ATC issues

ATC - (Set L19c/R19c in Auto default)

Has always an issue since birth and had been behaving fairly well until the recent hot spell but now sometimes decides to only blow warm air - or if ECO pressed hot air!?

If this occurs all you can do is increase the temperature the passenger side to say 26c and shut the vents - then at least driver side blows cool but certainly not chilled. However that leaves the noisy dash and under bonnet fans fighting out both the hot and chilled air!

ATC fault code diagnostics normally flash ?00? (no fault) but sometimes alternate ?21? & ?22? - sun light sensors L & R - no solar heating correction?

Sounds like the heater valve needs replacing!

Only 300 miles until it's next service so I'll get them to investigate - thanks!

Tim now you are green have a good read before instructing a garage. :) The new valve we have may sort the problem out.

Welcome to greeness. :D

Another Herts member....welcome along

Mine also does a strange thing one minute it's cold the next warm.. Not sure, but may be a sticky or leaking heater valve (internal leak not external)

Also how/where do I upload photos of my pride & joy?!?

ps I'm just up the road from Hemel. I'll keep an eye out for you (once I know what your car looks like lol)

pps the sunlight sensor code you mention in your op (21 & 22 - sun light sensors L & R - no solar heating) simply means that there is no light reaching the sensor on top centre of the dash under the screen - usually because it is dark or the test is being run inside a garage

I'll hopefully be able to give some news on the next batch of valves in a week or two

Keep an eye on the Shop section of the forum

Feel free to order anything else while you're waiting :D:D

Thanks all - & pictures just posted on the web!

Sounds from the forum as if it would make sense to purchase the following in one hit;

Uprated heater Hose (RHD)

Uprated heater valve

F&R enamel badge set (ZT)


Please confirm!

Heheheh is the corner shop man going to say no? :D:D

I'll come back asap on valve availability and PM you the details
