Has anyone found a fix or attempted to fix the dodgy climate control display in the R32? Mine operates intermittently but much of the time parts of the display drop out or jumble. It seems to be worse with high cabin temperatures but can play up any time.

EDIT: Just thought I'd bring up this old thread of mine as I've got my climate control apart on the table right now and would like to know if anyone has fixed one successfully before and if so what did they find.

I had this problem. Some buttons didn't want to work either. Pulled it open and cleaned all the contacts and switches and stuff with contact cleaner and cotton buds. Worked perfectly for about 2 weeks then the buttons went abit intermittent but she works most of the time. Display works fine though

mine has a tendancy to not come on when i start the car, btu give it 30seconds and it will appear and all the buttons / display works perfectly after that. this only happens occasionally.

my theory is a loss of charge overnight and a bad solder joint rendering it incapable of getting enough current initially when i start.

i dunno...

my screen used to garble and drop out on the odd occasion but i think the whole lot shorted out. i turned the ac off and while the screen turned off what actually happened was the fan set itself to demist and i could not stop it. the next day when i turned the car on it set itself to demist again. what the??? after a couple of days it seemed to fix itself. i drove to work with the ac on - no problem. i turned the ac off before turning off the car - no problem. when i got back in the car 6 hours later the whole cabin smelt like burnt plastic. ive since pulled the fuse for the ac and the smell is gone but ive had no ac for a few weeks now. ive had a brief look behind the ac unit and all the wiring looks fine - no melted insulation. will try pulling the control unit apart and see if theres any burns in there. if there is how much would i expect to pay for a replacement? apparently the r33 unit is the same as the r32 unit. if this is true i will buy a 33 unit as its newer.

yeah mine also is a little tendancy to occationaly work then not work, often with a quick tap on the screen it works again......very stange, thou must be a loose connection somewhere. I'm going to have to pull the unit out and check the soldering. Also whats the deal with the button on it which when pressed shows some sort of Japanese writting and degrees? is that outside air temp or wot?

Bit off topic sorry but alot of the funtions also didn't work when i bought the car on the climate control but they guy gave me a pile of parts which he thought were the stock amps or something, a bit off lookin around i realised that one was the computer at the back of the car which seemed to fix both the HICAS and the climate control when i plugged it in.

The little Japanese writing says ambient i think, but you should be getting the temp as well. Perhaps the sensor is not working? Dont ask me where it is though, i dont know.

Yeah mine has a few funny things with it.  First, a couple buttons don't always work.  Secondly, the ambient temp button used to display the actual ambient temp when i got the car, but now all i get when i press it is some Japanese writing.......  Any ideas?

I pulled the control unit apart to look for anything a bit sus like dry solder joints or dirty contacts. 3 screws and the face unclips. 2 more screws and the front circuit board pulls off.

It is connected to the rear circuit board by a row of pins that push through a socket in the front board. This connection might be where some of the problems are.

I took out the 2 screws at the back and pulled out the back CB (tight). It looked like it had been resoldered before so I tidied it up and put the thing back together. I ran it for a few minutes and it performed like new so far. Fingers crossed.

Just pulled mine apart last night. everything looks fine so maybe mine is a prob with the wiring. will take it to an auto elec after ive payed rego. will let y'all know what the problem is so maybe can save the rest of you some money if you ever have the same prob. just hope it dont cost too much.

I think the AMB sensor is on the top of the dash, left hand side, very close to the window. Well its some sort of sensor

Ambient sensor is at the front of the car on the factory thermo fan.

As for not working.

Done a FMIC lately?, and removed it maybe.

i found some useful stuff on the climate control on this article, i think it was around page 30- 33 (diagnostic mode for the climate control, very interesting) would probally help alot of u guys find the problem with urs.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
