Aux Heater

[Stevec0268]

Morning all,  hope someone can help with this nigly little problem.

 

On these cold mornings the Aux Heater on 2005 2.8 Diesel comes on as it should.  Now I can't tell any difference in the speed in which the engine or interior egts up to temp compared to when the heater doesn't come on (i.e. when the fuel level is below a quarter tank).  Also I can be driving for at least an hour on motorways and it doesn't turn off.  The temp guage is sitting just below half way so no problems with the thermostat.  The only way it will turn off is if I get the car up to temperature, pull over and stop the engine and then re-start and it doesn't come back on.

 

Don't know if this is a common thing or anyone has come across it before, if so is there a way to make it turn off when up to temp?

 

Any help greatly recieved.

Steve

I have the same problem with my 2006 2.8 g.v. I find that I can turn off the aux heater by reducing the temperature control by 10 deg. Then turning it back up when the heater has turned off. Generally speaking though the heating system is not good and takes ages to get up to temp. Not looking forward at all to the really cold weather.

I've got pretty much the same. It was minus something or other this morning & although the aux heater indicated it was on it didn't seem to make much difference.

To turn it off just lower both temps a few degrees then set them back to normal.

Hi,

Yes with the temperatures getting colder it's staying on a lot longer, on my morning run in this morning (2oC) it didn't cut out at all, temperature was just under half way mark and I had climate control set to 22oC.

You could add the 'winterise' kit to the front, i.e. blocking part of the radiator up, as these engines are cold runners and by blocking part of the radiator front it helps retain the warmth. I've just done that to mine using QinteQ's technique of using pipe insulation (the foam stuff in long tubes). Just cut it to size and push it into the gaps, it looks decent and helps it get to temperature faster.

 

Having said that, it should still be getting warm after a short drive with aux heater on, I get 'delay' on mine for approx 3 minutes on a very cold morning, when it turns on the temp gauge has moved to just around the first mark and warm air starts to come out the blowers so it starts warming at that point.

Why is 'not turning off' a problem ? It's a fully automated Webasto ThermoTopo. It's job is to protect the engine in very cold weather by assisting the engine's ability to get up to a working temperature more quickly. It's not a cabin heater as most think, costs virtually nothing to run and indeed saves money by reducing those first 20 more expensive minutes and metal wear when the big metal engines moving parts are not yet up to working temp.

 

I have to say in all my years this is the first ever time I've seen anyone wanting it turned off, normally people are begging for anyone to supply & fit second hand used parts for £200. Do as Andy suggests and 'winterise' your GV. Best of luck.

Hi QinteQ,

 

Just assumed it should turn off as never had a car with one before.

 

Thank you everyopne for their comments, you have put my mind to rest!

Its an expensive 'friend', an additional after-market extra people pay a lot for. Left to its own devices it will just work if (1) its cold enough and (1) if you are at least 1/4 full of fuel. If you really want it switched off get underneath the car and unplug the electrical connector near the unit, denied a power supply voltage it will go dead along with its brain. We all have to learn including me, all questions and answers are knowledge and that's why we use forums. Take care !

Webasto....Any kind of filtering system?... Work fine and as should. However I have fumes, first thought maybe manifold etc etc then noticed only when the aux heater kicks on in cold weather. Not noticeable when moving [obvious reasons]

Standstill window open lights or inside garage you will, it exhausts driver's door @ sill level. Any other suggests flexi pipe issue. Standard stuff but never bought a length. Yanks use both 5kW thermo and water top, try rockauto uk or any UK supplier of Flexi.

Thanks for that

Having it up on ramp next week [my local mot spot] to have sill repair and handbrake adjustment, good time to deal with this too.

Absolute pig to get good, UK test efficient is all that's needed. Two trick are:

 

.1. early issues with understanding 'top.hat brakes' years ago including PIC of small parts: https://www.chryslerforum.com/forum/chrysler-voyager-town-country-21/my-struggles-gv-handbrake-mot-22210/page2/

 

.2. a good YUK is mentioned this means engine running, level ground, brake fluid topped up, STAMP hard on foot bake and keep pressure on, then pull up hard 6 times to balance Y cable + clockspring assembly. If that's no good you need small parts/lotsa time/copperslip grease. Then YUK process again.

 

Best of luck.

Can I be lazy and ask location of the Webasto rather than crawl around....[maybe flexi prob...white smoke under bonnet..and fumes in cab, but only first start if aux is engaged otherwise not]
