I am getting the error code P20B9 and the engine light is on. The code relates to the reductant heater fault. Where is the heater situated and is it powered by a fuse. AdBlue freezes at -11 so is ok at the moment.

Thanks

Exhaust gas getting into the coolant
Skoda Octavia Mk3 (2013 - 2020)

Exhaust gas getting into the coolant

Marski · 30 June30 Jun

Hi, I've recently sold my MK2 and bought a MK3. I'm having issues with the exhaust gas getting into the coolant. I need to find out what is causing this. Is it likely to be the EGR or something more serious like a blown head gasket or a crack in the block? I've only had this car for 5 weeks so am looking to approach the dealer I bought it from. They only gave a 30 day warranty. They already had it in for a week and were supposed to repair this but they haven't done it.

Stage 2 saga update- good, bad and ugly

Little update since i posted about my Superb 280 going stage 2 back in may. I have questioned the high torque figure ( 618nm) with the tuner and was assured that it's a safe map, ok i left it at that. Three days after remap, car starts burning oil without even being pushed hard. So i switched to thicker 5w40 Castrol Edge ( issue rectified) Week later i pinned it from traffic lights and car cut power after 5000rpm. Gear changes felt really rough and jerky. Questioned it with the tuner, got nowher

Creaking front-end

History is that since the coilovers were done, the front-left top mount has aways creaked on turning; classic top mount sound of juddering movement. I've tried rotating the spring a little in case that's a difference but I need to do try some more just to make sure I haven't forgotten anything. In the meantime, the front right has developed a creak which is different. It's a heavier creaky rubber feel to it which is triggered on minor movement/weight shift. Going over speedbumps obviously makes

1.2 TSI loss of power
Skoda Octavia Mk2 (2004 - 2013)

1.2 TSI loss of power

Papez · 2 July2 Jul

Hi, hopefully you won't mind my question here - I don't have an Octavia, but its close relative from a Spanish brand. But mechanically, they are same. Anyway, I have a 77kW CBZB. It worked flawlessly for the year I own the car, but when this summer started, I noticed occasional loss of power. It only happens in hot weather (around 30 degrees and up) with AC on. In most cases, it happened when I wanted to accelerate after mild climbing at lower gear at ~2000RPM. It feels almost like a limp mode

Hi everyone, I’m hoping someone here has come across this exact issue, because after 7 months and multiple visits, neither my dealer nor Škoda’s technical support has been able to identify the cause. Car: Škoda Superb Sportline, 2021, 200kW Problem: When braking, the side sensors intermittently trigger a warning that there is an obstacle very close to the car — even though there is nothing there. It happens sporadically (not every time I brake) What has already been done (all without success):
