Hi Guys , I'm looking for information on how to adjust the internal voltage regulator on a 2009 passat with a valeo 180amp alternator. I've found plenty information on other branded alternators but hardly anything on valeo ,Or i would even appreciate information on how this specific alternator adjusts the voltage so I can manipulate the readings it gets.

Welcome to the new look VWWatercooled
After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.
Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

Hi and welcome
Being a 2009 I think that was right on the cutover with the DFM and LIN alternators, in your installation list do you have "Address 61: Battery Regul. (J840)" ?
If it is the LIN version, the brands have a standard coms protocol.MY12 Passat FSI Highline | 3.6L VR6 | Cashmere Brown | Driver Assistance Package | Dynaudio | Discover Media | TPMS Direct | Side Assist | Adaptive Cruise | 3D colour cluster | More coming soon

Thanx for the welcome Mate .. but Nah not LIN , it's DFM and L . There must be a way to internally manipulate the regulator... but I've been searching for days and haven't found solid info. Plenty on Bosch and Denso , But almost nothing on Valeo.Last edited by Vinny187; 18-11-2024, 06:44 PM.Comment

Are you trying to increase the voltage at idle or something? or is it not outputting the correct voltage?
As it's an internally regulated alternator, you can sometimes open it and get to the connection used by the regulator reference. Adding a diode between these will cause a voltage drop to the regulator, making it output more to compensate.MY12 Passat FSI Highline | 3.6L VR6 | Cashmere Brown | Driver Assistance Package | Dynaudio | Discover Media | TPMS Direct | Side Assist | Adaptive Cruise | 3D colour cluster | More coming soon
