Five years ago I got a PO130 code when the car was running rough so I
replaced the bank 1 sensor 1.....yesterday I got the engine management
light and got a PO135 code for the sensor ... so the heater in the
sensor has gone....car is running fine I assume this will be an MOT
failure even though the car is running fine.....why the hell do they fit
heaters to these sensors just to gain some minor emissions crap until
the engine has heated up ?...

update... cancelled the fault code and the engine management light
hasn't come back on...fingers crossed it stays off.....

It's not unusual to get erroneous error codes which don't come back once
cleared. I had quite a few on my previous car - Volvo V70 - some of
which looked serious, but never were.

It can be a nuisance if the ECU switches to 'get you home' mode and the
car then does not run properly. Used to happen to my wife's Golf. By the
time you got to a VW garage the fault had cleared.

Our diesel Fiesta is not that clever. However, engine torque is much
reduced while the filter is being cleaned. On long trips it would remain
in this mode unless the engine is switched off and back on!

With careful use of the clutch, this can be done on the move:-)

Common one on my last car was the crank position sensor - a hall effect
type - having an intermittent fault. Likely something akin to a dry joint.
When that happened, the ECU got its tach signal from the cam sensor only
and went to limp home mode. Fixed timing for ignition and injection. But
would often clear itself after the engine cooled down. Luckily, the fault
code was stored. That car had 3 CPS in the 15 or so years I owned it.

I've had a warning about my AdBlue heater for two years now. I believe the heater is broken, but since the freezing temp of AdBlue is -11C, I can live with that. My garage reset the code every time when they do an MoT.

that is exactly what happened with the crankshaft sensor on my merc C180T

When I had a coil pack fail on a car I had fault codes completely
unrelated to my car (diesel related faults on a petrol car).
