2.0 TDI 140- injector question

[ManOpener]

A colleague has an '08 B7 A4 2.0 TDI (140) which is exhibiting some stuttering on part throttle/moderate load. Doesn't seem there at high load.
Local garage has diagnosed it as being an issue with #2 injector. Quote for replacement I can't remember, but seemed very high.
Any idea on what the cost for an injector replacement should be?

They are known to be expensive parts and hard to change due to the need to have a very clean environment.

Doesn't surprise me that the quote has come out high. Have you found the price now?

Funny that, i had the same problem on my '55 plate T5 transporter. After a trip to my indy for a scout on Vagcom i got number 1 injector faulty.

Luckily for me he said its more than likely its the injector wiring loom which is located inside the head.
£55 and an hour of my time i had the part replaced and the van working again.
To top it all my 2.0 TDi 115 mk4 golf developed the exact same fault 1 week later. Back on Vagcom and guess what number 1 injector was faulty.

This time though he said it is actually probably the injector. I took a chance and purchased the wiring loom and spent another 1.5 hrs stripping the rocker cover off and replacing it.

Problem solved
Take a look on some forums and see how common it is

He can't remember the quote off by heart (will get back to me tomorrow), but the engine is a BRE code one- so PD140.
Think it was something like £380 inc VAT for parts and several hours labour for a total bill of £650.

Bit of a bump here. He's had the injector changed, issue is still present. I've suggested he takes it to an actual specialist but aside from the wiring loom v(which I don't know whether was changed) any other ideas what could be causing it?
