Disconneting Electrical Connectors- HELP
 

Trying to replace the coolant reservoir on my 2008 S6, and cannot figure out the secret to releasing the electrical connectors on the mass flow sensor and the bottom of the bottle, it must be simple, however I'm missing it.......tired of breaking connectors so asking for the secret. Thanks!

Maybe this will help. Haven't bought it yet but I plan on it.

Figured it out, had to walk away from it for a few minutes, you just have to pull backwards on the tab that extends out from the body, this will release the connector from the catch, wasn't obvious to me........got the reservoir replaced, picked up from Genuine Audi Parts for $27, Dealer wanted $90. Managed not to break the Y pipe. All good now!
