Engine management light

driving home from work tonight the engine management light has come on but also the exhaust sounds like its started blowing im guessing its the CAT and a lambsensor dont know till daylight tomorrow and i can have a look where exhaust is blowing from
Suzuki O2 softtop 54 plate im sure the exhaust and sensor where replaced about 5YRS ago whats the life span of an exhaust road use only no offroading :ohmy:

The original ones usually last 8 or more years, the replacements 2 or 3, the eBay catalysts 1 or 2.

exhaust looks like its blowing from back box so dont tthink its lansensor thats put engine management light on going to plug it intp mates computer on monday so wheres the socket on jimny so we can plug it straight in on monday and make me look clever :whistle:

Under the dash above the right knee
