Hi. I have read the msg on the Bora.  I have a Golf TDI with a limp mode problem. I have changed the mass airflow meter my car does not over boost it has a in-car boost gauge and holds fine it has a new turbo on a year ago.

There is no leaks on the pipes they are on the correct way the only thing on my mates PC it shows the temp reading at 53 deg when in car reads 90 deg and when you rev the car it goes down a little on the pc so i no the temp sensor is faulty is this enough to cause limp home mode?

If you drive the car it boost great at 1500 pulls strong then gets to 2300 and struggles like its getting starved and sometimes I get black smoke out the back and it wont rev or bangs if you hold the car above 2000 rpm in 5 or 6 for a while limp mode happens help please
