Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologise for any delay.
I try to be here most weekdays and some weekends. If you respond and I do not respond back right away I will do so as soon as I can.
Dear customer, if I understand the problem it presents, it is not really very complicated to solve it, because you are presenting a mismatch in the roof, it is very surely in the rail, what happens is that these mismatches may be due to common wear problems, it is normal that happens over time, these rails adjust, they are disassembled and accessed, any Peugeot technician can do this job for you, it is not complicated and it can actually become routine, it is not expensive, you do not have much of to worry about.
The worst case scenario is that the rail needs to be replaced but I do not consider this to be the case as the roof is going down and up normally from what I see and in cases of extreme wear this is not possible.
