Hi Lads,
Just had my aircon gassed up by KF. Before the re-gas it was blowing warm moist air and since it has been blowing cold, but not that cold.
The chap at KF measured the aircon temp through one of the vents and after a few mins the temp dropped to 10 degrees, which i thought was ok.
Since then i drove to brummy and back and i wasn't too chuffed with the aircon peformance TBH. If i set both sides to LO and A it was cool but not as cool as lets say the fonze!
It is possible that the KF guy didn't do a good job or could my aircon need a Tech2?
I might go back to KF but i will wait on OOF just in case...
Cheers

Do they have particulate filters like the Peugeot 206???
Had my car regassed cos it was running warm, didnt really do anything...a specialist garage I spoke to said change the filter, thats the problem...I washed it and ice cold air...
-
Omega with climate control certainly has a filter/dryer ..... I know .. I saw the crap that came out of mine after the compressor failed .. :(
-
Bingo... Thats something i can do for free on my drive now!
I like the words FREE and CHEAP ;D
PS: Where is the filter? Not too sure if haynes would cover an aircon system, but i'll just have a look.
Thanks anyway :)
-
My climate aint anything special either.......
But worth checking pollen filter......if its blocked could be restricting airflow....
I can measure 5C with a probe shoved down the centre airvents.......but that is with it on manual, set to LO and fan speed on 2 or 3 ......leave it on auto and it carnt get anywhere close to that temp.
When on auto and say set to 18C its not that cold and fans run on max speed.....in this weather were having.
Also maybe worth getting climate ecu update to latest firmware......ive heard that does improve things.......having said that mines at the latest firmware.
-
I have exactly the same issue with mine. Cooling to about 10-12 degrees but not that special (gassed at KF last year). Was having a look at it today and noticed that I have piping hot plumbing to the heater matrix when set on LO so I'll be investigating the operation of the HBV next I think.

The pollen filter is under a flap rhs scuttle area :y
Entwood is taking about summat else.......and not summat you can do.....well at least not without getting it regassed again.....
-
is it the pollen filterr your on about ? if so it lives on the left hand bottom side of the windscreen under a plastic "scuttle" panel very easy todo lift the plastic cover off gentely then its under there undo the two clips i hovered all mine up with my mrs's hover and then sprayerd it with oust and put it back in and hey presto jobs a goodun!
-
The pollen filter is just like an engine air filter except it takes the 'pollen' bit out of the air before its fed into the car cabin.
The filter/dryer referred to is to filter and dry the aircon refridgerant within an enclosed aircon system and thus is not rutinely servicable without a complete dgas and clean of the component parts....
-
If the pollen filter was blocked and restricting airflow surely the small amount of air coming in would be even colder ??? - or am I being a numpty ??
I accept the filter/dryer is not a "quick fix" but it was the first thing the specalists went for with my problem. Apparently this should be changed every 2 years, but because it needs a de-gas rarely is. The symptoms I had - either a filter/dryer or a stuck expansion valve - needed a de-gas anyway so they suggested a filter/dryer change anyway ... it was when they removed it they found all the horrible gunge .. :(

Darn it! the cheap and free bit didn't last long >:(
Kev - I just installed a new HBV as it was leaking, so i will tick that off my check list. One thing that might be a cause for concern is my LPG water pipes... I followed Martin's (imbers?) LPG water works diagram so i hope it's ok. I seem to recall Ting off the input of the HBV and returning the flow to the lower of the two outputs.

To the owner of this pic... please can i use it?? :D I will take it down if you object. Regards

I guess it depends where your standing wether lhs or rhs ;D
But if you stand at the front of the bonnet......its rhs :y
I dont think id try cleaning a facelift pollen filter......they're charcoal filters.......so look a bit grey to start with.......its to do with the auto 'niff' sensor the facelifts have :y

No your not :y......you would expect the temp to be colder if restricted airflow.......but it was a KF fitter measuring the temp :-X

If the HBV is OK, it could still be the vacuum supply to it that's problematic. :-/
LPG plumbing looks OK. HBV is stll controlling flow to the heater matrix.

