Question Cannot lock the back doors with the key.

Hello,

I cannot lock and unlock the back doors. they work normally but they just can't be locked. Also the tailgate acts strange. normally it cannot be opened by the electric button at the door, but it can be opened by the key anytime. When the car has moved for a while(ex.after a trip) the button can open the tailgate. I think it is an electric issue but I'm not that sure. your help will be appreciated.

Re: Cannot lock the back doors with the key.

Hi,
Does sould like a loose connection. Most likely areas are the body computer / Junction box behind the little cubby box (by the drivers knee on right hand drive) in the dash. Second is the junction box in the luggage compartment. You can download the eLearn eletronic manual system from the forum. This has location diagrams.
Loosen each plugs, relays and fuses and push them back in (one at a time).

Re: Cannot lock the back doors with the key.

Hi,

I had always had a similar problem with the tailgate only sometimes opening with the remote. The same with the button on the latch. I normally found that by locking the car and then unlocking it, the remote would work on the tailgate again.

Someone around the forums said that this may have been an earlier software problem that was fixed in later upgrades.

It didn't seem worth the expense to have the software upgraded so I lived with this anomaly for quite a while.

Recently (see other threads) I have had Ignition, Steering Lock and Body computer replaced. Apart from my car now working just like it did before all the problems, my tailgate locks and unlocks, opens and closes as expected using either fob or fingers.

Only cost about a grand to get that one enhancement!

Regards

Gaz
