Hornby 4-VEP Problems

[43021HST]

About 10 days ago I purchased a Hornby 4-VEP in NSE livery from E-hattons. The Unit is DCC fitted, despite my layout being analogue, all I could find on the website was DCC fitted units.
Well the VEP has a few problems, it seems to run fine in one direction, but then it simply refuses to run in the other and stopping and starting is not as smooth as most present day models.

I don't know whether it's because I'm running a DCC fitted train on an analogue layout or if mechanically its a bit dodgy. I was pretty sure you could run DCC fitted stock on an analogue layout fine.
If it is due to the fact I'm running a DCC train on a DC layout, then does anyone know how to de-activate the DCC chip or remove it?

The chip connects via a simple connector.
If you open the correct carriage (Can't remember which) you can disconnect it.

Look on Google/Youtube for instructions on adding the chip.
Do the reverse.

Hornby 'DCC Fitted' trains should work fine on DC, though they may react slightly more slowly than 'DCC Ready' models. If you suspect it is the decoder, you can remove it as noted, but you will need a 'blanking plug' to get the electrics connected up, I don't know if the 'DCC Fitted' models come with a spare (I suspect not). If you simply remove the decoder the model will not work.
