Stop-start delete

Post by corrigan42 »

I have a 2019 Caddy and would like to get rid of the annoying stop-start feature!
Is it as simple as plugging one the things I see on eBay / ali express to delete it? Or is some coding required?

I managed to code it on my a6 that the start stop button remembered the last known state, and also reversed the light… so light on means stop start is on.

Would love to know if this can be done on the caddy as well!

I love start stop, I replaced my battery with a new one just to get it working as mine had never worked.

I've never seen an obvious coding option in any software for that, and I have them all. VCDS, Obdeleven etc. However there will be people with tools which can defeat it by setting a condition to prevent it coming on.

One possibility is putting a switch inline with the thin wire coming off the battery monitor which is built into the negative terminal, preventing monitoring of the battery voltage. That will prevent stop start from being available.

It will also put your alternator onto full output mode too instead of smart-charge. So it would then charge a leisure battery mounted inside.

Should be no engine management light from that and you could easily switch it back on anytime you liked.

Caddy ECU and BCM are a bit hobbled compared to the car versions, with much less options available to code in or out. Even the highline van version has the most options but far less than for example a Golf or Passat.

You can also disable it in VCDS giving start stop some high temperature set point for it to work. (or not to work 8) )

Really interested in this possibility - I don't suppose you remember which module this is in, etc.?

Thanks

Not really, I was messing around VCDS. Probably in engine section. But this was in coding section. Hope this narrows its down

You need to give it impossible to reach conditions to activate

I also love start-stop. I don't understand why people find it annoying and delete it. Something that saves fuel and reduces emissions, and a nice peaceful moment at every stop light? Nice one :D
