thou on the clock. Cat back and pod, stocko boost.

Anyone else had this problem?

Its inconsistent, as in doesnt have a set rattle, it goes and comes and is not repetitive.

Maybe turbo bearing? Hopefully not engine bearing?

You gotta listen kinda hard to hear it with the bonnet up and that goes for in the cabin aswell.

Any help would be great/Ideas to try and rule out

so have you tried it yet grant? i only ask cuz i have the similar sound ur having hi-pitched metallic sound but very hard to hear in the open and can only hear when in an en-closed area like a garage... but the headlights on would make it alittle louder than it is..

      R32 GTS (RB20DE) Injectors Replacement

      By joshuaho96 · Posted

      Reading through the engine service manual their advice is do a cylinder balance test. Unplug one injector at a time and see if the idle drops a consistent RPM. You can also do this using a Consult cable which is easier. They also call for unplugging the power transistor, then with the engine off and the fuel rail unhooked from the manifold verifying that you have good fuel flow (even injection, no dripping/leaks, etc) when you twist the CAS by hand. Also verify the spark by pulling the spark plugs and allowing the plugs to ground and turning the CAS by hand. I would also start doing the sensor checks and idle valve checks in service manual. Make sure the MAF tests reasonably, the intake air regulator is sane, etc. You may have to get new spark plugs.

      This sounds very old of me, however since buying the Tiguan shit box, my view on shit boxes have changed.

      M35 Brake caliper replacement

      By Waders360 · Posted

      I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way

      This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.

      Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.
