Thanks nta16 and rum4mo 👍 The car has been serviced annually, with proper bits (checked) and it’s in for another one now at the same time as the checkover. They’ll do a live check tomorrow, but so far they say it’s a blank on the sensors and readings. Faulty sensors, EPC came to mind, as did fuel quality (French supermarket and sometimes E10) and coking. But the starting issue hasn’t been consistent or regular. It gets an Italian job up an Alp once a month… I’ll give the injector fluid a go. I may have overfilled oil marginally I think recently, a dipstick check was 2/3 but I didn’t realise the camber (towards the gearbox end) at that spot, so a cautious 200 ml top up might have run slightly over.

‘Afternoon all. LHD Fabia Mk3 1.2 TSi Combi, 110 ps, silver. 2016, purchased end 2019 with low mileage. Manual box. Now 117,000 kms on the clock. Workhorse, pack carrier and Swiss knife of a car. May have to trade it, reluctantly, with a move later.

Afternoon all. Sharing a recent intermittent issue on my Fabia Mk3 2016 1.2 TSi. 117000 kms, appealing to your experience. Garage is investigating but no fault codes are showing up. On start-up first thing in the day, the engine splutters or hesitates for a handful of seconds, sometimes accompanied by significant engine rocking (the alarming bit). Symptom swiftly disappears and the engine goes back to normal with or without a prod on the accelerator pedal. No unusual noises like knocking. Later starts in the day are perfectly smooth and normal. On one iffy start while under cover I noticed a smell of petrol. In old days (…) some of the symptoms would remind me of a flooded carburettor. Intermittent issue, happened about 5 times in the past few weeks. Seems to be only on warm mornings (approx. 20 degrees C). It’s not the brief tappety tick or engine grumble note and mild jerkiness while pulling away. No other signs, no warning lights, engine pulls and idles smoothly, fuel consumption fine, oil seemingly ok, battery good, spark plugs a year old. Thoughts: Have seen this thread, was struck by the ‘bounce, etc’ (!) and temperature, but it doesn’t last that long and hasn’t happened before in 6 years of use. The note avoids specifying what conditions. Could a slight over-topup of oil (possible) trigger this?: https://www.briskoda.net/forums/topic/504258-a-tsb-from-skoda-on-cold-start-behaviour-with-12-tsis-something-that-dealership-employees-should-be-able-to-explain-to-customers/ Another thought was a worn timing belt tensioner? Thanks.
