Mot - fail

So just got a call to say the Alfa had failed the mot. It's emissions were merely double in hc, double for CO2 and was high on the third. What to do? Anyone know of any quick fixes/ obvious solutions? It has been lying for 6 weeks so the garage took it a blast up the motorway. No change?

The key factor here is the fact it has been standing for six weeks.
I presume the battery needed recharging?
We have to take into account that the car will be now running on factory default ecu settings for fuel and emissions.

Bear in mind that your sensors, injection system and MAF are old and over time will have communicated variable readings to the ECU . Therefore, when back in default mode, the ECU will make the engine run naturally rich thus the high readings.
It,s a tricky situation as the car needs to be driven for it to settle into adjusted settings via the ECU reading the older sensor values etc....
Then, you should find the values regulate and emissions return to nominal values. Unfortunately, that's difficult without an MOT.

Buy multiecuscan and see what comes up or get someone to plug it in for you.The values are affected by one and other so it need not mean everything is awol. Kindly note the car may have been outside the limits before it was laid up.
