What goes wrong

The AdBlue (DEF) dosing injector on the Kodiaq 2.0 TDI DCHB and DAJA engines fails prematurely, often before 60,000 km. The injector tip crystallises with urea deposits and blocks, causing the SCR system to cease NOx reduction. The vehicle then triggers a mandatory start countdown (vehicle will not restart after a set number of ignitions) unless repaired. The fault was subject to a recall action in Australia and is documented across multiple EU markets. Repair requires injector replacement and SCR system flush.

What you would notice

  • AdBlue system warning light on dashboard
  • Message warning that vehicle will not restart after X ignitions
  • Check engine light with P20EE or P203F SCR catalyst fault codes
  • Poor DEF fluid consumption or no consumption logged

How to check it

Where to look. AdBlue injector mounted in exhaust system downstream of DPF, passenger side underfloor

  1. Scan for AdBlue and SCR-related fault codes.

  2. Check AdBlue fluid level and top-up history.

  3. Ask if any AdBlue warnings have appeared.

  4. Inspect AdBlue tank filler cap area for crystallised residue.

  5. Verify whether the AU recall for AdBlue system has been completed on this vehicle via or dealer records.

Parts involved: Fuel injector.

What it costs to put right

$1,200 to $2,800 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

  • “Has this vehicle received the AdBlue system recall action?”
  • “Has an AdBlue or SCR warning light appeared?”
  • “Has the AdBlue injector or pump been replaced?”

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.

How much does it cost to fix on a Skoda Kodiaq?

$1,200 to $2,800 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Skoda Kodiaq years are affected?

Our research records this fault on the 2016 onward Skoda Kodiaq. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.

How do I check for it before I buy?

Scan for AdBlue and SCR-related fault codes. Check AdBlue fluid level and top-up history. Ask if any AdBlue warnings have appeared. Inspect AdBlue tank filler cap area for crystallised residue. Verify whether the AU recall for AdBlue system has been completed on this vehicle via or dealer records.
