#1063 of 1064 Re: New Beetle 1.8T P0171 Error [bpeebles] by fphilli1 Nov 03, 2009 (5:31 am)
Replying to: bpeebles (Nov 02, 2009 6:12 pm) Thank you so much for the information. I forgot to tell you I put some fuel injector cleaner in the fuel tank when it was at 1/4 tank and have not added any fuel since then. Would that make any difference? I let the car sit for two days and started it this morning with no issues after I let the blue cooling light go off. I did not wait for the cooling light to go off the other day when I had the limp home mode issue. I know it says to let the engine warm up until the blue coolant light goes off, how important is that???? Thanks again for your help.... Replies to this message: bpeebles (Nov 03, 2009 5:45 pm)

Replying to: fphilli1 (Nov 03, 2009 5:31 am) You said ==> " it says to let the engine warm up until the blue coolant light goes off" VW says to DRIVE GENTLY (accellerate slowly) until the blue coolant light turns off... this is the same as all other vehicles ever made. One should always take it easy on a cold engine. Driving gently is the very quickest way to warm up engine without excessive wear-n-tear. You do understand that the only reason that the NB (New Beetle) has the blue light is because it does not have a formal temparature-guage on the dash to tell you when engine is cold. (VW tried to keep true to the Original Beetle which did not even have antifreeze!!) On the other hand.... letting a cold engine IDLE until it is warmed up is not good for it. An engine takes much longer to warm up when idling. This allows condensation and other nasties to form in the crankcase.
