EDC16U1 - No Check Engine light

[Automed]

At this point there is no start at all bt I understand that when there is jst a immo problem it will start and cut after about 1second I had these symptoms with other VW before.
But at this stage I have the engine swinging but no start .
No current to Glow plug and injector
Crank sensor good and have pulse and all power same for cam sensor.

If I squirt some starting fluid in intake while cranking the van starts but cuts when fluid runs out

I have tried a golf 5 ECU before this ECU that I have now . We did immo of on the golf 5 ECU and vehicle started right up, but that ECU did not last a week then vehicle switched of while running . The golf 5 ECU I tried because it was edc16u1 "CP" . I'm not sure why this failed but I purchased this from a scrapyard. But after the vehicle shut down I sent this ECU for testing and then they got back to me saying we need to do injector drivers in the ECU

The original type ECU for this caddy is EDC16u1 "GP" this type ECU came originally with the vehicle .
And this is the type I have now and trying to get working on vehicle.

I have only tried the golf 5 type ECU as I was failing to find the "GP" for a long time

post from your original ecu bosch numbers, to get the exchange ecus that you can use....

Mate post the ecu bosch numbers, if you can connect with diagnostic that it doesn't mean this ecu is exchangeble with your ori...

Man, the Bosch number on the original ECU and the ECU you want to put. They tell you what hardware configuration is in that ECU.
Those in the form 0 281 xxx xxx.
You either have an incompatible ECU or you have another problem on the car.
That's why I asked you about these Bosch numbers.
Because as our colleague Panathaole said, in case you had a problem ONLY immo, the engine must start and then stop.

Firstly thank you guys so much for been so responsive.

How do I get this ECU numbers you request . Is it on the label on the ECU or do I need open a certain file with diagnostics?

[Automed]

Hi I Bosch number on original ECU and the replacement ECU I have is 0 281 012 168 they both match.

[EDC16U1]

0281012168 03G906016GP comes with at least two SW update versions 6250 and 7001. If their SW are not the same this might be the source of your problem.

Hi.
This might sound like the next check I need to confirm. Please advise how I may confirm this information, or what steps shud I take next

[EDC16U1]

You can check it on ECU's label. But if ECU has been updated by dealer while servicing, or by previous owner etc. this would be incorrect as label still will have old update version number on it.
or VCDS which I use it, can show ECU details. Do an autocan with VCDS then on autoscan page check '01 Engine' it will show ECU details i.e
Part no SW: 03G906016GP HW: 0281012168
Component: .................6250 (or 7001)
Also, For sure any flashing or programming tools MPPS, VCP, KESS, KTAG, BDM etc all show ECU details.

[Automed]
