Hmm came across this post which say you can open the boot manually with a screwdriver

viewtopic.php?f=11&t=2469&start=60

It's either a loose connection or a corroded wire.

There are some old posts on this website on this problem and it seems the only way to open the boot lid is damaging the trim to get to the lock.

Best take it to an auto electrician to identify where the fault is

This is illegal in the UK

Secondly you can't change the DLR as they are part of the headlamp unit.

Didn't they test the alternator when diagnosing the problem

I get front bumper sensors going off occasionally

As long as it's not permanent then nothing to worry about

try a station update

If that don't work back to dealer for a flash update

Take it back to the dealer and let them do it at no cost to you

Would deffo look at the 1.4t

Drove one today as a loan car and much quicker than my 1.4 n/a. Was the energy model with heated seats but no parking sensors and no fuel consumption display unlike mine.

Didn't like the stop start

Had mine serviced and MOT today

£30 for brake fluid change

Have you had the car from New?
