Relay locations

[bigwinn]

Afternoon all

I need to check my relays (not the ones in the engine bay)

I can see a cluster of 5 or 6 behind the fuses in the passenger footwell (near the GM5 module) but I am not clear where the others are- do I need to disassemble the glovebox?

Cheers

I think that's all there is.

I thought there were 3 locations for relays-

1) engine
2) the ones I can see near GM5
3) ??

I’d seen that before- still can’t figure it

If I’m reading this

Passenger side behind glovebox?
Then it goes a bit hazy- hence me asking if I need to strip the glovebox out more?

I’ve not got my e85 anymore but i seem to remember there were more gubbins behind the fuse box?

Here is where i'm lost a bit

scroll down; there are 3 relay locations

two are 'glovebox area' and the other is engine bay

Found them!

Behind the fuse panel, up by the GM5 module

Now according to this I am missing a relay- I think, as referenced by Rob above as the K6304a

BUT

Should my car have that relay- would it be fitted with a secondary air pump?

I know I'm shooting in the dark but I am just trying to find the root issue with my aircon issue

Thanks again for your help. I need to investigate further, now I know where the relays are located.
It's been a saga, but my son's car refuses to start, having replaced the starter motor. At least is does now turn over/crank!
I suspect it may be the crank sensor at fault... If so, would this result in no fuel being pumped, and/or no spark at plugs?

I’d imagine so

I’ve not had anything to do with CPS on z4- only m20 engine on an e30

It had worn as it was rubbing on a pulley

Worth a check but I guess it would stop ignition
