I have a 2006 CLS500 and I had to change the ECU for the airmatic system (I used ECU part number A 035 545 32 32) and now my seat heat and cool is no longer working. Could the two be related? Any ideas on where to start to troubleshoot the problem?

Thanks in advance,

No -----you have what is called sympathetic psychosis(when you FU you blame something else) ---------post the VIN!!

Plutoe thanks for the diagnosis lol but I didn't actually do the work or change the part but I do wanna blame somebody! Here's the VIN

Regrettably I don't think that you can blame anyone, except yourself for reporting a non existent part number. 035 545 32 32 does not exist,however 037 545 12 32 replaces 036 545 32 32---do you know what you purchased!!

In any event they are not electrically connected. Your SA code 401 shows that you have front R and L HS/vent seats----and the system is networked as follows--upper control switch---upper control module--D side HS/Vent seat control unit-R and L blower regulator---the same network is also used for the heating function, except for the blowers.

Now you ask what is faulty--I haven't got the foggiest F idea until I plug in my DAS Xentry and interrogate the system.

I believe the only thing you can do is make sure all the connectors are intact on the underside of the drivers seat control module and look at all the fuse's
