Third EGT sensor range fault.
P2036 — also written P2O36, P 2036, 2036 — is the OBD-II code for egt sensor circuit range/performance (bank 1, sensor 3). Same code, same fix: this page covers every spelling of it.
This code means the third temperature sensor in your exhaust—usually the one right after the DPF—is talking nonsense to the ECU. It’s a classic headache on Euro 5 and 6 diesel VAG and Vauxhall engines.
P2036 is a emissions fault code, typically costing £90–£400 to put right in a UK garage.
What P2036 actually feels like to drive
- Engine Management Light (EML) staring you in the face.
- Car goes into 'Limp Home Mode'—feels like you're towing a caravan.
- DPF regeneration won't start, leading to a 'Soot Accumulation' warning.
- Fuel economy drops through the floor as the ECU plays it safe.
- Stop/Start system stops working (standard safety lockout).
What causes P2036?
- Aged sensor
- Wiring routing damaged by heat

The P2036 misdiagnosis that wastes money
I’ve lost count of how many times I’ve seen folks chuck a brand-new DPF at a car for this code because their generic scanner said 'Emissions Performance'. It’s a total waste of a grand. They assume the DPF is blocked because the car’s in limp mode, but the actual culprit is usually just this £90 sensor reading 'frozen' or 'implausible'. I’ve also seen people swap Sensor 1 (pre-turbo) by mistake—always check the live data to see which one isn't dancing before you get the spanners out.
What a UK garage should charge for P2036
A mobile diagnostic will cost you £50-£80 just to read the code. For the fix, a genuine Bosch or Denso sensor usually runs between £90 and £140 from a factor like Euro Car Parts. Labour is the wild card; if it comes out easy, it's a 30-minute job (£50). If it's seized and needs the oxy-acetylene torch and a thread tap, you're looking at 2 hours (£150+). At a main dealer, don't expect much change from £450 once they've added their 'standard diagnostic fee'.
P2036 repair cost in the UK
Most P2036 repairs land between £90–£400 including parts and labour. The spread is wide because the cheap fix (a sensor, a hose, a leak) and the expensive fix (a major component) throw the same code — which is why a proper diagnosis before parts are bought saves the most money.
Bob's tip on P2036
If you’re taking this to a garage, ask them to 'graph the EGT sensors' on their diagnostic tool. If Sensor 3 is sitting at a steady 100°C or a maxed-out 900°C while the others are moving, you've found your ghost. A big tip for the DIY crowd: don't bother trying to save the old sensor. They weld themselves in with heat. Get a proper 17mm flared EGT nut socket and some 'plus-gas'—and be prepared to use a blowtorch to get the boss red-hot, or you'll strip the threads right out of the exhaust pipe.
