Have Transmission Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
You wrote manual shift, does that mean it has an automatic or manual transaxle?
Do you have the ability or tools to see which codes are stored?
When you say it would not engage does that mean it was stuck in neutral, you could not get it into any gear with the clutch pressed?
So while in gear, engine running, the clutch pedal not applied. It acted as if it was in neutral?
That is one odd clutch system failure, to the point of almost never occurring. For this to occur the pressure plate would have to be applied so there was no pressure on the clutch disc just like as if you were pressing the clutch pedal in. Possible causes are the pressure plate sticking, the release bearing binding on the input shaft, or the slave cylinder sticking.
For the flashing glow plug light that just means there are codes stored. One or more of hundreds of possible codes. A tech could not even come close to guessing and being accurate. A scan tool is a must to see which codes are stored.
These 2 issues are not related, just a coincidence they occurred at the same time. Something electrically related has caused the flashing light and the clutch concern has nothing to do with electronics.
This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.
Hello again Chris here,
Are you asking for the diag steps for code 1639?
1639 means there is a concern with the TP sensor, this can cause the glow plug light to flash. If needed the diag steps are below for this code.
