Poorly 1.8 Tdci

Hi all,

Got an 09 plate Focus 1.8 TDCI and this morning the ESP lights come on and remained on for 200 miles. I've turned car off and back on, but the light still remains. I'm guessing that this is down to a sensor at one of the wheels, but what i don't understand is that at practically the same time, every time i foot my foot on the accelerator (when the car is moving) and apply ANY degree of pressure, the car violently lurches as if it's been hit from behind and then carries on accelerating as normal? Also, coming down the motorway this morning, the cabin STUNK of fumes.

I'm guessing the last two are not connected to the ESP light, but has anyone any ideas whats going on??

I've just had the codes read and i'm getting -

U1900 - Apparently i can ignore this one?

P0704 - Clutch switch (my fault, was kinda expecting this one)

U2023 - Unknown??

I've Googled the last one and i'm a bit confused. Apparently this could be an ABS sensor, but at the same time, as the ESP is lit and remain on this could be a hose between turbo and intercooler.. Could anyone offer any advise to try and define which one it could be? I'm kinda thinking the hose makes sense, as it makes a whistley noise, immediate area around car when it's running STINKS and last couple of days, the jerkiness when putting foot on accelerator when moving off from a crawl is just unbelievably bad!

Cheers!
