'Fault codes' thread closedown

That's a lotta labour to unplug the sensor, undo the 10mm bolt holding it in, and replace it

Agreed, but maybe they did some diagnostics first, or some other checks?

Yes........................I had an Omega (2.0 litre auto) for 2.5 years. It was the most unreliable car I ever owned. Oxygen sensor failed twice, crankshaft sensor, water pump, alternator, brake pad wear indicator, cd player, differential oil seal, drive-belt pulleys, etc. etc. Frankly it would be simpler to list what didn't fail!!

Yes,there was some diagnostic time involved, and from the location of the sensor, it was not quite as simple as "just undoing ..." etc, I'm sure! As for reliability, this is the first real problem I've had with the car. Mind you, it's really an Opel in Vauxhall livery, so that may have something to do with it ..... :o)

All cars have faults, the more complicated cars then obviously the more to fail. Good design obviously helps but the description of problems could just as easily have been a well serviced rover 800 I once had (80k, company maintaince, my dads previous one owner but head gasket, power sterring, airbag, abs etc etc and that was only in about 2 years). So maybe it is bad design after all :o) Became a bug bear, but no getting away from them being good cars, well at least fun or worthwhile cars to many people anyway. Take the MGs they can be unreliable but worth the haslle? You choose the effort you want to spend on it. Personally I am happy with my Fabia from new because I havent had to put up with any real problems and its also been inexpensive on all fronts. Pays your money takes your choice etc etc. Maybe you should have bailed the car earlier if it seemed like a lot of problems to you. (But why does it always seem after you have spent money on a car you feel like you invested in it...I think this is part of the problem - cars need constant attention and spending money on one problem does not necessarily forfeit all others from creeping up!).

Is it that easy? On my BMW, you first have to remove the fan for access, and then the plug is a bit of a pain. So about 1/2 hr labour wouldn't be unreasonable, including a check afterwards.
