Locking, and MPG issue

[wrayvon]

Morning folks,

Got a couple of issues at the moment.

The first is my locking. The car auto locks at 5mph ish as you all know, but then the passenger side unlocks itself straight away. When I press unlock and lock again, sometimes it stays locked. I'm guessing an issue with the locking mechanism, but has anyone got any ideas how to fix it?

The second is my MPG. It has been a lot lower than normal for the past couple of months. E.g normally driving to work I get around 70mpg. Now I'm lucky to get 55. The only thing that has changed is it has been de-cat. Would this make that much difference?

I realise there probably isn't much to go on, but any help will be most appreciated.

Thanks

U Checked your air filter recently?

 

[wrayvon]

It was changed approximately 3k ago, so should be ok really!

Fuel filter, Faulty injector?

 

[wrayvon]

Not changed the fuel filter for a while, I'll get that done this weekend. Not sure how to test for a faulty injector though.

Thanks

Used to have the same "locking" issue with an altea, fixed it quickly by putting window down and with door closed pull the interior handle at the same time as pulling the exterior handle, took a couple of goes but eventually felt a click on the handles and it reset the lock mechanism.
Hope it helps.

MPG wise your going to notice a drop off as the weather gets colder and the car takes longer to warm up. Unless it was very sudden I would be happy with 55 mpg in the winter.

Tried this at the weekend, unfortunately hasn't worked. I did notice though when I open the passenger side the interior light doesn't come on. So perhaps something else is amiss?

I'm happy with getting 55 in winter, but it's been at this level for a few months now, i.e when it was warm

Replaced the fuel filter, doesn't appear to have much if any difference. Darn

Any other suggestions folks?

Thanks again

 

[WATSON]

injector would be only other thing i could think of

Sounds like you need a door lock mechanism. Generic part on eBay is about £40, genuine one about £120 IIRC. It is a job that's possible to do at home if you have the tools and know how, quite fiddly but not overly difficult.

A faulty temp sensor is a common fault and can also cause bad MPG. Have you had the car scanned for faults?

 

[wrayvon]

Not even thought about scanning! Haha thanks I'll do that tonight.

Lock mechanism makes sense. I'll get researching it, thanks, that's really helpful

 

[wrayvon]

Unfortunately, or fortunately(?) there were no codes when I scanned it yesterday. I may replace the sensor though, as they are pretty cheap so worth a try!

I shall let you know if anything improves!

Hi mate, I recently replaced the door lock mech and I found this very helpful...

There is one thing I found that wasn't in there though, when you take the inner metal door card off, the reason you need to pull it to the front of the car (towards the door hinges) is because there is a clip that slides in and out of the door mechanism unit which is a bit awkward to remove so needs a bit of a tug also its a bit of a bitch to get back in when replacing the metal door card to line up the bolt holes...other than this it was a brilliant guide!

Hope you find it useful
