Lamda fault codes ??? Help

Hi all, I have a 02 megane 1.4 thats being a pain.


Originally it was showing two fault codes = both 02 sensors heater malfunction, Also the car was stuttering now and again and would bring all the ingnition lights on briefly.

Anyway both 02 sensors changed and the cars running much better and smoother.

Problem is its still givinng me fault P0135 02 sensor bank 1,heater malfunction.

Anybody got ant suggestions or answers please?

Please don't post your problem in more than section.I know you maybe desperate for an answer,but it causes confusion.

Hopefully a moderator will see this and merge the two threads.

Thanks for you co-operation.:)

I had a similar string of lambda / 02 faults like that once - turned out to be the wires to the probe had melted against the exhaust causing an intermittant short circuit...
Might be worth checking...
