need help asap 300tdi

Just pulled out of the garage and the it wouldn't move. No drive in any gear auto. Stopped the engine now it wont start any ideas what's happend. It was driving fine this morning and yesterday.

Have you checked the high low gear stick is in engaged?

Yes, its turning over and seems like it selecting gears ok. But the starters just not turning the engine over.

It could be the inhibitor switch stopping you from starting the vehicle. Manual myself but I have heard of this happening.

have you checked the voltage on the battery?

The starters working. Its running the starter motor etc, its just that the engine doesn't seem to be turning over. I don't know a great deal of how the autobox works. inhibitor is bypassed it seems. It's like a clutch has gone only reverse worked. Oil looks good and is full.

Is it throwing the 'Bendix' bit forward tho ?

If it is, it may not be engaging the flywheel ring gear or worse you some teeth off it

May be best to take starter off to bench test and inspect

Ill get the starter out now and see.

Clutch pqcka run several gears at 1 time.so you shud have 2 gears.

Starter off and working fine, teeth are all good and on the flywheel but I can turn the flywheel with fingers with barley any resistance. Is that right, I don't know if the autos are different to manual but I know I wouldn't be able to turn the flywheel with out it turning over the engine on a manual

Mmmm, not good

either the flywheel ring gear has detached or the flywheel bolts have sheared --- ahh, then there's broken crankshaft, but you have an auto !!! so that's the driven plate, which is mounted slightly differently

as I said not good, sounds like a 'box off job

If you have a pit or access to one take the box off, if not take the engine out

Sorry mate !!

drive plates have a habit of shearing ,youd need box or engine out to cure but ring gear turning with no resistance would suggest so

Flywheel gear spinning free means the flex plate has broken through at the middle where its bolted to the crankshaft.
Its now being held in place by the bolts attaching it to the torque convertor.
Its a box out job and you are gonna need a new flex plate from Ashcroft.
Wouldn't recommend a used one from breakers because they most often than not develop microscopic cracks in them after extended use leading to what's happened to yours now.

or google ftc4035

Cheers guys looks like the flex plate then engine was still running perfectly fine when it lost drive. When I spin it about I can feel it's loose at points I can wobble the drive plate. Going order one from ashcrofts going to have to stick it in the garage to get it done. Annoyed, worst is not being able to do it myself I just don't have time and space. Been quoted 100+vat labour and parts on top but got a two week wait.

Thats good rates because doin the box out is a pain in the arse

Yup, it sure is.
Although personally I prefer taking the engine out myself. I find its an easier task compared to trying to balance the combined weight of the box and transfer case underneath the vehicle.

We took my mates out on a ramp.dropped transfer box off 1st then auto box.them 2 combined i wouldnt like to lift or balnce on a transmission jack.

To good to be true, when I called to book it was priced different he must of misunderstood me. 250- 300 plus vat. Going to do it this weekend and pull the engine instead to do it.
