I am confident we can resolve your problem together. Pleaseunderstand that I don't know your skill level. In most cases when you have a problemwith the way the vehicle performs, specialized tooling is required to acquire computerdata/information or engine testing results. We didn’t build these complicated vehicles; wejust diagnose and fix them. Also understand that I can't see, smell, hear, or touch thevehicle either, so it may take a few replies to get to satisfactory results. Note there may be an issue where the complexity of the issue will require a Premium Service. This service will be an addition to the normal question cost. Usually it does not come down to this but keep in mind!! I am also going to direct you with the fastest, easiest and most common things to check first. Please bepatient and permit me to do what I do best.I also try to give all of the information you may need, expecting a “positive rating” inreturn. I will also continue assisting you after you have rated me, if necessary. If thereis any reason I cannot get a positive rating, please let me know why “in advance”, so Ican go another direction for you. I am sorry you’re having this problem; I’ll help youthrough it.Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail.
i do need some more info please.
do not do that!!!! p0380? got to have the codes!!! what is the resistance of each glow plug?
because with a bypass you can go into a limp mode (reduced power). so your real issue is the starting rough in the morning. first thing is the injection pump timing needs to be checked and a VAG COM scan tool is needed because it is read by the scanner and adjusted if needed by the injection pump. hence the codes may give other faults .
snap on scanner is good if euro is loaded and used . global obd may not get manufacturer specific codes
due to site regulations that is not possible . the only way is to authorize the premium service offer!! Site rules!!
not too common . i have seen glow plugs get high resistance from time to time. i do believe you have a different issue with startup!!
no disrespect either but without the codes and a scan tool how can i help out in my end . help me to help you!!
