Got a 15 wagon dsg. Simple s trim.

I get basically no heat for until about 5 miles of 60mph driving.

I found this in the engine ecm, hvac ecm and the code is from the hvac module. ..

Without removing the kick panel to confirm if i really do have heavy wires going to a heater I'm not sure what I have installed on this vehicle anymore...


There's another option yet for park heater.
*** is that?

I tried to enable the engine module option, and it complained rpm too high. So I killed engine and tried again, and it just says rejected, out of range.

Ideas?

Got cabin heat selected and applied. Security code was needed. Instant fault code though.

Seems it's not related to the aux heater, that's factory enabled in hvac module but refuses to accept any activation tests


Ideas?

I'll let the system cool down and try and catch it with vcds right away.

Does your TDI have two 40 amp fuses side by side in the fuse box? I am somewhat convinced that they are for the cabin heater.

My Canadian model has the two fuses. And yesterday when it was -10 C out I had heat coming out of the defrost vent in 2 minutes of idling, so I am assuming I have the heater.

The parking heater is a Webasto Thermo Top C diesel-fired coolant heater. It is most commonly found as an option in Europe and as standard equipment on the Touareg V10 TDI. It is amazing. ;)

I don't think the '15 have the electric 100A grid heaters, I don't hear any relay cycling on a cold engine on our 15 Passat as we heard on our Jetta and '12 Passat. Call it a cost cutting measure.

my 17 alltrack has the same check boxs.

Also parking heater is a wabasto type fuel fed cabin/coolant heater. Its an OEM option in those lands of VW not being a cheap economy cars competing with kias on price point.

Volkswagen may have thought that their convoluted new cooling system would get the cabin up to temperature more quickly than on previous TDIs. Based on reports here, I guess it isn't quick enough.

When I enabled the option in the ecm and applied it I heard a relay click then a fault was stored.

I do have the pair of. 40s installed in box.

How difficult is it to install a factory webascto?

There's an option in vcds to install parking heater without can bus. Whatever that implies.

Webasco is what I was telling you about in one of your other threads about heat. ;) It's SPENDY for the full kit but retrofit of the setup without full integration would be challenging but not "as" spendy as the full setup. Google is your friend.

The Webasto (W-E-B-A-S-T-O) sells for about $1,500 on Amazon and that isn't including any sort of installation or the additional parts that may be necessary to get it to work. It's expensive, for sure.

You could find less expensive used options on eBay or perhaps in the for sale section of a boat or RV forum.

Alright.

Next clarification is what exactly is the aux heater?

I see that in vcds too.

And confirmed. I disabled the electric grid in the hvac module and for as crappy as it can do battling subzero fresh air intake it was actually doing something.

I wonder why I can't do a basic test of the unit if it does work?


Blower on high, grid heater on, no lights, vcds was showing around 3200watts.

Blower off grid off, around 500watts

Maybe not the best thing for the engine, but after 5-10 min of idling on a cold morning with the heater on I get into a warm car.

Mid 20s in OkieVille ~~ got a *faster* hot cabin this morning

.... It was in the garage (as usual) Mid 20-ish out side. Garage 45-ish

.... and normally takes miles in drive to get the cabin hot.

.... it is 'bout 1.5 miles out of my 25 MPH residential area, before I hit the arterial streets.

.... more than a little POed at being cold, I punched it into S and held it in 1st gear 2,000-2,500 RPMs for 3-4 minutes.

.... saved at least 4-5 minutes of a chill

.... Sticky?

Sticky? Naaaaa

Also, I wouldn't hold 1st gear at 2500 RPM while cold. I *only* drive in S mode and I can tell you, letting the car do it's thing, shifting when it should, I have heat (put blower on 1 or 2) in 5min normal driving, in my outside parked car in 5deg weather. Once the needle is a 1/3 on the dial you can put blower on 3 or 4 and be good to go.

Now something I did find, with the wife and kids being home for break, my 2 passenger side vents only serve up cold air. :( I never noticed because those vents are usually closed, it's just me up front or kids in back. Wife was like, "I got no heat over here" and much to my surprise, no hot air at all on the 2 passenger vents. Owell, will take in and have it sorted out.

I use 2,000 to 2,500 RPM -- starting with the lower range (2,000) for 'about 1 MIN

The garage was approx 45 -- after we back the car out of the garage, and buckle up, that is approx 1 MIN.

In my residential 25 MPH zone there is no hurry.

We were (almost) toasty, a whole lot quicker than 5 MIM.

At any rate, going 11-15 MPH in a quiet (no traffic) residential zone as the car gently heats up is fine by this pitiful ol' geezer Okie :p

Oh, ok, sorry, I thought you were complaining about it. Ha ha. Totally misread the intent of your post. :D I'll tell you this, thank GOODNESS they modified the coolant circuit in these new cars. The MK5 (for sure) and surely earlier we're way slow to get heat inside.

Took this knuckle headed Okie a while to figure out how to operate my TDi

Figure I will still be learning stuff, a while longer.:confused:

Even doing the above warm up introduced me to the 1st gear TDi roar (noise level) of 2,000-2,500 RPM in an other wise quiet situation. No other cars, no wind noise. etc.


It felt like I had the power of a jet fighter. Even at 11-15 MPH. God I love my lil' Golf :D:D:D:D

I am doing a Webasto retro fit on my Jetta and learning very much along the way. I started a thread on it (prematurely) and will update it as I gain more knowledge. The hardest part so far has been getting the heater to actually fire up,as the heaters I acquired are CAN based units and I am trying to fire them as w-bus parking heaters. I think I will have to replace the controller with an earlier version with w-bus or analog signals. I have ordered a new controller from a specialist in Hungary, hope it gets here soon, it is getting colder every day. As far as mounting the heater on the car and plumbing it in, it doesn't look to be a very big problem.

My Jetta also has the electric grid heater and it works as good as it can, but more is needed in my opinion. if I were not the tinkering type I would probably live with it as is but....

I did spot a Webasto retrofit kit on ebay with supposedly all the fitiings and wiring you would need to install it as a parking heater with the programmable timer. From what I have learned on mine so far the kit looked pretty complete and viable. It was also marketed by someone in the US. Price was $850 ish.

Maybe once I get mine all figured out, I may offer kits too. I do have a few heaters. In either case it is not a project for someone lacking basic fabrication skills, even with a kit.

I remember driving my air cooled Beetle with a heavy jacket on and defrost set on full, hoping I didn't have to scrape the windows from the inside.

But those days are gone, and I am soft and lazy and want heat, dammit.

Really it is much more tolerable than my old Beetle, but if I can make it closer to a modern car I will.

I'm loving the instant heat of the 6,000 watt electric cabin heater in my Fiat 500e. Freezing half way to work in the TDIs sucked. ;)

Is the electric heater factory on that?

I would rather be cooler at 40 MPG in my TDI that toasty hot in my 4 runner at 16MPG.

If only I can get my auxiliary heater to work

Yes. Being an all-electric car, the only source of heat is electric.

And 20 miles shaved off the range.

When plugged in to a Lvl 2 charger, you can preheat the cabin right? At least you can on the Volt.

The electric companies recommend you keep the cabin preheated all night just in case you have a midnight run to the store ;)
