Omega General Help / Re: Serious Judder on Braking at 60+

« on: 16 November 2008, 22:03:51 »

I'm with cem. Stay with the brakes. The steering is just telling you something is wrong.
Check your caliper is free to move and that the free pad is not binding on corrosion on the caliper, causing braking force on only one side of the disc.
One problem I had once on old 5 series was caused by taking too long to change out a bad disc, which didnt cure the problem, because the hub and bearings had become damaged, although the bearing still felt good when you spun the wheel. Just when the load went back on the bearing it caused the vibration on braking.

Omega General Help / Re: Where can I get some good info for H+V problem

Some progress
Found a solenoid valve on LH of ECC unit. Took out glove box for access. (Quite easy as the last person here saved some time by not refitting any screws) Power to the solenoid but it wasn't opening. Bypassed the valve and this closed the HBP so I got some heat.  
Next I checked the other solenoid valve which operates the recirc flap. It too was knackered so it was bypassed to allow fresh air into the system.
Does anybody here sell these solenoid units or do I need to go to the rob-dogs?

Not out of the woods yet because the windscreen is misting down now. Not getting any force of air through the windscreen demister grille. When I press the demist button the fan goes to full speed but most of the air comes out a great gap at the back of the blower fan into the passenger footwell. I have a distinct feeling this shouldnt happen and that there is a bit of pipework/ damper missing. I will probably need a look at another vehicle to see whats what with this. Any thoughts ?  

Regards Steve

Thanks for replies.
Got a Haynes manual and had a go, although not really got much out the manual yet.
Found that the coolant leak was coming from a crappy t-piece which has been installed before the heater bypass valve. This feeds the LPG vapouriser. The bore of the Tee was only 8mm so got a better one 12mm bore, believe it or not from halfords, usually they dont keep useful things.
I also cleaned out the bypass valve. All looks ok here and reassembled, filled the coolant and warmed up.
Now I have seen the bypass valve I can see that it is spring held in the bypass position and needs vacuum on the diaphram to open it to the heater.
When I felt the bulkhead heater connections they were not hot, so I disconnected the vacuum tube and there was no sooking. Couldnt find much in the manual about the vacuum but there is a drawing for the ECC so once I find a magnifying glass I will follow the tags to see if there is a electrovacuum valve somewhere. I guess I'll find some pipe has become disconnected, squashed broken behind the facia
Ran out of daylight for today and I need to graft some skin back onto my hands and wrists. Must be a smiley for that somewhere.  [smiley=vrolijk_26.gif]

Omega General Help / Where can I get some good info for H+V problem

I recently bought a Y reg 2.2 CD Auto because it had LPG and it was cheap and I like the Omega shape/comfort. The LPG works but there are a load of problems that you can't see when you just want to buy something. There is no history or owners booklet. I bought a workshop CD from Ebay which is as much use as a chocolate teapot. Maybe one of them is genuinely useful?  The Haynes manual doesnt cover the car datewise unless someone tell me different so I didnt buy it. I really need a decent electrical drawing. (which I was looking for when I stumbled on this site)
Main thing I need to fix soon is the climate control, which doesnt heat or cool. Display lights, fan runs according to difference from set point but not much force of air at the outlets. havent had any heat since the "summer" when i didnt ask for it or need it. When the ignition is switched off you can hear a damper close/open. Slow water leak from some gadget down the righthand side of the engine so I keep topping up and am not discounting the possibility that at sometime the system ran empty and the heater is airlocked. But until I can get some info i am just guessing.
Thanks in anticipation. Steve
