Hi guys.
My EML came on today randomly.
i have ran VCDS on it and have got the following code and i am just want to make sure that what i have worked out is correct and to find out what is the next/best way to proceed with this - as in DIY fox or if its better to go into a garage?
the data is as follows:
1 Fault Found:
16932 - Control Circuit for Reductant Heating 1
P20BC 00 [172] - Short to Plus
MIL ON - Intermittent - Confirmed - Tested Since Memory Clear

(i can provide full scan details if required)
from what i have found it sounds like my adblue heater No. 1 has failed.
the help im needing with is:
1. would i be correct in saying that this is inside the tank, if so do i need to remove tank etc to change it?
2. has any one got any help or advice in doing this DIY style?
thanks in advance.
Tom
