Diagnosed was not done properly

Good day.

I am very concerned about the way this matter has been handled. I brought the car in last week, and only yesterday I was told that four injectors are leaking diesel and that this is allegedly causing low brake pressure, no power, and smoke.

However, the car starts and drives. I collected it today and it is still running, with normal fuel consumption. Based on that, I need a clear and convincing explanation of how you concluded that four injectors are the confirmed cause of the problem.

You are asking me to approve repairs of R76,000. That is a significant amount of money. I cannot agree to replace four injectors on a trial-and-error basis. It is unacceptable for me to pay R76,000 and then be told that if the problem continues, you will “run more tests” and charge me further until you find the actual fault.

From last week until yesterday, no clear diagnosis was communicated to me. I need:

1. A written diagnostic report. 2. Proof of the injector test results. 3. Confirmation that the injectors are 100% the root cause of the issue. 4. Clarity on what guarantee I have that this repair will resolve the problem.

I will not approve any work until I receive proper documentation and assurance. Please respond urgently with a detailed explanation.
