Omega General Help / x20xev eml on

« on: 05 April 2019, 23:00:25 »

1994 Omega 2,0 16v eml stayed on one morning, and have been on since. No coming and going just always on. Did the paperclip test and got codes 38 and 91. 38 being a faultcode for the o2 sensor, and 91 being the o2sensors heater element. Have not had much time to look at it yet but was underneath the car and checked the connector for the sensor which looked fine. Also wiring in the area from connector on gearbox to sensor looked intact. Never had this fault before but suspects an o2 sensor fault code can be caused by other things too. But im thinking that the sensor heater fault code would point to either defective wiring or defective sensor? And that the code 38 for the sensor itself is just a result of the heater not working so that the sensor fails its readings due to not reaching operating temperature? Can the heater in the sensor be checked by Ohm meter, and what readings am i looking for?

Omega Electrical and Audio Help / Light bulb in light switch

« on: 08 March 2019, 07:51:14 »

There is a little light bulb in the back of the main light switch. 12v 0,5w with a small plastic base. Smaller than the instrument lights. Gm90511962. Where do people get hold of this? Cant really find online and the local Opel dealer said it was out of stock in Norway, «local» storage in sweden and main storage in Germany. Is there any other bulbs that fit? Maybe get 0,5w bulb without base and solder it in an old bulb base? Opel dealer send a request for me but im not holding my breath.

Omega Electrical and Audio Help / Retrofitting radio controls on steering wheel

« on: 06 March 2019, 21:58:52 »

Thinking of retrofitting radio controls on the steering wheel in a 1994 Omega. The wiring itself i believe i have under control, but the issue is that the 1994 and 1995 Omegas have a different steering wheel than the newer pfl Omegas. Also these early cars never had the remote control option. This means i have to change the entire wheel to one from a 1996-1999 car. This also means that my current airbag wont fit and i need to use the airbag from the new wheel which i will probably get from eBay.
But im unsure if this is safe to use an unknown airbag? If i change the wheel and the airbag and the airbag light goes out as it should does this mean the new bag is ok? Or is it anybodys guess.
The other option would be to try and modify the existing wheel to fit the remote switches.

General Car Chat / Omega Pfl manual heater controls

« on: 05 February 2019, 06:56:03 »

This is not a request for help, more a general rant/complaint. I’ve driven Omegas and little else for the past 10 years but only 94-95 cars. (Opel sold a lot of Omegas in the early years in Norway). We currently run a fleet of 3 Omegas. I drive one, my girlfriend another and a third serves AS backup vehicle in case some problem should happen with one of the others. The last car i bought this summer was a 97 pfl Omega and at first glance it looked identical to the 94-95 cars but when winter set in it was apparent that it had differences in the heater controls.
The early cars have a fan switch that ranges from 0-4. And a heater direction switch that in the extreme right position directs all air to the windshield. These work well in Norways cold winters (-20c). You turn every switch to the extreme right to melt the ice on the windshield and once the car has warmed up you turn the direction switch to the symbol for windshield and floor and get a Nice distribution of air to the windshield, floor and the side vents.
However the 97 car had a fan switch ranging from 0-5. And the direction switch is completely different too. Windscreen air on this is switch straight up. Could live with this if it wasnt for it behaving completely different too. When the car is warmed up i turn the switch to the symbol for windscreen and floor, but unlike the earlier cars this one then dont distribute any air to the side windows. Side windows will then fog/freeze and i must turn the dial to side windows and get a lot of air out the side vents, but only those. So i must pay attention and quickly turn back to the front windshield once the sides are clear. Otherwise the windscreen freezes.

So to the rant: why would Opel change the manual heater controls that seemed to work fine, with a setup that obviously dont work fine? In the later(97) setup there is no way to keep the windscreen and side windows ice free at the same time while not freezing your feet of in -20c weather. 94-95 cars dont have this problem.

Omega Electrical and Audio Help / Omega hit by truck - what triggered the alarm

« on: 03 January 2019, 11:19:43 »

One of my Omegas was hit by a truck yesterday. Driver of course ran away. Know the identity of truck and driver so hopefully the company will tale responibility for the damage today. Omega was parked and was hit in the rear by what i believe is the trucks rear end swinging out when turning. Omega is a 97 estate. Trucks rear steel bumper ripped a big hole in the omegas plastic bumper. Also hit the Omegas trailer hitch and dragged it 40 cm sideways. The Edge of the»box» on the truck went through the Omegas tailgate window wich shattered in a thousand pieces. Tailgate itself seems pratically undamaged.
Omega alarm was screaming and flashing. But started thinking, what exactly set it of. Glass break sensors on the rear side windows only cover their respective window i assume? Also didnt think the omega alarm would react to the car moving sideways? Tailgate structure itself is intact and remained close. My assumption is the interior Motion detectors triggered the alarm when they reacted to pieces of the tailgate glass started flyging around in there. Or is it any other feature on the alarm that could have reacted?

General Car Chat / Resyncing ir remote helps with range/reaction?

« on: 27 November 2018, 16:47:48 »

Hi. Of my 3 Omegas 2 have the old infrared remote Control system. A 95 car thats in daily use had recently started getting difficult to unlock. Assumed remote battery, but changed that with no effect. Had to keep remote right up to the window and push the button 5-10 times before the car reacted. Remote was bought new from Opel (and programmed)  some years back so its in far better condition than the original 94-95 remotes. First thought was that either the remote or the receiver in the car was starting to fail. But tried resyncing it with ignition on and remote close to the dome in the roof. Car reacted as it should by flashing the interior light. Much to my surprise the remote worked just fine afterwards. Car unlocks/locks on the first push of the button.
Always thought that either the remote was in sync or out of sync so to speak. That it either would work or not work. Can anyone explain why a ir remote that only works like 1 of 10 pushes after resyncronising suddenly works every time? Can they fall partly out of sync?

