So I bought a 2 litre mk3 mx5 not so long ago, and within a day the engine management light came up. Took it to a garage and they told me it was the O2 Sensor in the Cat, so they took it out, flushed it out and the light was out. Then 4 days later, it flashes up again. This time I took it to a different garage who plugged it in, and it came up that it was the actual Cat converter itself, not the sensor in it. He has reset the light (basically putting the issue to sleep for a while), but I am quite confident it will appear again.
Anybody had any similar experiences that they could help me with?
They didn’t specify the code, all I know is one garage said it was the sensor, and another said it was the cat. I’m fairly sure it is the second sensor that the first garage said it was, i’m assuming this because they priced a new sensor around £80-£90 which is roughly the price of the second, with the first being significantly more expensive.
Any idea how much a new cat would roughly be???
And Paul thank you, that would be brilliant. As I say, if and more than likely when the light comes back on, i’ll get it diagnosed and see what the problem actually is.
When the Engine Management light came on on my Mk3.5, the code reader indicated that it was the EGR valve which was to blame. Good luck in solving your problem.
Thanks guys for the help, I’ll have a look online about getting myself a reader and see what that brings about. if I get any further I’ll let you know!
