Creator OBD2 reads: 00, 001, 48, 73 No Found! - Is this a Fault Code?

[diegoX]

CEL came out and these are the codes that came out using the Creator C310 OBD2. Are these numbers fault codes in the first place? Any information what these are? Tried to contact Creator to no avail, their email support provided in the instruction booklet doesn't exist. Google doesn't have the answer. CEL has been reset several times but it returns after 100 miles. Generic OBD2 reads p2457. Thermostat and water pump are all new.
Thanks

Since you only rant the codes, but do not even list the model and year - what kind of support do you expect.

My guess is you own a diesel....ja or nein?

I dont know about creator, but p2457 seems like a reasonable and actionable code....

No cracks found on the EGR Coolant. No idea how to pinpoint broken sensors. I guess I'm just gonna have to bring it to the pros. Thanks!

BMW fault: 4873 Exhaust gas recirculation cooling, plausibility - fault is due to an error in monitoring EGR cooler bypass flap.
1. Check the vacuum supply to the exhaust gas recirculation cooler bypass flap (vacuum lines and changeover valve).

2. If the vacuum supply is OK:

Replace the exhaust gas recirculation cooler (throttle return spring of bypass flap may be faulty).

Fantastic! I'll check on it. Thanks!

I have the 2010 35d as well and now have the same fault code. I do not see any soot or cracks on the EGR cooler. Excuse my ignorance but how do you perform #1 - Check the vacuum supply to the exhaust gas recirculation cooler bypass flap (vacuum lines and changeover valve). Can anyone direct me to the part # to be replaced on realoem site?

Thanks guys
