I have the usual "Fault in Fuel Injection System" error on our 52 Plate Laguna Sportshatch.

Got a code reader which came up with 19 errors

P0032 01/19
P0032 02/19
P0711 Pd 03/19
N/A 04/19 - 19/19

Anyone any ideas.

The codes seem to be generic rather than Renault specific. If the code reader isn't compatible with Renaults it can throw up erroneous meaningless codes.
Also when was the ECU cleared of fault codes. Those current could be very old. Try clearing them and see what new ones appear.

See the link below for a list of generic codes.

Thanks for the reply, it wasn't a Renault specific reader, I can't seem to find one for reasonable cost. This was one a friend of mine has & I'd just read the codes on a Polo & successfully erased them. When plugged into the Lag it seemed to read them with the results above, but it wouldn't erase them, so possibly they are not valid. But the link was interesting pointing to the fact it could be an O2 sensor, which would make some sense.

In my experience it is rare for a diesel engine to show an oxygen sensor fault.

Apat from the warning light is the engine running O.K.?

Obviously the code reader ain't Renault compliant so it may not be wise to act on what it finds.

Yes engine runs nicely until the error light comes on, switch it off & re-start, light goes off & all is well again. It also comes on at the same point each day about 2 miles from my house. I've changed the glow plugs to no avail.
