Have you checked all three brake lights ONLY come on when the pedal is pressed and are not flickering on their own as you hit bumps? Or the switch rigged so that the slightest pedal movement set it?
Was the scan you started with the only faults? It only shows 1 of 3 ABS faults, what were the other 2?
The terminal 30 still points to a power issue, if battery good and terminals tight, the earths all good something is not right. Can not remember if terminal 30 is direct feed, fused or through a relay ( or combination ) and no access to wiring diagram presently.
Do you have a modified front left wiring loom on the brake wear and ABS? What tyres / wheels are you running as big ones can rub through the looms as they come down the struts.
Another possibility is the yaw sensor ( lateral sensor ) faulty, not sure if that has its own failure code in VCDS. as its been a while since I changed a faulty one.
I would also check the easy fixes first.
for example I have seen this issue resolved but clearing mud from the ABS rings on the wheel hubs.
of course that really shouldn’t cause the error but no harm in a visual check either.
Hi there Cenick ... this may be too simple an answer but I had a similar issue a couple of years ago ... ABS/ EML lighting up ... intermittent flashing but making the engine stutter and temporary loss of power and then it would clear and carry on as normal.
In my case it was a nothing more than a break in the wire that goes to the brake pad wear sensor at the pad end. It seems to have been hanging on by a thread, visually it looked fine and the insulation was still in place but when disconnected from the pad the wire had broken inside ... I think I damaged or stretched it reversing off a kerb .... I just cut it and taped the wire out of the way and the issues went away .... maybe too simple??
Slight edit .... I twisted the ends together and cable tied it out of the way ...
Check the wiring down both struts carefully all the way from the engine bay to the sensors, look for damage or previous repairs. Rescan with VCDS and give us ALL the faults ( except HVAC ). What wheels and tyres are you running now and previously - if known. Sounds to me like either wires shorting out or connections being lost or both. Brake wear should have no effect on this but if the combined loom is damaged or repaired could be the source. Best to jack the car up and remove the wheels. While wheels off check the wheel bearings and the ABS inductor rings.
OK so had a look at the codes. Have you had any work done on the car? Has the battery gone completely flat?
Remove the stop lights and clean the bulbs and their contacts to remove any contact corrosion.
Remove the plug from the ABS pump and check for damage or corrosion, clean plug and socket with contact cleaner. Somehow the ABS is not getting correct power.
So remove / check / replace the main earth under the headlight. Ensure the big fuse on the battery is tight.
01435 is the brake pressure sensor, again remove / check / clean this plug - sensor could be faulty.
Has the steering wheel been off? 00778 steering angle sensor broken, loose connector?
Steering wheel swapped? Steering angle sensor not set up correctly.
This is why it is important we know as much as possible about what has been done or not done.
Steering wheel should have been removed with the battery disconnected. Power should not have been restored until air bag refitted.
Steering, braking and brake pedal all cross feed into various systems that all need to be reset correctly. You will need at least registered lite or full fat VCDS now to reset the systems as they have lost their basic settings.
Disconnect the battery, remove the air bag then the steering wheel. Correctly set the steering angle sensor, make sure you are using the correct loom for your steering wheel. The SE loom is not suitable for the sport wheel. Rebuild the steering then reconnect the battery. Use VCDS to set things up and hopefully everything will now talk to each other and no warning lights. Remember to check the struts wiring.
