Intermittent P0380 Glow Plug Problem

2 posts in this topic

I had originally posted this in another older thread, but it did not appear on the front page.

 

For this reason I had to start a new thread.

 

 

 

Yesterday, I took my 2005 Cabriolet with 75,000 km on it on the highway for the first time in a long time.

 

After parking the car, when I restarted it, I noticed a check engine light.. A scangauge check revealed P0380 which indicates a glow plug problem. I couldn't clear the code with the scangauge.

 

When I started the car today (no problem starting) , the check engine light came on and the glow plug light stayed on for over a minute, but then the glow plug light went out leaving only the check engine light on.

 

After reading this thread I was convinced that I needed new glow plugs.

 

Later on in the day, I started the car, drove 30 km and when I restarted the car again both the glow plug light and the check engine light were off and everything was behaving normally. 

 

I was hoping that someone who had experienced a P0380 problem could comment on the possible reasons that a code such as this can possibly fix itself.

Is it possible that the car was simply warmer on the later starting, so the glow plugs weren't used and didn't prompt a code?

I've got the P0380 code happening as well, and the car starts fine.  Maybe a bit rough initially, but it smooths out pretty quick.  But in my case, the code seems to be permanent.  Might just be the fact that it's not very warm here; or maybe the glow plugs are in worse condition than yours.
