EGR Error codes P023B and P24A9 [Resolved]

[tyronmapp]

P24A9 suggests a power interrupt. Does the fault clear?

It does clear but comes back on sometimes straight away and sometimes after a while

Faulty wiring perhaps?

For the P164B 00 check this

the error codes which i was getting were caused by a wire which had rubbed through just above the gearbox this was blowing the fuse

Hi, can any one help?
I have a P023B charge air cooler pump control circuit low and
P24A9 EGR cooler coolant control circuit low flow.
it seems to have appeared a couple of weeks after the cam belt was changed and the coolant was topped up.
Any ideas please.
cheers,
pete

Hello brother ,my t6 today is same with you the code p023B and p24A9.
I just finished referring to your paper, and I also found that fuse #27 in the fuse box was blown. I'm very grateful for your sharing. Thank you.

Hello Shaw
I'm having the same problem as you. I've tried replacing the fuse, but it still blows. I've checked the wiring of both water pumps, and it looks neat. I've also tried unplugging both water pumps, but the fuse still blows. So, could you please tell me where you found the short circuit? Thank you.

Could it be a problem with the temperature sensor?
