May be, but im sure it is a single plug failure out of all 4 or 5 for 99% case.
Just wait for every start alarm notice, buy single Bosch 0250203001 ( check again ) and replace.
I am not sure whether ecuscan show which one is faulty, but if you screw all out the faulty one has dark end.
You will need 9, mm metric longer socked head. This job is to be done at warm engine only. Actually it is easy to do but be careful. Glow plug is rather weak and if you brake it inside it may cost a lot to extract it. Good luck.
