Hello and welcome to the forum.
We do have a few Renault Techs on the site,and they should be able to say if this is common or not.The only thing I have experience like with is when a primary pump(usually in the tank) breaks up and sends metal filings through the system to the high pressure pump.Because of the final pressures involved the high pressure pump is very sensitive to any minute pieces of metal,and the same filings can damage injectors too.I've never had it on a Renault dCi yet,but Peugeot HDi's definately suffer from this problem.
I'd rather push my Alfa than drive a BMW....
Currently in Lagdti's garage:
2003 Alfa Romeo 156 2.4 JTD Sportwagen (estate to you and me!), 2004 BMW 330d Touring in many,many pieces, 2002 Alfa Romeo 147 2.0TS Lusso soon to also be in many pieces.....
