What did you do for your ZHP/ BMW / MINI today? #2

[t.er]

As far as I know there is no way to get rid of the readiness monitors of the SAP on MS45. There will always be at least one showing not ready. Same reason why I haven't removed mine either yet.

What's the code? If you can, go grab a salmon relay from the junkyard and replace yours. If you're lucky that will fix it.

2761, secondary air system. Unfortunately that won't work, you can hear the SAP turn on upon cold start. Lately it's been louder than usual so I suspect something is mechanically wrong with it

Connect to a big giant resistor to simulate it accepting power and using it? *

Hahaha. Well if I just need to pass I can drive around, clear the codes, drive around a bit more, and then get smog'd. Just have to make sure coolant temp doesn't go below whatever value it has to be above for the SAP not to turn on.

Well I got all summer to figure it out. Gonna leave it for now since tmrw I have another track day, maybe I can even fix it - there are quite a few threads on E46F showing what others have done

I'd still give it a shot. Mine still turned on during a cold start but replacing the relay still fixed it.

I had the SES light, even after replacing all the crumbling vacuum hoses from the pump & valve back around the head on the 2000 328i. I bought an SAP on eBay for ~$45 that worked fine, but would not stop running! Replaced the salmon relay behind the glove box = the solution Passed Virginia emissions & no SES light.

For sure, will do!

Good to know! I had a quick look on E46F and it seems there were 2 versions of the SAP, and our ZHPs got the later version which has a MAF (jesus christ there's a second MAF just for the SAP?!?! lol) with no vacuum hoses to the intake. My hoses are still pliable and not leaking. I did take off the hose from the pump to the check valve and the check valve is a bit crusty, which kinda looks like what this user saw in his car so I'm thinking it could be seized. I think my plan of action is as follows:

1) Check the pump actually pushes air (which I'm sure it does, since you can hear it, but need to take the hoses and actually look)
2) Check the check valve (haha) isn't seized, by trying to blow through it
3) Diagnose salmon relay with multimetre
4) If the above 3 seem fine then it could be that secondary MAF

God dammit more issues. Halfway through a track day my battery light came on. With the engine running voltage fluctuates mostly between 11.9 and 12.3V, occasionally I see a rise to 13V. Battery light is intermittent.

Reading online it seems I can just replace the voltage regulator, crossing my fingers it's just that.

Well... my OE battery is from 2014, tempting lol. But it's only seen a couple winters and I've read people getting exorbitant amount of time out of theirs.

I'll diagnose my SAP and order whatever parts I need along for that along with the voltage regulator from FCP

Oh and you should get the eKombi you posted about last year... I didn't have a multimeter on hand but I could easily access battery voltage through that. Well, I guess I could've used the cluster menu as well, but still... So nice to have voltage displayed on the drive home
