Hi

 

I have a 2006 1.2 HTP, for just over two years, well looked after, never let me down, but from the start I have had the usual no heater issue.

 

Now it is starting to go colder again, I am considering selling it, but only because of the heater issue.

 

I have posted about the issue on here before and tried everything other than replacing the flap motor, something I am not really confident enough to do but may now have a try or may sell, not sure which yet.

 

I did a scan with VCDS yesterday and it reported the following:

 

Address 08: Auto HVAC       Labels: 6Q0-820-045.LBL

 

  Controller: 6Y0 820 045    Component: Klimaanlage        X0840   VCID: F297D9CBADB7 2 Faults Found: 65535 -  Internal Control Module Memory Error    

 

 00-00 -   01271 -  Positioning Motor for Temperature Flap (V68)        41-10 -  Blocked or No Voltage - Intermittent

 

I've not seen the internal control module error before but the Flap Motor I think is the main issue.

 

I know nobody can make a choice for me, but is changing the flap motor that difficult, I have read on here and some say it was fiddly but  can be done, and others have said it is difficult . As long as I have a good idea of what I am doing and take my time, I normally can get things done.

 

Has anybody on here currently done this and if so, how difficult was it?

 

I also know,being realistic, to get a garage to do it for me is now not going to be worth paying for due to the value of the car.

 

Never had issues like this on any of my other cars and is frustrating as if the heater worked the car would be perfect, and to be honest, as much as I like the car, it would probably put me off Skoda,VW or Seat in the future.

 

Many thanks to anybody that replies.

Whereabouts in the UK are you Martin?

Hi Wino

 

I'm in not so sunny Blackpool.

Oh. Was going to offer to help you with it if you were nearby.

I do have a load of photos of how it all is arranged in there; taken on a system outside of the car.

Can post some of those if you like.

Not done the job in-situ though, so not sure how much the awkwardness of access affects the difficulty. A fair bit, I should think. You sound like you could do it, to be honest.

Thanks for the offer Wino, but I am a bit far away.

 

If you have some pictures that would be a great help, at least I know what I am looking at replacing and how it fits in.

 

I also need to price up the part yet but thought I would see if I could do it first.

 

Martin

I'll stick some photos up later when I've done all my chores.

Thanks Wino, much appreciated, might go and price up the part now and prepare myself :-)

Just been reading some more, and it has been mentioned that there have been case where people have changed the flap motor and it has not solved the issue. Then people have mentioned changing dashboard temp sensor behind the vent between the dials, I wonder if that would be an easier place for me to start, I wonder if that is the fist error and could be causing issues.

 

When I use VCDS I can hear the flaps moving and it seems to run without any problems.

 

If I were to change the temp sensor, does that mean I have to change the full heater control unit on the dash, I have seen them for sale on Ebay.

 

Just another thought. 

As you have VCDS, can you not use its VAG SCOPE and see what happens when you change the temperature, I'm guessing that you have tried BASIC SETTINGS ?  Normally - a word with very flexible meanings, the temperature flap motor is one of the easier ones to change - well when compared with some recirculate flap motors. I replaced it on my 2000 Passat, as usual, it helps if you have "lady" hands and are willing to be inventive/creative with which tools you use to remove the screws/bolts.  My problem was the opposite from yours, the car was getting far too hot, so hot that we had to stop to cool off once, so that is what gave me the incentive to finally fit the flap motor that I had bought a year or so earlier.

No, I've not tried VAG scope, will have a look at that later on.

 

I would love some proper heat in mine, I can feel very slightly warm air but as soon as it gets really cold outside, you know it is not good enough.

 

I got a heated seat cover for last you to try and make me feel a little warmer, as I said, in all the cars I have ever owned, if the heater was not hot enough, bleed or burp rhe system problem solved, not with this though.

I'd love you to see this solved, pity for a good car failed by one small fault to be rid of !

This is what these forums are for - I don't have any experience of ths myself but good luck !

 

Just to add +1 I don't think the flap is relevant. Its a common fault.

It's on mine too ( not sure what it really means, but I have full range of temp and the heater works more or less perfectly so not worth the hassle).

Its annoying to know there is some kind of fault, but when it doesn't really seem to cause any kind of issue.

 

Just fix the heating issue. I'm +1 for this being an electrical issue with some component like the stat that controls the temperature. Could it just be that simple ?

