EGR problem?

[exec406]

Hi

Car is emitting white smoke at about 60 mph, car then loses acceleration as if in limp mode.

At 30mph car is fine driving around town(no white smoke), white smoke and lack of acceleration problem starts at higher speeds.

I recently had the EGR valve changed (a few months ago) Could this be a wiring issue? Car had a wiring repair done recently.

MOT is due soon although I believe the generic engine management light is an advisory (which I currently have)

Thanks

Re: above

Got the following codes from an OBDII reader:

P0487
P1113
P0087
P0193
U0122
P0234
P0461

The bottom code is 'pending fault' all others current.

P0461 must relate to the fuel gauge problem I have. From cold (usually overnight) it takes between 5-10 minutes to go from 'zero' to current fuel level. It then remains OK for the rest of the day.

Thanks
