hello, it's been a long time, but nevertheless I'll ask - what kind of resistor and where did you add to eliminate the e71 error?
Thanks for the info.I have now found out that this fault is a spike to the key switch relay and by fitting resister in the feed in wire it stops the spike and now all working well.
Regards support.
E71 is low out unknown and very difficult to track down. There are several low outputs from the ATC and they are not separated by diagnostics. Look at solenoids, contactors, horn, flashing light,relays. As I said very hard to track down the short circuit unless something stops working
