I have a 2002 Vectra C car. Just wondering if someone can help me out - I went to do an MOT test a couple of days ago, but it was a failure because the nearside rear door wouldn't open at all (Happened all of a sudden and the new 2012 MOT rules say that you have to be able to open both rear doors from outside).

If you use the key fob, pressing the "unlock" button opens just the drivers door. If you press it twice, it opens all doors, but the nearside rear door stays locked and you can't open it from inside or outside. Finding someone to fix it is a nightmare because it's the Christmas period. However, when I was messing around with the central locking today, I noticed that if you just press the key fob once to unlock the drivers door, put your hand inside the car and manually unlock the car from inside, you can open the rear door from both inside and outside and the door works as normal but if you lock it again using the key fob then unlock it, it won't open. The rear door only opens if it's manually unlocked from the inside. It's a very strange problem but because I have to get a new tax disc tomorrow, I'm wondering if the mechanic will pass it considering the rear door can be opened that way from outside?

Its to do with passenger safety is if you crash they might not be able to get out and emergency crews might not be able to get in. I wouldn't have thought they'd pass it for that reason alone.

If you present it unlocked for a retest it should pass as the tester can now open the door.

Ask him, simple as that.

and it sounds like your solanoid has failed (could be a wire, could be mechanical, but is usually the solanoid).

Leave the car unlocked? Or fix it - doesn't sound like a difficult job smile

Take the door card off, undo the connector for the central locking, put the door card back on.

Just remember to lock it manually when it's not in use

Don't lock it when presenting the car for testing. Give instructions not to lock the car. Vehicle must be tested as presented.

I can't swear to a Vauxhall, but that wouldn't work on a BMW, it would know and bounce the locking !

It's nothing to do with the new 2012 rules, it's always been that way.

Rear doors have to open from the outside and front doors from both outside and inside.

I suspect rear doors not having to open from the inside is due to childlocks.

As others have already said, present the car unlocked and you should be fine.

Take the inside door card off and remove the lock completely, dont risk the car locking itself and the mechanic not being able to open the rear door. Even if you tell them its unlocked they might press the fob and lock it, then unlock it, anyway before driving it in. It'll fail if you cant open the door, it wont fail if you cant lock the door.

Similar in princable to the fact that it is illegal to have a bald spare tyre but not illegal to have no spare tyre.

Didn't think it was a part of the test.
It could be an advisory so the owner knows I guess.

If he removes the mechanism there will be nothing to hold the door closed.

Indeed - the spare tyre is not tested but it can be noted as a courtesy to the owner.

I had this exact rear door problem at the very moment I was handing the keys over to the guy who was buying my Vectra! Seriously!

Except no matter what I did the damn thing wouldn't unlock!

I ended up pulling the interior panel off (which is a challenge with the door locked shut!) I then had to smash the lock unit to pieces (a 40 minute task with a 1/2" socket extension fed inside the door swinging a hammer in the small space left available) to get it open and replaced it with a new one so that I could sell the bloody car!!!

If I were you, I would replace it while it's open/unlocked?!

It isnt a part of the test, no. Its just illegal to carry a bald spare.

I dont mean the entire mechanism, usually the locks and the catch/latch can be removed independently of one another. Like when a door fails to lock due to a fault in the central locking system, the doors can still be opened and shut, just not locked.

I await to be corrected sir, but I think that is "pub law", common sense but taiters, I think it doesn't become a sick bird until you actually fit it to a car on a public highway.

It comes as a complete unit, the locking action is built into the mechanism.
