Another simple, routine job.
Change the aux belt and the MAF.??In all fairness, changing the aux belt wasn’t that hard. Access is limited, but it could be worse I suppose;

It wasn’t the end of the world though just need to disconnect the two pipes and looses a couple of brackets to get enough clearance.?
New v’s old belt, even though it didn’t come in a Maserati box, it’s the same thing…

It needed changing too:

Next up on the to-do list was the MAF - My Dad had found a genuine new one on eBay going cheap so, with them technically being a service item, we thought we’d change that.
We could have just swapped the sensor element out by removing the 2 anti tamper screws that hold it in the MAF body but I wanted to check the condition of the air filter.
Which is where things started to fall apart, both fugitively and literally.
The removable panel you gain access to the filter wouldn’t come off as the retaining screws were seized;

Of course, that wasn’t a simple task either as it’s mounted to the shell using threaded rubbers bushes. Half of which were also seized, meaning that the air box wouldn’t come out either.
It was at this point we realised that the outlet from the air box to the MAF was also broken. (Insert several expletives here…)
The solution to getting it out was to loosen the front bumper on the one side and the head light / foglight to give enough clearance to get it out. Oh and the front grill. And the wheel arch liner…

The air box looks like it had been repaired (badly) before. But, using some (expensive) epoxy super glue, my Dad was able to fix it, whilst also repairing all the corroded fastenings

There was no way the airbag was going back in with the bumper in place though. It may be possible but the risk of breaking something was too great. My Dad have been there, done that before.

Going back to the MAF.??The new MAF (body) which came in a genuine box bearing the PN…

Which is the same as the MAF that was on the car;

However, the sensors themselves have different PN’s:
Old one:

New Sensor:

Given that the new sensor is a genuine part, it should be the right PN but the car doesn’t seem to like it when it’s cold. Feck knows what’s going on there, if anyone could shed any light on this, it would be appreciated.??This effectively concludes the 3 day saga that was the simple job of replacing the MAF and Aux belt….
Except it doesn’t…
