What manual is this? I'm still looking for a good one.

DrDoe

WISEPC for 2015. If you go back to my filter and dealer thread you can down load it. I can walk you through if you have issues.

Jack_88

Much appreciated.

This may take a while.

ssfisher

Yea ill swap those today and report back later. Thanks!! Havent tried this yet. Would the nr. Numbers on the climate control head help? The "hidden diagnostics " nubers. I can warm up the car to operating temp and write those down if it will help. Thanks again, ill report back after i swap 18 and 19

DrDoe

Don't mention it. We are here to learn and to share right?
#1 to #9 are what you need for the database. The rest are just trash.

DrDoe

They might. I don't know the reference values but I can compare yours to my readings on the 04 S430

ssfisher

Roger that. Ill get 1 and 9. Im learning everyday with this car. I enjoy it tho. Those sensors look like they are behind the radio and climate controls. Is that right?

DrDoe

Yes. They are. I think you need to start at the ashtray then go up to the radio.
After I got my 1st S, I always wonder if I should go with the newer E. Well, I got my answer this week. I still like my older S more than this newer E.

ssfisher

Nice. Ive got the radio and climate controls and ashtray out. I think i see the sensors behind some gray insulation. Trying to remove plugs now

ssfisher

Ok, swapped wires from left to right. They are two wire plugs. Small. I think those are sensors? Nothing changed. Still heat on drivers side cold on passenger and same 1417 code. Also reset code, no change. Here are some numbers while at idle:
Nr.00 +20,9 Nr.06 +75
01 +22,5 07 12,2 bar
02 +37 08 +40,7
03 +11 09 +9.8k
04 +45 10 5,8v
05 +4,4

DrDoe

That's disappointing.

My 04 S430
Nr.00 +22 Nr.06 +80
01 +22,5 07 12,2 bar
02 +35 08 +41
03 +7 09 +8k
04 +4 10 3,0v
05 +4

Is 04 a typo 4.5 and not 45?

ssfisher

I just started car and at idle: nr.04 +51c

ssfisher

In going to put the plugs back in the original sensors and check numbers again

DrDoe

04 is on passenger side?
Perhaps we haven't swapped the sensors yet as they placed after the plugs #18 and #19?

ssfisher

Plugs in original positions:
Nr.00 + 22,6c
Nr.01 +24,7c
Nr.02 +44c
Nr.03 +49c
Nr.04 +15c
Nr.05 +5,3c
Nr.06 +81c
Nr.07 13,3 bar
Nr.08 +44,2c
Nr.09 +9,3k
Nr.10 5,8v

DrDoe

Make sense. 03 is on driver side

ssfisher

So here it is:
Plugs swapped;
Nr.03 +14c
Nr.04 +51c

Plugs in original position;
Nr.03 +49c
Nr.04 +15c


With this info i would say sensors are working like they should. They are reading acual air temp

ssfisher

Do you know what should happen if i unplug the dualvalve solinoids? The two small solenoids. I think the larger one is the resurculating pump? Will doing that tell us anything? And thanks for you time. Im sure you have better things to do on sunday.

DrDoe

Sorry I went off the grid. I haven't run into the duo but here is its function

DrDoe

I still think this is the sensor issue. Here is the function and the location.
On a separate note, I found the sensor location for my rear unit. Haha!

kraut56

My $ 0.02 worth:

as mentioned before: check the voltage at the duo-valve solenoids, must be the same for both under same selections on control panel.

IF we are talking about cars with the REAR ac, note that the (separate) duo-valve for that one is in the right forward fender (incorrectly described in the WIS).

DrDoe

Unless I'm mistaken, he replaced the duovalve already from earlier post

kraut56

yes, but in this whole saga he has NOT confirmed that both solenoids actually work.

A used unit could be just as bad, as these duo-valve are notorious to stick.

Proper trouble shooting is advised here, before going into sensors.

The solenoids can be removed to check for corrosion at the springs, and the solenoid plugs can be disconnected/connected to test for function, after verifying voltage at the plugs.

DrDoe

I see
