Fitted the same one myself, easy to fit, not noticed any difference in temp, if heater is taking longer to warm up check the thermostat.

I fitted the inline Renault thermostate mod and that is working fine Chas. To me though, no hot air (exhaust fumes) going through the egr would equal a slower engine heat on starting, as munroman said, which I suspected was the reason for the hot air being a little slower through the heater marix.
I cant complain though as I drove the car with a the original thermostat bein BER and no FBH for 2 years. In the winter I constantly had my thick padded coat on and sometimes a hat

It is/was my understanding that the egr only opens under higher boost or revs, or both. To push the motor to that when it is still cold should not be normal practice.
Mine warms up in about ten minutes at low revs getting out of the driveway and the village. EGR bypassed and reno stat. Goes down to 79 degrees when idling on these cold winter mornings.

Any recommendations for which one as there seem to be a few about.
Do I need to fit a blanking plate to the engine to cover where one of the pipes would go? If I do, again, recommendations please.

Thanks,

Modify your own if you are going down this route it also looks original

tried this just for an experiment still in the shed somewhere as i prefer to clean mine well exchange it every six months as i have two, i put clean one on then clean the one i take off in my own good time.

There are 2 types of EGR input pipes fitted to the M47R
Doesn't seem to be year related either.

One has the water jacket for quick warm up.
Basic type doesn't .

Anyone who's bypassed the former will lose the fast warm up benefits even if they have a good thermostat .

Identification of the water jacket is easy.
Its a stainless steel block with metal inlet and outlet pipes ( all one piece)
A black plastic bleed point is clearly visible too.
I posted pics up few years back on here somewhere!

It also explains why owners report different warm up times on the many Thermostat renewal threads.
