Hi did you get any fix? My car had the same and spent 3 months in the Renault garage. Got it back and now it's out of warranty it has come back

hello
error P049B ' its EGR B valve and the filter that connected to it (and the egr cooler)
try every thing and i mean every thing !!!!!
the only fix to it is to dispart it and clean it with carburator spary and reset the error in the dash
for me it worked 1 year but............it returned this week
good luck for you

Hi,
Had the same problem last week, 2016 plate 56,000 miles.
Renault agent said he cleaned sensor but is to replace both sensors which he said its best to do at same time as fault generally re-occurs otherwise. So come Friday it goes in  and I'm broke again.

Hopefully it will clear problem.

hello
which 2 sensors????
the EGRs or there is sensors to replace or cleaned?????
thanks
