bottlid showing as unlocked/needs to be opened with key

[Ozmurc]

Hi All,

My QPV started off with the usual issue of re-latching the bottled whenever it was opened by the key, or the dash button (but if you opened by the bootlid release by hand of course it opened).

Now when you close the bootlid, it catches, but doesn't "tuck down" (ie doesn't pull itself into the final locked position). None of the buttons work to unlock the bootlid, and when the car is on, the bootlid open diagram shows on the dash.

If I open the bootlid, and depress the latch with my finger, the boot light goes off, and it will unlatch via the key, the dash button and the bootlid button, so its not a short circuit of the latch.

I'm surmising it either needs a new "trunk compartment control unit" or less likely, a new latch (as perhaps one of the microswitches on the latch doesn't work when its closed).

Any thoughts anyone?

Tried a battery reset? I was freaked out when my QP boot went all spazzy (can we say spazzy?) after a Flt battery and I didn't do the reset dance...

I took the boot compartment apart and checked connections with a multimeter, but didn't do a reset.... guess it can't hurt to try. I'd not thought of doing it as my car is always on a battery tender when not driven, but its driven 3-4 days per week anyway.

I guess I'll give the reset a go tomorrow... bit like the Microsoft reset...

Try this solution..... thanks to reviewing the US MaseratI life forum. On my 2009 QP it took less than 30 seconds to fix and just involved turning the key in the manual opening lock on the boot lid, holding it fully turned for a second or two while simultaneously pressing the electronic boot release button on the lid. Suddenly the selonoid burst into life and everything ( all switches and buttons) were working normally again. So no battery reset needed this time or a 2hr round trip to Bowker Maserati to fix it and charge me something outrageous for doing so. Got to be worth a go.

For those that are wondering, the car is fixed. The issue was not the trunk control computer, or even the latch, nor the adjustment. As noted on the American site, the wires that go from the bootlid to the car/chassis via an accordion/flex tube, can break inside this flex. I had one wire outright broken, and 2 wearing through. Oddly this meant everything worked when the bootlid was open, but not when the bootlid was closed (guess the wire stretched or something). I guess with age these things can happen..

Have heard this can be a problem - Migliore cars sorted mine.
