Have had a nightmare of an experience last 5 weeks!!! Battery died car got towed to dealer when it wouldn't jump on Sept 27.... Dealer took 2 weeks to tell me call insurance you have water damage to your wiring and electrical harnesses...Insurance took 2 weeks to agree to cover me for over $13,000 in damages to a 2017 E300... Dealer claimed they couldn't order anything until insurance cut a check, they pulled my right to a loaner car today...Saying even though its a $13,000 job its insurance money and not mine so I have no right to a loaner... Claim they will not know until Monday the time frame for the parts but are guessing, 2 weeks to arrive in the US and another 2 weeks to replace the parts... Anyone know if the engine and wiring harness is a stock part in Germany? A friend with a C class said they had to make his from scratch and its about a 3 month turnaround!!!

 

What was the cause of the water damage? Will that be rectified as a part of the repair? Was it not a warranty concern?

 

 

Dealer and Insurance both determined it was the negligence of a professional car audio shop that installed a radar detection system and never properly secured the grommet back in place. Dealer let me haver a loaner car up until the point insurance issued a check. It didn't matter it was my third car from them or that I have another coming off lease next month response was they never issue a loaner for insurance work. While I wasn't thrilled and thought they could help more considering the cost of the repairs, I understand thats the policy. However the whole we have no idea if and when the part is available could be 3 weeks or 2 months was really weird.

 

I'm guessing time is a factor, but is the audio shop not responsible in some way? In any case, for a proper repair the dealer may remove what was installed for the radar equipment. As for the loaner, that is difficult. If it was warranty work, they may have been able to justify it. That said if you are a repeat customer and possibly soon to be again, I'd think they work something out with you.

 

It's my primary car so time is certainly a factor. Insurance indicated they will seek a settlement with the Audio shops insurance/shop.I am guessing the dealer knows truly how long this is going to take and have no desire to tie up a loaner for 2 months.Still I feel like my only option is to use another dealer for my up coming lease.

 

Doesn't your insurance cover a rental replacement while your car is being repaired? My State Farm policy does.

 

 

No, I don't have rental coverage for a comprehensive claim... they didn't touch the harness they failed to properly seal the hole in the firewall for the radar detector wires running from the engine bay into the car causing water to slowly make its way inside the car...

 

 

It was big, they cut the grommet out completely. Wiring harness is in the footwell, all the water ran down into it causing the connectors to corrode

 

 

Are you sure this is the cause?

We have had two cases where the lower drain rubber for the AC evaporator was dislocated from factory causing major water damage.

 

I can only go by what Mercedes Benz and my insurance company ruled, they photographed the missing grommet extensively. Dealer just told me today the part needs to be made in Germany and is slated for production the 2nd week in January 2019!!! I placed a call to corporate in Georgia to see if they could expedite it or work on a loaner car since it is a very long delay... Have to wait and see...

 

 

Hey bro, same exact thing happened to me. 2017 E43, radar detector install before I bought the car (dealer sold it with it on) for 18k miles. The dealer also had it listed CPO, then apparently decided to not certify it and remove the CPO due to the radar. Dealer is telling me it isn't their issue, and the ultimate replacing of the wiring pin connectors would need a harness. The car is fine, didn't get to ECU but issues could come later on..

How did you end up on this? Really curious, I am in the same exact situation right now unfortunately.
