Hi

just looking into how the alternator/generator on my 09 TDI and related VWs work, and can be monitored in VCDS

I know you can monitor the voltage,

and the generator load, which reads the output from the alternator regulator.

is there a reading for commanded input to the alternator?

if not, is there an test to turn the alternator on and off? (similar to the fuel pump)

( I think a year or so ago I was looking for a reading of fuel lift pump control, and figured out it is always on when the engine is running, but you can use the vcds to turn it on when the engine is not running)





thanks.

Mike

Mike,

It very much depends on the actual model if there are advanced diagnostic possibilities or not. For example current models with start/stop use an intelligent generator which is actually connected to the cars databus system. On gasoline engines from ~2000 up you will often see specific measuring values (MVB 050-058) which have some relation and allow for some reasonable diagnostics.

Now as for your TDI, since I am not exactly sure which engine you have and what other stuff is installed - please post an Auto-Scan from the car in question so we can have a closer look.

Hi,

About all you can do is view the load value of the Generator.

Have a look at Measuring Value Block Group - [016]

- Field 1 = Generator Load Normal Range = [0.0...100.0%]

Hope this helps,

dpeter

Thanks.

guess you cannot have everything.

do you think there is a way to display measuring block 016 field 1 on a ScanGaugeII?

(I understand this may be the wrong place to ask)

Are you wanting to display volts or amps?

Maybe a nice digital combination Volt/Amp meter will work for you?

You will only be able to display ECM data if the device can communicate over the OBD-II Connector.

In addition to the VCDS, which I use with my laptop, I have a scangaugeII which sits low on the dashboard, and plugs into the OBD, and which can display four digital readings. I have an Exhaust temp, which lets me see the elevated temps during DPF regen, as well as volts and coolant temp. the alternator/generator load would be a nice addition.

The VCDS includes the ability to send commands, and format replies. commands/requests can be specified as a 12 digit hex string (appends 0 as needed). (with other inputs to the scangauge to specify reply, which parameters to display, and what to call them

I will ask a few other places for specific help, but do you know what string the VCDS sends to read engine block 16?

Thanks

I will ask a few other places for specific help, but do you know what string the VCDS sends to read engine block 16?
The request "string" itself won't help you if the device in question isn't communicating with the car using a protocol under which that string is valid. VCDS reads Measuring Blocks using VW's proprietary protocol. ScanGauge does what it does using the generic OBD-II protocols. A request from one doesn't translate into the other.

so it sounds like the modules respond to multiple protocols, in some cases. (like those I referenced earlier)

that makes sense, since the mandatory responses for emissions need to be per published standard

does the CAN gateway translate proprietary protocol info to CANSF?

is there a way to update the gateway to add additional readings?

The gateway is like a router than a protocol converter; it just shuffles traffic between the different CAN buses.

So I have a follow on question. Thought I would put it here so you can reference the auto-scan from my car.

I see several places in the engine control screens to see and log coolant G62 values, (on the engine near coolant outlet) but wonder where you suggest I can look for G83 values (near radiator coolant outlet).

Is there a good way to search for specific sensors using the VCDS?

well, that did not work. nothing but blanks for Block 130.


perhaps I just do not have the G83 readings available.

No, there is no search means within VCDS. Did you try using the Advanced Measuring values? If these are available for your engine controller, the block/value names are given in a drop down list. That list can be of help in finding the parameters one might want to view.

Thanks, Bruce,

I did find the advance measuring values screen, and it is a very handy tool, but find it filled with half a dozen copies of the G62 coolant temperature, but no G83. Guess some VW engineer did not want to confuse me with two coolant sensors.

There are coolant temp readings on the HVAC controller, which do not have sensor identification, but I suspect they are really r134a temps.
