It could be the chain but it can be difficult to tell, the only way to be certain is to take out the chain and compare it with a new one, which is a major £2k plus job. Have the garage checked measuring blocks 208 and 208 in the engine module, a reading of 9 or over in either one is an indication of stretching. Can you hear any rattling from the gearbox side?
Stuck VVT's or a faulty tensioner can cause similar problems, even a faulty coilpack can sound terminal.
My money is on the chain though.
