P2 V70 TDI cutting out
Evening
This afternoon, my P2 V70 TDI cut-out just as I was leaving work. A warning message came up saying that I should drive slowly and it needed an urgent service. I started it up again but it would cut-out whenever the revs increased about ~1400rpm. I tried bleeding off a little fuel from the filter, in case it was contaminated with water but no luck so far. In the end I limped back to the carpark at an idle. Whenever it stalls, I'm able to start it without too much trouble, provided that I turn the key all the way back before trying again. Does anyone have any suggestions for my to try, as it's currently stuck at work and I'm less able than normal to tinker. It is showing as having less than a 1/4 tank of fuel (but no light on) so I could try topping up with a few litres. I could also try replacing the fuel filter. All the best, Bill

Veg-free
I'd be inclined to agree, but this one hasn't seen a drop of the stuff!
Sadly my veg oil days are behind me and I haven't done the conversion for this car, even though it has the same engine as previous ones. I do miss that 'free motoring' feel and the occasional whiff of sweet veg oil exhaust, but it did result in increased maintenance/issues! When the engine cuts out (current problem on non-veg V70), it is very abrupt rather than faltering, which I would tend to associate with fuel starvation... I may be incorrect though! If anyone has any suggestions then all thoughts welcome (well, almost all thoughts - this is the internet after all!) Best regards, Bill

Could this be an electrical issue? Might be worth checking the connections to the injection pump and associated wiring, assuming you haven't done this already.

I would start with the easy item first - change the fuel Filter.
The in tank fuel Pump on my V70 Died, apparently it's quite rare but can happen. You should be able to hear the electric motor priming the fuel when you switch the Ignition on for about 10 seconds or so - another easy check to do. Next, try and get the codes read. Good Luck

Thanks
It is still stuck in a car park at work but I did start it up again today after reseating some of the relays. It started well but still had the check engine light. I tried revving it, expecting it to cut-out at 1400rpm again but this time it seemed fine. I drove it around the carpark, but then it abruptly stalled again with the same 'drive slowly warning'. It then started up okay but cut-out again in similar circumstances. When working, it sounded fine and didn't seem limp or fuel-starved but good plan to do the filter anyway. I'll also check more of the fuses and contacts, just in case. Still need to get it home though! Best regards, Bill

Update
Good afternoon
I have an update... Having arranged for a friend to follow me home one evening, with tow rope at the ready for a speedy recovery, I made it back without any issues. Last week I finally bought a faux-Dice (actually a Mongoose) interface and have been busy getting Vida working, based upon the guidance on VolvoDiag.com. After a little fiddling about, I was delighted to get it working and be able to read codes and make minor mods to some systems. The codes thrown-up appear to relate to the engine speed sensor. When a faulty signal was detected, and the conditions were correct for it to be 'potentially believable', the engine was cut. This all sounds plausible, and I guess that it's an intermittent fault. Having established that it's probably not a major mechanical issue, I've taken it out again for another test drive and so far, no problems. I've now got to find the sensor and see if it's worth replacing it. I was also going to have a go with the pump timing, but I think it best to deal with that in a different thread as I've not been able to find the answer to the question I have in the posts I've already looked at. Thanks everyone for your help, Best regards Bill
