750il V12 M73 Evap purge vavle

[Hesten]

Looking for help from any of the V12 gurus on the forum. I got a code for a bad evap valve and I can't find the location of the Evap purge valve in the M73 engine.

Thanks for your help!

It's the pair of loud clicking mechanisms next to the oil filter. One for each bank.

Thanks! I circled them in white. Are those it?

I had read reports on how to change them in the V8s and this is much better!!!E38 M73 Engine.jpg

Usually referred to as Tank Vent Valves. If the labels to their connectors are still present, they state which bank they are for, as each is controlled by its DME. Worth checking the connectors haven't been interchanged.

Thanks for the help. Yes, there are labels still on the connecting wires. Thanks guys! Not a lot of literature online for the M73s. Thanks!

Funny but I had to replace both of those puppies, one after another in the span of few hundred miles.
