,

currently having some issues with my w124 400e, the damn battery keeps going flat!?! ive tested for a parasitic battery drain using a mulitimeter and have 1.51 amps with all the fuses and relays from the engine bay compartment fusebox removed??!?, another thing i have noticed is that when i reconnect the battery the fuel pump primes or sometimes stays on but even with the fuel pump relay removed it still draws 1.51 amps?!?, any help or location of any other main fuse/relay locations would be appreciated, thanks
 
I would be looking closely at the starter motor and alternator for a short.

i'll look into the starter motor but ive already checked with the alternator disconnected,
 
also 1 other thing i've noticed is the exhaust temp light occasionally comes on and stays on even with the car off but sometimes the car hasn't even been running,
 
The other areas to to look at would be the ignition switch assembly or the central locking/security/convenience units as these are other systems that will have permanent live feeds due to their function.
