GS Hot Start issues

[BRR]

Waiting for the part to come in, eurospares estimated 7-10 days, will let you know how I get on

I think I've finally got this sorted, today I had the thermostat (230890) and the fan resistor (263140) replaced. The thermostat seemed to be sticking open and not getting the car upto temperature and the fan resistor had corroded away to pretty much nothing so was obviously not functioning. The car now gets upto temp (about 90) pretty quickly and I've tried a few times starting the car after stopping for a very short period and it seems fine

So although P0128 points at the temp sensor it's more likely to be the thermostat or resistor, this is something one of the chief techs at Maserati UK has also informed me

Hope this helps anyone else who has the same problem

BRR,
Excellent report, a good guide for GS / 4200 owners with similar issues.
Cheers

I've done about 500 miles in the car since last tuesday and it's now running great, problem is definitely cured

well took it for a service and discussed with them about your solution, suggestion from them instead paying out for these parts (~£100) was to have a software update, which has a pre-req of the new temp sensor which we've both had.

So far so good (only filed up once), Will see how this works out and report back

BRR - Maybe worth getting this update

Filled up today, had a van waiting behind me - oh please start and it did, it didn't even struggle - so seems mine is also fixed

so fix for me seems to be replacement coolant sensor and software update (BRR had a different fix for this issue)

Strange that we had seemingly exactly the same problem but completely different fixes, glad you got it sorted though

thank you - after what you said had fixed yours, I wasn't sure an update on mine would make any difference - yep very strange. also like you experienced - mine also seems to drive a little better
