PD 130, cold missfire, ESP & Glowplug warning light flashing

[Giblet]

Hi guys,

had my car now since Tuesday "02 reg B5.5 sport Estate" with 92k and it's already causing me to regret buying it.

First day ran fine no issues when I picked it up and drove the 35miles home. Finished night shift and as I'm driving home the ESP light came on followed shortly by the glow plug light flashing at me. This continued for a couple of miles to flash and then eventually turned it self off.

So when I got up later that day and went for a test drive no issues. Same thing happened again after I left work, ESP and Glow plug warning light.

Tonight I've got in the car and there was what felt like a missfire. It was cold as I'd not used it since 0630 this morning. Increased the engine speed and no missfire present. Dropped back to idle and all was Ok, same issue on my way to work ESP and glowplug light.

So in summary:

Cold missfire for a few seconds
ESP Light on
Glow Plug light Flashing,

I'm half tempted to try and get a refund on the car as I've only had it since Tuesday.

And help/advice would be much appreciated.
