Drivers typically notice a sudden drop in fuel economy, rough or fluctuating idle, hesitation under load, a sulphur or rotten-egg smell from the exhaust, and in many cases an MOT emissions failure. On modern diesels and direct-injection petrols, a stuck or slow-responding sensor can also push the engine into limp mode.\u003c\/p\u003e\n\u003ch3\u003eFitment notes\u003c\/h3\u003e\n\u003cp\u003ePlug-and-play installation with the correct factory connector — no diagnostic coding required. Most engines run a pre-cat (upstream) and a post-cat (downstream) sensor; cross-check your existing part number and the position on the exhaust to make sure you're ordering the right one.
