My vw 2000 1.8t passat has trouble idling. Anyone?

When my vw passat 2000 1.8t 20v straight 4 comes to a stop, the revs go crazy and the lights flash like a nightclub. my car revs go up and down more often when my lights are on. the revs stil fluxuate when headlights arent on but not as bad. initially i thought it may b the alternator but what should i do.

It "might" be your throttle position sensor, look for some electronic's going into your or near your throttle body and clean them with disc brake cleaner, something that won't leave a film on it.
This was the problem with my chevy, I know it not the same car but it's worth a try, cheaper that replacing it.

My vw passat (an automatic) stalls when I have to come to a stop a lights, or even sometimes when I have to slow right down to an 'almost' stop - any ideas what the problem might be ????


Probably the IAC which control the idle but usually you will see some erratic idling as well. Pretty sure something to do with the control of idle and fuel. Maybe you need to clean throttle body and raise idle some might help. Have IAC checked.

1998 VW Passat it seems the idle is to low how do


Idle is automatically set&monitored with a timing sensor on the camshaft, i found my engine(1.8 20v turbo) would idle low then go high and almost stall sometimes and all i did was remove the fat black pipe on the throttle and clean inside the throat with a cotton rag dabbed in wd40.Hold the throttle open manually and clean on and around the throttle plate as the oil burnt&recycled creates a hard carbon that stops the throttle working correctly.When did you last change the sparkplugs, air filter, oil and oil filter and remove damp from the spark plug area using wd40 on surfaces applied with a cotton rag.These contribute all to your problem.As you dont state milage etc it could be a worn engine or slipped cambelt(1-2 teeth can make a slight diffirence).

Just bought vw beetle 54 plate 1.8 20v turbo. between 1000 & 2000 rpm any gear except 1st gear hesitates quite bad then clears once rev's pick up. any temperature. Above 2000 rpm no problem but also...


it could be the maf sensor,the coolant temp sensor or the throttle body.you will need to have a suitable diagnostic machine connected to read what trouble codes are in the ecu.

replace your fuel filter first. If that does not do it, then try an air-flow meter. (if the check engine light is on it may be an airflow meter.
