I bought a Pfaff QE 4.0 in Jan 2013 and had a problem with the lighting. The dealer replaced the machine with a new one from their stock because they know Pfaff takes a long time to replace parts/machines. So I think you need to talk to the dealer and see how they handle returns. If the dealer can't or won't replace it and must wait on Pfaff, that would be something to consider. BTW my new QE 4.0 is perfect and I am a happy camper (sewer)
