you're actually posting onto a site where you're unlikely to get much help with your problem.You're on the wrong part of the site.
If you look to the left of the list of car-specific sub-folders on the home page, you'll see that this particular thread is for the Ritmo/Strada from 1978-1988 only.
You say you have a 2008 Ritmo, i.e. do you have the later incarnation- the pickup, the European later car- which has never been retailed in the UK..As you're in Denmark,(despite the Aussie flag)perhaps that what you have?Or,have you the Australian car, as suggested by "Portland Bill" above, known in the UK as the "Bravo"?
The model "Ritmo" has never been a UK name. Only (European name) Ritmos from 78/88 were retailed in the UK,always as "Stradas". This has caused huge confusion- I had great difficulty French registering my 87 model, only because it was called "Strada" rather than "Ritmo"
Your particular vehicle ( if the pickup) is- strangely- also retailed in Italy?Spain etc as "Strada"!!!
There will almost certainly be common parts from your 2008 car with other current/recent FIAT models.
I suggest that, if you place further posts, you do so in the "technical" section, rather than the "Strada" section- explaining just what you have and what you know of common FIAT parts- then you might get assistance from owners of newer cars cars with possibly common issues
Good luck
