3 times now in the two weeks I've had the Sele, the gearbox seems to have put me into Neutral while I've been pulling away at roundabouts!

It's really awkward as I've found the revs shooting up as I go nowhere, then had to put the hazards on and come to a stop in the middle of traffic before it would let me go back into gear!

Any ideas what's up? Just had the gearbox and callibrated this week, it's done it before that too.

Unfortunately not. Bought it Private, with a 'Sold As Seen' Receipt!

I keep getting paranoid that maybe it was just me knocking the stick into neutral, as if I was reaching for a gearchange liek a manual, but I'm sure I'm not lol! Plus putting it into neutral while moving always let you engage the same gear again, I tried it!
It's very odd!

Were there and warning lights when it dropped to neutral.

No lights at all that I can see. Only the fact that every once in a while I have noticed the gear number flashing for a while then stops again, though not at the point it changes itself to neutral.
What does that mean?

There is a feature in some versions of the software that if the pressure drops to a low level it will select neutral on its own.

It will not log a fault for low pressure.

Does it actually put you into neutral or are you accelerating as it automatically downshifts? If it is the latter you need to be careful to preselect the correct gear in those situations. The selespeed will automatically change down at 1000 rpm so if you think you will need to go to first gear - preselect it! If you accelerate as it changes down it will rev as you are in neutral.

It shouldn't rev because it wouldn't be in neutral, it is just mid-gearchange. While it is mid gearchange it disables the throttle anyway.

well it did it again this morning when the car wasn't 100 yards from my house. Had the turn the ignition off for a good 5 seconds before it decided to work again! Getting pretty annoying!

I'm pretty confident I wasn't revving at all, just braking as I approached the junction. I noticed after I restarted it that the number stayed flashing for a while through first, second and third and finally went away when I picked up speed. I'm constantly watching the dash now as I come to any junctions, so next time it happens I can be sure what exactly I did.
I phoned Avanti autos and discussed what it might be (not that I can remember now!) But a couple of simple things to check would have surely been checked at Alfaworkshop while they callibrated the Selespeed and clutch for me wouldn't they? I may phone Jamie back and see what they did and didn't look at, to work out what else there is to check over.

Jamie's saying that it doesn't necessarily mean a low pressure fault, just a sign that there's some sort of fault. Apparently fixing a Sele problem like this can get very expensive! The first thing he said to me before I even explained it to him, which is encouraging!!

I read on here about somebody else's Sele problem that cost hundreds to diagnose, but only needed a £6 relay to fix.

To save money and hastle, shall I just replay the relay first and see if that cures it? £6 would save me cash on the trip to Alfa Workshop I wouldn't need! lol

If so can someone let me know where to get one and exactly where it goes/how to change it? Can I do it DIY or would it need specialist kit (computers etc)?

It is just a std 5-prong 50A relay.
On a 156 it is located in the group in front of the battery.

No special equipment needed, just remove the old relay and fit the new one. Once you have worked out which relay it is!

Oooh, didn't realise it was as simple as that! Like you say though, a matter of figuring out which relay it is! May try that I have a spare 5-prong relay somewhere!

Surely a relay is either going to work or not though? this kind of occasional fault is a bit odd

The relay is only activated to power the pump, which will only be as required to maintain the 50bar pressure in the system.
It isn't on continuously.

The brushes in the pump motor also start to go after a while, which means a new pump unless you can find an auto-electrician to make and fit new brushes in th motor.
When the brushes start to go, a bump or vibration will get it running again, which is why the problem often happens most at low speed or while stationary.

Pumps are about £200, so are at the lower end of the expense scale...

Is there anyone on AO who'd have any kind of layout diagram for the fusebox?
There's none in my 147 that are the regular cubic shape like the spare I've got. These are smaller and rectangular. Do you think they'd be an Alfa Only part? I'd happily spend a tenner or so trying a change of relay before paying a garage any more.

The small rectangular relays are probably only 30A

It should be a 50A (Alfa p/n 46520419).
Are there no relays near the battery in a 147?

Right in front of the battery is the fuse & relay compartment. There's one big square relay in there in the middle, and lots of smaller rectangular ones around it. I think it was only 4-prong though. Anyhow it wasn't the same as the one I had spare.
Do you think this must be it?

Just checked my stash of old relays (I changed all mine last year!), it is only a 4-prong relay.

But it is a 50A p/n 46520419

That's the fella!
Many Thanks David! I'm going to order a replacement one, it's worth it for the money, I guess the chances of it beng the cause are slim, but it makes sense to start with the cheapest bit to replace!

Do you think I should disconnect the battery while removing the relay? Would it make a difference?
