Help needed please

Has anyone had any starting problems with their A6 after a run when the engine is hot?

I have a 2007 2.0 tdi A6 BRE, she starts first time every time when the engine is cold but i have an intermittent problem sometimes when hot, The starter motor sounds really sluggish like the battery has gone completely flat even though its fully charged, leave it for 60 seconds and she fires up no problem at all.

so far i have replaced the following:

2 x bosch s5 013 830A batterys

2 x bosch starter motors

clutch in to start switch and checked and cleaned both earth to chassis straps.

problem persists and no faults found in vcds

any help would be much appreciated.

Address the oil pump drive or you'll have more than hot starting issues .
