DIY Repair Success: How a Teenager in New Zealand Saved Thousands

Meet Arshia, an eighteen-year-old living in New Zealand. Arshia’s journey began when he bought his first car, a deregistered Mercedes SLK 230 Kompressor, in April 2022. In Australia and New Zealand, a deregistered car is a vehicle removed from the official registration records. This can happen for various reasons, including when the vehicle is no longer considered roadworthy, if it has been written off due to extensive damage if it has not been re-registered after the registration has expired, or if the owner decides to take the vehicle off the road voluntarily.

Deregistered vehicles cannot be legally driven on public roads. They are not covered by third-party insurance (CTP) and do not have a valid registration sticker or plate. To put a deregistered car back on the road, the owner must re-register the vehicle by passing a roadworthiness inspection, paying registration fees, and obtaining CTP insurance.

To pass compliance and become road legal, the car needed a comprehensive service and a resolution to the SRS light issue on the dashboard. After struggling to find an affordable mechanic experienced with German cars, Arshia eventually found one who charged him nearly NZ$2,000 ($1200) to repair the SRS issue. The exorbitant cost and the challenge of finding the right mechanic inspired Arshia to explore DIY car repair.

Determined to find a more affordable and efficient way to diagnose and repair car issues, Arshia began researching diagnostic scanners. Choosing the right scanner was critical but challenging due to the expense and the technical jargon surrounding the products.

The SLK proved quite challenging as soon I had to deal with a non-starting car. The car would crank but refuse to start, leaving me unsure of where to begin diagnosing the issue. With determination, once I acquired the YOUCANIC scanner ready to tackle the problem head-on. The YOUCANIC scanner revealed a P0335 diagnostic trouble code (DTC), indicating a Crankshaft Position Sensor ‘A’ Circuit Malfunction. With this newfound knowledge, I ordered a new crankshaft position sensor and set to work on the repair. After installing the new sensor in less than two hours, resolving the starting issue and bringing his SLK230 back to life.
