Trailer Assist VCDS/OBD 11 - Camera Obstructed

[phonebooth]

Hi everyone

I had a VW genuine tow ball and module installed late last year. I activated trailer assist shortly after having it installed but didn't get an opportunity to test it until now.

When I connect a trailer to the car and select the reverse gear I'm prompted to select park assist to engage the trailer assist functionality. When I press the park assist button I see the control instructions on my AID only briefly followed by an error saying "Steering intervention stopped - camera obstructed".

I followed the below instructions.

Enable Trailer Assist
Enables ‘Trailer Assist’ option under the headunit settings.


Select Park Assist Module (76)
Coding
Byte 0, Tick Bit 3


Select Instruments Module
Coding
Byte 12, Tick Bit 5


Select Reversing Camera Module
Coding
Byte 10, Tick Bit 3

I had a search of the forum and saw some other members who had the same issue but there's no mention of their fix, if the issue was ever fixed.

For those of you with a Mk2 Tiguan, have you had any success activating trailer assist?

phonebooth : Hi

hmm........ I'm guessing of course, but I suspect that in addition to the changes that you have already made, you need to tell the MIB (the module @ address hex5F) to start operating the trailer-assist function (which is disabled as the default factory setting):

Maybe try this on the hex5F module:

• ENG122227-ENG122319-Car_Function_Adaptations_Gen2-menu_display_trailer_assistant_after_disclaimer > active
• ENG122227-ENG122317-Car_Function_Adaptations_Gen2-menu_display_trailer_assistant_over_threshold_high > active
• * (see note below) ENG122227-ENG122315-Car_Function_Adaptations_Gen2menu_display_trailer_ assistant > active

* = I'm not certain about this channel - try without this change first and add later if needed

I've included the channel names as identified by VCDS - if you use OBDeleven, ignore the leading "Tag numbers"

Hi DV52

Thanks so much for your response. I've seen these adaption channels mentioned elsewhere but some others have mentioned they don't require activation.

I'll attempt to activate these tonight then I'll report back.

I tried last night then forgot to update this thread.

Unfortunately, no luck. Those three options still result in the camera obstructed error.

Something to note:

When selecting trailer assist I receive the camera obstructed error followed by “Rear traffic alert unavailable”. If I don’t select trailer assist while in reverse I don’t receive that alert.
