The oil pressure low sign came up on the dash and then vanished while I was just setting off???? I restarted the car and my range went from 32 miles to nil and refuel asap then needle was at the top of the red and now its right at the bottom???

I put a litre of oil in less then 150 miles ago?

I am letting the car cool down for 20 mins b4 I go check the oil?:confused:

I gave it 5 mins and checked as that was the the manual says, and the oil level is near the top exactly where it should be...I have checked multiple times?

Oil pressure and oil level are not the same thing though! Did you stall the car then the low pressure warning came up? If thats what happened its normal.

no not at all, I went over a very slight bump and then it just came on! I had been going over a lot of speed bumps 15 mins prior?

I restarted the car and it didn't beep but then said my fuel level was very low!

Just put £20 of fuel in her and the needle has gone back to where it should have, and there are no nasty sounds from the engine. I am afraid to drive it but need to go to work.

I am praying that its only a faulty switch, either way I will be giving alfatech a call on monday in hudds and asking them to look at it!

If the range was only 32 miles before then your fuel level IS very low...

Loose battery connection mate it would have been the bump that jolted it a bit but just enough to give it the heebeejeebee's

Take a look at the positive terminal
It has two rings, one upper, one lower. Make sure both rings are firmly on the battery post and the top ring not just sitting level on the top. Make sure the bracket that holds the battery to the tray is secure so it doesn't move.... Oh... And don't panic;):)

Will defo check this out, thanks for the tip! I will be booking it in with alfa tech to be on the safe side.

Just drove it 10 mils to work not a problem, sounds sweet.

When it came on it nearly tore me a new arse hole :lol:

I am hoping thats all it is!!!!

;) they could do with a god clean mate. But try these....
Next is to follow the negative cable to the inner wing, undo the bolt connection and give all the metal co tact surface a good rub with sand paper until it's bright and refit it nice and tight.:)
Do you have any baking soda or bicarbonate in the house mate?
If so, mix a couple of table spoons full with a pint of water to make alkaline water and pour a little at a time over those battery terminals and fuses... Don't worry it won't do any harm. Use an old tooth brush to scrub it in if needed... Watch all that crap dissolve away:D
It foams up, neutralizes the acid deposits that attract dirt, grit and oil and it all simply washes away as you pour and scrub... Try it and see:thumbs:

Will give this a shot tomorrow on my day off from work, if the weather holds out.

I take it I shouldnt start the car till I have dried everything properly otherwise something will blow a fuse?!

Also why all the connections to the positive terminal like that and whats that green thing next to the positive terminal? First time I seen a layout like that!

Slightly different to mine, I have the box of fuses on top same principal with all the extra connectors though. The green, brown and lilac look like permalink fuses, they are water tight and only blow on serious voltage anomalies to protect the loom...

You won't have to let it dry out mate, just let the water drip away for minute or so, dry off with a towel if you want to. I have steam cleaned my battery area before and it never affected any fuses so you will be fine;)

Just spoke to Alfatech in hudds and they have said unless the light is on there is nothing they can really check. They need the light to be on to be able to diagnose anything . If the oil is topped then that's all then that's all that can be done......bah

The only thing else that could cause an intermittent loss of connection and warnings for a split second while driving, especially going over bumps would be:
The main earthing cable from the gearbox. It can get pretty weak and groggy and all it takes is a jolt to cause loss of signal to the ecu, which is symptomatic of your oil and warning lights and then running fine afterwards.

A close friend of mine's V6 that I service for him had a very similar issue occasionally. The gearbox earth looked ok and tight but after changing it for a heavy duty cable from a local motor factor for the princely sum of £2.95, the mystery fault never occurred.

Think of it as preventative maintenance for future issues so nothing ventured, nothing gained mate.:)

As soon as the low oil pressure sign came on, I parked the car and turned it off, and then restarted it a couple of seconds later, and all good....I didn't wait for the signal to go away...I got scared lol

Also I spoke to Turin Motors, he said as long as the oil is full then its just a glitch ...unless its happening multiple times not to worry about it, its due its 60 thousand mile service, I might book it in with Turin..I had the cambelt and everything done by Alfa Tech

I also tried to trace the negative wire to the wing like you said but I could see it? I could barely follow any of the negative cables its pretty tight around there!

Shall I ask the specialist to change the earthing cables from the battery and the gear box when it goes in for a service?

You could do but if you remove the induction tube from the maf and throttle body you should be able to see the cable bolted onto the box itself mate;)
