The TXV is not genuine or OEM. Only available is other parts as dealers don't supply AC parts. We dont have those smaller cans but can buy the required gas in weight , in Kgs. Yes, you are right it cycles on/off in normal use but I didnt feel it in the cabin. Is there a way to see if the compressor ...

Insatlled new RD and TXV (1.5 Ton ?). Vaccd and held for 1 hr. Put 20ml of ND 8 oil and charged till sweating from suction line. The fiugures are; Ext temp - 29 C, humidity 90% (from weather guys) Low side - 28 , High side - 170 PSI RPM - 1600 Interior temp came down to 11 C after a while. This is w...

Thanks. Removed both TXV and RD. The TXV looks clean and not blocked(?). But when I removed the line to RD from condensor there was a big hiss, indicating blocked RD, I guess. Now to buy these two items. What it means by the tonnage on the TXV, (I have seen on ebay TXVs)? The one I removed has no ma...

Hi,
Removed the expansion valve. Here are few pictures and I cant say whether its blocked or not.

Ooops, can't attach, too big.
Anyway, thought of replacing both TXV and the drier. Then vac and see any leaks.

Oops!. sorry guyes, forgot to tell you all a very important observation.

Upto the time the compressor stopped, the expansion valve & the suction line was frosted. That's why I think the shop tech thinks the expansion valve is blocked. Is there a way to check the expansion valve?

sadly, there are no AC recovery equipment with AC repair guys here and it's not mandatory too. When recharging they dont weigh the gas, instead they go by 'sweating suction' line. About 3 years back I did the shaft seal with items purchased from this site sponsor, so dont think it's the seal. Anyway...

Hi, My car, (BMW 525TDS 1997 model year), was not used during last few months due to Covid restrictions. Last week when I started it , noted that air coming through vents are slow & not enough cooling. Compressor engaging and both condensor fans working. Further investigation revealed taht RHS b...

You are head-on.
Removed one of the shims and cooling back to normal.

Thanks.

Yes it's original system came with the car. Can it be the clutch not engaging properly? Before this issue, on & off the belt slipping screeches were heard but not continuously. But cooling was not affected. Now it's not making such noises & the belt is fairly new. The ratio you mention, is i...

Yes, it's an expansion valve system. What could be the reason/s to have high low side / low high side pressures?
