Hello all, and merry christmas.

Trying to get my head round the 16v fuel quality relay. I apologise for my ignorance.

Could someone explain to me what each of the relays in the pictures are - and if it looks correct. Im assuming i have the yellow (95 ron with cat) relay? I have no idea which ones connector s30. It looks like a different setup to every picture i have found!

The car is a 1993 16v with cat.

I use 98 ron, but i'm assuming the 16v doesn't have a knock sensor? so will this make any difference at all?

Thanks - im getting there haha

Hi,

That all looks fine Adam.

My car is a '93 catted 16v too. I'll try and get out to confirm later and take a picture.

From memory the yellow one is the fuel pump relay and the red stripe one is ignition relay.

Cheers,

John

Ok here are mine.

I replaced the fuel and ignition relays a few years ago as they packed up together for some reason- they are just basic relays- don't think they are anything to do with fuel quality- might be wrong. Mine were originally like yours- 1 mustard colour and one red stripe.

I've never touched the other group of relays shown- these are how mine have been since 2001 and probably since the car was made.

Hope that helps!

John

Hi

beware, Bosch relays with a red stripe on the metal housing (like the one on your first picture) are diode-protected and shall be replaced with a similar item

Ah thanks,

That thread with JeremyC is the same car! I bought it from him back in April.

There is no sign of that orange plug. (see top pic) Bit confusing - although it does look the same as john 33's set up.

Does not having this plug mean I should be running 98? or is it just hidden somewhere else?

I wouldn't worry too much about it Adam. Are you having any running issues?

The fuel pump relay in mine now is a genuine bosch part 0332 014 112 and I assume it's diode protected from the diagram on the side. It came like that -plastic/ no red stripe in 2012.

The ignition relay (the black one) is a generic ebay part. I couldn't get the original Italian made mustard colour one with the orange base anywhere.
