Yesterday I failed an MOT on emissions.
The computer showed up a Lambda fault - so the indy replaced the O2 sensor. The car failed yet again - and only passed after they borrowed a MAF from another car.
1. Does it make sense that both were defective - or was the replacement of the O2 sensor unnecessary?
2. Until I get a new MAF - what affect does a defective MAF have on the car? eg petrol consumption, Performance?
3. Do I need the whole "T" or is this enough:

Lambda
Looks like another bit of garage guesswork with the customer's money.
A duff air sensor would prevent the mixture from being corrected by the lambda signal, hence the lambda error message. A good diagnostic engineer has to see beyond the basic symptom to find the cause - that's what they are paid for.

SYMPTOMS OF A BOOST JUNKY
1. You get excited when it's cold outside.
2. You fill up every three days.
3. The size of your grin is directly proportional to the amount of boost you’re on.
