2017 AUDI A3 BLOWER MOTOR REPLACEMENT 

I would use a scan tool and see if it’s just something that was set while apart or if something needs to be plugged back in, for the money this one is really excellent amzn.to/4dZAF3C

I just had the exact same thing happen. I am going to order the scanner

I’ve had some Ill fitting aftermarket ones cause noises in the past, make sure it’s mounted properly and if so try to return it

@@EuropeanAutoRepairyeah that might be it, I’ve contacted the seller to see as it might just be an aftermarket thing. It seems fitted well to me but I guess I’ll have I double check that too.
