Hello there, have tried posting my problem in the transmission section but no luck.

My power steering pump seal went, PS fluid everywhere. Mechanic fixed the PS pump, now I have a metal grinding noise in 4th gear at 1500 - 1800 rpm under light throttle (could be a coincidence) Rear diff rebuilt, pulled the 4WD fuse, still no luck, seems to be coming from middle of car? Unable to get a recording of the noise unfortunately. Had some mechanics who work on race cars spend some time trying to track it down but they couldn’t figure it out.

Any help would be appreciated.

You didn't have "no luck". No-one is going to be able to identify the very random problem that you have. You are going to have to do actual diagnostic work.

Put a go pro under it and go for a drive. Run it on the dyno. Tape a microphone under the car in various locations until you get an increase in volume. Etc.

not a gtr though, a ford falcon wagon, but had a light metal rattle sound on light throttle aswell, sounded like it was coming from the motor/trans. Turned out to be the starter not retracting back properly and just freeplaying. Could be it? May not. Just thought i'd share.

      No map light, dome light or trunk light after bulb change

      By b0nb0n · Posted

      Hey all new owner here from the states.  Just received my RS FOUR S last week. Went to replace some interior bulbs with LEDs this morning and after changing the first map light bulb I lost all lights to the map lights in front of the rear view mirror, middle dome light, rear trunk light and also the ring light around the ignition. They do not work manually, when the keyless entry is used or when you open the door.   Everything else is still functioning like the head lights, fog lights, cluster, radio etc. I tried replacing the LEDs with the original bulbs but no luck.   I replaced every fuse in the under dash fuse box to be safe, most looked original but none busted. While changing the fuses I noticed the TCM box was loose and could wiggle it around. Not sure if it's related or I just shorted something out while replacing the bulbs. I foolishly did not disconnect the battery prior.   At a loss here, couldn't find any similar cases to mine. I will try to check for continuity tomorrow as a last resort.   Any advice is much appreciated. Thanks in advance.

      The viscosity is about right for Dexron III/Matic D.

      Check the wiring behind the headlight that connects back to the engine harness (assuming the stagea's layout is similar) That plug should supply IGN power to the harness from what I remember.

      Thanks... yeop I think anyone thats had to compete or travel more than the usual home track situation gets it and prob even those that havent yet had to do it ... its just harder and costs more fullstop As one goes through this, prob like yourself, you gain and appreciation of effort - almost regardless of the result - but the result can add to it on top This year I did enjoy it alot more even though it was harder ...which is actually good!

      Hey Matt, no I think I've misled you...I'm not sure that the ECCS power supply to ECU had 9.5v, just that the ECU reported 9.5v.   Link got back to me pretty quick and suggested to check the IGN power supplies to the ECU Pin 24 is the IGN key signal, which is working OK (ie battery volts with key on IGN) Pin 31 is "IGN power supply" and sure enough that is giving 0v with IGN on So, back to a car side problem, which is good because at least I can work it out here. On the down side I don't have a wiring diagram for Stagea so its the old fashioned trace and check task. @Stick180 I did double check those fuses are OK (I double checked all IGN fuses) and I also pulled and swapped the IGN relays at the driver's knee as a quick check with no change....but something is wrong there somewhere
