Welcome.
This is Landyzone, the best
community for Land Rover owners on the web.
As a community, we have the Introduce Yourself section, so that new members, like yourself, can post a little about themselves and their vehicle, if they have one . Thus building on the
community spirit of the site
Which is nice. Rather than a smash and grab approach, wanting help on a first post. Especially, when asking for free help, from strangers, who are not paid to, and do not need to, help you.

Perhaps do a little reading of the thousands of posts, already on the site, about this subject. Then come back with a less generic demand for advice.
Again, welcome
Oh and this is where you will find the thousands of posts on Discos
