Hi All,

Randomly my alarm went off today whilst outside the house??

I unlocked and locked the car and it went off again, then I noticed the suspension was lifting and lowering on it's own, inside the car all sorts of weird things are happening, gauges running up and down, engine and trans failsafes showing Hi/Lo light flashing, dis lights flashing, park brake/oil and ignition lights all randomly flashing, I disconneted the battery for a few minutes and its the same, all the random stuff stops when it starts up.

Any Ideas???

Its been perfect up to now, but had a screen fitted yesterday??

How long do I leave it disconnected to clear the ECU??

Thanks.

With the battery disconnected, Check it's voltage with a multimeter. Cheers, Greg

The battery is Brand New at 12.8 volts (It's a month old)

Do a hard battery reset, Disconnect the live & earth and touch them together...

Thanks.

I’ve disconnected the battery. Left for 30 mins then shorted the leads. All seems ok at the moment. 😂😂😂😂😂😂

Bcm is dry.

MM, after a while the alarm has gone off again, I noticed the front air suspension lifting at the same time, none of the other faults this time??????

Ive pulled the alarm fuse for a moment to see.........

Anyone else have these issues before???

the bonnet switch is a common problem, clean it or disconnect it..... ... - .- -.

Thanks Stan, the switch was disconnected when I bought the car, its still disconnected now, but it is in the area where the windscreen guys were ???

you didnt mention the windscreen replacement in your original post..
theres an alarm sensor/light by the interior mirror and some other alarm stuff in that area so it sounds like they have possibly damaged something when they installed the screen.. ... - .- -.

If it's just had a windscreen fitted I'd be starting there.

I've seen it plenty of times where fitters cut through / shorted the wiring going to the rain sensor etc which will cause all sorts of issues.

It may even be leaking.

Hi Stan,

"Its been perfect up to now, but had a screen fitted yesterday??" was in the post.

They finished the screen at 1400 yesterday and things have been fine until this afternoon, drove and parked the car a few times last night ???

Do you know what items are up there???? I thought the alarm stuff was in the centre light console in the roof????

Thanks for any help ??

There's loads of wiring running up both a pillar trims and there's also quite a few running to the light / rain sensor at the top of the screen and also running to the rear view mirror

"Its been perfect up to now, but had a screen fitted yesterday??" was in the post.


cant recall that in your original post , maybe your edit confirms my suspicions .... ... - .- -.

Really Stan!! It was there probably edited some other grammar.

I think you have mis read my post Stan,"Last edited by colinwebster on 20th Jan 2018 2:50pm.

I have been a moderator on many forums over the years so Ill put your mistake down to professional pressure
