hi. my 2003 110 tdi is being annoying again. it was overboosting when i got it so i cleaned the turbo out with innotec and it was fine after and the linkage was free etc then it got a bit lumpy so i had the n75 boost control valve replaced and it was smooth again, now yesterday it went into limpmode going up a hill so i thought its just because i have not given it some go in a while... given it some thrashing for a couple of days and the linkage is all free but it seems to go into limpmode when i floor it for the first time after its been started, hot or cold it does it but once its done it that once it doesnt do it again?? any ideas what it could be? time to clean the intercooler out?? its done 167000 miles
