Grand Picasso c4 aircon leak

Hi all I’m hoping you may be able to help. I’ve had my grand Picasso c4 2015 regassed twice in the last 2 years. My local garage can’t find a leak they have put dye in it but can’t find anything. They pressure tested it and it loses 1 bar over 3 hours. Anyone got any ideas

Leaks can be notoriously hard to find and not always in the obvious places.

You may have a leak in or near the evaporator box inside the dash. There are probes with UV lights or 'sniffers' that can be used to better detect any leaks from these areas.

Having said that, it took the main dealer 4 attempts on 4 separate visits after recharging to...

On your passenger compartment fuse box, there is a SHUNT fuse, used when the vehicle will parked up and not used for longer periods - it shuts off some of the electrical system to conserve battery power. Check your manual for the position settings, but is should be shunted to CUSTOMER position.

Air con always on (xantia year 2000)

My problem is that the compressor engages with air con switch off. This causes fans to operate. Switching on the system lights the indicator in the switch. Unplugging the compressor disengages it. I need a wiring diagram of the system and location of the various relays. Any suggestions would be appreciated.

Isn't that what air con does. Remove water from the air and dry it.. Hence its use as a demister.. The water is what has been removed from the air and is deposited from an outlet pipe..

No you don't have Adblue - that wasn't available on PSA vehicles until 2013.

You do have a Diesel particulate filter though which requires an additive, which is not the same as Adblue.

Adblue is used in vehicles with SCR (Selective Catalytic Reduction) technology. SCR is used upstream of the DPF (Diesel Particulate Filter) to eliminate 90% the...

C3 1.6vti Exclusive Auto, Climate control issue.

by xero1 » 22 Apr 2019, 17:52

First post

Hello everyone. Just registered as i have been trying to get to the bottom of an issue with my wife's 2011 Citroën C3 1.6 vti 120 Exclusive Auto. The car has electronic climate control and works intermittently, when it's very warm the compressor doesn't engage and the engine cooling fan doesn't run.
I've had the AC serviced and the gas is fully...

Last post

Be aware that the A/C system will be shut down if any fault is detected in the engine cooling system, such as a faulty fan or speed controller, or even the thermostat heater (if fitted). You really need to get all of the fault codes read for the A/C system and the engine ECU.

X7 Compressor refrigerant leak

by EDC5 » 22 Apr 2019, 16:32

First post

Since a refrigerant recharge last summer my air con had all but lost all effectiveness and the system hissed loudly inside the cabin, the usual sign of low refrigerant charge.

When I checked the pressures, I found the low side pulling down to 0 psi and the high side was really low for a 134a system.

The system was recharged once again and this...

Last post

Yeah, when I took mine out it pretty much disintegrated in my hands. A condenser is probably easier and cheaper than a compressor at least, if it is that.

Hi, I have a AX here and want to fit an airco system in.

What is all required?

6457 Y4 kit?

So Far I know:

Airco pump w/ bracket
condensor
pressure regulator
fan switch 3 pin
seperate box for a/c
tubing
radiator interior
and a computer that can run an a/c?

Last post

The highest output I can see from all the AX alternators is a 90 Amp Alternator in various brands. They go from 50 amp to 90 amp which includes models with air conditioning fitted. So as long as you don't have a load of amplifiers and a recording studio in the back you should be ok.

No I dont have a lot of audio in the car just basic two...

Can’t turn off the air conditioning on my Citroen C5 2010

Hello everyone i will be glad if someone can help me with this. I replaced the polen filter and since then i can’t turn off the fan on air con. Just blowing on max speed all the time. Trying to turn off or adjust from control panel not doing anything. Any ideas!

The blower motor is probably faulty then. They do fail and this is one of the symptoms.
How does that work Marc? TBH I can't see how the motor can be faulty and give this symptom.

A motor can only go at the speed dictated by the control unit and this is supposedly set by the control panel. Into that mix you have to add the BSI and, if there's a...

Hello again, went to the local citroen garage today for a regas....and he found a leak. The first suspician he had was due to evacuation taking too long.

Citroen C5 A/C

First post

I have just bought a 2006 Citroen C5 1.6HDi 16v VTR estate.

I don't have an owners handbook and am trying to figure out how to get the A/C working. I can get air coming out, but even with (what I assume to be) the temp at Min. the air coming out is always warmer than outside air. I am not sure whether this is because I am not using it correctly...

Last post

Make sure to go to a proper a/c capable garage. Places like Halfords just add gas to the a/c system. Specialists will evacuate and separate the original contents of the a/c system, put a vacuum test (to test for any leaks) on for twenty minutes or so, then add in the oil, U/V dye and refrigerant. The process should typically take an hour or so....

If your system wants a recharge - don't wait!

by Zelandeth » 22 Apr 2018, 17:24

First post

You may or may not be aware that there's currently a drive underway to phase out the use of R134a which most relatively recent air conditioning systems use.

The effect this has had is that it's vastly pushed the wholesale prices for the refrigerant up. This is only going to get worse.

The local garage I've used for stuff like this currently...

Had a chat with my garage mate today about the air-con gas pricing, he tells me that last year he was paying £60 a bottle for the stuff, this year same stuff £340 a bottle.

C5 X7 True 'Climate Control' ?

First post

Just a quick question: Whilst browsing the menus of Diagbox under the climate control live parameters there only appears to be temperature sensors in the ducts supplying air to the passenger compartment. I don't believe the C5 has actual temperature sensors in the passenger cabin like other cars with CC do.

I really like how the fan speed is...

Thanks for the reply, I'll fit the unit and leave the connection loose until I get to the refill station.

I should have said the garage didn't want to get and fit a unit due to the cost - it was almost 700€ over here. The owner didn't want me to feel as though he was ripping me off on charges, the reason why he said if I get the unit he would fit...

I think that the presence of a logged cooling fault has disabled the A/C.

Not overly difficult but you'll more than likely need a special tool to separate the spring lock connector where the metal section connects onto the metal pipe by the inner wing, they aren't expensive or difficult to find, a quick google will reveal all.

Have removed damaged condensor on wife's C3 and am about to order replacement.

The double O ring seals on the two pipes seem to be OK but should I use some sort of lubricant or sealant when I fit the new condensor.

If so, then what should I use?

My neighbour here (in France) has a Renault Laguna V6. He came to me for help the source of a noise that had just started. To me it sounded like a timing chain, if, that is, it has a chain and not a belt. But then Chris, the (english) neighbour, switched on the aircon and the noise got a lot worse. I didn't ask whether the aircon actually worked,...

My first guess is the compressor clutch or its freewheel bearing.

Or maybe a delaminating dual-mass crankshaft pulley.
