hello all, I hope somebody can help solve some gremlins.
I will try not to make it to heavy going as I dont want to be a bore.

So here goes:
1) cant open top glass on tailgate, just wont budge. Dodgy switch?
2) parking sensors not working, long continuos beep and red light flashing on switch, Parking sensor failed or could it be something worse?
3) When i turn key in ignition, engine turns twice then stops, starter motor?
OH, sorry I said 3 but there is one more: trip computer keeps resetting itelf, could this be related to the poor starting and be indicative of an alternator or battery problem?

Should have said the car is a 3.6 tdv8 2007

Any help greatly appreciated, I love my Rangie but Im going off of it a bit

just had RAC man here for the poor starting problem, turns out the battery is only half charged, so not holding it properly, he offered to change it for £137-00 for a Varta battery, Im beginning to think it was not such a terrible price and I hope I dont regret it in the morning.

Im hoping that this is also the answer to the trip pooter problem.

Could still do with some advice on the sensors and tailgate problems?

Tailgate problem could be due to internal corrosion of the lock mechanism, both my RRS1's had to have a new rubbery opener cover as it had perished but also condensation can form in between the two panels of the upper opening section and this trickles down to the lock area causing the lock to corrode. 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Also in my garage is a 1996 TDi300 Defender 90 County HT made into a fake CSW

I fitted one of these to my old HSE which is identical to the original but more power.
So far it's been great, I can't fault them.
