Guest markae53 Posted May 20, 2005 Report Posted May 20, 2005 have got 1.9tdi 98 model. since august 04 have been losing oomph @3000rpm/70mph. feels like someone is standing on the brake. after it happens all the turbo boost disappears (althgough the turbo whine is stlll heard). if you turn off the ignition everything seems to reset until you hit 3000rpm again. have taken it to 2 garages neither have been able to solve the problem. have had boost pressure valve changed and vacuum pipes. have been told that the problem could be sorted by changing out the mass airflow meter (no problems found on diagnostics) anyone got any ideas Quote
Masked Marauder Posted May 21, 2005 Report Posted May 21, 2005 Yep, always go for the MAF first, classic symptoms, do a search and you will find a host of information. Quote
Guest markae53 Posted May 21, 2005 Report Posted May 21, 2005 many thanks - looks like sunday morning will be maf cleaning day! will let you know if it is succesful. if completely dud - where is best place to get a replacement? Quote
Guest pnwheels Posted May 22, 2005 Report Posted May 22, 2005 If its not the MAF, then almost certainly its the turbo wastegate sticking, (is yours the 90hp model- AHU code?) Various posts on here describe testing and cleaning the wastegate. Quote
Guest markae53 Posted May 22, 2005 Report Posted May 22, 2005 Thanks to all for replying - have cleaned maf, initial reaction seems to be that it has been a success. will have to wait foe a long run with a hot engine to be completely certain. am going to send a few forthright letters to the garages i used! Many thanks again - will return here first if there are any more problems P.S. i think mine is a 90bhp Quote
