I've had my lovely 2005 Allroad Quattro and I am enjoying it greatly, in fact it is probably the best car I've ever owned in nearly 50 years of motoring, and I've had some classics!
Being a perfectionist, when my 2.5 tdi engine hesitated to start on a couple of cold mornings, I decided, after researching the issue, that I will replace the glow plugs. Looking up my car by its reg number the guy at GSF supplied me with a set of 6 NGK plugs at a reasonable £46 and this morning I went out to fit them. That's where the problem began, I can't find them on my engine!
I have the Elsawin workshop manual showing exploded views of the cylinder heads and the glow plugs do not appear on these.
I have spent several hours surfing Google images and Audi forums and so far the detail of how to access the glow plugs of the BAU engine has escaped me.
I can see that there are some connectors, 3 on either side, just above the camshaft covers, each of which vanishes into a hole in the inlet manifold casting. Can someone please tell me that these do NOT feed the glow plugs because if they do it appears that a major operation will be needed to access them ? Please see the attached photos and if you have encountered this problem, or know anyone who has please advise me.