Thanks vRSAnt,

 

Interesting to hear you say it is on yours but you don;t have the issue, when I check with VCDS I can hear the flaps turning, the air con works fine and everything on the control panel works, it was interesting to read about the temperature control sensor, seems it is behind the small grill on the heating controls, it would be interesting to see if I could do something with that.

 

I have even had the radiator flushed last year to see if they helped, but nothing.

 

I really don't want to sell the car, only a small basic car but it does what I need it to very well. 

 

Maybe I should buy a hat and gloves, could be cheaper.

 

Martin

Cigarette lighter socket OK ?

 

Pro temp, get yourself one of those hand held electric screen defroster. Takes the chill off the air. Dual purpose, with winter coming on.

 

And at £15 it saves you the cost of a proper repair and a year's worth of buggering around from those who claim to know but either don't or can't be arsed to do the job - assuming anybody, including MDs, know how to do it (But that won't stop 'em charging @60 an hour).

 

Or a 1000Kw inverter and a small fan heater to stick in the passenger footwell - only operate when engine running !

You can watch the live temperatures given by the various sensors in the HVAC module measuring blocks. Have a look if they all seem plausible. TBH, given that it has moving parts and the same cheap plastic potentiometer as the recirculation flap motor, I'd be surprised if the V68 wasn't your problem.

Hi Nick

 

Cigarette lighter is fine and I had thought of getting a plug in heater, I know it would not be that good but better than nothing.

 

I have not been able to find one yet without it having bad reviews, that is another option I suppose.

 

Thanks again Wino, think I will book myself a day off and get to the bottom of this, one way or another.

 

Martin

Right, I have checked the temperature module on the heating control's.They were dusty, so I cleaned them, but no difference. So I think I can rule that out.

I think I will price up a V68 and see if I can replace it, looks like I may have to remove the existing one to get the part number, so I suppose I can practice at the same time.

Am I thinking of a different flap problem

 

Really sorry, there is a common flap problem, but I found my logs and it seems to be a different problem and may explain why I don't have issues anything like yours.

 

I think this is the recirc flap sorry. Sorry for any confusion.

No worries, still very annoying though, looking at different flap motors is very boring ????????

Lol. Yes indeed. Bear with it though, it will be worth it, this is more than just a perk to have, its really essentual equipment really isn't it so well worth your effort.

I reckon there might by now be more Mk1 Fabias with the recirculation flap faults than without.

I agree Wino, just hope there are plenty of decent second hand ones for sale.

I think that will be the better than a new one from the main dealer given the value of the car.

Don't suppose anybody has a part number for a 2006 Fanta.

The recirc motor is a (much?) more common failure than the heater flap one, and that's what I was talking about in post 20.

 

Part numbers for the heater flap motor are confusing me a little at the moment.  After 2004, the motor module isn't listed separately from the little carrier bracket it sits in, instead you get those two parts listed as a single part number 6Q0819453E. That's what you see for 2005, 6, and 7 cars/catalogue pages e.g.  item 31 here.

 

In the 2004 catalogue,  the motor module is listed separately -  item 27 - 6Q0907511, but says only up 'til the end of 2003. Not sure if that's cos they changed it in some way after that, or just decided to sell it with another bit, at a higher price?  Edit: scrolling down a bit on that page, two different part numbers for item 31 suggests something 'real' changed, I think.

 

I personally would only fit a secondhand one if I'd seen a VCDS scan of the car it had come out of, not showing any faults with it, otherwise it seems a bit of a gamble.  If you do gamble, try to get one from a car that's as late, and low mileage as possible to maximise your chances of one that's got some life left in it.

 

Got some photos uploading to the cloud now, but I think judging by what 6Q0819453E looks like in google images, what I've disassembled is slightly different in the mounting bracket.

 

I seem to remember there's a how-to for replacing the heater flap motor on a Polo on some Polo forum, other than dashboard trim panels, probably very much the same.

 

This image from googling 6q0819453e might give enough info to go via manufacturer's (Behr) part number to the motor module alone?

This is what I took off, a housing with a space for another module not fitted to the car it came off. Motor module itself Is the 6q0907511 part number and made by Bosch. So I have a feeling my disassembly photos may not be completely relevant, will pick out a few representative ones anyway later.

 

This shot shows how easily the motor module fits/unfits from the carrier bit. But you have to take the carrier bit off first unfortunately. Your carrier bit will not have the spare location, I think.

 

It's right alongside the pollen filter housing, between it and the main body of the heater box  (orientation is confusing in this shot, the pollen filter slot is facing upwards, on the right!):
