The four digit code doesn't make any difference if you can clear codes, I guess this normally as it's only required on fancy models with extra computers, but you don't have that on a 306. What is important is that you're selecting RHY EDC15C2.
You need the ignition on two clicks without the engine running to clear codes. I've had communication errors before and they were due to very flat batteries. Try charging the battery or putting jumpers on whilst you're connected to it.
Once you've cleared the codes, go for a drive and read them again and then we can advise what you need to do.
