Bad car dealer service

Dear Sir/Madam, I am writing to formally lodge a complaint regarding my recent purchase of an Audi A8 from your dealership, Fourby, and your failure to honor the signed agreement regarding the vehicle’s faults. When the sale was concluded, it was clearly acknowledged by both parties—and documented in the Ombudsman certificate signed by you and myself—that the vehicle had two major faults to be repaired at your cost. These included: 1. Adaptive Cruise Control (radar sensors) 2. Audi Guard Braking System 3. Park Distance Control sensors Despite my cooperation and repeated attempts to allow your dealership the opportunity to rectify these issues, the following occurred: - I left the car with your dealership for a week, only to find upon collection that no repairs had been carried out. - After confrontation, your dealership requested a second attempt, and I agreed in good faith. At your instruction, I delivered the car to the Audi dealership at 7:00 AM, where an official Audi diagnostic confirmed that the main radar sensor was faulty and required replacement. - Instead of resolving the matter properly, your dealership attempted to source parts and once again requested I leave the car in your custody for 12 days. - Prior to collection, your owner confirmed in writing via WhatsApp that the car was “perfect.” However, upon testing the vehicle immediately after pickup, I confirmed that the Adaptive Cruise Control was still not functional. - Further investigation revealed that instead of repairing the faults, your dealership had tampered with the MMI system software by removing the Adaptive Cruise Control and Guard Braking options entirely, creating additional faults, including irregularities in the brake self-switching system and malfunctioning PDC sensors.This conduct represents: - A breach of our signed agreement under the Ombudsman certificate. - A deliberate attempt to mislead me by software manipulation, which may also constitute a violation of Audi’s global software protection policies. - A complete disregard for customer rights and good business practice. I hereby demand the following within 7 working days of receipt of this letter: 1. Full and proper repair of the Adaptive Cruise Control, Guard Braking, and PDC systems at an authorized Audi dealership, at your cost. 2. Written confirmation from Audi South Africa that all software and safety features have been restored according to manufacturer standards. 3. Alternatively, a full refund of the purchase price should you fail to remedy these issues. Failure to comply will leave me with no option but to: - Pursue the matter through the Motor Industry Ombudsman of South Africa, - Escalate to Audi South Africa and Audi AG Germany, - And, if necessary, take legal action for breach of contract, misrepresentation, and damages. I urge you to treat this matter with the seriousness it deserves and respond in writing within the stipulated time fream
