Air Conditioners: Coolest Idea Ever
On an episoed of WD you did the a/c recharge yourself as you said you had been on a course and got the required certification. So why call in someone else? Did Discovery snatch your tools?
Watching with interest as my 2009 has a similar problem. Have you checked the radiator fan? This needs to run when the AC is on. You can activate it via VCDS
I did mine and it only has low speed not high. The fan is controlled by a module bolted to the chassis leg. I believe this module also controls the AC. Good luck mate👍
Reminds me when my temp sensor decided to fail when it was several below zero one morning! As I drove the car thought the outside temperature was increasing dramatically, got up to around 40C I think, but played absolute havoc with the climate control. I could manually switch off the A/C, but it was a moot point when the air temp is around -5, and any temperature set on the climate control was below the sensor readout, so it automatically put the fans on full, unless I forced it into ‘HI’, which triggers it to provide max heat at max fan speed, which is nice for a few minutes, but 7kw of heat output soon gets very hot! Whenever I changed the temp it would default to auto and put the fan speed to max, so it was a matter of flicking between ‘Hi’ and the highest temp, but each time I did so having to reduce the fan speed to lowest (so as to not get too hot or cold), there are 10 fan speeds and only a push button to go up and down.
And at the same time, the door handle sensor decided to play up, meaning the window (which drops an inch when the door handle is pulled) kept opening and closing an inch whilst driving down the motorway!
what diagnostic system do you use?
First thing to check. Is the clutch engaging? 😉
You should check if the ac fan works, without that one the AC won’t start
Hiya Edd
Good grief that air con equipment looks well used and in need of a clean.
that tiny oscilloscope is the mvp, so cool!!
good bit of decent flux should have let you solder without making the workshop smell like a chippy🤣🤣🤣🤣
Hi Edward !
Hi Edd, I had an n5 injector fault on my t5 2.5t 174. After 2 garages, new injectors, new injector cable and a lot of time. On the way home from the last garage it died again, after a few minutes of trying it fired up. So back to garage and explain again it seems like it’s running out of fuel. Turns out fuel sender was way down on pressure, so just a point of interest I asked. Which injector is first on the fuel rail, the look of realisation came over his face. As he says number 5, my wallet cried a little.
It is such a fine thing that super qualified people like Edd, Paul and John are around. Hats off for the practical people.
👏🏻👏🏻👏🏻
As always top work Edd and Paul, it’s like wheeler dealers but with no sh1t🤷♂️😉😂
Don’t get me wrong still like watching wheeler dealers with Mike and now Elvis, Christ what does he do to the techs👀😳🤯🤷♂️🤣🤣
