Mercedes-Benz E-Class Manual 186PS

May swap Mercedes E-Class 1.8 Kompressor, 6-Speed manual. Starts runs and stops. Down on power and will only reach motorway speed with the MAF disconnected, symptoms point to either blocked cat/secondary AIR system malfunction (throwing P0410 code). AIR system blows off the vacuum lines connected to it. O2 sensor thinks the car is running rich when it isn't and pulls fuel above 2000RPM. Car can be sold with a laptop loaded with MB-STAR/DAS and OpenPort multiplexer for diag/mapping. NCT 01/27, Tax 07/26 New parts include: Camshaft adjuster solenoids (2025) Exhaust manifold (2026) New Battery (2025) 4 New Tyres (2025) 4 Spark Plugs, oil, filters (2025) 2 Coils (2025) Back rigid brake lines for NCT (2025) Crank position sensor (2025) Thermostat, new coolant, refreshed power steering fluid, oil, filters(2026) Drive belt and tensioning + idler pulley Alternator Timing chain sounds like it has life in it, no bad rattle off it. Would be a fine car if properly fixed. Bodywork is clean for the age, underneath is spotless (including the sills under the covers). Selling as I don't have the motivation to fix it. Features: 2 Zone A/C (that works), CD changer, cruise control, full cream leather (drivers seat is torn). Will be sold with a replacement upstream O2 sensor and a replacement secondary air valve along with some other spares. Please message before calling. I'm happy to answer any questions by message also.
