I also had the injection warning and was quoted some very high prices to rectify the problem, even after paying for a diagnostic was told it was the fourth injector. Car was running well, so after reading comments on here I had it serviced at my local independent garage and requested glow plugs to be changed, and 2 were blown, and the warning has now gone.

I wrote the comment about glowplugs causing this error in my Grand Scenic review. Unfortunately "Check Injection" is a generic fuel system error message covering a whole list of faults from trivial to terminal. You need the Renault CLIP diagnostic system to read the fault codes to determine where the fault is, which of course is not available to Joe Public. The good news however, is that it is possible to pinpoint or eliminate glowplugs by doing the following:

Start the engine from cold, and take it on a drive to get it completely up to operating temperature. Once you have done this, pull over somewhere safe, switch off the engine and ignition.

Restart the engine immediately. If your "Check injection" message is a glowplug fault, it will have cleared itself (this is only temporary - it will come back next time the engine cools, but this confirms the diagnosis). Buy a set of glowplugs and you're sorted. If it still says "Check Injection" you have another fault elsewhere.

These are generally horrible cars to work on, but in fairness, changing glowplugs on these (the 1.9 at least - never worked on a 1.5) is no harder than changing spark plugs on most petrol engines. Easily accessible, and the leads push on rather than making you deal with those fiddly 6mm nuts. I did all four in well under 30 minutes.

If you have the key card in the slot and switch the engine on, you can release the handbrake, so maybe that is how he did it.
