Faulty Lambda Sensors and failed Catalyst on Porsche
Discussion
Porsche GB final comments on a Catalyst Failure at 26,000 miles ..a £1500.00 job (no goodwill forthcoming) 6 months and 1500 miles after Warranty job replaced failed Lambda Sensors free of charge (engine warning light had come on ) is " Lambda Sensors are NOT known to cause a Catalytic converter to fail. However a defective Catalytic converter can cause a false indication of a sensor failure . After replacement the Lambda Sensors need a period of time to adjust..hence the 1500 miles before the engine warning light came on again etc "
Surely faulty Lambda Sensors can and do often cause Catalyst failure..Would love any advice ..thanks
