Hi guys,

 

Got an Mk2 Octy and have an issue with the self levelling headlights.

 

Been to one garage and they said that one of the sensors was the issue under the right wheel arch. had that replaced and had the same problem still - they're just pretty much pointing down and only lighting up the road about 4 feet in front of me.

 

Had it in with an Auto- Electrician today and he says the 5v electrical supply to both of my sensors keeps dropping so the system is going into a fail safe and just dropping the headlights. He believes the issue to be the Headlight Range module but didn't have time to locate where the module is and has no further availability until into the new year. I was hoping I may track down the said module (which he thinks is somewhere inside the centre console), find the right part and hopefully solve the issue cos it sounds like a massive job of disassembling the dash unless some of you lovely people have come across this and can point me in the right direction to locate this module without major invasive surgery??

 

Preferably answers on here but on a postcard will also be acceptable just as long as I can see a bit more of the road on a night that would be great!!

 

My Octy is 2009, 1968cc TDi Laurin & Klement edition. RHD.

 

Many thanks 🙂 

Did you have the car scanned for any possible fault codes stored?

Usually when there's a problem in the auto leveling or headlight range, the system will throw a message and will indicate the issue.

But not sure of any of the height sensors misfunctions would indicate a fault notice.

Unfortunately there's nothing been thrown up on the dash and neither of the garages have divulged what codes they're getting.

First garage said they were getting no communication with the front axle sensor so I had that replaced.

Second garage have rerouted the 5v power to try and bypass the issue but this worked for a couple of minutes then the headlights dropped back down on the failsafe. As I say they have routed this issue to this headlight range module within the centre console somewhere so whatever found code would lead you in this direction is what I presume they found??

Has the rear level sensor been checked too as there is one on the nearside rear but best to get a scan with someone with vcds as that will pin point the exact fault if it is electrical.  Can't really see much to go wrong other than the front and rear sensors as they are exposed to the elements.

Checks out as fine but loosing 5v to both sensors and supposedly this is due to this control module that I'm trying to find the location of??

Sorry about the intrusive banner line; go HERE for the full catalogue page.

Thanks for that info and it helped me do some more digging. Apparently the part I'm looking for is 1T0907357 and from a couple of forum posts I've managed to get some pointers on location. Some say behind the passenger side dash end cap - can't spot it there. Another has said behind the glovebox so had that stripped out this morning and still can't find what I'm looking for 😭😭😭

If you haven't found its location yet I am sure it is shown in one of the pictures in this Xenon FL retrofit by langers2k

Oh bugger, that looks like it's behind the stereo!! Looking in the completely wrong place! Cheers for that, hope it helps.

Right I found it!! MarkyD, your tip was the key - but it is a bugger to get to. If anyone else has this issue I will share the method.

 

It's behind the climate controls but the screws that it's held in with aren't very accessible so......

 

Remove the ashtray assembly (screws are under the gearstick cowel) behind there there are 2 screws which hold the sides of the centre console in place.

Remove the frame round the stereo and climate controls (start at the top cos it seemed to come out easier. 4 screws hold the climate controls in and then there's 3 plugs on the back to remove.

There's a screw holding each of the side panels in place then a few clips behind to free them off.

The module can be viewed in the void left by the climate controls being removed but you'll need to go in the sides to remove the 2 screws holding it in place.
