Drivers side blowing cold - All In Cover

[mbenne]

I'm really disappointed in VW jumping to the conclusion that the heat exchanger is immediately the problem (the dearest item)when the errors clearly show that the flap position sensor is stuck/grounded as mentioned in my previous post. The small plastic actuator is really not fit for purpose and VW don't even list it as a spare part, you need to by the whole motor unit with the actuator on it. I had to buy a replacement piece on the internet and plug it in to the motor.
This is basically a mechanical piece failing and then producing an electrical fault when the potentiometer in the motor revolves too far.
Cannot understand why they won't just take a torch and look up under the foot well with the small panel removed and visually check the flap linkage! They should know where it is.
Might be worth another chat and ask to speak to a technician? Failing that another dealer if they don't seem to be playing ball, they're not exactly going out of their way to help you much.

Visual inspection completed as per your advice.

It's definitely a broken actuator arm and redoing VCDS confirmed same fault as the VW mechanic.

I'll be going back to them to confirm that the fault is covered under warranty. It was a shame we didn't have a spare to hand as it would have been fixed now. But I suppose that's why I took out the extended warranty.

Thanks for all your help.

UPDATE - thought you might appreciate knowing the final outcome.

The heater problem fix was deferred until this week as it coincided with the MOT and saved two visits to the dealer.

All went well, MOT pass - no faults and heater problem finally diagnosed and fixed under All In One extended warranty.

Not sure what the issue was exactly, as everything indicated that it was a broken actuator arm but the engineer's comment reads:

CONFIRMED CUSTOMER REPORT OF AIR CON SYSTEM FAULT, ON INSPECTION FOUND HEATER BOX TO HAVE INTERNAL DEFECT. REMOVED AND REPLACED HEATER BOX WITH NEW. TEST CONFIRMS FAULT RECTIFIED.

No idea how much this would have cost as the invoice shows £0 for labour and components, but based on labour costs alone (previously quoted circa £900) for dashboard removal the 2yr All In One premium has paid for itself.

Looking forward to another stress free year of motoring and camping!

See update below.
My son, who is an aircraft engineer, originally pointed out the A/C issue on a recent trip to France. He was appalled at the dealers response, particularly as the outcome of the engineers VSDC test was never recorded on the inspection outcome.

Ii they'd pointed out the fault then explained the cost with an indication that it would probably be covered under warranty I'd have been a lot happier. As it is, I feel that they are being cagey!

Can't your son fix it or you?
