Need a new inlet manifold apparently... options?

Hi all,
As the title suggests, apparently my temp sensor in the inlet manifold has gone. I'm getting a hard fault code. Local VAG dealer has quoted £760 for replacement, which is insane... I can't believe the inlet manifolds aren't serviceable.

What are my options?! 2.0 TFSI, 2005 A4 B7 sline.

Many thanks in advance!!
 
What's you engine code?
It's the BGB, which I understand is the 200HP version. Yeah, I was thinking a second hand unit would be my best bet, but obviously you run the risk of buying a lemon. Also, what sort of gasket set would I need to do the job?

As an aside, what are the differences between the 200 and 220HP versions of the engine? Just a different mapping, or are there physical differences? I'm looking to remap the car in the near future once it's running sweetly, so if I could put on a later model inlet manifold that offers more power, etc. now would be the time.

ooh, also - is there a guide to doing the swap out there?

Many thanks in advance.
 
Mostly mapping is the difference,different compression ratio on the 220 BUL codes,harder camshaft so less fuel pump lobe problems.Plenty of guides to help out there.No power difference between manifolds.Just make sure its a a4 manifold not a transverse type.
 
Sorry if I am misunderstanding something but why can't you change the temp sensor? Why do you need a manifold?
This was my first thought, but apparently, it's all a single unit that can't be changed.
Also, the faults that I personally read from a non-VAG reader said an error with an inlet manifold position sensor. The VAG mechanics said it was a temperature sensor.

Seems utterly insane that a temp sensor & position sensor can't be unscrewed and a replacement put in, but this is how I understand VAG engines are.... You basically replace a third of the engine if there is any small fault with any single component.
 
Well, this is what I got from my mate's reader. I took it to the audi dealer, and the guy behind the desk mentioned temperature sensor, but I'm not so convinced. Obv the position sensor needs looking at, so if they can be swapped, then that would be a good start. If it's not too much money or effort, I'll swap the temp sensor while I'm at it, too.

I also have the part number for the appropriate inlet manifold, though unfortunately, not with me right now.

Thanks in advance.

Isn't that a swirl flap problem? I could be wrong but that's what it looks like it to me.
I honestly don't know! I'm more used to working on two-strokes and rover V8's! :) How can I tell?

Symptoms are an unstable idle, and misfires at lower RPMs.

Hopefully someone here who's more expert than me at reading VCDS codes will come along and tell you.
 
Ok, I'm not 100% but I think what you've got here is a worn linkage on the inlet manifold swirl flap. It's more common on 3.0TDi engines. but can happen to 4-cylinder engines too.

A repair kit like this one followed by a VCDS fault re-set might be enough. The one in the link is for a V6, but it might also fit yours, or if not there should be an equivalent. Ring your local dealer or TPS if not sure.

Thanks! £17 is better that £780, so worth a shot. Can't I inspect the inlet manifold to see if the link is worn now? Would it be broken, or stiff or soemthing?
