Engine cut out and wont start now.

[rudeboyraz]

Hi so my T6 died on me whilst driving it. No prior warning, just konked out after the coil light flashed a couple of times and message to start manually on instrument cluster and now won't start I've posted the fault codes that come up after I've cleared the historical ones.

 

[mmi]

Does it crank? Or cranks but doesn't start?
P0690 00 suggests the ECU is missing a power feed - have you checked the fuses supplying ECU?

Thank for the reply yes it cranks but doesn't fire up. It will run on easy start for second or two so it seems like a fueling issue.

 

[rudeboyraz]

Just an update been told its a 5 volt issue something that's shorting or malfunctioning suggested looking at the wiring diagram a try to trace it.

 

[mmi]

Did you check fuses in fuse holder B?

 

[rudeboyraz]

Did you check fuses in fuse holder B?

That's good shot I'll try them tomorrow

 

[rudeboyraz]

Checked all fuses and they're all good, I've got access to an Autel scanner if there's any readings I should be looking at?

 

[mmi]

Well, we don't know what engine you have - the engine code would be helpful (something like CAAC, CXGB, CXHA...)

Anyways, can you read live data for

IDE00182 Camshaft adaptation intake bank 1: phase position​

Can you do similar measurement as below to verify that fuel pressure builds up and injectors do fire:

Won’t start [Resolved]

T6 204 diesel. Van was used on a long drive and then a trip to the shops. It was left 5 mins and then wouldn’t start. Turns over but doesn’t fire. no fault codes. There was a slight burning smell when I parked up and it looks as if the front egr pipe has a crack, rear one has already been...

It's the 150bhp cxha engine I believe I'm going to try and get my hands on a VCDS.

 

[rudeboyraz]

Anyone know where i can get VCDS download link it wont let me connect to rosstech

 

[rudeboyraz]

Or anybody in and around Birmingham that can help me?

I’m not expert on VCDS but your battery voltage is showing 7.5V, that’s insufficient for the control modules to operate.

Hi, I think DXX might be onto something. I bought my VCDS HEX-CAN OBD tool from Ross-Tech and they sent out the OBD tool, a disc and a link to the software.

So the engine is cranking (Engine status=Engine start) but there is no fuel pressure?

Here a log whist cranking

And here is of the codes before I cleared them

Here a log whist cranking

Looks like the air filter box was not connected (no change in air mass) - anyways doesn't prevent engine starting.
Engine was cranking fairly well. Lift pump was commanded to activate.
However, there was no fuel pressure - ECU did not even to try to fire the injectors (Main injection: duration of activation = 0).

Green=GOOD
Red=not good.

What does VCDS report for
IDE00182 Camshaft adaptation intake bank 1: phase position ?
