This relates to a 2009 Skoda Superb 1.9 TDI BXE but I'm posting here as it's code related and from my Googling it isn't a Superb specific issue as it seems quite common across the VAG group.

 

Got ABS warning lights on dash. Scan indicated the below two codes:

 

• 01316 - ABS Control Module (Parking/Steering Assist)
• 01435 - Brake Pressure Sensor (ABS)

 

Got a refurbished ABS Control Control Unit / Module and mechanic fitted it. However, after fitting it the below codes are now shown (new codes in bold):

 

• 01435 - Brake Pressure Sensor (ABS) - so this code hasn't gone away
• 01279 – Longitudinal accelerator sensor, no or wrong adaptation
• 00778 – Steering angle sensor, no or wrong adaptation
• 01423 – Lateral accelerator sensor

 

They said when installing the refurbished ABS unit that the part number was exactly the same as those on unit that came off my car so it has to be the right part. They said it required a code after installing it and the code from the old unit was entered and accepted. I can't remember if they said the 01316 fault cleared or not but they were wondering if the refurbished unit is faulty.

 

Overall, they said they're a bit flummoxed by the above codes and can't figure out if the issue is with the refurbished unit being faulty or whether there is some calibration/coding issue they need to do but they don't seem to know what to do. In total they've put 4 hours into this and naturally I've paid for those four hours of labour so far - I've no issue with that obviously as they're not a charity but naturally don't want to keep throwing money at it.  It's with an indy and they're following up with a link they have in VW about it.

 

In the meantime, from searching, the ABS issue seems extremely common, however I've only so far come across one experience identical to mine here on Briskoda (link here). From that post there seems to be two routes to follow:

 

1. VCDS Basic Settings: In that post the issue was resolved by the garage reprogramming / performing the basic setting procedure with VCDS. I'm pretty sure they would have tried this as they did mention entering a code that was accepted by the car/ecu/whatever it is that 'accepts' codes.
2. Battery Related: Someone in that post asked about whether the battery had been disconnected at some stage, and I had disconnected the battery just before I brought it to the indy because I was repairing the boot wiring loom which had recently broken. Would disconnecting the battery have caused these faults? The person in that post hadn't done anything with their battery so there was no detail on the link between the battery being disconnected and these faults.

 

Presuming they did the proper reprogramming, how might me disconnecting the battery have caused these faults? Is there something I can do to try to reset them?

 

EDIT: As an aside, I have seen it mentioned that VW and Skoda UK have repaired the ABS issue free of charge regardless of service history (as per comments in this post in 2014). I'm in Ireland but I hope this isn't still potentially a free of charge fix from Skoda that I've just thrown the best part of €400 at in total so far...

The initial 01435 code can be various things: http://wiki.ross-tech.com/wiki/index.php/01435

 

A full VCDS autoscan would confirm which and give a better idea as to what is needed to fix it.

 

The three new codes could just be a lack of adaption/basic settings. Again, a full autoscan would give a better idea.

 

At a guess, you need to figure out what's causing the 01435 code and then follow this: http://wiki.ross-tech.com/wiki/index.php/VW_Golf_(1K)_Brake_Electronics_(MK60EC1)

Cheers langers2k, the basic setting headings in that link showing the steps to follow for the MK60EC1 coding literally mirror the error codes I'm getting...

• Car fault code: 00778 – Steering angle sensor, no or wrong adaptation
• Ross-Tech coding: Sensor for Steering Angle (G85)

• Car fault code: 01423 – Lateral accelerator sensor
• Ross-Tech coding: Lateral Acceleration Sensor (G200)

• Car fault code: 01435 - Brake Pressure Sensor (ABS) 
• Ross-Tech coding: Brake Pressure Sensor 1 (G201)

• Car fault code: 01279 – Longitudinal accelerator sensor, no or wrong adaptation
• Ross-Tech coding: Longitudinal Acceleration Sensor (G251)

If the original ABS warning code is gone (01316), would that suggest perhaps the indy isn't aware of how to recode the new (refurbished) ABS unit given the four codes perfectly match the ross-tech coding procedure? From a quick Google, the scanning unit they had looked like one of those snap-on ones (link to scanner that looked like the one they were using) - probably impossible to know without knowing what exact scanner they're using but would that type of scanner typically not be able to do the required coding?

 

If the original ABS warning code was still showing after the refurbished unit was installed, would that suggest the fault is with the new/refurbished unit?

So a brief call today indicates they don't have VCDS and are linking with a person that has "VW specific diagnostic software", which I'm guessing might be VCDS.

 

If all they have is a Snap On, is that able to carry out the same coding / functionality as the VCDS? Would they have been able to follow the recommended steps from Ross-Tech on what to after after installing a new/refurbished ABS module using Snap On?

I would imagine the Snap On tool can do it although I've no idea how as I've never used one...

 

The garage might need to contact Snap On for support
