Old or modified VSA?

[ROAD DETECTIVE]

Hi all
I wonder if anyone here knows the answer. I have an 04 CTDI, bought the beginning of last year. My question is this, has my VSA been replaced with a modified one? The numbers on the part are
57710-SEF-E551-M1.
DE (TYPE:EFVVV)
Ate 06.2102-0117.4.
I have had a good look through other posts but cannot find the answer. It does seem strange that cars of the same year have some different numbers and letters on the same part!

John go to any dealers as they will have this on record.

I wondered whether that would be the only option, cheers Brett. By the way, I am soooo jealous of the new car.

It looks like the fixed model. From the topic Warranty Extension: VSA Modulator Light on page 6, for TSB bulletin number SK-07-007-00 dated 01/11/2010 the revised part numbers of fixed VSA modules are;

Accord Diesel [CN1] : 57110-SEF-xxx
Accord Diesel [CN2] : 57110-SEG-xxx

Though yours matching suggests they've had the fixed VSA modules out for some time prior to the TSB. However if it's not broken, don't worry about it yet.
