Technical Stilo 1.8 disel noise !

[djsjamy]

My 10 years old Stilo started to make disel noise! It's coming from the variator solenoid. When the solenoid is replaced(new) the sound goes away and comes back after 1000-2000km. Found out that the spring in the solenoid gets weak over time and it's not working as it should. Is there any way to change this spring with a new one ? Can only get the solenoid not just the spring! Any one had the same problem ?

Thanks

There's a repair kit available from Fiat consisting of the spring and plastic washer, part number 71715450, about £8 (GBP). I don't know if the kit is for the 1.8 or 2.4 engine, or perhaps it's the same kit for both.

Don't think this is the spring that I am looking for!

It's this spring on the right! It gets weak and the valve is not operating as it should and is hiting the solenoid actuator!
