My first post on here so be gentle. I’ve recently bought a Lupo 1.4 16v, with a whole list of problems but it was too cheap not to buy. The engine runs but the epc and engine check lights are both on. Had a scanner on and one fault listed was open circuit heater on the pre cat lambda sensor. The guy we bought the car off told us he had fitted a new one, and it definitely is new. I’ve tested it with a multimeter and between pins 1 and 2 are open circuit, I wonder tho if the part is faulty or the wrong one for the car. On checking the resistances on other pins I’ve found a pair that read 4-5 ohms (most likely the heater connections), which leads me to think the plug on the new lambda sensor is wired up wrong. Trouble is I’ve not got an old one to check it against. Woundered if anyone on here had one they could meter out or a new one with the same colour coded wires as mine. Or any other ideas gratefully received. Will try and attach a pic. The part number is OS092 RTG Automotive

Alright folks. I'm new to the forum and have just bought a 03 reg lupo s 1.4 16v. It runs and drives fine and I know the guy I bought it off who has done a full service on it recently. When the car starts the dash is clear but on pulling away the oil light comes and and beeps. I have read it may be the fuel pressure swith or a blocked strainer in the sump. Is the strainer just a mesh in the sump which I will see if I take it off? Also I think its the eml on too, when on the code reader it says o2 sensor, cant remember the exact thing its showing. Is there a way to tell if its a dodgy pre or post cat sensor? As I'm new to vw I'm not sure... If I go down to the scrappies can I take a lambda of any petrol vw? Or does it have to be the same lupo? Same with the oil pressure switch?(although they're cheap enough anyway) Thanks in advance
