Hi guys,

 

Am driving a 2010 Skoda octavia VRS Mk2 FL. Recently felt the aircon is cold and send in to a mechanic for checks. was told that the aircon compressor is weak and was quoted a price to replace it with a new one. I searched online and found compatible aircon compressor at a very low price from UK. inclusive of shipping, it is still much cheaper than buying an OE from my place. Some questions i have:

 

 - Any one can point to any resources that can guide me to identify the OE number of my existing Aircon compressor?

 - What is the software/manual/website for one to check OE part numbers with the chassis number?

 

I tried searching the forum but the search function wasn't exactly powerful enough.

 

hope to get some guidance here.

 

thanks folks.

 

cheers

 

Paul

 

You need a mirror on a stick to look at the underside of the aircon compressor from front of car with bonnet up.  There were several in use I believe, Denso, Zyxel.

 

My 2011 vRS uses 1k0 820 808a, denso I think. There is a degree of cross compatibility and equivalent replacements from Nissens, Hella and others work I believe.

 

I would strongly suggest before replacing though, to take to an airon specialist in singapore (there msut be a few of them?!),  and get the system checked for leaks, check sensors, valves and gas refilled and confirm that the compressor is actually at fault.

Hi there,

 

thanks for the reply. I have actually sent the vehicle to 2 x aircon specialist here in SG and was told that the compressor is getting weak. No leaks, sensors working fine apparently.

 

to use the mirror on a stick, i probably need to jack up the car? based on your experience, will denso be the most reliable replacment?

 

cheers

You can do it with a small inspection mirror from the front of engine bay with bonnet up. No need to get under car.

 

Or improvise, a make up mirror attached to a wire coat hanger will also work.

 

I'm still on my original which is a Denso. I don't have experience of the others but AFAIK if you stick with a quality name mfr as listed above, they are all decent. I think I recall there was a problem with one design of zyxel which was less reliable but I can't remember details.

Well, I've never heard of this with regard to an automotive air conditioning compressor. Ask one of these specialists how it is getting weak, and ask for specifics like flow rate, pressure, and what they would consider to be "normal for the system".

They will not be seeing the high side pressure go up to what they are expecting, many reasons and a weak compressor being the least likely.

 

Undercharged, they have not corrected for temperature, the Climatronic may not be giving a full modulated voltage to the control valve for whatever reason (the most likely IMO) unless they are monitoring that through VCDS or have hot wired it with a jumper box they will never know if the compressor is being asked to give full output, its not an on/off like a compressor with a clutch, its a variable output, several mechanics have thought mine was faulty because it was not declutching when it could never do so, normal operation at anything less than 100% duty cycle will look like a weak compressor in their eyes.

This is the one I got for my 2010 Mk2 FL VRS CR. Fitted and works perfectly.

wow guys,

 

thanks alot for all the inputs here. i am bringing the car to another specialist armed with all the steps and questions mentioned here.

 

really appreciate all the feedback here.

 

thanks alot! will update this thread of my findings.

 

cheers

 

Guys, try as i might but i can't see any numbers on the compressor with that small mirror!

 

I googled the below part from a UK website. would this work on my car or i need to match an exact one?
