A6 2.0tdi Ultra (Glow Plug Replacement)

[DavidMitham1992]

Hi all,
I recently got an engine management light in my dash. Turns out it's glow plug fault on Cylinder 1. I've got the glow plug from Audi and now going to replace it.

Audi A6 2.0 TDI (190ps) ultra

- Has anyone ever done this before?
- Any considerations to take?
- What is the torque value when tightening new glow plug?

Thanks
David

Hi David, I have not changed glow plugs on this engine yet but it looks as though its a fairly straight forward proposition from the access point of view from experience I would personally change all four as rest assured the other three failing will be close behind.

please observe the following, the engine has to be warm not red hot, use a quality deep socket preferably wall drive, use a suitable extension for the socket and a longish breaker bar to turn the socket, use gentle force to move the plug if it won't give use plus gas or similar and leave to soak, try again when it gives if it is stiff when coming out apply more release agent and gently tighten again, undo as far as possible and if the plug still binds repeat the previous operation until it turns freely, on reassembly smear a film of Aluminium anti seize paste on the thread of the new plug.

The torque value is on the internet but as a rule of thumb it is normally between 10-12nm, whatever you do don't go berserk when undoing as if you snap it off they are hell and a rather expensive extraction kit.
