An update. Seemed to improve a bit after the garage visit. The big change was a couple of decent blasts along the motorway. Yesterday I even managed 50mpg (according to CPU) on a 70 mile journey. I think with all this lockdown nonsense the car just hasn't been driven enough. This is certainly the case for the stop/start, I don't think the battery was getting topped up enough between starts so the stop/start was quite rightly deactivating. Traffic has been increasing with the easing of lockdown so that may have affected it too. To answer some of the suggestions: Airfilter was fine. Petrol 'seemed' fine (no other local complaints) Brakes ok, this was something I asked the garage to specifically check but also checked myself (none were overheating after a short drive). Computers ok (Can't even find where to change it into metric! But is on imperial). Thanks all for your suggestions/advice etc. Now to the Fabia VRS forum to sort the little car out!

Think it was ex management. I’ll be ringing the guys I bought it from to get them to add the sales service they said they would do the the record. Hoping it’s just a dodgy fill up so I’ll run it down then brim it. I’ll check the air filter. Thanks roottoot.

The mpg I’ve stated is from the onboard computer. I’ll be doing my own assessment next. Fuel is 95. It’s only ever had 95. Filled in a BP garage that we haven’t used before. Registered nov ‘19, owned since aug’20. 9500 miles (3500 by me) The service light has never come on but the garage said the electronic log indicates it hasn’t been serviced, says it is due in May ‘22!

Fuel economy on my Superb Sportline has dropped from about 32mpg to about 18mpg for the same journey overnight. It seems to have also coincided with filling up with petrol (coincidence?). Also, the start stop is no longer kicking in. Just got back from the dealer who says nothing is wrong except the battery was a bit low so they charged it up and start/stop worked for them. Journey home and the start/stop didn’t kick in once and the fuel economy was still shocking. Anyone got any experience of a similar problem? The people you speak to at a dealership are sales people, not the technicians. I just got accused of changing my driving style overnight.
