Lessons learned
Never travel to Turkey with a low emission (Euro 6) diesel car or camper!
You are on your own. No garage can help you if something is wrong with the Adblue system.
Never trust Fedex for the arrival of a shipment!
They take your money but fail to warn you that your shipment will not arrive without huge delay and a lot of extra costs
As a privat person you cannot send a parcel abroad. At least not with Fedex! They immediately assume you are an export company.
In my experience they are either just stupid or they are trying to scam you.
Don't count on your insurance to find a creative solution!
They refer you to the emergency center. There is simply no space of support for creative solutions. Emergency centers operates according to standard scenarios, which simply means: repatriation.
At all costs; avoid airport SAW in Istanbul.
Turkish Airlines and daughter Anadolujet think it is pretty normal that people has to sleep in the departure hall. Even when they are the cause of it. The toilets at this airport are terrible, sheer filth.
Are you traveling with your dog in the hold and arriving at Schiphol?
Be alert when unloading. If Swissport (baggage handler) has not delivered your dog 30 minutes before the plane departs - ring all the bells! Otherwise the dog will simply fly back.
The conclusion is simple. Will your car break down with the Adblue system in Turkey? Annoying! But you can save yourself a lot of frustration by initiating repatriation right away. Due to ridiculous rules and procedures in turkey, this is also a complicated road (turkeyisnotreadyforeurope) but it saves you time on solutions that, in retrospect, are not possible at all in Turkey.
We have been behind the phone and laptop for days, but Customs in Turkey is unrelenting. They don't care what misery they cause and they don't care that YOUR car part is installed and then you leave the country. They just want to see money, a lot of money and they take their time for that. And watch out for Fedex. They most likely misinform customs so that you have no chance of getting your spare part released.
I will never ever again enter Turkey with a low emission (Euro-6) car that makes use of Adblue. The risk is too big!
