LCR Wouldn't Start - Vag-Com showing 2 codes

[Chet T16]

17069 - ECM Power Relay Control Circuit (J271): Open Circuit
P0685 - 35-10 - - - Intermittent
17925 - Power Supply Relay for ECU (J271 or J363): Electrical Malfunction
P1517 - 35-10 - - - Intermittent

Can anyine throw some light on what/where the J271 relay is or if these codes point to something else?

The car has failed to start twice in the last 3 weeks, it just turns over for a bit then will fire up and run rough with the EPC light on. Turn it off and start it again and it'll be fine

Any help appreciated!

Sorry to bump an old thread, but can anyone answer this please?

Luckily i had an email subscription to this thread! I figured out the problem

The relay is under the bonnet in a little box of its own. I pulled the relay out and noticed one of the spade connectors in the relay connector was sitting a bit low. Sure enough it was unclipped so when the relay was pushed it the spade connector was pushed out the bottom which gave the intermittent connection. I clicked the wiring back into place and i haven't had a problem since

Ok, it's a bit late now but I'll try tomorrow night.

Thanks for the reply .
