Evenin' everyone.

I've a list of faults that I have listed below in the hope that they are all (or most) connected in some way.

Heater/Climate: Blows hot on drivers side and freezing on passenger side.

Airbag light: Stays on all the time.

Alarm: Goes off a few minutes after arming, so having to leave car unlocked on the road.

Gearbox: Long story. Started jumping and clunking a few years ago and then limp mode. Turn off, start back up and out of limp mode but still jump/clunk.

Had new switch fitted (2 yrs ago) at main dealers to cure problem (£350) but it failed to remedy the problems. Got refund (not sure if they removed switch because I think they may have binned my original one).

Had ATF and filter changed last month and slight improvement but gearbox is still misbehaving. Sometimes the clunk feels like huge hammer has whacked the car from underneath.

Had car from 1yr old, 17k miles (ex-vauxhall). Full VXSH until last service by a local garage. Car has now covered 98k.

Some of the problems will be my fault. Let her stand for 2yrs and only ran her 10 times in that time due to crank sensor fault (now fixed) so couldn't get started a lot of the time and therefore dampness got to the interior.

She's a good old bird who's been a grand servant and in great nick for her age and I don't want to lose her if I can help it.

Any help greatly appreciated.

Many thanks.

Paul.

heater - check servo arm for passenger blend flap

airbag - needs checking with proper diags

alarm - bonnet switch is common. Unplug, then see what happens

gearbox - could be anything, what engine is it bolted to?

This should sort your heater problem:

Check your bonnet switch and make sure it is seating properly, one of the most common reasons for the alarm activating.

Thanks for the info, sounds promising.

Engine number from VX Car Pass = X30XE /08338812.

Cheers,

Paul.

Thanks for the info, looks to be the likely cause.

The 3.0l isn't known for eating its AR35 autobox, so check fluid level is perfect, then you are in the realms of looking further.

A full description of exacly when it happens will help the experts here offer advice on what could be causing it...

when my selector switched oppsed up earlier in the week the gearbox was bangin clunkin from 1st to 3rd, and makin some strange noises, try cleanin it out, its not that hard of a job just one side (passenger side) up high and do it when exhaust is cold, watch out for sharp bits on exhaust im still wearin the scar's.

Good luck and hope you get it all sorted soon

PS look for auto box problems  in general help, i started a topic

The fluid level should be spot on.This and the filter was changed a month ago along with a good clean out (nothing too bad just the usual grey sludge).

If the car is ever going to misbehave it is when "sport" is selected. In this case, if floored it will pick up okay but will sometimes redline and fail to change up from 3-4th or 4-5th unless you take your foot off the gas. Again in sport mode a clunk/jump can be felt between 2-3rd with the engine spinning in limbo until the gear is found and then "WHACK".

Also in sport, gentle deceleration when approaching lights/junction can result in a huge whack when downchanging from 3-2nd.

I trust the guys who did the ATF and filter change and the car behaves pretty much the same as before the change except the changes are smoother.

Took her out this morning (not in sport), freezing and she was as good as gold even though she was hard driven on the salted empty bypass.

Any clues would be great.

Thanks.

Paul.

Sounds like a dodgy 2-3 solenoid in the box. Easy enough to change with the sump off

Thanks for that.

I'm sure the box is clean after the ATF/filter change (the guys who did this are very good). Maybe the selector switch you talk about is the same switch my VX dealer put on the car a few years ago without success?

Thanks for the replies everyone.

Thanks Rob. Any idea of the cost of the part?

[RobG]

PM "unlucky Alf" he will have a better idea http://www.omegaowners.com/forum/YaBB.pl?action=viewprofile;username=33273A32322C550

after another read sonds like a completely different fault to wat i had

[Paul T.]

Thanks The Boy & Kneepad. Disconnected the bonnet switch and the alarm is no longer misbehaving. I'll have a look see if it is seated properly tomorrow. 

Central locking has gone out of sync today though. N/S front door permanently locked at the moment.  Any ideas again please. 

[Kneepad]

Glad to hear you silenced the alarm.   


Try  a re-sync with the key in, ign on, press lock then unlock on the fob.
Failing that, I suspect the central locking solenoid in the drivers door has failed.
