Dear all,

I just got a 928 S4 recently and not very familiar to the car yet... so would like some advice from you guys...

My central locking, or the door locks, seemed to be spoilt. The left door refuses to un-lock, and the right door refuses to lock. The central locking button did not light up too (it did light up previously). So what could be the cause of the problem? Any solution?

Thanks!

Mandy.

 

Hi Mandy - welcome to the pleasures of the 928 !
Not sure about your locking issue - but new owners are tempted to try all the ***** and buttons . One that could comprimise the locking system is one or both of the 1" rotary ***** at the upper back corner of the doors. These can "lock the locks", so I would first start there. A descriptive of their function is in the owners manual - which I haven't in front of me.
Anyway, try those first ...

 

There are two fuses located on the back side of the relay panel (which is behind the carpet and foot board in the pasenger footwell) that are related to the door lock mechanism. Check these fuses. The holders for these fuses are clipped behind the upper edge of the relay panel. They are not visible so you'll have to feel for them or get a small mirror and flashlight. Even though they may look fine, you need to test them with an ohm meter or just replace them with new. When one of these fuses goes bad, it causes the locks to start cycling back to the locked position.....it seems kind of stupid, but thats just the way it works. I'm sure there is some kind of ingenious logic behind it.
If it turns out that a burnt fuse is your problem, I don't think you can purchase these fuses at any ol' hardware store. You'll have to call or go to an electronics supply store. If your fuses are the same as the 86' model ( I think they are) then you will need 400mA (milliamp). My package of spare fuses says
Littelfuse (not Little, but Littel) T 400mA 218 Five Fuses. It is a package of five fuses and I think the 218 is part of their numbering system. They didn't cost very much.
Hope this helps; otherwise it might get hairy

Oh yeah........welcome to the 928 world! It can be addicting.

 

Hi Garth,

Yeah I'm still going through the manual.... Thanks for pointing out to me... Btw, nice wheel.

 

Hi JKelly,

Although I'm not sure if I can completely understand what you're saying, I'll ask my friend to help me out... Thanks for pointing out to me.

And you're right! The 928 is addictive! I thought I had so much fun with 931 (I still own one) but the Shark has shown me there is so much more fun with the power! There is (the car) just so much presence on the road!
