Hi, my scudo won't start, pp2000 gives a code of P1108.

does anyone know what the code means on the scudo?

Cheers

so that code has a few different meanings. it can be a radiator fan high speed circuit issue, it can be a mass airflow sensor error, it can be a manifold absolute pressure sensor error, and finally it can be a cam position sensor fault.

so is it cranking and not starting?

well first question i have is, how long has it been since the cam belt was replaced? if a cam belt has snapped it will still sound like it is cranking normally due to the design of the valves (they never bend on these engines they just get pushed up then snap the cam shaft, take out the cam journal bearing caps and retaining bolts) i would check the cam belt for what it takes. (just some 10mm bolts)

as with all diesels when they crank but wont start, first thing when it comes to getting them going again is to unplug the mass air flow sensor which is the sensor on the big pipe coming out of the air filter. if it suddenly starts running when that is unplugged, change the sensor.

theres a possibility that the engine is not reading the correct cam and crank speeds. this can be because of a failed cam or crank sensor however my money would be on the crank sensor failing. if you get one of those OBD engine RPM gauges and it tells you that you are only cranking at 200 rpm then the sensor will be wrong. these engine need about 500 rpm to start and normally crank at about that.

i advise to take out the crank sensor and inspect it. if it has iron filing or bits of broke up magnet then it needs replacing and the flywheel speed pickup ring cleaning.

a HDI only needs 3 sensors to start and run, they are the cam position sensor, the crank position sensor and the fuel rail pressure sensor they are the only 3

some things to try.. hope this helps...

Hi John,

Thanks for your reply.

Yes it is turning over at 500+ RPM according to diagbox

Cambelt is fine as just replaced the injection pump with a newly refurbished unit, Was not starting before I replaced the pump. Crank and cam were pinned during this procedure so should be timed ok.

Unplugged MAF, still not starting and the diagbox detected that it had been unplugged.

I have replaced with new, both the Cam and Crank sensors.

Rail pressure sensor was giving results in diagbox (can't remember the number but it did not cause concern)

Have also tried another ECU, same fault on diagbox same not starting. Also replaced 1 x Glowplug and Glowplug Relay. In tank pump working ok.

My diagbox has failed so not easy to do further testing as I have to get someone to call in to run tests.

It failed after being laid up for some months and the battery being let to go very flat, so much so i had to buy a new battery.

I am going to check the wires from the cam & crank sensors to see if any are broken.

Any other thoughts appreciated.

it could be an immobiliser issue.. do you have any other keys you can try in it? dont forget they have the little RFID chip in the key. i have fried one before when i was playing with a magnetron trying to build something that can fry electronics at a distance.. and sadly my keys got hit.

make sure the little RFID pickup ring around the ignition barrel is ok. had one come unsoldered on another car once. cheap fix.
if it was the dw8 engine you can get them running without an ecu.. heh. however with the hdi being fully common rail you cant with ours.

make sure you have the right ecu plugged in too, if you do not have a matching ecu and key (rfid chip thats in the key) it wont start.

ive never tried it but i think you can probe the wires going to the injectors and see what they are doing.. i think you have to look for 12v on them sorry thats not much help.

Hi John.

I do have another key and have tried it without success.

I did get another ECU which was supposed to be setup as they wanted my old one (which i had returned) both show the same error code when trying to start, P1108.

Would not it being immobilised result in some kind of error or light showing up? would it even turn over?

Thanks for your input, every suggestion is a help as it can lead to other questions and with luck an answer and could also point others who have a non starter on steps to take, mine does not seem to be an isolated case, there seems not to be one definitive answer to "turning over but not starting"

I think I will have to buy another diagbox as i can't keep getting others to pop round when they have time.

Cheers

hmm aliexpress do the Delphi clone boxes. i have one that works really well.. does your box do live data? if so can you check to see if you have cam and crank sync?

i did not have it on my which was causing it to not start... see here:

My box it dead, the one that was used to get the P1108 error did do live data but I can't keep asking people to pop round and plug their reader in so i will get a new one. There is a guy in Luton on Ebay doing them for £110 with good reviews, saves waiting 3 weeks or so for a shipment from China.

You could be right that there was no sync between cam and crank. I have replaced both sensors so don't think it will be that. the old sensors were not damaged like yours were.

I am currently investigating the wiring loom.

Cheers
