My s-in-law had this exact same problem (but in a 2007 Vectra). Turned out to be blocked drain from between windscreen & engine bulkhead. Easy fix.

If the ABS light is also on then the passenger side sensor is capput. This requires a new hub unit as sensor is not available separately. Just had similar problems (2003 1.6l auto) & a replacement hub magically cured it! Hub £45 off ebay whith 2 year guarantee (don't be tempted by cheaper ones). Test the hub with a multi-meter: should read 1 to 1.5 ohms across terminals stationary, flicking up to higher amount when rotated as sensor passes peaks on internal toothed wheel. Good luck!

I appreciate this is an old post, but: I have a 2023 1.6 auto, 72k miles. Wish I was getting anywhere near that consumption, I've owned it 14 years & have only managed 38mpg on long m/ way runs doing steady 60mph. Normal running about it's 33/ 35mpg. Compared to 1.4l 16v I had before (38/43.mpg) I didn't think it too excessive. I'm a fairly steady driver eg. I used to get 43/ 58 from my 1993 1.6l cavalier! (Wish I'd still got it: utterly reliable & almost faultless). What's your secret LOL?
