Hi if I try and start it on its own battery which is at 12.45 v it drops to 10.97 I ve just give it a sniff of easy start and it will fire on the easy start but no fuel being injected into the cylinder cam belts found could compression test but I think it’s electrical

removed the plug on injector number one and turned it over with a good volt meter connected to the injector plug only reading about .2 volts
Wrong way to do it !!

As soon as you unplug the Injector the ECU will detect that and cut supply / voltage from that injector.

Dropping to 10v is acceptable.

The fact that it will run on Easy Start is a good sign of Mechanical integrity !! Sort of !!


I would now be Scoping the Crank Sensor and Injectors !!

Graph the 3 I asked you for please - Especially RPM !!

Hi, I am struggling to load any graphs or photos but I have managed to record:

IN_Injection_speed_injector(0) Peak: 235.8/min
IN_Injection_speed_injector(1). Peak:236.8/min
IN_Injection_speed_injector(2). Peak:236.5/min
IN_Injection_speed_injector(3). Peak:237.8/min

I can appreciate that you are trying !!

There is a good reason why I want to see Engine RPM, Rail Pressure (actual) & Battery Voltage on a Graph -That reason is to help you get your van started !!

However if you want my help then I would like you try harder, keep trying until you get it right. Please note that no one was born an Expert on VCDS - We all learnt except @Uwe :cool::cool:

Perhaps some one here can point you to a good Video that you can study.

Hi,
please find information asked for. Battery starting to go flat so has been put on charge. Please let me know if you need anything else.
Well &uck my old boots !!
You did a better job of that then I could do !!

That RPM is a little on the low side - I would like to see ~ 280rpm.

However if you were to squirt easy start before you crank it then that would raise the rpm well above that and mask any low rpm issue, if you have one, theoretically it would start and run.

Try that please, and yes I note that you have run it on easy start - Worth a shot but I do think your problem is elsewhere.

Crank Sensor was my other suspect but then we do have a healthy RPM reading !!


We are now left with

Address 01: Engine (J623-DAUA) Labels:. 04L-907-309-V2.clb

2 Faults Found:
27277 - System Voltage
P0562 00 [00100011] - Too Low

Time for a wiring diagram from Erwin, a 21w bulb and a Voltmeter (if you do not have a scope). Test the Powers and Grounds at Engine ECU whilst cranking !!

Update: Still no start! Had Engine control module sent away and tested and no issues found all working well. Back pinned wiring to the ecu and cannot find any low voltage and replaced the Alternator. Can the Body Control module prevent the engine from starting?
Please fine below the most recent scan with fault codes. Looking for any help as the van is stuck on an island.
