It really needs a diagnostic done to identify the actual fault codes present. If you can obtain the fault codes and put them up here with your VIN we may be able to advise.

The TPMS and the ESP system are linked, so that could be something like a wheel speed sensor.

Appears to need a new injector (no 2 - PSA number from the flywheel) - but I would clear the codes and see what comes back. Engine fault interrupts the data flow to the ABS which is why you get all the other lights. There doesn't appear to be any speed sensor codes - failure of wire to rear sensors is common these.

Hi Richard thanks for the reply,I had car plugged in and monitored the x4 speed sensors whilst driving all were pretty even but faults still present,whilst under bonnet I unplugged no2 inj (thinking it was no3) and engine ran even worse when I plugged it back in it didn’t come back to life so now 2 and 3 are off

Update
So,new injector fitted and coded to number 2 cylinder car now running smoothly again
All codes cleared and test drive down road monitoring the abs sensors and all were measuring equal,pulled into drive engine still running and two faults popped up please see screen shots for code numbers,can anyone shed any light on these two with particular reference to the steering communication fault

Has the battery got up to charge yet?
I've also had an additive pump error appear after an injector replacement (eolys)...

Hi yes the battery is back up to full voltage and is fine,have also been putting a trickle charger on it while I’m doing the scans etc to make sure it doesn’t play a part in the problems.