Omega General Help / Omega 2,0 16v Pressure in cam cover and oil leak

« on: 06 October 2018, 11:21:28 »

Hi. My 2.0 16v has lately developed the classic symptoms of cam cover failure. Misfire on idle and smell of burning oil. Checked and all plug holes were full of oil. Also oil drips down on the exhaust heat shield. Disconnected the smaller breather hose and thats got a good suction in the hose. What i dont get is that the pressure seems to be high in the cam cover? Removing the oil filler lid with the engine running reveals alot of pressure coming from the filler hole. Dont know what kind of pressure should be there but this seems excessive and i can easily see this helping blowing the oil out every which way. Dont feel any pressure being released through the small pipe where the smaller breather line connects. But AS said. This line has good suction when disconnected.
Any ideas whats causing this pressure in the cam cover?

Omega Electrical and Audio Help / Rear wiper motor stuck

« on: 18 September 2018, 20:33:04 »

Hi
Im strugling with the rear wiper on my 95 estate. It started slowing down and stopping before it finally stopped working alltogether. Got 2 different motors from ebay now, but both og them where also stuck. The motors just click and try to move but cant. Tried connecting them straight to a battery to rule out poor wiring but still just a click from all of them. Everyone i see online also seems to have a fair amount of rust around the spindle. These are built like a not servicable item and are bolted together with no easy way of getting them opened. In desperation i took an Angle grinder and cut the bolt heads of one of the mechansims to get to the gearbox inside. Everything looked fine with plenty of grease in there. My theory is that its the spindle itself that gets stuck in rust.
Have Anybody succesfully ressurected one of these? Or can a rear wiper mechanism from a newer Opel/Vauxhall be modified to fit? As all the omega rear wiper motors out there seems to be really past their prime:p

Omega General Help / Rev counter and fuel gauge jumping up and down

« on: 24 August 2018, 18:23:34 »

Hi. Finally picked up the 94 mv6 today. Its been sitting at the welders shop for over a year. First 5 min after startup the rev counter and fuel gauge would jump up and down between zero and actual reading. Engine ran fine the whole time. After the car had been running for a while they worked fine. Tried starting it again when i got home and the needles jumped up and down a few times only this time before settling. Figured it must be a instrument cluster problem since i Cant see any other issue that would affect both fuel gauge and rev counter in the same way? Engine temp and speedo worked fine. Can the fant that the car has stood over a year without power on the battery cause this?

Omega Gallery / 97 omega gl estate «winter car»

« on: 22 July 2018, 20:21:19 »

Thought i show off my new third omega. Got a 95 mv6 estate from earlier (Opel version of the elite), and girlfriend got a 94 omega saloon. Since both the other omegas are currently away on rust welding repairs i got this one cheap to use on Norways winter roads with tons of salt on them. To save the newly welded mv6 from more rust. Norway is a hard country for old cars:p
Anyway the car had one owner from new until i bought it now. A 87 year old man who passed away this spring. Bought the car from his daughter. Car has only done 60.000km in 21 years! Unfortunatly the previous owner never really washed or polished it so rust has taken its toll on all doors and rear arches.

Here is the car when i got it. Notice the green license plates. These are «van-plates» which where a kind of loophole in the law when the omega was new. This meant you could save maybe like 100.000,- nok(10.000gbp) by ordering your car AS a «van». This meant you could not have a back seat.

Dividing steel wall is bolted to the folded down seat back. Also a steel plate coversanger the rear seat back.
Allthough the car is a little rough around the edges its probably the closest i will ever get to a «new» omega. Its very Nice to drive with only 60.000kms on the clock. Allthoug it does seem a bit more gutless than girlfriends saloon with the same 2,0 16v engine.

Omega General Help / Remove sound insulation

« on: 29 April 2018, 14:01:22 »

Hi. Im stripping out the interior in a 94 omega sedan to get it ready for som rust welding next week. Got all the seats/carpets/centre console out and the sound insulation mats in the floor except the front foam mats. Seems to me that this front foam insulation mat is one big piece from a pillar to a pillar and from just in front of the front seats to a good way up the bulkhead behind the dash. What is the best approach to remove this mat? Seems to me that to Get it out in one piece requires the dash and much of the wiring loom to be removed. Leaning towards just cutting the mat up in removable pieces.
Any experiences about this?

Omega General Help / Inner rear wheel arches

« on: 08 August 2017, 15:55:57 »

Need new inner rear wheel arches for my 95 omega estate due to rust. Veng used to have these with partnumber 5040541 and 5040542 for the left and right side. But they are now discontinued. Are there any stores/sites that still have these in stock and ships to norway?

Omega General Help / Omega pfl white paint

« on: 06 August 2017, 10:12:46 »

I am changing a front wing on my 94 pfl saloon. The car is Casablanca weiss colour. Got a used rust free wing in white but on closer inspection the new wing is more yellowish/offwhite in colour while the car is brilliant white. Are there different white colours on the pfl omega or have the new wing just faded somehow? And if so can you Get the really white colour back somehow?
