Hello,



My troublesome 2000 Golf TDI PD (115bhp) has the following DTC:


17664: Engine Coolant Temp.Circ Open/Short to B+

Can anyone explain this code in a little more detail? What are the common causes of this fault?



Many thanks for your help,


Glen.

99% of the time it's the ECT being faulty.

Thanks for the reply. I have re-seated the connection and reset the fault flag. Fingers crossed that's done the trick. Thanks again.
