Hi. Brand new to this site. Bought a black 1.6 diesel Delta Momo Design a couple of weeks ago. The previous owner switched external badges to Lancia. Other than that, the car is de-badged, i.e. the Delta S sticker has been removed. Loving the car and how it looks. Two things I could do with some advice on: one is a knocking sound on start up. I've read that's normal. Any thoughts? The other is the SD. Sat nav thinks I'm in Yorkshire and just can't seem to put it right. Don't really want yo plug my portable satnav in.
