Hi lads and lasses.
I have a 2019 superb 2.0tdi that keeps going into limp. The dtc I get is p040200. I've replaced high pressure egr and low pressure egr and cooler. Tried a maf sensor. Done a air leak test and still no good. Anyone had this fault before?
Thanks

Might also be worth posting in the relevant Superb forum if you haven't already done so.

Sorry mate I'm new here. How do I do that 😂

I’ve moved it for you 👍

On the turbo check the actuator works properly and you may have a dirty/sticky VNT mechanism.

What sort of mileage/driving style does the car get?

Tried a turbo actuator sensor. The vnt rod moves free enough. It's booked in at skoda Monday 🤞🏻

Coding the mode select option on Octavia MK4 pre-facelift

386ka · 16 minutes ago16 min

Is there an option to code the mode select option to pre-FL Octavia MK4 with 1.5 TSI engine? There isn't a button, obviously, since the equipment wasn't selected at purchase. However, AFAIK, you can select and customize the driving mode through the infotainment as well. Also, does the mode selection actually bring any noticeable effect on the engine responsiveness and steering feel? Thanks!

Does the Skoda Superb EA888 Gen 3 (CHHB) use dual injection or only direct injection?

username8888 · 14 minutes ago14 min

Hi, I'm looking at a 72k mile Skoda Superb 65 plate, hopefully lots of motorway miles. It looks good, my main concerns being the lack of dsg oil change & potential for carbon build up due to direct injection. I currently have a mk6 Golf GTI (EA888 Gen 1) which didn't support dual injection & bit me when the carbon build up & clogged injectors caused a flooded cylinder. I've tried to research this but I'm getting conflicting information around this engine & I wasn't sure if s

Kodiaq iv (2024) - Departure planner

DaveSuperb · 19 August, 20241 yr

Hey, Just got delivery of a new 2024 Kodiaq iv. All good but there doesn't seem to be a departure planner (for setting charging times) in the Skoda Connect App. I had a Superb iv before this and it had this functionality within the app and on the Infotainment screen. Anyone know how I can find/activate it - seems strange its not available?

New (Used) Fabia Fault Codes

joeninho · 16 hours ago16 hr

Hi guys, Just looking for a few opinions here. Bought my wife a 2012 Mk2 Fabia (1.2 Greenline TDI) a couple of weeks ago from a reputable small garage. MIL appeared after about 8-9 days. Comes on for hours then off again. Rinse and repeat. It is throwing 3 codes: P2016 - Intake Manifold Position Sensor (Circuit low) P2015 - Intake Manifold Position Sensor (Range performance) P0672 - Cylinder 2 Glow Plug Circuit I saw that you can use a bracket to limit the actuator movement on the 2/3 litr
