4-Year-Old C Class Coupe Wiring Failure - Quoted £9,000!

[Dan Tanna]

I have a 2016 C Class Coupe 250D AMG-Line Premium Plus, 30k miles.
My boot stopped opening the other day - wouldn't open at all.
Took it into Mercedes dealership (I have an extended warranty). They came back and said 11 wires on the left and 5 on the right were all broken. Extended warranty doesn't cover this apparently!
Mercedes' recommended fix would be £9,000 to replace the entire wiring loom!
This is clearly not wear-and-tear and points to a more fundamental problem either in design or manufacturing.

The MB dealership offered to fix it the non-Mercedes £9,000 recommended way (which is odd considering they are a MB dealership) and for £1,800 which I declined, obviously.

Can anyone on here offer me any advice? Is this a known problem?
If the Mercedes dealership won't budge, what are my options?

Thank you.

I wouldn't let it drop, keep on at them, ask to see the top man at the dealership, phone Mercedes themselves, I'll bet you will get it sorted, and if by chance they do dig there heels in, and won't budge, take it to a Mercedes indie, or a reputable auto electrician, who I'm pretty sure could fix that, I mean how hard can it be to splice 16 wires together again. As for £9,000 they are obviously having a laugh or smoking wacky backy.

Auto electrician to reconnect all the wires and put some heat shrink tape over them ?
Failing that I might do it for 8k

Thank you for your reply. It's really terrible. The dealership even said this shouldn't happen but they don't appear to want to help or fight my corner.

There's no way I am having it done at Mercedes unless they pay the £9,000!

As I've said, kick up an almighty stink, me thinks, you'll get it done, under your extended warranty.

I'll do it for £7500 ....

There's no way on God's earth, that job is £9,000.

The whole of WW2 cost less than that !

That's taking the p***

There's a surprise!

I completely agree. I've come across looms that have broken in the door pillar area or where it crosses into the boot, but this has been on cars much older, not after just 4 years.

I'd find a good, recommended local auto spark to sort it for you if you don't feel confident to do it yourself. I can't see it costing much to repair ....certainly doesn't need a new loom,

And you accepted this statement as true and correct? Did they identify the damaged areas to you and point out exactly what clauses in your agreement they were basing their decision upon? Do you agree with them that the damage identified isn't covered under your Extended Warranty Agreement? Get as much from them in writing for your future reference and actions as you can in any further communications/

Finally a sensible reply to the OP’s thread .

Thank you for your reply and advice. The damage apparently was to the wires in the boot and the exclusions in the extended warranty states that it doesn't cover Wires and Wiring Looms. What caused the damage I do not know as it wasn't explained, but I will endeavour to get this in writing from them. Fundamentally a car of this type, cost and relatively young age should not fail like this.

 

[Tony Dyson]

Do you have any pictures of the damage in situ?

That's a standard clause in extended warranties, whether in a manufacturer's name, or third party.

How long have you owned the car and did you buy it from a Mercedes dealer?

4 years from brand new and from a Merc dealership

The MB dealership offered to fix it the non-Mercedes £9,000 recommended way (which is odd considering they are a MB dealership) and for £1,800 which I declined, obviously.
