9 weeks ago I bought a 2018 VW Tiguan 2

9 weeks ago I bought a 2018 VW Tiguan 2.0 TDI DSG from Motus Cape Gate for ±R350,000 (incl warranty & service plans). The vehicle wasn’t properly inspected pre-sale — at delivery I found a faulty mirror, broken window button, loose bonnet lever, defective aircon & no wheel alignment done. All only fixed after I raised it. A month later I flagged a slipping reverse gear to my salesman. On 23 April an emergency transmission warning appeared while driving. Diagnosis returned fault code P175E00 —a known documented failure of the DQ381 mechatronic unit, acknowledged in VW's own Technical Product Information bulletins. This fault recurred 3 more times. I now have a constant engine warning light. The vehicle is deteriorating & unsafe. I’ve requested a courtesy vehicle & submitted a formal CPA Section 55 & 56 demand for replacement or full refund of ±R350,000. Email sent 27 April 2026. I booked a formal VW diagnostic. I hope Motus honours their legal obligations without MIOSA or NCC escalation. I’ll update progress
