VW Crafter 2008 BJL-Engine long start time

Hi,

A Friend has 2 VW Crafter, one has only 30 000 km Mileage, the other
has about 80 000km on it.

BOTH Cars are with same BJL Engine.
BOTH Cars have the exact same Problem....long starting time in the morning.
He started the Car today once before calling, so the Problem was not 100%,
but on first start and if colder it really takes long he states.
BOTH Cars run just fine as soon as the are running - Max Power no problem.

No trouble codes in either one stored.

All Temp-sensors show a difference from about 3 Degrees C to another - fine.

The VW Dealer had a look at the older one about 3 Months ago,
and changed the EGR Valve, the Pressuresensor for DPF, and the Crankshaft Sensor.
Wrote a big bill, and no change Now the second one has the same Problem...

I looked at the one with only 30k on it.
Red is Railpressure Sensor Signal
Green ist Rail Pressure Regulator on end of Rail
Blue is the Signal from the Camshaft Sensor.

If i look at this right, the Pump has no Problems, about 1 sec from nothing to
more than it needs for runing at idle.

But looking and messuring the CAM Sensor, i would say it cranks to slow,
i think at this rpm, the ECU will not start.Sounded not fast to the ear.

Both Cars got new Batterys put in, this one about 1 Year ago.
The other about 2 Years ago.

I only had a 15 Min to look, because he had to leave.
But if someone has anything i should scope, i will do that the next days.
I think Crank-Sensor and Starter power and current would be next ?

Thx Chris

Diesel long Crank & Start

1. CKP for RPM, 2. FRP for Common Rail Issues, 3. Starter Current for RPM & Interference etc, 4. Injector 1 Current or Command if no Current registered - Codes Cleared and scope running !!! . Attenuator plus H Voltage PPE at all times.

Then all the above again sacrificing one Channel for Battery Voltage at its lowest during crank.

And how many points would I get for guessing that they get their Diesel Fuel from the same supermarket/ budget option provider more often than not ???

Will see that i get a chance next week.
Good messuring points...

I don´t think you would get many points at all.
Normally these to cars don´t get to see each other
for most of the year because of 50km between the
parking places. I Maybe if a job requires both, then
they have the chance of getting fuel at the same station.

I don´t think you would get many points at all.

My point being that that even at 80,000km (50,000 miles) these vehicles are like new and should be error free. I am guessing that they are using cheap supermarket fuel contributing to these premature failures ?

I Have a 2011 Renault Traffic Van M9R done 172,000 miles (280,000km) in 5 years trouble free ish. I expect it do that all over again before I throw it away.
