P2015 Engine Code

[alc]

Hi there, 

My 2010 TT 2.0 TDI went in to Audi for the recent emissions update. It had previously been running like a complete dream for 2 years prior without ANY issues. On collecting my car Audi said that i had an EML on and that i'd need a new intake manifold (£800!!) Now this was over a year ago and the car hasn't had any problems but the EML is still on. I'm now looking to sell the car and just wondered whether there was anyone out there that could advise me on a cheaper fix...and yes, tried the brackets but there currently isn't one that fits my manifold. 

Thanks in advance,

Alice
