Basically this means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1

A code P0172 may mean that one or more of the following has happened:

  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehiclesError p0172 on a gti golf 2001. How do I solve it - icon1.png where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak.
  • There could be a fuelicon1.png pressure or delivery problem
Possible Solutions
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Cleanthe MAF sensor. Consult your serviceicon1.png manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect fuel lines for cracks, leaks, or pinches
  • Check the fuel pressure at the fuel rail
  • Check the fuel injectorsicon1.png, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
  • Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)

it is probably your door lock has gone into safe mode.you need a new door lock.try using the lock/unlock button on your remote or on the drivers door button and gently tap the door handle with your hand while pressing the lock/unlock button,carefull not to dent your car.if that does not work,try disconnecting the cars battery for a few minutes,but note the vehicle might pick up fault codes which need a diagnostic machine to clear...good luck

SOURCE: electric windows not working, how do i fix this golf gti 115 mark

To isolate your problem a few questions needed.

  • Do you hear any noise when you hit the switch
  • Does it move a bit
  • Can you operate it from the outside locking mechanism
If you can hear the motor (regulator) but window does not operate, then we established that power is being supplied and fuse/relay are ok. Your problem is a bad window regulator or a guide cable is fraying and caused it to knot up on the guides.

If you hear nothing at all then you first need to figure whether it's a fuse, a relay or the wiring is bad.

2001 VW Golf 2.0 throwing error codes P0103 & P0172


Vacuum leak somewhere.
Possibly could be the O2 sensor (the one before the cat up front).
I'd search for a vacuum leak since you may have rattled something loose.

it might be the e break sensor . ive heard of them causing shut downs . also check all fluid levels if your coolant is too low the sensor will shut it down lol. and i think theres a break light recall that might have something to do with it . take it in to vw if you have the means for a scan . of find someone in your area with a vag com . it can read the error codes from the computer . good luck
