57 reg, 1.8 petrol, problem is very strange.when I start vehicle, comes up with message handbrake fault,esp fault, injection fault. Car will only slightly rev up. Scanned with lexia accelerator pedal in live data all fine. Faults stored in engine,p1153 learning of initial settings of motor driven throttle. Abs, u1208 no comms with engine ecu. No faults in parking brake,bsi or any other module. Strange as it comes up with parking brake fault,but no fault codes stored. When this happens all messages come up together. The fault does not happen all the time,sometimes you start and it drives fine. I have replaced battery,and under bonnet fuse board . Can anyone help

Replace BSI in the engine compartement.
Probably a faulty relay had such issue with a HDI.

OFF TOPIC:-

Sadly never happened, but ALWAYS planned a 36 hour timer on a certain stwech wimo (guy had a wisp), to hoot the horn, as long as the job was something else of course.

Keep this quiet, but we REALLY DID put a supermarket trolly with no wheels in the trunk.

Update. Found water in one of engine ecu plugs. Common issue,temp sensor allows water to travel up loom into the plug. Going to replace sensor and clean ecu up,see how it goes .thanks for all help
