I've been battling a check engine light on my 2015 Wrangler for months now, code P0420 popped up and stayed no matter how many times I cleared it. Two different garages in Mussafah told me I needed a full catalytic converter replacement for almost 4,000 AED, which I wasn't ready to spend on a ten year old car. A coworker suggested I find a place that actually diagnoses the root cause instead of just throwing parts at it. After some digging I found a shop that offers a Jeep Catalytic Converter Fix Abu Dhabi – they ran a proper backpressure test and discovered it wasn't the cat at all, but a lazy downstream oxygen sensor and a small exhaust leak at the flange. They welded the leak, replaced the sensor, and cleared the code – total cost under 500 AED. It's been three weeks and no more light. Such a relief to have passed registration without a huge bill. If you get that dreaded cat code, don't assume the worst until someone actually tests the system. Saved me a fortune.
