2016 Peugeot208 Diesel ECU high oil pressure fault

I am selling my 2016 Peugeot 208. I bought it 3 months ago. I invested quite some money to get it ready for the NCT. Unfortunately, two weeks after passing the NCT it broke down. The ECU shows a high oil pressure fault. The error could either derive from a faulty ECU or the oil pump. Because we don't know for sure if it is only the ECU or also a mechanical issue with the oil pump and I do not have the resources to put more money into the car after all the previous investments, I'm looking to sell it to an interested mechanic. It was very nice to drive before it wouldn't start. If you can fix it cheaply, you can definitely get some profit out of it. Recent Work & Condition: Peugeot 208 Year: 2016 Diesel Mileage: 120 k km Timing Belt has already been changed before I bought it Good condition inside and out NCT: Passed in May 2026, valid until May 2027 Tax: paid until April 2027 Tyres: 4 brand-new tyres. Brakes: Brand-new brake pads. Sensors: New front-left ABS sensor. Oil: Fresh oil and new oil filter. Logistics: Must be collected / towed away from garage in Carrigaline, Cork. Considering all the work that has been done so far, I would like around 2800 € for the car. I am open to reasonable offers. DoneDeal message preferred due to work hours.
