Kohler Motors - Parow

Super people to deal with but totally the opposite when it comes to the end product. My vehicle was in the garage for over 4 weeks - got it back on Thursday PM....R60k later....I have done maybe 8 km's since I got it back....went up to Plattekloof Village today & the "engine malfunction" icon is on again ??? It will now be going to Mercedes Benz, Century City & Kohler Motors will be picking up the account....
