Sedici rough idle error code

Sounds like a classic motor mount issue! The error code definitely points in that direction, and the uneven idling is a tell-tale sign. I'd start by visually inspecting the engine mounts themselves – look for any cracks, tears, or excessive play. Especially check the rubber mounts; they tend to degrade over time. Before you go too deep, have you checked the wiring and connections to the engine mount? A loose or corroded connection can throw off the sensor and cause those symptoms.

Thanks! Where exactly are the engine mounts located? I'm not super familiar with car mechanics, so any guidance on where to look would be appreciated.

Okay, so on the Sedici, you'll typically find engine mounts supporting the engine block. Usually, there's one on each side, and sometimes one at the front or rear. Since you've already got the error code and the rough idle, and you're not too familiar with the layout, honestly, I'd suggest taking it to a workshop. If it's just a loose connection, it might be a cheap fix. But if the mount itself is shot, replacing it can be tricky and you'll need the right tools. Could save you a load of frustration!

Appreciate the advice! Took it to the shop, and you were spot on. Turns out it was a defective engine mount, likely a damaged connection like we suspected. Cost me 95€ to fix. Runs like a charm now!
