Cant start my bmw320d 200

sure you can the operator guide on all cars glove box there.
shows park neutral lock out.
Key on, step on brake key on, shift to neutral. (battery not dead)
do not tow it with steering lock enabled. that be horrible.
all cars have a chapter on towing,
wheels up or down front or rear up or down or flat towed

and with RWD and wheels on ground rear, the towing distance is limited to 200 miles or less. so when the rear transmission bearing runs dry and not burns up, < all you need to know there!
most transmissions made (not my 64 Pontiac rotohydramatic)
has the 200 mile limit, the transmission has no rear tail shaft pump now days, ALL TOW shops know all this stuff.
Same with 4wd and same reasons
my Jeep i can tow it 200miles, called flat towing but must stop and start engine every 200miles to add lube to the rear.(tranny shafts)
flat towing is the hard job and I bet you meant flat towed.
and hope only short distance,

lost the key?
battery dead Not told?
best is leave key turned on , hold foot brake, shift to N and then key off but do not set the steering lock ever. (pause and think now)
for some jobs (ask U-hual) they have a bar the locks the steering to FRONT, hard locked, so cars KEY lock can not engage.. towed.
if battery is dead ,jump it. then go to neutral
some cars vast the same manual
shows how to defeat the P/.N lock with a secret part of the shifter console we push that, and P/N is defeated just for towing.
we have no Iveco 3.5 ton curtain sider , in USA
nor any year told
ask the make for the manual on your car in YOUR country
"Today it is marketed in 110 markets around the world" but not USA

the guy pushed a button under my dash turned the key and car started

you need to know where that push button is under the dash

if you cant find it your self ... ring the place back for instructions

not nice but
you may have to get them to call out and show you or
tow the car back to where you got the battery fitted

you have to run the car then tow it or else you will fry the transmissions planetary.

oops didnt read how to tow that suzuki,oops.
how far you go , over 200 miles>?
is it an auto or stick?

flat towed??
dolly towed,?
towed from front or rear.?
we cant guess any of that and are all covered in the operators guide.
clear as a bell too.

towing cars , most will damage the rear transmission bearing.
because its dry when engine not running.
so the rules are very strict. due to that hard fact.
soon as you tow anything , thing, "rear bearings."
or if Fwd car, same on front.
most cars are not designed to be towed and some only short distances.

Try adding water absorb ant fluidd, ie heat. To fuel. May have condensed water in tank. Popped a fuse or breaker

The Battery has gone flat. When you tried to jump start it, this did not change the battery state its still flat.
I bet you will get the same code on the scanner if you remove the battery. Take the battery out and charge it with a battery charger overnight, then try it again.

Camshaft sensor a more common problem, but have a diagnostic scan done first to save spending on uneccessary parts.

dealer only factory immobilisor has cut in when battery went flat

maybe your battery can be dead.. there can be many reasons that it wont start.. or check to see if yr started is not working.. but the first thing that you want to check is the battery.. see if the lights turn on in the car or they don't call your friend put the jumping cables on and see good luck!

ok so looks like this one has been solved by the dealer.
I had it towed to them, and they said the battery had to be replaced (only had 8vlt in it)
and something to do with the cell inside the battery had failled. No surprise here - its the same battery which came with the car - 5 years or so ago.
They are still working on it, so wont know if its anything else. Battery's in Australia arent cheap
for this car - 125 dollars, and neither are most parts. But then i use the car for business, and drive everywhere. The car was used everyday, but i suspect it went flat, as most copen owners would know, seems to go flat if you dont use the car for some period of time, like 1 week or so,'
