Another relay 109 question
Howzit guys
As you probably seen my 1.4 tdi is not starting at the moment, no idea why.
Also cant scan at the moment, cheap scanner says P0726, other scanners dont work, i need a proper vcds.
When i pull the relay out the CEL goes off, and the glow plug light no longer flashes.
can i assume the relay is linked to all the sensors causing the CEL? obviously it doesnt start without the relay coz the pump doesnt activate without it.
I just basically want to confirm that the relay is linked to the sensors, or whatever is causing the CEL light. do you think i should buy a new relay and see then?

Re: Another relay 109 question
P0726 is generally the code for an engine speed sensor. it sometimes can be a nuisance code as it will record it during extended cranking or it might be the one stopping you ie. the engine speed sensor is actually dead. You need to go to measuring blocks and see if there is RPM showing on the management. You really can't do this or diagnose that car without vcds. Without it you are shooting in the dark blindly.

Re: Another relay 109 question
Howzit Panic, yes sir, ive been cranking for long periods at a time, so it would make sense, even though the speed sensor was replaced, it still makes no difference, im gonna have to make a plan for vcds one time and get it done. ill speak to the minister of finance (wife) and see what we can chop next month. right now im just trying random stuff.panic-mechanic wrote: ↑Mon Apr 30, 2018 11:22 am P0726 is generally the code for an engine speed sensor. it sometimes can be a nuisance code as it will record it during extended cranking or it might be the one stopping you ie. the engine speed sensor is actually dead.

tell me the brake switch will have no impact on that error or CEL in anyway? coz i just noticed there is no switch its completely gone, just wondering probably has nothing to do with it not starting.

Re: Another relay 109 question
canned over the weekend, VCDS says P0321, but the crank sensor is new, im thinking i must try the TPI 2007067, but i see it only works on new software my car still has the original as far as I know, is there anyway to check what my current version is with VCDS?

again - says you have a faulty rpm sensor. did you go to measuring blocks and see if it shows you rpm when you crank. If management no see rpm there will be no starting.

Re: Another relay 109 question
I decided to strip it turn out the reductor wheel tone wheel or speed wheel whatever you want to call it is damaged. It bent badly why becuase the shims were not installed when the crank was replaced so the crank has loads of play causing the wheel to scrape against the inner block so i it bent out of shape making it impossible for the sensor to pick up a reading if i knew how to upload pica i wouldve done so
