Yep in the uk. I'm planning to do just that, however I'm waiting to see what the dealer tells me once they get a reply from Mercedes. I actually have a very good relationship with my dealer (mertrux derby) and I know they are doing as much as they can. So the last thing I want to do it direct a complaint to them.
Totally understand and a very good idea to keep your dealer on-side, especially as they may well be fitting your new roof!!
My issue is with Mercedes. Not the dealer. But unfortunately every single complaint regardless of whether its a customer service issue or build quality issue, it all goes back to the dealer. Which In this case, I think is pretty unfair.
Ill definitely be calling the complaints department at some point and I'll keep you posted.
This is the 100% the nub of the whole issue as far as I can see, you have nailed it!...the UK dealer network has patchy service when talking specifically about the MP roof, some are excellent, others less so.
Personally, I had an MB dealer refuse to do the work full stop, even though it had been pre-authorised by MBUK.
And in speaking to other owners they have varying responses, from being told they need to shoulder a percentage of the replacement costs to outright refusals of acceptance for vehicles still within dealer warranty!
You absolutely hit the nail 100% on the head when you point out that the decision and authorisation sits with MBUK but in order to get to them you have to pass the centralised Customer Services hurdle, which by it's very nature means that you have to be unhappy with the response of your dealer (otherwise you would be happy and have a new roof!)...this route is effectively escalating the issue out of your dealers hands.
I think if you make your dealer complicit in your actions, tell them what you are doing they will accept that and may even be supportive (mine did) and so far in my experience when your case hits MBUK it is much easier to communicate and discuss.
I genuinely still feel that MBUK are supportive of this issue (even for vehicles beyond their warranty period), they do want to help but it does take a little leg work and patience to navigate the procedures.
*My extended reply to you Vandolfthegrey simply for any others stumbling onto this thread in the future...it is clear to me you have the issue well under control. Keep us all in the loop!
