GD STI DCCD/ABS Fault?


Recommended Posts

* SEEKING INSIGHT/KNOWLEDGE **

So as of a couply weeks ago or so my Version 9 STI decided to take a nice steamy S*** on me and do what it does best and start to fault and run me up the wall with possibilities on what's actually wrong ...

 

So I'm having some issues with my DCCD/ABS system ( I think? ) - my symptoms are that car just started off with slight clunking in rear on take off ... turning to straight up binding/shuddering from the rear when taking off in low gears/turning ( was quite noticeable st this point ) ... turning into what feels like my car is towing a trailer in the rear... ( all in AUTO DCCD setting )

 

Just came back from slight fault finding mission... car was not binding - well not that I could notice in low gears on full lock.. both in AUTO and Manual mode all the way down. But though when traveling straight the car just felt unpleasant to drive in rear... no noises but felt like something was holding it back... felt like towing a trailer or something clamping down on it.

 

I have noticed also recently my brake pedal has got super hard.. I have no whining at all and problem is intermittent. I'm assuming my DCCD controller is working as should as o can select the manual modes and feel the difference in drivetrain.. but same problem persists. Now I'm sure it'll bind and clunk again but it comes and goes.

 

Am leaning towards possibly ABS fault? Have read that the DCCD system runs off the abs sensors in the hubs. So am going to rip of all ABS sensors and clean them and check the Ohms with a multimeter to assure they're working fine and fingers crossed... will also bleeding brakes this weekend as the pedal is quite hard.. 

 

But for the meanwhile does anyone have any suggestions or ideas what it could be? Definitely feel it all in rear and something to do with DCCD/ABS.

Anyone had experience or can shine light? Would appreciate!

Cheers

for now chuck it all the way open and drive with it in manual mode. take it to a subaru dealer or specialist near you to check for codes in the ABS system, You'll get an ABS light if it is an abs fault though

Hey bud! Yeah been driving it in full open.. still symptoms persist come and go with it but am doing it to be easier on the system anyways. I approached my local dealer and they said they have no interest or confidence in tackling high performance Subarus and weren't too happy to take it.. plus their labor rates start at 105$/phr +GST i think last i talked? 

 

Don't have a direct Subaru dealership here just a motorgroup which sells a couple.. .Have been in touch with S.A.S in ChCh and am going to transport it their way down from Queenstown if all comes to halt and still am left head scratching after weeekend.. just trying to do as much as i can myself and shine some light to make it easier for anyone/everyone who will get involved in sorted this.

 

Yeah no ABS light so maybe i'm SOL on that idea.. i will try however do it anyways so can cross that off the list.

Hmn, a dealership shouldnt have to worry about high performance if it is a repair issue; It's not like it's too different. is the binding only when turning? sounds like the centre diff is packing it in tbh

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
