Whilst we are waiting for casper1986 to come back to us I would like to get on my soap box!
Fiat Dealers and their Fiat UK support structure are supposed to be able to sort parts issues like this out. It doesn't matter if the part is worth 5 pence or £5000 pounds.
It is down to everyone of us to hound and hassle dealers who can't provide what is a fundamental service.
Car chassis number, spares number etc. should and in most cases will deliver a correct part. If ordered through a dealer and that part is wrong then the dealer will/should absorb the cost and get back to Fiat UK Parts Technical to resolve the problem.
THIS IS ONE REASON WHY YOU SHOULD NEVER QUOTE OR ORDER BY PART NUMBER from a Fiat or other dealer. Quoting a part number forms the basis of an order/contract and if the part number is wrong then YOU are liable, not the dealer/supplier.
HOWEVER if you clearly give the dealer your vehicles data and state the part you require then it is their and Fiat UK's responsibility to quote and deliver the correct part.
Whilst I will happily help people with part numbers etc. it is NOT my preferred option. DEALER 1st, 2nd, 3rd .... times always.
ONLY authorised dealers have the fully up-to-date information at their disposal.
My only deviation from the above statements are for older cars like the Strada 130TC and any other car model who's parts Microfiche slides were never integrated into
ePER. Besides not being in
ePER most parts are long discontinued. Also most if not all current Fiat dealers no longer have the parts slides and equipment to look up said parts and can only revert back to Fiat Parts Technical. (only to find the part is no longer available etc. etc.)
If your local Fiat dealer can't/won't take the time and effort to "service you" then get straight onto Fiat UK/Italy customer service and rattle their cage.
If I/we/others can take the unpaid time and effort to try and identify a part then I expect a franchised dealer to do better and if they can't then they need "chopping" immediately.
