I have a 2012 Audi Q7. The AC (air conditioner) does not cool so well. The air from the vents is not forceful enough, and of late I have noticed that the right-hand side vents blow warm air. The only error code I have is for the air quality sensor, which I presume is bad. I have performed the actuation test and the only component with a negative result is the fresh air blower. This is replicated in the measured blocks:
09:15:24 Group 045: Fresh Air Blower (V2) - LIN Bus I
1.0 Fresh Air Blower Voltage (act.)
11.00 V Fresh Air Blower Voltage (spec.)
75.5 % Fresh Air Blower Activation
Faulty Fresh Air Blower Feedback voltage/load
I observe that the first column remains at 1.0 volt no matter the fan speed. Is this normal? The second column varies with fan speed. The last column clearly indicates a fault. What is the nature of this fault? Any relation to the reading in the first column? Does this have any connection with the under-performance of the AC system? Again, is the fresh air blower control unit (J126) a probable culprit for the faulty readings from the fan?
Thanks guys.

Hello! I have a cable that i bought in my country. I can read the failure code but i need a registration software of ross tech to clean the memory. Anyone have this program full?
Maybe someone can help me. I try to read out a C-Class (W204) and getting this communication error.
My KTS 540 is being recognized by Xentry at startup, but I cannot read out the vehicle.
I get a communication error and a message underneath:
Hinweise für den Support com.teradyne.ds.gradex.asam3d.Asam3dApplicationException: Error details: MCDError: <Undefined> (0xe512) VendorCode: [0] at intern/CheckVCIConnection/intern/GetBatteryVoltage_IgnoreError/NODE5 in file:/C:/Program%20Files%20(x86)/Mercedes-Benz/Xentry/Kontexte/Allgemeine_Ablaeufe/Fahrzeug-Kommunikation/Asam.gmf
Maybe someone had similar issue and can help with a solution.

I've just done my first ever read of my ecu on my 2009 E61 535d.I've had my ori file modified and got a 3 options to flash back on.
If you could review the tuned files that would be great, I'm not sure which one to use. I'm looking for stage 1 with DPF & EGR off. minimal smoke and being able to keep my dpf sensors plugged in.

Is it necessary to disconnect the front and rear batteries on the s206?
There is a battery on the left front under the hood and one in the trunk on the left side if you are standing from the back?
Or is it only necessary to disconnect the front battery to do work on the car?
