Couple R32 Issues

[confuzion]

Hey guys,

have a couple minor problems i need advice with or where to start looking, ive searched but cant find anything on each question..

This is for a R32 GTR

1) Brakes - They are hell spongy like they have air in them but they have been bled apparently. We replaced the master cylinder with a new one and then bled it again and its still spongy. Could it be the brake booster or?

2) Ticking sound at rear - When the key is in the On position, or when the car is started/running i can hear a 'click' under the car and the lights flicker at the same time as the click. When the car is first started it happens more often about 5 seconds apart, when its running it doesnt really happen while driving or i cant hear it anyway.

* When i take the 4wd fuse out there will be no clicking what soever and the lights wont flicker either, so im assuming its to do with the attessa system or ABS.

* i got underneath and i cant really tell but it sounds like its either near the diff or fuel tank (surely fuel pump wouldnt make lights flicker etc?)

3) Aircon - The aircon/vents only point to the window now, they used to move around like normal when the mode was changed, but now they only stay in the demister position and you cant hear the motor trying to move them.

Any help is appreciated guys Cheers

Mine was the same when i first imported it, machined brake disks and new fluid helped the problem a bit, and some hard stopping helped the problem a bit more, i suspect that rust from the disks that accumulated during shipping embedded into the pads. im still not happy with it tho, and i doubt i will be till i get around to getting some new DBA rotors and some good quality pads. if it was me i would try new fluid (if you havent already), then machine the disks (if they seem warped), then check all the calipers are working correctly, if thats all ok better pads with more bite might improve the feel. if everythings working properly they should stop well.

When the car is first started it happens more often about 5 seconds apart, when its running it doesnt really happen while driving or i cant hear it anyway.

I can also head a click/tick noise when i have it on the on pos every probably 5-10 seconds, i havent noticed it while the car is running tho, just when its on ON, but not running, i havent really listened either but im not concerned about it.

3) Aircon - The aircon/vents only point to the window now, they used to move around like normal when the mode was changed, but now they only stay in the demister position and you cant hear the motor trying to move them.

take to auto electrician/ buy new parts from a wrecker and fit them

they are just my suggestions i hope its of help

[confuzion]

thanks dude, i have actually had the brakes serviced when it arrived as like yours there was rust on the discs, so they were all machined and bendix ultimates and metal kings where put on, plus now the master cylinder changed, so im thinking its either air which i doubt or booster at a guess..

cheers

Hardly. These are quite common problems.

1. Check your brake lines. Make sure your using a quality DOT5.1 oil.

2. I did some investigating on this. Its a relay in the boot clicking on/off. Its for the 4WD or HICAS (I forget which -- I posted up some details you can search for if you really care).

3. Does the climate control display reflect the (supposed) change in position?

[confuzion]

1. Very sure were using the 5.1DOT fluid i shall double check.

2. A friend suggested it sounded like a relay also. Is it anything to worry about/can it be fixed? Just looks kinda dodgy sitting there idling and my headlights flicker at the time of the click.

3. The climate control displays the change in position yes (eg floor or straight forward)

1. Well I would check your lines. Its not uncommon for them to perish over time. Also, how tightly secured is the master cylinder?

2. I find the interior lights dim momentarily: can't say I've noticed the headlight dimming too. Either way, if its just the relay its normal. I've often wondered if a better battery or one of those earthing kits would help.

3. No idea then. Have you tried the error codes on the climate control?

[confuzion]

3. I have and it flashed the code 31 32 34 35 36 or whatever it is, which states that a 'connecter' is unplugged. I have pulled the whole freaken dash apart and traced everything i can and i cant find any connecter or wire unplugged. It will probably have to be a sparky's job

Thanks for replying dude ill check the lines etc B)

[lwells]

Have you tried the fuses for the climate control? There are three IIRC.

[blind_elk]

The clicking sound is, I believe, a relay that activates the HICAS system to keep fluid pressure up in the system. It's supposed to happen, AFAIK. The radio usually drowns out the sound.

[confuzion]

bloody hicas, another reason to get rid of it

will try the fuses tomorrow cheers

There is a connector in the engine bay, basically immediately behind the coil ignitor module. It connects to a sensor that clamps around one of the heater pipes back there.

This one? (attached). Shes plugged in Ive checked all fuses in the engine bay and the inside fuses too :|

[blind_elk]

That's the one. Certainly looks OK. Although the sensor itself may have failed.

A/C diagnostics don't flash codes, they display them on the facia panel.

[confuzion]

yeah thats what i mean, in diagnostic mode the unit flashes something like '31 32 34 35 36' which in the R32 service manual and also what a search brings up means a connecter seems to be unplugged..

grrr summer is coming up

brakes. have you bled the abs as well?

there is a special sequence to bleed, can't remember it off hand, follow gtr workshop manual. if that fails get a pressure bleed done on system, this should force out any air hiding away.

ticking noise at rear. could be hicas or attessa. check Attessa resovoir in right hand rear guard (remove small interior trim), should be done with ignition on, and level should be between marks. normally when you start car, the attessa pump should prime the system so that there is adequate pressure that can be applied to clutch packs for 4wd system when it is required.

check power steering fluid levels, same fluid resovior used for front and rear steering racks -for R32s.

maybe fuel pump is on way out?? is fuel pressure ok?

[confuzion]

ok brakes !

with the car off and me pumping the brakes, the first pump is squishy then every other pump is hard like it should be

with the car ON and idling with me pumping every pump i hear a PSSH and obviously its squishy. It sounds like its from inside or in/outside the firewall so im assuming the booster is leaking?

[confuzion]

Ok bled the brakes on the weekend - no difference still spongy

the pssh noise when pressing pedal i found is normal in other cars ive driven latley if you listen closely and push hard repeatedly
