Steering rack woes.....

So rack all changed and now and I think all coded with vcds I do have an error in the and tho which is:

Address 03: ABS Brakes        Labels: 1K0-907-379-MK60-F.lbl
   Part No SW: 1K0 907 379 AC    HW: 1K0 907 379 AC
   Component: ESP FRONT MK60      0101
   Revision: 00H11001   
   Coding: 0004738
   Shop #: WSC 01279 785 00200
   VCID: 73E513951245D186965-8026
 
1 Fault Found:
01309 - Power Steering Control Module (J500)
            008 - Implausible Signal
 

Which according to according the Ross tech website means ;

01309 - Power Steering Control Module (J500): Implausible Signal
Possible Symptoms
Malfunction Indicator Light (MIL) active
Possible Causes
When found in Brake Electronics (MK60)
Incorrect Steering Aid Characteristic Setting
Incorrect Steering Aid Warning Lamp Setting
Driver Steering Recommendation (DSR) in activated in Brake Electronics but not in the Steering Aid Control Module or vice versa.
Possible Solutions
When found in Brake Electronics (MK60)
Check Brake Electronics Coding
Check Steering Aid Characteristic Setting
Check Steering Aid Warning Lamp Setting
Check Driver Steering Recommendation (DSR) Setting

So I guess that answer the question I need to get the steering characteristics coded at VW, I have booked an appointment there on Friday after work so I can make sure I watch the techey do it, and check it's not coming up with errors in VCDS!

New subframe bolts all round to be fitted when I do the alignment with new steering rack ends. Il
Make a note l if there's any improved steering feel. I know there should be less catch up from previous testing... Should be interesting! Thanks for all the help!

Had my steering rack replaced at the start of this year for a new Gen3 and have the same error code since. After 3 months and 4-5k miles i've not had any problems :)

As long as it has been coded properly and the steering angle adaption has been done (if needed) it shouldn't cause a problem.

SI-R32:
But you need the right steering curve loaded at VW for your car to give you various stiffness for various cars, you can't just swap over and bobs ya uncle

Donx22:
Hey Degudodger, I'd get your steering adaption looked at by VW it's not something anyone but a VW garage can chnage, the rack will need to be reflash end so it knows what new vehicle it is in. Normall procedure after replacing the rack, it's not something that can be done with VCDS, you may not need this if the rack was from the same model and variant etc but from the sound of it it wasn't like mine.

My steering is super light, very springy and has no return damping, not what you want on a gti, also the steering characteristics also take into account the front end vehicle weight, so your steetomg efforts are not going to be correct.

Il let you know how it goes at the stealers next week to get the  reflash  but I would defiantly advice having it done.   :happy2:

Donx22:
Hey guys, so I had the reflag on Monday morning. The tech couldn't work out heat needed doing so I ended up just using their system and flashing it myself  :happy2: and not having to pay is always a bonus :wink:
What need to be done is the the new steering characteristics for adaption has to be uploaded from VW main system.

Once plugged into the diagnostics it worked out the can level and updated the steering to gti setting, much smoother on centre now weights up nicely at speed, the new settings on variant 3 rack have slightly kore damping at higher speeds and less catchup up in the steering rack, definitely a good upgrade, not necessarily one I would do unless have to but it would defiantly be advised to get the variant 3 rack over 2 if you where ever in the situation 2.

I have some steering plot graphs that I will try upload later between mk5 and mk6 settings showing the steering catchup improvement, il have to have a look thru the data to see if there is any improvement to the damping but subjectively it does feel a lot better, the slightly elastic feel il closer to the limit is now barely noticeable unless you are trying to to do a subjective assessment!  :driver:

Overall good result and if be happy to help anyone regarding any questions.
I would say its not a necessity to get the steering reflashed if you haven't and have done a rack change but it is defiantly worth while if you like an improved steering feel, better feedback and noticeably improved high speed steering input response.  :happy2:
