Hi All,

Recently had a problem with my front torque gauge where the needle is not moving and showing torque distribution to the fwd. So i assume it's running on rwd. The funny thing is that there's no 4WD error lights on and i check the rear attesa ecu, there's no red led light blinking, i have check the g sensor and the indicator is ok, not in red color, check the attesa rear reservoir when the ignition on, fluids on the right level. when i switch on the ignitiion on i can hear the attesa pump is working.

i recently changed the gear box oil and front diff oil. gear box oil i used redline heavy shockproof. front diff i sue the same oil as well. but after reading through this forum or gtro found that shockproof oil doesnt do well in diff, so i changed to castrol manual transmission oil, and problem still there.

so i am really confuse as where the problem lies or is the front torque gauge not working? othes gauges in the console working fine though.

Please help.

Thanks

you can try a bleed procedure just to see if the gauge works when the pump works. Take the drivers footwell trim out, there's a white plug that you unclip to activate the attessa bleed. Turn the ignition on (not engine), wait for fuel pump to finish priming (this might also be what you hear as I don't think the attessa pump primes on ignition) then unplug- you'll hear the attessa pump prime and the gauge should move too (up to half way). If your attessa system is not working and hasn't for a while the awd warning light can burn out- it should light up with the key turned to ignition.

Mate just because the g sensor indicator is showing ok doesn't mean that its working properly. The indicator is only a shock loading indicator and the sensor can still be faulty as this happened to me. Good luck with it anyway mate

the best bet now i think is do a bleed on the systems and see how it goes. Need to refer back to the manual for the full procedures. anybody knows which page? i did turn the ign on and unplug the two terminal on the g sensor and 4wd light pop out right after. plug it in the light still there and need to turn ign off and on then it's gone.

Have you had ur wheels balanced lately, or a wheel alignment?

Mine did the same thing after a dodgy alignment, the 4wd was definalty working cause I launched the thing hard on the highway lol

Anyway I didn't worry about it too much untill a couple of months later when I bought some new tyres and had a new alignment and balance etc then all of a sudden it started working again

If that doesn't help I've also posted the correct bleeding procedure in this thread

Good luck

nope, i triple check all four rims are 17x9jj off+15. even tyre size are the same 255/40R17. just that the rear tyres are newer than the front and i measured the tyres width with a ruler, the rear is wider around 0.5cm.

Might be same size, but if they are different manufacturer or different model by same manufacturer, then they could be slightly different. The width is generally "nominal". It's the rolling diameter / circumference that is important.

It was odd that you got the problem you had. Ordinarily, the symptoms would be a jerkiness in the AWD system, because ATTESSA sees the slightly smaller (older) rears "slipping"" relative to the (newer) fronts.

      I hope it's actually possible. This is a write off in insurance world.

      Yup. 2-way with shallow ramp angles. Still works.

      That was the first session so not a lot to take from the day. It was low 20s ambient and the coolant had got to 110 (and obviously had some pressure!) so that still needs to be addressed. I haven't downloaded the data yet but will. I had refilled the auto trans with Redline DT6 because it claimed the best viscosity I could find at 100o. It wasn't really long enough to get a good feel for that; while the trans got to 100o in the session it still wasn't shifting crisply as I hoped. I think I'll try a few more sessions before judging. No steering motor overheat but I'd hope not in only 1 session! But finally the suspension; it was night and day over the standard stuff and the car was a couple of seconds quicker on the same crappy tyres, which is a huge difference. I'll stick with that and get some sway bars and a mechanical diff sorted too and see how that all goes together

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      I guess it’s partially a compromise of how my car is used, wanting to be able to switch from drift to grip with track side on-car adjustment. Also partially with the way the knuckles are set there is more static camber but less dynamic camber gain.

      OK, so update from the track day on Friday It was a classic "an unfortunate series of events'. There were a few cars around and when i checked my mirror coming out of the fish hook I notice some smoke from the rear of mine. Looked again and it was getting much worse, I figured I'd blown a turbo or something to got off it and pulled off the racing line. However.... since it is a left hairpin into a right kink, I was on the inside of the next corner. There was a car passing me on the left and a big drop off over the ripple strip on the right......and someone had knocked the witch's hat that was on the apex about 1m onto the track. So, between those 3, I decided to mow down the cone and not damage my car/the other car. Right choice, but surprising result.  The car decided the cone was a small pedestrian so it blew the rear bonnet hinges up to protect their head in the upcoming person to car impact....I didn't see that coming and like an airbag deployment it happened super fast. Straight into the pits from there, everything was driving fine but it became clear it was a coolant leak not smoke, it was billowing up onto the windscreen. Onto the trailer and home. I'll do a separate thread about the repair (once I work out what it is ), but the immediate problem was the bonnet wouldn't open because the front was pinched onto the front bar and would not release. Ultimately we unbolted the hinge from the bonnet, pulled it back a little and it released from the front OK. "There's your problem", the top radiator hose had popped off at the radiator.
