Misdiagnosis and I had to foot the bill !!!!!

I took my car to BMW Sandton for an intermittent electrical fault to be repaired. They "diagnosed" the problem and when I went to pay for the MPM (problem part), I said I would like the old MPM back in case it was not faulty and if so, they must replace the new MPM with the old one and credit me. All I got back was a big grin. The "faulty" MPM was replaced and when I collected my car, the fault was still there. They then said the BT module was also faulty and that it would cost another R14k over and above the R7k I had already paid. They refused to credit me for the non faulty MPM. I contacted BMW SA and after getting the technical department involved, they agreed with me that the MPM could not have been faulty and instructed BMW Sandton to refund me, to which they refused. After 2 month of emails, BMW Sandton finally agreed to credit me for the MPM only. I was now out of pocket for the diagnosis and the installation costs of the MPM. They would resell the MPM and therefore not be out of pocket at all. BMW SA got tired of the emails going back and forth and finally said there was nothing further they could do. After being a very happy BMW client for over 30 years, I was very disappointed with the outcome and BMW SA's inability to make their dealers refund clients. I will most certainly never use BMW Sandton again !!
