hello,,   Car aircon is leaking and I do not want to let Somchai work the way he knows nothing. I want the job done the correct way and I want that they use a gaz leak sniffer and / or

So all garages know how to detect and air condition leak ?  

Yes Thomson is sure as hell busy. But if you contact the owner Eddie on LINE (fantastic guy btw), he will let you know a date in which you can bring the car. And most likely it will be done in the day

Another thread was closed so I post here again what was explained and requested

Car AC aircon air conditioning gas refill shops, how do they know that they put enough ? I think they just don't know ! But maybe you know ?

 

Cheers,

My car AC has a leak and until I fix it I have o refill few times a year.

What is funny is that the only real way to know how much gas there is in the system, is to empty it (flush), and then put the amount required.

When they just refill I wonder how they know what is the total gas in the system.

For example my car should have 630g, but what they see when they refill is only low and high pressure, not the total gas in the car. Please check the pictures before and after refill, do you think that they refilled enough ? Or it's clearly impossible to know ?

And what if they put too much ?

 

I am wondering if any place is actually able to totally empty/flush the gas and refill it with required amount ?

But how can they know that they inject 630g even when they gauge does not show any quantity ?

Please tell me what I do not understand ?

 

Greetings !

I wish that people do not comment to tell me to fix the leak blablabla... as you can guess I already know it !

The title of this post is:

Car AC aircon air conditioning gas refill shops, how do they know that they put enough ? I think they just don't know ! But maybe you know ?

And this is the only thing that I ask you. If you don't know, please just do not reply.

 

 

 

 

 

 

 

 

The only way to know how much gas and how much oil is in the system is to empty both and refill gas + oil. Anything else is only estimation.

You won't find any standard shop that has an idea about what I just said. They all live just as 30 years ago before Internet.

The irony is that today I just happen to walk past a shop that is specialized in refurbishing wishbone and they can replace the ball-joint for 700 baht a piece.

Well, live and learn!

Somchai 1 - Thomson 0 or actually minus 24,180 points to Thomson, since that was the price I paid for a fix that did absolut nothing. 

 

Somchai saved the day.

Turns out that BMW in their infinite wisdom install cabin heater on their cars in Thailand. The hot water from the engine is controlled by two valves (left/right cabin air control). The valves are most likely working but over time the internal rubber seals starts leaking, sending hot water to the cabin, constantly fighting the AC.

It makes totally sense, as my floor heating slowly was getting worse over the past 5 years and the driver's side was far worse than the passenger side.

2 hose clamps and a small wooden plug and the heating loop has been permanently disabled. 

Finally, I can take a drive without getting my shin roasted. At one point I was getting 65°C air out of the floor vent.

Now I just have to deal with penguin droppings!

What separates a true mechanic from a parts swapper.

Did you go back to Thomsons - tell them and show them - would of loved to see the look on their face ! If not you should.

Weirdly enough it was a combination of farang methodology analysis and Somchai BMW knowledge. 

I have been fighting this problem for 5+ years and have been to 6-7 different shops.  They ALL pull out the 3 hose pressure gauge kit and offer their faulty opinion. 

This time, when I explained the hot floor air, the penny dropped.

No point in going back to Thomson.  They were a bit arrogant and kind of laughed it off when I suggested an alternative to their "expert" opinion. 

I took their word for it and paid the price. Lesson learned.

Just got the bill from Somchai, 600 baht!

For that he also fixed:

1. Windscreen washer, it was just gunk in the filter,

2. Right-rear electric window. It was stuck 

3. Dropped the exhaust pipe and changed a rubber seal on the drive shaft. 1+ hour job,

4. Brilliant fix of the aircon,

5. Did a test drive around the block with me.

 

In total he spend about 3 hours on the car.

Long live Somchai.

You mean, the way Thomson has been plugged in several threads lately, is not justified?

Thomson being good was the only reason I felt confident in picking this car up:

This thread depresses me, though I'm glad a cheap solution was found. 

For 400k this is actually a nice car.

Nothing's good about BMW... Take a look at your own car, the inlet manifold is made of freaking PLASTIC! 

 

Not even a Toyota Vios uses plastic for the Inlet Manifold! 

 

BMW expensive as premium, yet gives you plastic all around the engine, which sooner or later causes oil leaks, compression leaks...
