2006 vw jetta 208k miles outside air temp 43f tried to start the glow plug lite blinking, would not even try to start no other warning lites on, ckd brake lites ok, no previous problems even with colder weather.
Will it show a code with out the eng. running,I have an obd unit.
Just key 'ON' is all you should need to do before scanning.
As above, issue will have nothing to do with the glow plugs... flashing light just means the ECU has detected a "FIX ME NOW" issue. Brake circuit problem, injection pump problem, accelerator pedal, potentially glow plug relay itself... there's 20+ possibilities unfortunately.
You'll need to track down a VW-specific code reader... the code will be there, just not accessible with a generic OBD2 scanner.
Yep - you're not going to do much better than VCDS. If you're going to own a 10+yr. old car for any significant length of time, this will pay for itself in year one, almost for sure.Most other manufacturers propriety scan tools run several thousand dollars often with a monthly subscription on top of the purchase price that will be 2 hundred or more per month. Ross-tech vcds is very reasonable.
You said the glow plugs are all ohm'ing withing 0.1 of each other? and they are all about 0.9?As expected the glow plug harness fell apart,. and the glow plugs are the original, so I will change both, is there a vw code reader I can buy for a reasonable amount.
Please clarify "would not even try to start"2006 vw jetta 208k miles outside air temp 43f tried to start the glow plug lite blinking, would not even try to start no other warning lites on, ckd brake lites ok, no previous problems even with colder weather.
Engine turned over normally, tail lites are working normally, heard fuel pump work,Please clarify "would not even try to start"
Did the starter work and the engine crank over?
Do you hear the fuel pump in the tank running for a few seconds?
Scanning for codes to diagnose it should be cheaper then throwing guessing at it parts.
As mentioned above, did you check if both brake lights are working?
I had that cause the GP light to blink.
VCDS Lite is free to use but has a few functions not enabled.is there a vw code reader I can buy for a reasonable amount.
Any shop to diagnose and fix this will have at the very least a VCDS (or equal) device. Though not necessary for fuel delivery, you need to find out what's up with the blinking.I have the car in a shop now and have been told the tank lift pump pressure is low 5 psi, what I have read is that a pressure of 5 to 7 psi is normal, the car will run using an alternative fuel supply for a short period of time until the fuel runs out, this shop has been very good but vw tdi may be too much for them all I can think of now is the dealer maybe somebody can give me a better idea.
