Hi guys. Please help.
I know there’s probably threads about this already, but I can’t find the correct one and I need help ASAP, as I’ve got my MOT today.

The car has been sitting for a while and when I put a new battery on, the starter seemed to struggle but it did start.

Today it wouldn’t turn, but did bump start.
I left it running outside as I thoughht it may be a low battery.
When i came out it had cut out and would not turn over.
Put it on jump leads and changed battery. Still not turning.
All lights on dash seem to come on fine and go off. (Unsure if i saw the immobiliser light come on usually (yellow key and car?) but it’s coming on now and going off along with the rest).
Won’t bump start not either.

I have read a few threads and I was going to jump from battery to the starter direct, but not sure exactly how to do it.
What do I use to jump it and where do I connect each end to?

Thanks in advance 🙏

ps.
It’s definitely low on fuel, but I don’t think it’s empty.
Could running out of fuel cause it to not turn over though?
Doesn’t make sense to me…
It’s actually not even making a clicking noise when trying to start

Sounds like a large power cable failure. Check main grounds and terminals are tight.
thanks for getting back to me so quick.

battery terminals are tight.
Can’t really see where the earth goes, if that’s what you mean?
It goes under the battery. I’ll remove the battery again now and see

Ok so I took the battery tray out.
Ground points seem fine and tight, although a little corroded.

I’ve taken pics of the earth point under battery box, on gearbox and of the plugs on the starter. They all seem fine to me.

Not the prettiest but not the worst.

Put a jump lead between the ground of the battery and the block and try. Then positive and starter and try. If it works, there's your issue.
I’m not thick, honest haha, but I need to make sure I’m getting this right, as I don’t have a clue about the electrical side of things…

so with battery connected, I connect one jump lead to the negative terminal and the other end to the earth on bodywork, then try starting the car with the key?

if it doesn’t start, I then connect the jump lead to the positive terminal, and the other end to the starter?
If correct, which part of the starter? The part where the lead is coming from the battery terminal?

Thanks and apologies.

Whatever that wire is below the lead connecting nut, is rusted through and snapped.
New starter it is then.

Am I right?

but that wouldn’t make it cut out and unable to bump start though would it?

Just managed to get the starter off the sdi and matched it with my one.

Where it goes into the box, the tdi one has a longer bit by the shaft.
Everything else seems the same.

Im gonna try it, but do you think I need a different part?

I’m not sure which is the part number but I can see:
Tdi 001 125 012
Sdi 001 125 005

Ok so I just googled the part.
It’s 0001125002.
Google reckons it’s Bosch 2kw 10 teeth.

Now that part is over 200 quid.
There is a cheap one on Autodoc for £48, but it’s only 1kw.

I know people will advise to get the best part, but I only need a temporary fix, as I will try and fix the one that’s come off.

If I go cheap, will 1kw start my car?

cheers
