D4164T Engine fault light on after (nearly) running out of fuel

[WilBo]

Hi,
I'm a newby here so appologies if this is covered elsewhere. I recently got a C30 1.6D DRIVe to do the weekly commute. I've probably clocked up about 1k miles in the few weeks since getting it and the car has been great so far and has been a joy to drive.

However, I nearly ran out of fuel the other day and since then the engine light has been on.

Basically, it went like this:
1) went out to the pub the car for a carvery, fuel was a bit low but it was running fine (fuel warning light was on);
2) left the pub, the ca was struggling for power a bit on acceleration, particularly up hills but no warning light;
3) filled the car with diesel (half a tank);
4) left the petrol station and the warning light came on;

I checked the 'secret menu' and I have DTCs in a few places including the Engine Control Module and Info Control Module. However, I don't have a proper DTC scanner to read the individual codes and the Volvo dealer quoted me £138 per hour to diagnose the fault (!!!).

I've ordered a cheap bluetooth DTC scanner to see if I can at least get the generic codes off the ECU, but in the meantime I was just wondering if anyone had any ideas what might be the problem, eg:

1) can running out of fuel cause a DTC (on its own) or is it more likely that it could have caused a knock on problem?
2) If it was just a temporary problem should the engine management light go off at the next start cycle or does it hang around until the code is deleted?

Any comments or suggestions would be welcome.

NB - I have done a few miles since in the hope that it was just a bit of crud that had got into the system hoping it would pull through.

Cheers,

Wil
