It was a job I had done last year when the ARBs were fitted and brake lines remade @McGrath Maserati.How easy did you find the crank sensor to change?
I checked the fault code and it has just the 1, P0128 - Coolant Temperature Below Thermostat Regulating Temperature.
Fair enough, see how you get in.
It might well just be the carbon canister rather than the valve anyway, has you changed it recently? Does the hot start problem occur after you have filled up the car or all of the time?
The wash valve is in stock with Eurospares - 180861.
Worth ruling that out for £20 + the dreaded.
Nice one...You beat me to it...
Purge valves NLA? Really....where did you try ?
I've swapped out coolant temp sensor and carbon canister firstly..
....followed by purge valve and crank sensor.
I didnt have fan issues...
Mine throws a similar fault but without the CEL.
When the code is stored, it puts the car into a sort of limp mode (disregards the sensor?) where the fans run at high speed and the throttle response and gear changes aren't as good as normal. It usually happens in the winter when the car has been stood for a few hours and then started again.
Deleting the stored code restores normal behaviour.
I suspect it's the temperature sensor and maybe the thermostat, which I'll hopefully get around to changing soon when I do the heater matrix.
Cheers,

I have never had a CEL either. I did hook my live data reader to see what coolant temps I was throwing up after I had cleared the faults as my temp gauge always seemed a little low. Coolant temp was showing around the 90 deg mark although the gauge reading just below 80. My resistor and connectors can be seen belowView attachment 68293View attachment 68294
What is the obsession with the carbon canister? I assume it'll be an Alfa part or something similar and we (my Dad and I) have never had an issue with one in the last 20 years and over 40 Alfa's?

Probably the same issue then.Yep, I think mine is going into a limp mode too. In fact you've pretty much described the symptoms mine has. It's difficult to drive when it's cold, which coupled with cold pilot sport cup+ tyres has lead to some interesting moments.
It’s not an obsession, it’s born from experience.
It’s basically a box filled with activated carbon that absorbs and stores fuel vapour from the tank (mostly, but not always, when filling up) and this is then let back into the engine by the wash / purge valve.
Over time the carbon gets saturated and it doesn’t store the vapour as well, resulting in a big slug of very rich fuel vapour being dumped into the engine at startup which makes it seem flooded.
No, it isn’t an Alfa part, OEM only sadly.
For the record, I knew what it does and how it works. I just don't understand why the users here are so quick to suggest it's the problem. My experience of them is that they rarely fail. Is it a know failure point on the 4200?
