Renault Master fault codes

Hi all,

I've had a engine warning light come on and I bought a fault code reader and I've got he following codes. The thing is, I can't find, and neither three mechanics at my local garage can find the EGR valve.

I have the following codes, which I've looked up and linked to.

If anybody could point me in the right direction it would be a great help.

CODE: P0380
Glow plug/heater circuit A

CODE: P0409
DTC - Exhaust gas re circulation sensor A circuit
http://ift.tt/1YruCsy

CODE: P0488
DTC - Exhaust gas re circulation throttle control circuit A Range/Performance
No link

There were six error messages, the following three were the same but had the "pd" symbol which means
"Identifies a pending DTC when veiwingDTC's"

Thanks

Andy
