I too am experiencing difficulties in sourcing a tow bar for my 2018 ST Line. I want to tow a Trailer tent....
I have visited 2 dealers local to me (Staffordshire) and both told me there aren't any available anywhere. The Bay of E could be a route to purchase one and for one of those dealers to fit but this doesn't sit well with me as regards to guarantees/warranty etc.
The dealer I spoke with today told me that it's also vital to get a dedicated electrical tow bar kit for the car rather than just to tap into the existing wiring loom. These kits are warranty protected and are the better option.
But of course, like everything else EcoSport Accessory wise, sourcing a pack is feeling nigh on impossible.
Both dealers agreed the best version to have would be the detachable 'swan neck' version so as not to disrupt the rear parking sensors.
Thanks,
B
