Sludge in expansion tank - losing coolant very slowly - ? EGR cooler suspected

has anybody experienced this - I rebuilt the engine 18 months ago and replaced everything except EGR Cooler and turbo

could it be exhaust gas getting into coolant via the EGR cooler - oil cooler was replaced so shouldn’t be the culprit

i gave a new EGR cooler to go on - but it looks a pig to fit now engine is in

Octavia Mk3 1.4 TSI – Droning or Humming Noise Only With A/C On

Santtumh · 16 hours ago16 hr

Car is 2013 Skoda Octavia Mk3 1.4 TSI (CHPA), manual, 118k km driven. Today I noticed an A/C-related droning/humming noise that seems louder than before, but I'm having trouble pinpointing the source. Symptoms: Only occurs when A/C is on. Noise stops immediately when I press the A/C button off (cabin fan still on), Most noticeable at idle and especially after revving the engine and letting RPM drop back to idle. Above roughly 1500 rpm I can't really hear it. Cooling performance is excellen

I have owned my Karoq 140TSI Sportline for a few months now, and there is only one thing that bugs me. I travel on motorways a lot in Australia, where we drive on the left side of the road. When I am driving in the left or middle lane with the ACC operational, I notice that the ACC will match the speed of the vehicle in the next lane over (either the middle or the rightmost). This is very frustrating, as they pose no threat and it is lawful to pass on the inside on a motorway. If I hit the acce

Fans running on after engine stopped

lippy427 · 8 hours ago8 hr

Hi, I have a '2025 Kodiaq purchased March this year. Car first registered last May and was a Skoda vehicle and had covered approx 5000 miles when I bought it. It's been fine all this time except yesterday when I turned the engine off one or more fans continued to run - and they sounded like they were running at top speed. It was only a 15 min journey and the weather wasn't that hot. It did the same again travelling back home. Did wonder if maybe doing a regen, so running hotter, but have been

Intermittent jerks after a few kilometres of driving followed by Error codes

ptapaskar · 1 August, 20251 Aug

Hello All, I recently purchased a 2018 Skoda Kodiaq style Diesel. After about a month of purchase while driving in traffic the vehicle gave intermittent jerks a few times and this stopped. Later after another kilometer or so the Glow plugs and ESC error code started flashing followed by a park assist code. Reverse camera stopped working. The idle RPM went up from 900 to 1200 RPM. However the codes went away and the RPM was back to 900 after stopping and restarting the engine. The mechanic did
