Omega General Help / Re: Another Remote Locking Fault

« on: 16 March 2025, 16:13:41 »

Have you tried the remote locking in a different location?

It could be a local interference issue.

Yup, everywhere. In car, out of car, near home, 100km from home, left of car, right of car.

Would the leds still work if the pins are snapped? I measured voltage on the solder blobs of the pins and also got 3.1V. I guess I could fiddle around with it and see if the pins don't give contact when the fob is assembled..

So, for a while I had the fob working very well. The resoldering and new battery worked wonders and opened the car from about 10 meters away. One day though it stopped working again. No cold solder joints seen this time, the car just does not respond to fob button presses.

Tried to re-teach the car with ignition on - it doesn't respond at all.

The fob battery is rather new, voltage 3,1V, the leds on the fob light up brightly. What and how to check?

Omega General Help / Rear doors won't open from the outside, any suggestions to solve?

« on: 29 January 2025, 23:47:03 »

Opel Omega 97 pfl sedan

When I bought the car, I even admired how the doors so gracefully and easily operated, the click of the handle and the sharp pleasant closing sound. With the colder weather arriving the pleasant door handle sound was replaced by a pathetic "thump" and now I have a two door Omega.

However both rear doors open well from the inside. The passenger side rear door doesn't open at all from the outside handle, the driver rear door opens when Mrs. Omega has a good mood.

A local guy mentioned something about pushing on the door while opening, and today I tried it and got both doors open from the outside. It's not a satisfactory solution and I still look like a car robber when messing around with the handles.

Is this a common issue (I've heard it is) and what can be done to better it?

TIA.

Thanks man! An obvious problem looks like, but can you explain to me how do you get p0335 from 10,3,3,5? 10 = p0?

So post 1995 cars use an RF fob with a rolling code system.

If it stops working, and has to be resync'd to get it to work, its likely it's losing where it is in it's rolling code.  A few possibilities:

Knackered battery holder, particularly where the battery holder pins go into the PCB. Seems to afflict the integrated horseshoe style keys more than the separate fob type.

Yesterday I examined the fob and correct, a massive cold joint of the negative terminal. The battery was also only 2.7V. Fixed it and now a well working fob so far, even though I'd like to change it to something cleaner and sturdier. Many thanks!

Omega General Help / Help decoding paperclip test: 97 pfl X20XEV Opel Omega simtec

Hello

I'd like to ask for some assistance in decoding my EML flashes from paperclip test. I followed the advice given here in this older topic:
https://www.omegaowners.com/forum/index.php?topic=90581.0

I recorded a video of the test:
https://www.youtube.com/watch?v=yc6ZcBpd5Kg

As stated in the video the car is 97 pfl X20XEV Opel, has a simtec 56 ECU manufactured in october of 96. That's all I know.

How can I exactly decode the flashes?
What I'm seeing is that it flashes only:
10
3
3
5

...over and over again and nothing else.

The car has been suffering from starting problems occasionally and last night I drove it for maybe 10km with the AC on HI and full blast and the temperature was rising to near 100C. When I noticed it I immediately shut off the AC. It fell down to 95-97C. Today it was about 95C. The coolant is near the "kalt" line if hot. Will check the level when it has cooled down. A significant problem?

I live in Estonia and right now there's a lot of snow and the temperature outside is -5C if that's important. The service i went to in october put in GM 5w-30 oil if that's important.

Omega General Help / Another Remote Locking Fault

« on: 18 December 2024, 23:11:12 »

Hi, totally new user here from Estonia, having the same issue here in 2024 in my Opel Omega 1997 pfl. The remote works for 2-3 times and then the car forgets it so I have to reprogram it again. Does anyone know if the author found a solution back in the day or what it could be? I can see from the leds that the fob is operating. I was wondering if there could be any fuses related to the system. I also have a problem seldom but still that the car is cranking but doesn't start. Fixed with locking the car 1-2 times.
