A3 TDI problems getting worse. Help please?
Hi all, we have a 2004 A3 2.0 tdi, done 115k now. For a long time it has struggled to start when warm and the whole car judders at temperature when stationary. We had he car looked at and said they couldn't find anything wrong (no fault codes or unusual readings). So we have left it and now two years on we have the fan coming on constantly (I know I need a new fan for this just haven't found one yet and don't want to pay out for audi prices!) but also we keep having the coil light on the dash continuously flashing while driving along with reduced power. Now last name night the light stopped but when we set off in the car there was no power when pulling off and it would bog down when changing gear until it seemed to get warm and it stopped and drove fine.
Has anyone got any suggestions on what it could be? I am going to get it scanned for faults and checked over ought id ask here incase anyone could tell me what to do/check.
As you can imagine it's dangerous loosing lower while changing gear like the idiot last night following too closely behind me nearly found out!
Any help much appreciated!
