Good Evening all,

Hope you and your skodas are all well.

Few days ago i experienced strange situation where got 4 errors on dash:

• Stabilisation control (ESC) error

When i scanned my skoda with OBDeleven it found 11 errors below:

Is any one kind who could look at this and possibly advise what is wrong so i can get this fixed?

Thank you

Arek

To add to this, I'm aware of 2 errors:

Control unit: 08 Air Conditioning - B10AF04 - Air quality sensor Faulty - need to replace air sensor

Control unit: 5F Multimedia - B201A00 - Checking software version management - need to do confirmation installation in adaptations

The rest of them appeared recently

See my post in the "SOS" forum. I had the same thing a few days ago - dash like a Christmas tree and loads of unrelated errors (TPS, ACC, stability control, parking assist and more).

If you search on "U112300" one possible cause is low battery in the key fob, and there had been a couple of warnings for that but they'd stopped a few days before.

I replaced car battery and key fob batteries and nothing changed. Still getting same errors

Hi!

I experienced similar conditions to you. As you can see, all the faults are related to the wheel.

Stabilisation control (ESC) error.

Hill Hold Assist error.

'Front Assist unavailable' error.

Tyre pressure loss indicator error.

In my case, the cause was a bearing on the wheel. The bearing has a magnet on it so that the ABS sensor can measure the wheel speed. In my case, this magnet ring had become separated from the bearing.

WBR Primoz

Is it right to say:

1) It's legal to drive the car in spite of the warnings

2) It would fail an MOT (particularly for the brake / ESC ones).

Hi,

Did you open the bonnet and have a close look at your harnesses?

No sign of rodent attack? I faced similar problem on my wife's ex Audi Q3. Several DTC on non related components. 3 harnesses damaged and 25 bite marks! It took me a full sunday afternoon to weld everything and bring all systems back to normal.

Yes, you are right; the harness for abs senzors should be the first thing to check.

Today went to garage so can lift car and have better access to bottom parts.

After investigation i found out 99% possible issue of this errors.

Haldex ecu/module is heavily corroded inside.

Need to order replacement or get this one fixed.

Will update if replacement of module will resolve all issues.

Today replaced haldex control module and all errors gone. Hopefully forever

Hi,

Do you know the reason why the Haldex Control Unit got corroded inside?

Has it been submerged while crossing a river or reversing to launch a boat or a jet ski in the water?

Hi Bap33,

The car is 2017 and I'm second owner.

I have car for 6 years now and I was never crossing a river or reversing to drop off the boat to water.

I have no knowledge what was happening with car before I got it.

But I'm pretty sure if some of above happened in 1st 3 years corrosion would develop quicker.

When I opened faulty module half of it was white/crystals corrosion suggesting salt.

Maybe over time red gasket used to seal module losing it's watertightnes.

Unfortunately I don't have any photos as we were trying to get it cleaned and repaired.

Only visible damage what has been done on pcb was corroded 2 pins of tja1042t high-speed CAN transceiver which disappeared after cleaning.

Son in laws old caddy 4motion was the same. Spoke to Haldex specialist and they said its common on older vehicles. Its normally just the connector to Haldex but also water ingress due to age/failing seal and where the unit is mounted on the car.

Alasdair

Thanks for the feedback.

My previous car was a 4x4 Superb Estate Mk3. I kept it for ~8.5 years I fortunately had no issue with Haldex.

Climate is pretty fair where I live and roads are rarely salted. I used to clean the bottom of the car with HPC after each period of road salting. This may helped avoiding corrosion.

I keep on doing this on my current 4x4 Kodiaq Mk1

Saying that his caddy was ex brittish gas and had 200k plus on it. When it went it caused all manner of problems with warning lights and drive issues.

Alasdair

As I mentioned I currently have the whole cascade of faults (stability control, parking assist, headlight range, hill-hold assist, TPMS and maybe more).

Dealer just called to confirm it's an ABS / wheel sensor fault. Glad I have the extended service + warranty package

I have this too - all of the lights, but only some of the time!

New battery and a new rear near-side speed sensor fitted (battery was past its best anyway) and still seeing the intermittent problem.

I suspect it's the ABS ring as others described. One thing of note, is that my errors tend to pop-up immediately after starting - even before the car has moved.

Could be a failing bearing/sensor ring as you mentioned but the fact it does it before moving may point to a wiring fault rather than sensor/sensor ring. Might be worth checking connector on sensor that was replaced and trace back wiring looking for damage.

Alasdair

Mine gave all the errors as soon as I touched the Start button. Replacing an ABS sensor fixed everything.

Hi

If you are assuming an ABS sensor, then there could be two possibilities:

1.The sensor has failed, meaning that the on-board computer detects this when the start button is pressed. This failure will also be recorded in the log file when you scan for failures using OBD or another OBD scanner. In this case, check the connection plugs or replace the sensor.

2.The second possibility is that the sensor is not faulty, but the magnet layer on the wheel bearing has fallen off or broken. In this case, a warning will appear when the wheel starts to spin. I have experienced this issue. I need to replace the wheel bearing.

I hope that helps.
