MOT failed lambda emissions too high even with new sensor!

[MRBILLYUK]

I would get any leak sorted as best you can, do you have a print out of the emissions failure info? As the exact part it failed in will tell you what part you need to address. :smile:

Sitting at idle revving the engine won't get the engine hot enough, it needs a good hard drive, maybe even add in some redex, it's old school and often joked about, but can work well especially come MOT time. For peace of mind, if you can afford it, just replace the front lambda if you think it's faulty but again, the test results will give a clearer indication of what you need to change etc for the retest.

That's exactly what I do . In fact did this morning . Half a bottle of redex into half a tank and took my car for a 30 min hard drive to make sure it was up to temp. Whether the redex actually works or not I don't know, but definitely make sure the engine is up to temp . Mine passed :smile:

Any recommendations on LAMBDA sensor pre-Cat?
Link would be helpful
Thanks.

Don't people just pm @George@RTR_Parts and buy the Lambda off him?

Saves faffing around trying to find the right one
