Hello everyone

We have a 2014 Skoda Fabia 105 TDI with 130,000m on the clock.

On a recent trip back from France driving along at about 70mph we suddenly lost power with juddering and the ignition coil flashing. We pulled over, waited a bit and restarted the engine and all was well. We then continued on our way without problem for another 200-250km.

The car had been overdue for its major service (variable intervals) and so the oil was 12,000m old by this time. We have since had it serviced by a local garage but not one we usually know and trust (he had too long a waiting time). No reason to suspect this garage is dodgy and seemed legitimate.

We drove the car yesterday for a relatively long drive on motorway and it felt great but with a longer trip planned we are worried it will fail then instead, something we're keen to avoid.

We have a booking in with our usual trusted mechanic in mid August which I am currently thinking might be the time to get this looked at for a second opinion but wondering if we're being foolish waiting until then?

Wanting to see what you fine folks would do in this situation? Would you just see how it goes and risk a breakdown or would you take it to the (local but not usual) garage to have the injector changed on the basis of this test result and our previous incident?

Thanks for your time, looking forward to see what you think?

It could just be electrical glitch due eg to oxidized connector to injector harness. I'd wait for failure that is more systematic / repeated.

On my wife's Roomster, an injector failed on a trip back from shopping (electrical failure), engine went into limp mode and was shuddering, but other than getting home very slowly, no other harm done. I have replaced actually 2 injectors, as this allowed me to diagnose and eliminate a long term fuel into oil migration issue. Would have replaced only 1 injector otherwise. HTH

It could be a one of due to above. I would wait and also get it scanned with VCDS which may pick up something more detailed. If one is starting to fail it may be that when you replace it and another does the same at some point.

It also depends on the quote for the new injector? I can't see it being cheap so personally I would wait but make sure your covered via AA,RAC etc. Hopefully its a one of

I just wanted to post an update on this. We risked it and it failed. We got a good distance before the injector failed again and we had to be rescued. All in, we left at 10am and returned to the same spot at 1am on the back of a truck. Not great but perhaps a warning to others.
