long term fuel trim lean multi,will it fail MOT?

[gp1]

having trouble with long term fuel trim running lean multi,replaced n75,spark plugs,maf,vaccuum hoses except on from actuator-n75,lambda bank1,coolent temp sensor,forge tip.still not cured if anyone can help?
also wondering with this fault will it fail mot?

fault seems to only comes up on motorway 70mph for abit,boost drops from 0.4bar-0.2bar but boost sometimes drops after hitting 0.5 bar+

Car hasn't been right since i got it,think guy may have adjusted actuator so have tried couple of turns each way + using 12-13 threads.

Please help me get this car running right

Are you anywhere near Exeter? I know a guy who knows everything about the VAG. If he does not know what the problem is i'll eat my spare tyre!

He represented the UK in Spain for some sort of SEAT specialised diagnostic thing. Knows his stuff and he's a REVO dealer! Get your car fixed and tuned at the same time.

Let me know and i'll give you his web address and mobile number.
