Good evening Ladies and gentlemen.
After 5 hours of trawling the internet and this site I figured I would ask.

My 1997 gti-6 won't start. It will not turn over. The fuel pump primes and all of the lights on the dash are bright and it just clicks when the key is turned. It is one solid click from under the bonnet.
All fuses are ok and the central locking works.
I changed the coolant today and thought that I may have got the crank sensor wet but from what I have read it would turn over if the crank sensor was at fault, mine doesn't.
I have put the car in gear and tried rocking it but again to no avail.
I tried bumping it twice but it wouldn't go. (I was on my own and these things are heavy)
I tried using jump leads to a huge battery on a Saab 95 2.3 and again it did the same thing although when I was trying the gti it really slowed the saab's engine down.
Couple of strange things were the clock and thermometer display just alternated rhythmically between horizontal and vertical lines (see pictures).
And after I tried to start it every time all of the dials would wind around (see picture)
I put a multimeter on the battery and it was 12v, turned the ignition on and it dropped to 11.86v and when I tried cranking it it dropped to 3.5v.

Answers on a postcard please.

I am thinking battery or starter but really appreciate any of your opinions. Thanks.

Bayley

Those electrical symptoms are either a bad earth or the battery is on its way out.

Both terminals were loose on the battery so I replaced them both with new items.

After I had done the coolant it started so I went for a spirited 13 mile drive. Came home, stopped the car and then it wouldn't start.

I had a 106gti for 6 years and it reminds me of that, in that I am trawling the internet for answers all of the time and constantly replacing bits in a trial and error fashion. I wouldn't have it any other way Big grin

My 6 did that the other week when I tried starting with a battery that had been dead for two years, banged a new battery in and she was away, although mine did jump start off my van, I had to leave the van run for around 20 mins before I started the car

Either an earth fault or the starter has jammed. Check the main earth points from the gearbox, front wing, under the pedals and under the rear seats.

It sounds like you've got one issue, possibly two.

The first issue is definitely the battery. A good battery should read between 12.6v and 12.8v when it's doing nothing. Turning on the ignition should perhaps drop it to 12.4v, no less.

When cranking, the voltage should drop absolutely no further than 9v, a good battery will probably be around the 10v mark.

So that's your first issue. I *suspect* that the click you hear is the starter solenoid trying to engage but then not having enough power to do so and failing. A new battery will solve this. Yes

If a new battery doesn't solve this then you've got a starter issue as well as a knackered battery. However, you've definitely got a knackered battery, so replace that first. Wink

065 is a heavier duty battery and better in cold weather, should be 60aH capacity. Yes

No problem, just make sure you measure the dimensions of the battery box and when you go to buy the new battery ensure it will fit in those dimensions.
Some batteries which are listed for our cars are actually too big for the box. Doh

Update. Got a nice big battery but still have the same fault but I managed to bump it with the new battery so I have ordered a starter motor.....which turned up wrong so new one will be here in the morning.

Whilst this was happening my key fob has stopped working so I am hoping that is just the fob battery as like most of us I only have one key.

It's got to be an earth or shorted/stuck starter, if it was the battery it should have started on the jump leads.

    Seeing the tacho and speedo doing that definitely smells like an earthing problem. The digital clock will do that whenever its voltage drops low enough that it's time memory is wiped, i.e. if you disconnect the battery, but since the battery itself clearly isn't flat and is still powering the dash and making the starter click, I think you've got an earthing problem which as phillipm says, could well be coming internally from the starter motor.

    Sounds like the battery was bad but should still be able to bump start the car if it was.
    I agree that it will be a bad starter or a bad earth though.

    Grab a new inlet manifold gasket from Pug while you are changing the starter too Smile

    :Lol That's why it didn't work, the thin wires can't carry enough ampage through them needed to start it, if it was a 1 litre engine they may carry enough to start it but not a 2.0litre+
