Put my car in on Friday. My result from mercedes:
Diagnostic adblue level not reading. That's £170. Before we replace the tank, we want to check the wiring as it may save you. It will be an other 2 hours labour tho at £170ph. Mercedes won't help unless we know exactly what the fault is, also as its Friday afternoon we will probably get back to you on Monday.
Phone on Monday to be told, you need a new tank at a cost of £1875. Also Mercedes have had a look at your case and say you are 100% liable for costs.
I am currently dealing with mercedes customer services to see if I can improve the offer.
Hi thanks for the update. I tried several head office but could not managed. I have been charged £1482 after little discount and £240 inc vat charged for diagnostic alone.
