Question about 2000 Volkswagen Passat 4Motion
Hi if your car starts fine when cold but then runs rough when warm then wont start this points towards the oxygen sensor ( or lamda sensor for its proper name) being at fault, if your sensor in the exhaust comes before the catalytic converter then i would say its the sensor at fault how ever if the cat comes first then it could be that that is at fault.
your best option would be to have a diagnostic check done so your not wasting monery buying parts you might not need.
let me know how you get on or if you need further assistance ok
