So all you needed to do was swap the 2 pins like I stated or was it something else

M.G.H

Yes, just swapped it at the 330r and the 1.5k resistors. Thanks again for your help!

Some models already have the wires pre installed on them. You just need coding.

if doing the M5 steering you need to work on steering wheel harness.

Hello everyone,

I've added a $2TB VO to a 2008 E61 530Xi and disabled the paddles, then I need to use winkfp to flash the 7601458 or some other ZB number? Thanks

seanjordan20

Yes. Find that ZB-Number and flash VIN.

Thank's

MY GKE215 ZUB Number 7603458 , I can't find $2TB ZUB firmware for GKE215,

Where can find this ?

May some one can reply in here , thanks.

Looks like I may have messed up something with this retrofit. Car runs fine and everything works as it should with the new SAT shifter and paddle shifters and with the instrument cluster. But I have a new problem now that I never have seen it before in my 8 years of owning this E61, that is overheating message in idrive. Driving on freeway seems to be fine, but as soon as I get into atop and go traffic, it shows up. I have to run it by running the climate control at max heat and max fan speed to keep the temps low around 80 during freeway and around 94 in stop and go.

All the programming went without errors while retrofitting.
1) Updated VO by removing 205 and adding 2TB to both CAS and LMA
2) Updated ZUSB firmware to the one ending with 7601458 from existing 7601460 -> Winkfp GKE215
3) Default coded KOMBI, KGM and EGS for stiffness and paddle shifters

Checked waterpump by turning it on via the 10s pedal method and it runs fine.

The odd behavior I did notice afer this retrofit is that the cooling fan turns on and off randomly at full speed even when you start the engine in the morning. How can one check if the thermostat is fine???

Let me know if you need any details inorder to diagnose this issue. I am regretting this retrofit for now and am really leaning to switch it back as I saved all the files before updating in NCSexpert

What could have possibly gone wrong, even when the fan turns ON at engine warm temps, it just turns on only breifly and that too not at full speed while the temps keep climbing. Somewhere it is not reading something properly is my guess. Last time when I ran, I had INPA live watcihng temps and the coolng fan never tried to lower the temps as it kept climbing until I turn on the climate control at max heat to cool down the engine.

OR is it just a conincidence that it needs a waterpump and thermostat replacement?

Is there a way to monitor the thermostat oepning, waterpump triggering and cooling fan triggering on INPA? Would be nice to have a way to monitor when and how they are turning ON and so on

The fan kicking in is telling you something isn't working. Thermostat sticks open when bad so that's not the issue but if you have to open the system up for anything it's best you change it then. Do you not have any errors. Usually it's the coolant sensor that's not working in this case. You should be able to see if the pump is being activated or not. Ohm out the sensor that sits on the radiator to see if it's good or not if you don't have a code. Your symptom is a classic fan issue. Not turning on when it needs to at the speed it needs to be.

Looking at the codes, I have 2E81 code which seems to be related to waterpump. But then it is kicking in when test is initiated.

Thinking of testing the temp sensor, thermostat for proper functioning. Any tips on how to perform this test using software?
