Exclamation I Need help with a Fault!! stilo 1.2 16v

Hello everyone i'm a new member as of about 10 minutes ago haha, the problem im having is while driving along or stationary there seems to be an intermittent fault where a loud clicking can be heard from the relay in the fuse box next to the steering wheel, when this happens all guages on the cluster drop off to zero and the engine starts to briefly miss. also if the headlights are on they will turn off. i have tried all the earths in the engine bay and still nothing has helped hopefully someone could point me in the right direction, thanks

How did you "try" all the earths in the engine bay?

Check the multi-earth connections on the right of the centre console/tunnel near the ABS ECU, and under the right front wing.

Feel the relays to see which one is clicking.

If the relays going mad pull it out check the pins for corrosion, clean and reinsert.

Likely culprits:

Relay T13 supplies the three door control ECUs and the sunroof (if fitted). It gets an earth via the body computer from the multi-earth point C15. I think that's the one next to the airbag ECU.

Have you checked that one yet, as I suggested above?

yes i have completely cleaned every inch of the fuse box in the engine bay even cleaned every fuse and relay and sealed the whole unit in a case to protect it from any water but its still doing it so the next ones to try are the earths on the tunnel and the one inside the wing

Had exactly the same problem.

Probably you need to replace the temperature sensor housing inside the intake manifold.Check for coolant leak there that makes shorts to cables.

Re: I Need help with a Fault!! stilo 1.2 16v

just to some up this whole thread the problem ended up being a cracked coil pack was earthing off the engine and causing an intermittent power loss problem.

How bastard random is that?

Still... at least you have the beast back... and someone else might have the same problem and might not think we're all mad when we tell them to check the coils..
