thanks. We added the wire from T15/1 to the cluster T32 connector. When I get the low level warning light it won't disappear unless you recode the cluster. IT's a PITA to drag out the laptop when the oil level drops below the range of the dipstick!The bonnet switch is a direct connection to the cluster for the oil sensor reset (and "bonnet open" warning).
On the OEM setup there is the wire to the bonnet switch and it just T's off into both the CCM for the alarm and to the cluster for the bonnet warning light.
So they seem to be mutually exclusive.
I had the OEM alarm fitted with bonnet monitoring and only had a wire from switch to CCM
When I fitted FIS I did not have the bonnet warning part active.
So the FIS did not pick up any canbus signal or anything from the CCM to say the bonnet was open (like it can do with the hatch warning)
I had to splice a connection from the existing wire to get the bonnet warning.
I would say the CCM coding to enable the bonnet switch is purely for the alarm monitoring.
There may be a cluster issue if you have a US cluster - some posts on this page talk about the cluster EEPROM coding:
If you have the warning now though, that is probably okay in your car - it's just the reset that is the problem for some reason.
As per the SSP .pdf once bonnet opens the warning should reset and if level is still low it should come on again after 100km
If you added the wire after the warning was active already, maybe just re-enter the softcode to not have the warning and then recode it again some time later to enable it again.
Unless you can think of anything else (like the level is actually too low!)
I believe I still have T15/1 connected to the cluster but I don't think it does anything.
