B Class B180 Diagnosis problem with Service partner
I own Benz B-180 2011 model (W246). Two weeks back I got an "Motorlkontrolleuchte" warning lamp ON. Went to Mercedes authorized service center After doing big check, they said "Zündkerze" is problem and replaced. Within one week, after driving 300km I got same problem. I doubt that the diagnosis done is not correct. Now should they do check the problem without asking for additional diagnostic cost? Any similar experience and advice helps me to deal with service partner.
Thanks in advance
Suresh