Ive had a new HBV recently......and made no difference.......tho i will check the heater pipes going to the matrix like you have to see what i find :y

It'd be interesting. It's possible that mine were hot from having been parked up, but having driven it for 5 or 6 miles on "LO", then pulled up, opened the bonnet and felt the heater hoses, they were all too hot to touch, including the run to the auxiliary pump and back. I would have thought they'd be coolish or cold.
I am losing coolant very slowly too, so I had already bought a HBV with plans to change it when I LPG it. I'll see if that works, and also check the vacuum to the HBV while I'm at it.
Kevin
-
I'll check my vaccum today also. I would have thought that there should be no vaccum when cold and then a vaccum when hot?
I'll report back later...
Ohh the joys of the Omega! I have clutch drag, noisey lifter, water leak at the LPG evaporator to sort this summer, not to mention some rust i need to nuke >:(
-
when you had your ac regassed did they tell you what the pressures where?
-
Nope, i didn't get the printout... They started my car at 5:15 last friday and the automated system took an age, flushing, leak tests etc... the last stage was lubricant i think!
One thing that makes me worry is that the final (or what i thought was the final) stage of the gassing was the lubricant stage. This stage hung for about 15mins and the lubricant was stuck on 0.845gms, whereas they took out 0.950gms. It was as though the system was struggling to inject more that 0.850..? It was at this stage the KF chap started turning knobs and pressing a few buttons, this gave me the impression that he was aborting the process and not letting the computer do it's job.
:o
-
oil first, gas second!!
-
Come to think of it... if it was refrigerant that was stuck at 0.850gms and this should be 0.950 as the aircon warning label under the bonnet says then i think i need to revisit them A-SAP!
-
oil first, gas second!!
Ohhhh shoooot! If this fooks my compressor up, who do you think will cover the cost? ;)
I think i should drop it into KF ASAP...
-
to damage the compressor they would of had to either a, serious overfill it or b, slug the compressor.when they did your car was the engine running?
-
Engine was off and stop knobs on the air-con machine were switched off... thank god!
-
just an update for you all to note...
Called KwikFit call centre and raised a luke warm complaint about the aircon service i had. A few days later an area manager called and was quick to offer a re-gas for free!! :y
Had the car gassed at Worksop last sunday and they took out 450gms and put 950 back in. CC is now cold as ice and gives me the jitters 8-)
-
Dont they say if they cant get it 10% colder you do not pay anyway

Yep. But they normally try it on, charge you and send you packing before you've had a chance to realise it's made FA difference IME. >:(
Having said that, I got a refund off the area manager with no hassle. Might get mine checked out again, actually. Maybe they under-filled that too. New HBV went on with the LPG front end and it didn't help. :-/
Kevin
-
I didn't complain that it wasn't colder, because it was much colder. I complained that the aircon machine failed to complete the job and the operator pressed the stop button and shut it off.
The area manager didn't even quiz me, he just asked where and when i would like it regassed. No messin.
-
erm... Anybody found out where the ac gas went in the first place? Has it been checked for leaks? With funny yellow glasses and a uv light? My pre f lift went 6 years with the same gas. Temp would reach 5 degrees, then one day no ac. pump not turning no gas, hole in condenser... Did you say they put 850 in then took 450 out? 400 missing... ? Or have i had one to many?
Have been told the dryer has silicon chrystals in it, and another source said it only needs changing if the system has been opened to the air... Other wise the chrystals can break down and block the system. What ever the case, consider an air con specialist, have seen a phew moans on here re quick fit up. Opening the ac system/diy not recommended.
-
I'm assuming they vacuumed it out and then the machine failed half way through filling, so nothing leaked, they just failed to fill the system completely.
Kevin
-
nah i don't think it lost any, more like they fluffed it up during it's first visit. Both visits had a positive pressure/leak test so i don't think it's leaking.
Seems ok for now anyway...
-
Had mine re-gassed by KF and they didn't do the job properly. When I first went in the gass leaked out as they didn't put the caps back on, second time I visited them they repaired the fault, as it was leaking, and they still didn't do it properly, still felt as if there was no gas in the system. Then decided to take it to a garage we deliver to and they presurized the system first found no leaks and re-charged the system and it took 950kg's of gas, now its nice and cold bbbbrrrrrrrr.
I don't think KF know how to do the job properly, they just bung it on and hope for the best until they think its full. Waste of time IMHO.
