[MAK_US1977]

Hi

I have Passat B6 2010 , if the car parked in sun for longtime and car get very hot, when I put remote and start the car , i get message immo active
if i left the car windows open for 15-20 min it start normally

I scanned the car with vcds i get error in immo 3c0959433AR

01176-key
004-No signal/communication

I changed ignition starter switch 3c0905843R and still same problem happens

do you think the central control module for convenience system 3c0959433AR need to be replaced or what?

best regards

I don't know for sure, but they are very cheap to find used, so copy immo data and try.
