It kept saying it was empty and would go to limp home mode even though it was full.... then it said it had bad DEF and to clean out tank......I took it to the dealer as I was still in my 5 year 100K powertrain warranty and they fixed it but I think they had to replace the whole system. There may be a service bulletin on it...... |
