Biddulph Posted August 17, 2009 Report Share Posted August 17, 2009 I have a VW Polo 1.2 05 Reg which intermittently shows a ESF light. It occurs in the nature of things when starting the engine but remains on. A top up of fuel appears to trigger it and strange as it may seem - stopping the engine and removing and replacing the dipstick takes the light away. I stumbled on this after thinking that the problem was linked to the oil level having recently changed the oil. It has been suggested that closing the bonnet could influence things - but this has been tried without effect! For most of the time all is well - there are no signs of anything being wrong with the engine - It's a niggle which could be more than a niggle when MOT time comes round! Any help would be gratefully appreciated. Biddulph Link to comment Share on other sites More sharing options...
Biddulph Posted August 25, 2009 Author Report Share Posted August 25, 2009 I've made some progress - a code reader has come up with 16726 - but this doesn't feature in the instruction manual code list - Help! Biddulph Link to comment Share on other sites More sharing options...
burble Posted August 25, 2009 Report Share Posted August 25, 2009 From memory 16726 relates to the camshaft position sensor. Link to comment Share on other sites More sharing options...

Biddulph Posted September 30, 2009 Author Report Share Posted September 30, 2009 Fault 16726 camshaft position sensor continues to present itself! This intermittent manifestation has only occured since a recent oil change. In the process of the oil change I allowed the oil level to flood the camshaft housing as I was re-filling the sump. I am wondering now whether the access oil has 'fouled' the sensor causing it to emit a low signal from time to time. Today I removed the sensor and cleaned it and for the present all is well! It would be reassuring if someone was able to confirm my suspicion! Thanks, Biddulph Link to comment Share on other sites More sharing options...
