Greetings!

Can anyone please help me with a Relay map/meaning for a Stilo JTD MW 115HP 2003.

I can't find it anywhere.
Every two weeks my JTD won't start until I remove and plug again some of the relays.

If I know which one is the problem and what it does perhaps I can swap it for a new one.

I found out that some of the relays had a bit of green oxidation on them.
I used a metal brush to clean it out, but now it happen again.

Cheers

does this help? it tells you which relay in the engine fuse box (T#) and shows a little picture of what it controls. im pretty sure the fusebox casing has T1, T2, T3, etc printed on it

There is a good pic of engine bay fuse/relay board in post 4 in the link below,
Also if you have a cover for you battery which is very worthwhile having to stop water damage to the fuse/relay board, there are details of the relays on the underside of the battery cover. a fault code reader is also handy to have and any error codes it may have to find the item at fault.

Being a jtd and having problems starting it may be the relay to the fuel pump,so long as it is not the fuel pump sticking or another item not related, I had problem once with relay for fuel pump T10 in the past and swapped it with the air con compressor relay T5 until I got a new relay,, any ways image in the link below post number 4
