check if there is a leak under the power steering resivoir..(??) the little bottle which has redish liquid inside... also check how much inside, should be neary full.... i dunno about r32s, (because I dont like them) but in my r33 it had a different diff and there was also a power steering fluid bottle in the boot .. if you have one of these (dont think you would) check it too

The HICAS controlles the power stearing, there is a high speed and low speed mode. If the speed wire is cut it get's stuck in high speed mode. I had the same prob, I soldered a bridge wire from the speedo to the HICAS speed sensor wire.

The best way to test is to get a multi meter. the HICAS box in the boot (on the drivers side in my car) has a yellow wire with a green trace, if you unplug the conector and put a probe with a extention wire on it, and put the lead round to the drivers seat. Now you need to pull out the speedo, there should be 3 plugs in the back of it. on the middle plug is the other end of the yellow/green wire. Put the other end of the probe there, and put the multimeter on resistance mode. If you get a reading your wire is fine. if not you have to find where the break is.

I wouldn't wast too much time with HICAS, a locking bar might be the best solution and just get rid of it.

At high speed,active HICAS can make the car feel pretty nervous.

more scary when it dosn't work, and moves under high force, or bumps in the road.

I am experiencing exactly what you are experiencing Drift Squad except the Hicas subframe has been removed on my R32 GTR i.e. no more Hicas. The ECU has also been reprogrammed/chipped. The hoses were also plumbed back from where the Hicas was removed.

The car has power steering for the first few minutes and then reasonably quickly the steering becomes heavy at which time the Hicas light comes on until the car is turned off. When it is started again the above symptoms are repeated.

Any ideas?

HICAS has been covered to death on this forum. A search would have told you everything you need :P

Yes, it can be fixed (assuming the mechanicals and electronics aren't damaged). Usually its one of the following or a combination (in rough order of occurence):

1) Low powersteering fluid.

2) Aftermarket steering wheel with wrong or incorrectly installed BOSS kit.

3) Poor wheel alignment.

4) Speed sensor wire has been cut.

5) Leaking powersteering hoses.

ah, the BOSS kit BTW is HBK ON-115, not the ON-110

The ON-110 is for the NON-HICAS GTS-ts (and GTS4's I think)

The ON-115 is compatible with HICAS

incorrect

if it comes with the plug its compatible and it does

last night i changed my steering wheel and when i fitted the new 1 its slightly off centre, it caused the light to come on...

easy fix though.

      Cheers. I more want it quieter with the varex open. I only have the varex closed when i start up and roll out the driveway to keep everyone happy on days i take the car to work at 5 AM or come home late. So just a mod muffler will do tge trick? Something like that would require a retune hey?

      I was going to say generally speaking if it's like 80k+ miles since the valve cover has been replaced you don't even attempt to just replace the gasket. The valve cover itself will likely be warped and it will continue to leak after replacement, just not as severely. The valve cover PCV diaphragm can also tear and create a major vacuum leak. Welcome to BMW life. My friend's 2006 330i was t-boned and totaled out so he also just got a 335i so I can add to this thread now.

      Odometer LCD is Intermittently Wonky

      By Kip · Posted

      Hi all, For my '98 260rs... The odometer LCD occasionally turns blank or gives me only the bottom half or top half of the numbers. It's intermittent, which leaves me to believe it's a dead solder or loose wire somewhere. The odometer itself works. When the screen comes back, kms have been added to the trip and overall meters. A couple questions: Is this a known issue with the Stagea? I didn't see it pop up in my quick search, but that could be my searching skills. How accessible is the LCD screen in the cluster? I'm hoping it's a remove and replace type situation versus cracking open the whole housing. I'm hoping you all can narrow some of my initial troubleshooting. Any experience or opinions would be helpful.

      Yeah. Seeing the finish line must be quite the motivation. Good on you for sticking with it. Understood about the model choice. Also, totally get the challenge with sourcing parts. Based on your handle, I'm just a few hours south of you. All the little things I've bought so far come with $30 shipping, even if it's just stickers for the boot!

      Go to SP mufflers and get the muffler of size you want and make a nice mid muffler. It's about that simple! I have 2x 3.5 Magnaflow straight through Mufflers and while it's pretty loud with the Varex open, it's quiet enough with the Varex closed. You can also buy off the shelf Magnaflow straight through mufflers as well. You also have a turbo to quiet the car down too. Don't overthink it. Buy my extra Magnaflow muffler sitting on a shelf doing nothing (buy it new, ignore this part)
