    I celebrated too quickly. I should've known that the car wasn't losing cooling slowly.

    Car is not cooling again. At least I know there is dye in so will check when I get home for leaks.

    Let's hope I find the leak in an easy place!

    This is the reason why I don't take my cars to dealers!

    When they initially had the car to diagnose the failing engine they dropped this screw down into the radiator area where it wedged between a cross brace and the condensor.

    I know it wasn't me as I didn't work in that area, and I kept track of every nut, screw and bolt!

    Over time it chaffed through and now I have a leak on the condensor!

    Bliksems!

    Good thing you found it now. Very similar to what happened to mine after the panelbeaters. Incorrectly routed pipe chaffed through the condensor. Hope the condensor can be repaired.

    I am hoping the system can be evacuated, the chaffed area soldered/brazed in situ and then vacuum pulled and re-gassed.

    My condensor had to come out for the repair. Whole job took one day. They charged me R 2 200 in total.

    condenser is usually a consumable... maybe if someone is lus to weld it, luckily it is not a essential part of the engine so you can give it a try

    I have seen a few radiator repairs done by professionals. I'm confident (and hopeful) this can be done in situ.

    So R200 for a topup of gas and UV dye. Let it run for a while and check for leaks.

    No leaks and it cools better than ever. All in all a big relief!

    Kevman is correct, a system don't loose gas, but on car aircon system it does, normally via the compressor pulley, especially when it is not in use for a while (Perhaps the time you changed the engine on the treg) the seal on the pulley of the compressor become dry and loose gas ,when you use it again it lubricates and the leak disappear.

    Maruis. Daar is alu welding rots op die mark wat jy met n porta pack dan weld teen n lae temp. Kyk by Afrox, weet nie wat dit kos nie. Ek het al n paar so reg gemaak. Dit is nie die maklikste job nie. As jou vlam te warm is gaan jy jou coil stukkend brand in n oog wink. So wees gewaarsku as jy die roete gaan in DIY. As die lek reg gemaak is doen u druk toets. As daar geen lek is nie, trek al die lug uit met 'n vac pump. Kry vir jou 'n skaar en skaal die regte hoeveelheid gas in. Neem aan dit is 'n R134A system.

    Ek het daai rods op die internet gesien maar ek het niks experience op dit nie en wil ook nie school fees betaal nie.

    Ek het 'n quote van 'n ou wat al 'n paar van my karre (ek het nog nooit 'n kar gehad wat nie AC issues gee nie ) by hom gehad.

    Hy het my R1500 gekwoteer om condensor uit te haal, tube af the block, reassemble en te gas. Klink na 'n bargain in my ore maar op die stadium moet dit maar wag. Ek's *** broke!

    this car handles bloody good! It doesn't look heavy on the video but trust me it was close.

    The touareg handled it with ease. No drama, no tyre squeal, and I don't recall seeing the ESP light blink.

    I am now in a predicament.... sort of

    AC was working 100% and then stopped working. Take it in for a check which shows low gas. Topup and bob's my uncle till the next day.

    Search with UV light and found the leak on the condensor (see previous posts)

    Send car in.

    The take the condensor out, fix it, put it back, pressure test checks out 100%. Evacuate and gas. No cold air.

    He changes the solenoid valve on the pump (no clutch here - a solenoid valve controlled by the ecu allows or restricts gas flow - the pump has an inherent oil system like a car's sump - separate from the refrigerant system) and tells me the pump looks clean with no signs of ageing wear.

    Still no cold air.

    So I shoot over, clear the codes which was obviously present due to the repair.

    Still no cold air

    I recode it via vagcom to ignore the refrigerant sensor (even though errors didn't come back after clearing)

    Still no cold air.

    No the guy tells me he reckons the pump failed. So I jump on my horse and ask him how the hell he reckons the pump failed if it was working before and when he found no debris of any sort in the pump to suggest a failed pump)

    Pressure is good
    Solenoid valve gets voltage and clicks
    compressor rubber coupling is good
    measuring blocks on vagcom shows ecu is engaging the AC pump
    vagcom doesn't show any returning errors

    Now I'm stumped as well as the AC guy so they are getting a VW/Audi electrical boffin out there tomorrow.

    Any ideas?

    I know it's very sensitive to the quantity of refrigerant, - needs to be filled by weight to exact spec.. Also perhaps condenser now has a blockage/restriction?

    I have just studied elsawin and I suspect they didnt turn the pump by hand a few times after filling and when they started the car the excess oil in the pump caused the overload protection device (it sits between the freewheel and the pump - looks like a jaffle maker) to sheer due to the pump not being able to compress the oil like a hydrolocked engine ( the R5 pump is always turning, there is no clutch. Only a solenoid valve that controls refrigerant flow) the pump has 50-80ml of oil in the pump sump to prevent dry running in the case of refrigerant loss.

    Thank goodness for this overload device otherwise the pump or the coupling would be toast! I hope you can get spares for it.
