Hi there!

I recently installed on my car an OEM Electric tow bar on my 1.5, but pressing the button inside the trunk, nothing comes out from under the boot.

According to Skoda workshop, problem was the control unit: it was the model specific for electric cars with part number Skoda 5H2907383B; in fact looking on VAG the right code for my car is the 5H2907383BLc.

I found a pre-owned one over eBay and when mechanic connected it and turned car on, it enlightened itself for awhile. Is it matter of dataset or what else?

Yesterday with a friend of mine I solved the problem of the aircon not working (it's the climatronic panel: it was a for a 2017 car and mine is a 2022 and putting back the factory fitted it works great and now I found a 2022 panel with front and rear heated seats) BUT not the tow bar: looking better, checking with diagnosis we saw the tow bar is present on the car (it's powered) but it doesn't communicate with the rest of the car. Looks like it's connected in a wrong way but we didn't understand where!

Does it have to be connect on the BCM or on the CAN? and at which pins?

@Cairus @mr25 @East_Yorkshire_Retrofits can You help me?

Is it a OEM?

If it’s the Skoda factory electric swivelling towbar, which it sounds like from your description. Are you able to check whether the 13 pin wiring socket in the swan neck is working correctly? My understanding was that a specific towing module had to be fitted and coded. Didn’t you mention this on a previous post - having the wrong one?

Yes, I bought the 57A092160N kit

When I ordered the kit from Carsystem, he included as Control unit the one with part number 5H2907383B —> according to the Skoda Service that installed the kit this Control Unit is specific for Electric cars (Elrpq, Enyaq etc.). Investingatong on ETKA the one I need is the 5H2907383C, so I found one from a totaled car and Service told me the tow icon on the switch that goes in the trunk (once they connected) enlightened but hook didn’t move from its place.

Yesterday, with the friend (with whom I restored the aircon) we saw the tow in the list but when trying to access to upload the correct dataset we got a message reporting wrong connection. We inverted the 1st and 4th pins on the third connector of the control unit but nothing changed, so now (after restoring the pins said above) I believe the problem is in the connection on the front

Module requires parameterisation & coding

Vehicle needs configuration to suit the towbar install

Wiring is all done at the BCM on your car, aside from the ground in the luggage area

I know but if I cannot access to the module, how can I upload the correct dataset in the module itself? Once the module is visible on the installation list I should see as RED but at least I can access to it, am I wrong?

So it doesn't communicate? Or it does?

Can wiring is at the BCM
Power from the fusebox
Ground in the luggage compartment

It powers but it does NOT communicate at all! Are there specific pins where connect the module?

However the connector I’m talking about is the one circled

The data set has nothing to do with basic communication.

Where have you connected the canbus?
Where have you connected the power?
Where have you connected the ground?

I'm referring to connecting to the car not the control module
