TDI 110 boosting issues

[roscotdi]

hey all a have a ibiza tdi 110 02 plate having trouble with boost keep hearing my 109 relay clicking and also replaced it but still does it had it on vag com and my maf was sitting above a 1000 on the actual dont really know wat that means if someone can help the car has gradually lost performance a can hardly reach 80 on the motorway cant overtake sometimes get boost sometimes dont and when a do get it its sometimes a little bit or its like a get overboost checked all my vac hoses and cant find any splits and none on boost hoses a feel like banging my head of a wall lol

Can you get vag com to log the boost and post the results?

Certainly sounds like a strange one though, the fact your new relay 109 is clicking is worrying, that is the main power relay....

When you say about the maf actual sitting above 1000, was this all the time? can you post the log?

Thread moved to TDI section for better exposure.

Not sure about the relay though, i seem to recall mine doing a little clicking down there when cold but it was several years ago now so my memory might be failing me sorry...
