Subaru dealership "cannot communicate with my car's ECU"
3 weeks ago I took my car in for service at my local service place to fix a check engine light issue. I already connected to my vehicles computer via OBD and my app Carista and the code was an A.C. code (sunload visor). I don’t have a clue about how to fix it.
Background: My vehicle is modified with a Supercharger, custom exhaust system, custom tune, and Flex fuel kit, and nothing else. Nothing that should prevent them from fixing the problem.
The local service place tried multiple times to fix it, they bought multiple A.C. sensors from Subaru but they both failed to fix the issue, they recommend I take it over to the dealership so they can fix it.
OK So 2 weeks I took the vehicle over to my local Subaru dealership. After running diagnostics multiple times and multiple ways they told me their computers “cannot communicate” with my car’s ECU. They have never seen it before. They said it could be due to one of my aftermarket parts, and that the way Subaru’s computer’s cannot read my vehicle. I told them ‘are you kidding me’ I just connected to it using a $50 OBD app’. They said theirs is different and if a vehicle has any aftermarket parts, it won’t read the ECU. They recommended I remove my supercharger and I then proceeded to laugh at them.
So now how do I fix the problem? They wouldn’t know, and couldn’t tell me.
Fast forward last week, I parked my vehicle in a parking garage and they lost my keyfob. Luckily I was able to Uber home to get my backup one. I purchased a new keyfob from Subaru. Today, they had to re-program my new keyfob. And the same exact issue cropped up. They cannot communicate with my vehicles ECU. They don’t know what to do. If I lose my backup keyfob, I am screwed here.
So has anyone else had this problem before? I have previously taken my vehicle to this dealership many times over the years for general service without any issues until now. All of a sudden their new Subaru “supercomputer” cannot connect to my vehicle just because I have a few aftermarket parts in it. It’s absurd.
Meanwhile I still have my check engine light on due to the AC sensor (sunload visor), and I cannot get my keyfob reprogrammed because they cannot communicate with my ECU.
What do I do here? Any advice please, I am stuck here. Maybe there is something wrong somewhere in my vehicle and that's the issue but I don't know what.
