Thanks Matt
I’m sort of pleased to know that at least I’m not the only one suffering! However, since I originally posted I complained to MB central, and also spoke to a different MB Commercial franchise, who were much more honest. They said ask them to check the turbo again as it’s more likely to be a known fault on a seal on a pipe on the turbo. I went fairly nuts at everyone, and suddenly all items were fixed free of charge, the truck was washed and I got a ‘sort of’ apology. Utterly outrageous. Mertrux were caught with their pants down in other words, trying to replace £5k of turbos and intercooler that weren’t even faulty! I would get rid of mine but think I’ll keep it until an electric truck finally comes to market

obviously not a Merc, awful service.
