Finally got the compressor replaced using Trust Skoda Redditch. Anyone wondering - its a £1000 out of warranty repair, if you don't get Skoda UK to part contribute, i.e. you have no Service History. Excellent service from Trust Skoda Redditch, a big thank you to Chris on Service and Skoda UK. Can't say too much regarding Snows Group, Plymouth, 'ongoing' but it ain't good.

I think you just destroyed the marketing of the 2014 Yeti, not sure Skoda would like them been coined 'Blind Yetis', but a feeling it might just stick. (on here anyhow).

Thanks Steve, shame its not exactly the same compressor. Also took the car to an Air Con Specialist (only does AC) in Redditch, who described the fault straight away on seeing a printout of the image. Very helpful guy, has been fault finding AC for 15 years. On asking whether other parts would need to be replaced, said 80% of the time, its a straight compressor swap, but a can of worms if there is debris in the circuit. But very common fault. Realised not everyone can see images without logging in, so here it is again:

This is my understanding of it.. The T30 torx bolt holds the pulley in place on the tapered shaft of the compressor, but the T30 torx bolt is not spinning with the Pulley wheel (remains motionless when the Pulley is in motion). You'd think it was a case of tightening it up, but its possible its caused damage to the tapered shaft is my understanding, due to the pulley slipping. It would be helpful is someone can upload a picture showing a correctly working compressor (screw intact). The system is also correctly pressured (no leak), with the engine off, which also makes you think the internals of the compressor are intact, just not rotating. Difficult to know until its removed/replaced.

Yep, thanks. Its more the time it takes to work out what is actually wrong (and thinking - if indeed anything was wrong - it was). The reason for the posting images to show others. The Standard Used Car Warranty issued by Snows Group doesn't cover AC, but believe/certain fault was on car when bought (picked up 4 weeks ago), spotted this difficult fault 2 weeks ago, has taken time to get booked in, diagnosed properly (that's not as easy as it sounds, with low ambient temperatures), so that I can make a complaint via the SOGA, (Sale of Goods Act). OFT Used Car Dealer Guidelines state the onus is on the dealer to prove the fault wasn't present, rather than me to prove it was, and given its less than a month, hopefully there will be a good result on this. Luckily I noticed early on. Having visuals of the compressor fault, will hopefully make it easier for someone to spot this fault, either on pickup or test drive. According to other forums, its seems that this fault doesn't normally cause swarf/damage to the internals of the compressor itself, so it may be possible to just replace the compressor, without replacing the dissicator / condenser (a single part on most Yetis) at the same time. Haven't found Skoda that helpful either, as soon as I mentioned it might be under warranty, they said I should just run it a while, might sort it self out (this was before the protruding bolt was spotted on the compressor), in other words - delay, till its out of warranty. The car has a full service history, with VW Group.

Have recently purchased my first Skoda Yeti, a 2010 Elegance 2.0D 140bhp 4x4, second hand from Snows Group. After a couple of weeks I realised there was an AC fault. The AC fault was difficult to diagnose because it appeared be operating within its range via the Digital Display 18-26 degree Auto Setting, on startup, but several minutes later - on turning off AC, there was no decernible difference between having AC on, and AC off, of the circulating air due to low ambient temperatures in April. It appears Snows Group sold the car with the fault on the car at purchase. With further investigation, getting it booked in for a diagnostic check/possible regas, with Skoda - the compressor, has been diagnosed as faulty, with a protruding torx T30 screw from the Denso Compressor. I've uploaded two pictures so that others can check for this common fault. The Pulley rotates but the torx T30 screw (central thread) doesn't. If you are thinking of buying a Skoda Yeti, worth taking a torch with you, and a Multimeter with a temperature probe, and checking temperatures from vents (are lower than ambient temperatures, you need to test it after a good run too), so you don't get caught out by a Dealer selling you a car with a faulty compressor. It seems a car with faulty AC is a good reason to trade in/upgrade to the new model, and a slipping pulley on the tapered shaft of the compressor, is a difficult fault to spot, unless you visually look for the protruding screw (see photos) Its not that obvious because my system, the refrigerant was still correctly pressured (no leaks) with the engine off, so first thing when you start the car - there is refrigerant in the Evaporator, initially the air appeared cooler than the ambient air, until this gas in the evaporator is warmed up, and fails to be recirculated/sucked by the compressor, at which point the air being vented is warmer/no different, whether the air con switch is on or off. Any other good tips for spotting Air Conditioning faults, would be helpful. i.e Does the condenser fan spin continually or thermostatically controlled on a working AC? Mine seems to only kick in at 95 degrees oil temp, with a faulty AC.
