What codes come up on the pedal test?

You can only clear the codes with TECH2 or other diagnostic tool. If the fault is not present, the TC light will go out and the fault will self-clear after a number of ignition on/off cycles.

Have you recently had any tyres replaced? Are they all the same size and profile? Are some brand new, whilst others near the wear limit?

the fronts are on the wear limit and will be replaced soon. the 4 tyres are all the same, the rears still have a good tread level on them, just the fronts that are low. (very low)

i thought disconnecting the battery for 30 mins cleared the fault codes??

the fault codes that come up are all to do with a very high speed run i had!! 02 sensor, fuel sensor (i think) after i slowed down the engine management light went out and car is fine, just got the codes still stored.

spoke to a chap at regal and he said the car proberly suffered fuel starvation, thats why it threw up these faults.

This is a common myth - some control units store the fault codes in memory that is retained even with the power off (like a USB memory stick). The faults will only clear with a diagnostic tool (like on the airbag system) or after a number of ignition on/off cycles. If the faults are not present, the emissions/TC light will not be on anyway, so no need to worry about getting them cleared.
