Hoping anyone can spread some light on this one for me my car starts fine anytime it's cool it's an Audi a3 tdi 1.9 but when it's warm it seems to struggle I recently changed the dual mass flywheel clutch and beating but this fault was there before this has anyone got any ideas?also I have noticed my speedo and rev counter seem to fluctuate when I let off accelerate only by the smallest of margins is this me being over cautious or is this another problem hope you can help thanks!!!
