Audi a4 b7 3.0tdi glowplug issue


Registered User
Hi guys,

New here

I have a issue with my b7. Starts fine and drives fine. As soon as you need more power, the glow plug light starts flashing and I have a loss of power. Switch off and on, it's gone.

I did a vcds scan, and it gave a glow plug fault on cylinder 2.

I replaced the glow plug, and still giving the same issue.

Any help or ideas?

Glow plug light flashing usually indicates another fault, i.e. nothing to do with Glow plugs. You must have had a Glow plug down anyway, so that out of the way you now need to find out what is causing the light to flash. Not something I have had before but I am sure there will be posts on here if you do a search or someone else who has had it may come on and give you an idea. I am thinking running issues, Turbo boost, maybe EGR/inlet manifold problems?
Hope you have success getting it fixed.
