Question, 99 Jetta TDI, understanding glow plug sequence? This car is running well and you can delete EGR code as cleaned the coke out of it and
replace 1 vac line all is good. It has been a little grouchy in the morning around 32F, or 0C. Monitoring this on a DSO and VAG, I note 4 plugs come on for only 6 seconds grid Q6, to the cyclinders, then turns off. Once you crank and start Q6 ( the 4 cylinders) comes on and stays pulling 32 amps and dropping over time once started. I notice glow plug only comes on for 6 seconds, (DSO) then turns off. Can't view this on Vag as it takes more than 6 seconds to obtain address once key is on. I am used to Cummins, and International which will come on and stay on for around 10/20 seconds before commanding ready to start. 6 seconds seems short to me. I notice if I cycle the key now knowing it is only on for 6 seconds, I do this 3 times and it barks much easier. The car always starts I just feel the crank time is long, but maybe normal.
The 2nd question is?, this is a standard transmission and there are 3 glow plugs in the goose neck making a total of 7. There is no power amps or voltage on the 3 in the neck but they are actually run in 2 stages, depending I guess? These are ran from J360, J359 relays. My question is ??????????? My bently states these 2 relays are in the motor compartment and there are 2 relays a 53 and a 100 labels and I don't know if these are the 2 in question as there is no numbering around them on the relay frame. I can back probe T80/34 and T80/17 which excites these relays but maybe VAG or or VW does not target this system unless it is colder than what I am at. This would tell me if the relays are actually being commanded or not.
What is the strategy here? as would think the ECM would turn on one or both of these relays to heat up the water in the jacket. These are not I'm told used on the automatic trans as it creates enough load to warm, don't know. I see no codes illuding to them not funtioning, and have not tried to disconnect and create a code to see what happens, might go there.
Happy New Year to all
