Avoid BB Auto Hatfield at all costs!

Bitterly disappointed in BB Auto Hatfield-Took my Nissan Navara in yesterday 28/08/2018 for a checkup as it was loosing power and had black smoke coming out.Previously had the same issue and costed me R495 to clean the air flow meter at a different Nissan branch.Yesterday I was told by BB Auto Hatfield that my Turbo has a problem and cost will be an open order starting from R3500 until they find the problem.I told them it wasn't the Turbo as you can still feel the power kicking in it just looses power when nearing 100km/h.They told me this is what the machine says.I asked for the branch manager but he wasnt available at the time apparently.I collected my vehicle after I declined their offer and took the car to Imperial Nissan Menlyn today and was told its only blocked air filters and the airflow meter needs to be cleaned up.So BB Auto Hatfield you are a bunch of ********** trying to take people for a ride.Will never use you again bunch of croocks
