CDTi Engine failure to start

I swear that while trying to start from the internal battery alone, that there was a ticking noise from the internal fusebox area, in synchronization with every rotation of the engine, maybe a relay dropping out with a momentary drop in battery voltage.

I'm beginning to suspect a dead cell in the battery.
But even so, it should start with a jump start.

All fuses and relays in the engine fusebox have been removed and inspected.
Where is the glow plug relay ?

Dead cell in the battery will show as less than 10 volts across the battery terminals.

The battery after 24 hours charging and not used for at least two hours should be 12.6 volts at least if the battery is in good condition.

I have TOAF talking successfully to the car.
Now if I only knew what I was doing ....

I wonder what the user eject button does ?

Seriously will TOAF indicate a camshaft sensor error ?

Any assistance would be appreciated.

I haven’t used that TOAF program for a long time, obviously because I have a T4, but if memory serves me right once it’s connected to the car and you click the button that says connect you can then click on the engine tab and scan, it should show a fault for a cam sensor as something like camshaft position sensor, or something like that if there is a fault code stored in the system.

However it may bring up a fault code for low fuel pressure supply timing out or something like that, that’s littered in all sorts of ECM’s you can create that fault code just by turning on the ignition and letting the low fuel pressure time out, so don’t be fooled by that fault code, it may also bring up a fault code for glow plug relay, don’t be fooled by that fault code either.

I see these fault codes in our ECM’s routinely, it won’t stop the car starting, unless of course you genuinely have low fuel pressure, low fuel pressure can be tested by simply disconnecting The outlet pipe from the pump to the filter and placing the end of the fuel pipe in a 2 L bottle of Coke that’s empty and turning the ignition to position 2you should see a steady flow of fuel.

One other thing I would suggest you check is a small spade connector on the starter motor, check to make sure there is no corrosion and the contacts are clean

I have 3 errors from TOAF for the engine:

3505 - Glow device
1E00 - CAN - bus
2800 - Supply Voltage

The supply voltage errors are interesting as they indicate 3 errors:
1)Error 1: Apparently the battery voltage was 9.26V, while I was doing 193.45km/hour at odometer 269720km.
2)Error 2: Apparently the battery voltage was 9.37V, while I was doing 185.26km/hour at odometer 269720km.
3)Error 3: Apparently the battery voltage was 9.14V, while I was doing 185.26km/hour at odometer 269720km.

All while starting the engine, with the bonnet up, door open , & with the transmission in Park !

I think I need a drink !

Amazing doesn't quite cover it !

(BTW I do have a FBH fitted)

Glow device- not relevant
Can-bus - have you got a FBH fitted
Supply Voltage- what is the voltage at the battery posts with the key in position 2?

it is most likely to be a break or partial break in the yellow wire with a red tracer between fuse 2 engine compartment fusebox, and pins one and eight of the most inboard connection of the ECM connector CO603

Brian, you might be a genius.

At a guess, some kind of power supply wire for the K-bus or the CAN-bus ???

Any chance of a diagram ?

[MarkS]

The CAN-bus errors are as follows:

Errors count 9
Sporadic error

Error 1:
Engine speed 0rpm
Supply voltage 11.92 V
Injection volume 14.85mm^3
Driving speed 0km/h
Current odometer 265780km

Error 2:
Engine speed 0rpm
Supply voltage 15.85V !!!!
Injection volume 13.31mm^3
Driving speed 39.92km/h
Current odometer 269700km
Receive fault transmission control (EGS)
Reception fault ASC
Instrument-cluster reception fault (INSTR3)
Instrument-cluster reception fault (INSTR2)
Reception fault from transmission (TXU1)
Reception fault from ASC3
CAN-bus shutoff

Error 3:
Engine speed 0rpm
Supply voltage 17.47V !!!!
Injection volume 62.47mm^3
Driving speed 0km/h
Current odometer 269720km
Receive fault transmission control (EGS)
Reception fault ASC
Instrument-cluster reception fault (INSTR3)
Instrument-cluster reception fault (INSTR2)
Reception fault from transmission (TXU1)
Reception fault from ASC3
CAN-bus shutoff

Or summat similar

PS I have occasionally suffered with ERR on the trip 1 display.
It's all starting to tie up.

Needs a bit of orange wire

I'll see if I can find some wet bailer twine ??? :-}
