My Octavia 2014 vRS TDi 184PS has been throwing a warning for a while for AFS cornering light error.

Scanning the codes I have C1034-15 Left Front Level Control Sensor Open Circuit or SC-Battery

 

I have found the sensor on the front wheel assembly & was looking to replace it.

I believe the part number is: 5Q0 412 521 C

I've found the part on Skoda-Parts.com & there are 3 versions:

• Skoda Genuine €200
• OE Producer (EU) €103
• EU After-markert €43

 

I'm guessing there's no point to buy the Skoda part over the OE part as they are identical except for branding.

 

What are peoples thoughts on the "AfterMarket" part vs OE Producer part ?

As they are from "Europe" Id assume its not a chinese part but manfacturered in europe as an aftermarket part.

I will take a quick check of the electrical connector before I order the part.

 

Are there any things I should look out for when changing this part ?
It seems pretty easy to do with the wheel off -> 3 bolts & the electrical connector..

Id hope I don't need to reprogram or relearn anything after replacement as its automatic at every ignition-on.

 

 

This is the part I ordered:

Headlamp Level Sensor Europen Union - OE producer 5Q0412521C

As Switzerland is outside the EU, it is only €84 + 8% = ~€90

 

Will post an update on the manufacturer & fitted when it arrives...

Short update for anyone that find this post in the future.

I changed the sensor & the fault has gone. The sensor itself was completely seized & I'm surprised it hadn't snapped already.

 

The job is really easy to do (1 nut, 1 bolt & the electrical connector which was actually the hardest part to remove 😁)

 

I saved myself around 400CHF for 30minutes work & 85CHF from Skoda-parts so I am quite happy....

 

 

The New Part

The Part that I ordered was supposed to be the "OEM aftermarket" part.

The packaging had no indication of manufacturer but it does have the VW logo & part number stamped on it.

 

Changing the Part:

Changing the part was very easy. I removed the wheel for easy access but if you have a ramp you probably don't need to do this.

There is a 10mm hex bolt fixing the lower part of the sensor & a 10mm hex screw to fit the upper part to the body.

Access to them is very easy.

 

New Part Installed & Electrical Connector

To remove the electrical connector, push the small tag at the top inwards (you can hear a small click).
I found that pushing hard down on the sensor before giving it a good tug upwards allowed the plastic lock to release.

The internals of the connector were clean but around the outer exterior parts there was lots of dust/salt/dirt which drops out when you lift it up so its best to give it a good "blow" before refitting the new sensor to avoid anything dropping inside the new part when installing it.
