GOOD MORNING EVERYONE THIS TIME NO DIAGNOSIS BUT MECHANICAL PROBLEM :

AUDI A3 YEAR 2004 ENGINE 2000 TDI 103 KW BKD WORKSHOP REPLACES CLUTCH KIT AND BIMASS FLYWHEEL BECAUSE CUSTOMER COMPLAINED OF NOISE WHEN SWITCHING OFF.

I DELIVER THE MATERIAL BUT THE NEXT DAY THE MECHANIC CALLS ME AND TELLS ME THAT THE FLYWHEEL IS DEFECTIVE BECAUSE IT HAS THE SAME PROBLEM AS BEFORE AND HIS FELLOW MECHANICS SAY THE SAME THING.

I TELL HIM TO WAIT TO DISASSEMBLE EVERYTHING AND GO TO THE WORKSHOP TO SEE, IN FACT RAISING THE CAR ON THE BRIDGE AND LISTENING FROM UNDERNEATH YOU CAN HEAR THIS NOISE BUT ONLY WHEN SWITCHING OFF.

I HAVE NOTICED THAT WHEN THE ENGINE SHUTS DOWN IT WOBBLES, WHICH IS ABNORMAL.

I OPEN THE BONNET AND FIND THE CONNECTOR GOING TO THE AIR SUPPLY REGULATING FLAP DISCONNECTED, THIS PART NOT ONLY REGULATES THE AIR FLOW BUT ALSO SERVES TO REGULATE THE ENGINE SHUTDOWN!

I ASK WHY THE PLUG WAS UNPLUGGED AND THEY TELL ME BECAUSE THE COMPONENT IS DEFECTIVE IT BLOWS THE FUSE AND THE CUSTOMER DOESN'T WANT TO SPEND, AND THAT ACCORDING TO THEM IT'S NOT NEEDED AND THE DEFECT IS IN THE FLYWHEEL.

I GO BACK TO THE SHOP AND GET THIS COMPONENT AND TEST FIT THIS NEW ONE.

WE TEST THE CAR AND EVERYTHING WORKS FINE TO THE AMAZEMENT OF THE MECHANIC!!!!!!!

THIS ALSO WENT WELL.

GOOD WORK TO ALL .
