Probably nothing but does yours have the fuel cut off under the seat? My old 145 used to trip if the seat was dropped too quickly. I guess it was mechanical though. Any immobiliser or anything silly that needs reprogramming? I ever driven a 147 once as a courtesy car.

No idea about an immobiliser. I mean it has one, but there's no CODE light on the dash, which I'd sort of expect. I need to check the manual tomorrow

How many wires go to the solenoid?

Could it be that there is a micro switch within the solenoid that feeds back to the ecu and its faulty so the ecu thinks it’s locked when it’s connected and doesn’t send 12v to the solenoid

Well two for the solenoid and three for the alarm (at a guess). The ECU doesn't care if it's locked or not. I can lock it, and still nothing happens if that makes sense.

Hi there.
As a 147 owner I must admit I haven't come across this problem on the 147.
However not quite the same but my wife's Grande Punto and Mito had an issue with the boot lock not triggering the boot light despite appearing to be fine when tested and the feed wire also appearing fine. The problem was in both cases a corroded terminal within the lock mechanism that required a new lock to cure.
By the way have you had the water leak into the passenger footwell yet.?

No leaks, no obvious corrosion.

We've had the car for about 85k miles so better the devil you know. It's a great little car to drive :)

Still makes me think lock position sensor related. Have you tried the key in the lock itself?

At least it’s open, I’d finished a triathlon, went to put my bike in the boot of my e34 saloon and boot wouldn’t open. The rod had fallen off inside the lid. I had to drill a hole in the boot lid when I got home.

Mines a 2007 1.6 Sport which is my everyday run about. It's my third 147 and has only done just over 70,000 miles and I'm the second owner. Anyway late last year it suddenly started to fill up with water in the passenger footwell - it had been fine until then. Ended up with the front wing off to cure the leak.69419

There is no key in the lock. If there was, I'd just open the damned boot with the key. But you can't. There are three ways of opening it:
  1. Button on the dashboard: Works rarely, even though you can hear it trying
  2. Button on the key fob:Works rarely, even though you can hear it trying
  3. Fold down one of the rear seats and climb over the **** in the boot to get to the tag that the solenoid pushes on and push on it...

It's like a GT....
....only worse

On mine you’d swivel the badge and there’s a key hole underneath

On ours, if you swivel the badge, there's a loud splintering noise and then still no key hole, and a bill

That's right. Definitely nowhere to stick a key.
Bit like my 75 which has an emergency plastic release cable under the rear seat which is more likely to fail than the normal cable release by the drivers seat . At least with the 147 you can get in the boot by lowering the back seats to release the lock

On more thought have you checked the solenoid is earthing ok?
Click to expand...

Not explicitly, but I figured that when the solenoid was plugged in and I used my little Sealey probe to apply 12v to the correct line it triggered every time, it was somewhat superfluous. Happy to have that challenged, though.

PS the solenoid (plunger) has two cables. 12v and earth. It doesn't earth itself via a bolt or anything like that.

if you're really stumped I would just buy a second hand good working unit and give it a try, could just simply be a faulty unit

It's really not faulty, I don't think. It works every time if I apply a good 12v to it. The issue (I am sure) is that whatever sends the 12v from the dash button and the key fob isn't working

Ah, guess it must be earthing then. I figured you’d connected both sides of the solenoid to a separate battery to check it.
