Any of you guys no much about the vw scirocco's, i have got 1.4tsi had it a week and my engine light has come on and it does not go over 3k revs. I have put it on a diagnostic and it is showing MAGNETIC CLUTCH FOR SUPERCHARGER SHORT TO GND. what does this mean ....

 

Problem is that the coolant pump on the twincharger is combined with this magnetic clutch twopulleys sticked together.
Happens to a lot of tsi's is that the clutch goes bad. When it goes bad the pulley for the supercharger is not locked and the supercharger does not work when needed thus making the car rev very slowly till 3500rpm (limp mode) after this the car is turbocharged but the air flows through the not working charger blades thus slowing the air intake in to the turbo making the car less powerful up to the end.
Hope this helps its from my brother who works for vw, he said that they had problems with the turbos is it under warranty?

 

No im assuming its not as its a 2009, so what needs soing exactly now ?

 

Short to gnd is electrical related. Checked the connector at the blower first.

GND normally stands for an Earth ir Earthing point.

Maybe a bad earth no??

 

Short to GND is a generic term used in VAG diagnostic's. It can mean short to gnd or no gnd (earth) at all.
