Yeah I'm getting fed up with it.

Unfortunately the cheaper part is in Poland. And don't want the jeep running about in limp mode and constantly clearing codes for it to run so going to have to bite the bullet and get the module from a stealership.
Chrysler/jeep have one in stock in Cardiff Mercedes near me have a few on the shelf so I'll pop up there later.

Rang a breakers and they want £110 ish for a second hand unit but they are sealed so not going to risk it.

Bloody cars! Cheaper than cossie ownership no doubt haha.
