[gregers]

ive just checked,i can see the pictures on page 6,im thinking if you cannot then maybe its because your a newbie,you need to make a few more posts then all should be ok.

Ok - sorry I was looking in the wrong place - doh!

 

Anyway - that's fantastic work putting those up - the job looks doable. Mines a Sharan, so I hope theres not too much difference.

Just to inform any other would-be- aux heater fixers, I have been told by VW that I need part 7M3963319A AT

Hi Andy

It does sound from your previous posts that you are only reading your fault codes and not clearing them, the heater is probably locked out and you need to clear the faults codes before it will start

 

The code reader I have is a maxiscan 405 now it allows me to read and remove the fault codes, now today I was looking at the rear brakes (handbrake mech playing up) anyway I checked the the pump feed next to the fuel tank and nothing on my test lamp so I powered it up with a 12v feed and it clicked I even disconnected the the fuel line on the heater hoping to see fuel coming out but nothing. I then took the heater apart to check the fan and it moved freely so not seized I checked all the fuzes, the temp sensor on the wiper mech so IAM THINKING THE TEMP SENSOR IN THE HEATER OR FUEL PUMP any ideas welcome and thanks for the replys.

 

Gary got your pm but sorry mate Iam going to use the old on another project.

Hi Andy

So when you clear the overheat fault code when does it come back? ie, after a start attempt, comes back straight away without attempting to start.

Am not familiar with your maxiscan so not sure if there's a compatibility problem here, perhaps other members can confirm? do you know someone local with Vag-Com who can double check your codes?

The fuel pump is controlled by the heater control module these are troublesome on the later D5WZ-F model not heard of any problems with the heater temp sensor's although there's always a first

HI THERE I THINK WHAT IAM GOING TO NEXT IS TO INVESTIGATE WHY I HAVNT GOT A FEED TO THE PUMP NEXT TO THE TANK. IAM GOING TO GO THROUGH ALL THE FUZES AGAIN AND EVEN HAVE A LOOK AT RELAY 17.

 

CHEERS ANDY

[ANDY545]

WELL PULLED THE FUSE BOX APPART TODAY LOOKING FOR RELAY 17 WHICH IN THE HANDBOOK SAYS AUX HEATER, WELL THERE ISNT ONE THERE AND NO WIRING FOR ONE SO I THINK I WILL INVESTIGATE THE TEMP SENSOR WIRING/PLUG/SENSOR. ANY IDEAS ON HOW TO TEST THE SENSOR PLEASE.

 

REGARDS AND HAPPY CHRISTMAS TO ALL ANDY

[ANDY545]

HI THERE WELL ITS ALIVE NO NOT REALLY BUT MY HEATER IS UP AND RUNNING,THREE DAYS NOW AND THE WARM UP TIMES HAVE HALFED. THE PROBLEM IN THE END WAS SOMEBODY ELSE HAD BEEN INSIDE THE HEATER AND DAMAGED THE PLUG WHICH GOES INTO THE PCB AND THE TWO PINS FOR THE TEMP SENSOR DIDNT CONNECT WITH THE PCB SO REMADE THE CONNECTIONS AND TRIED AGAIN ONCE I'D CLEARED THE FAULT CODES AND IT WORKED THANKS AGAIN FOR ALL YOUR HELP.

I have a (facelifted?) 2005 MkII TDI 130 (93k miles). I noticed that it wasn't warming up on my 15 minute journey to work last winter, and thought this was normal as I only got the car in September. I have had flame outs registered in VAG-COM and cleared these, however the outside temperature is now not warm enough to activate it. I understand it should come on below 10C (or even 5C). Does anyone know if the external temperature sensor that the heater uses to determine this temperature has been moved on these models? I'd like to dip it in ice and try and trigger it. I guess I've got a D5WZ-F heater but won't be able to tell until I remove it.

 

I have recently freed the wiper spindles as they were starting to seize and didn't notice the external temperature sensor that seatkid pictured in post #455 on Page 31 of this thread. The panel that surronds the wiper spindles is also one piece that is the full width, rather than the 3 section one that appears in the early pictures of the wiper linkage thread, which I only read after putting everything back together and patting myself on the back, so didn't check at the time. Sigh! If it's moved I'll post a picture of it's location once I find it!

 

While I'm at it my coolant temperature sensor is intermittent (VAG-COM) is this likely to affect operation of the booster heater? Is this the one used for the coolant signal. I noticed that the cooling fans were running as soon as I started the engine just before I had the radiator replaced.

[gregers]

im sure within this thread it will tell you where the sensor is,iirc its under the wiper skutle.

Hi gregers,

 

Read the whole thread, mentioned the location seatkid posted above in my post above. As stated I didn't notice it when I removed the wiper assembly (I admit, it doesn't mean it's not there though). That's why I was asking if it has been moved on the later models before I take it apart again. Can't even find it mentioned in TIS 2004!

 

Thanks for the response, I'll just have to look next time! Hopefully tomorrow.

 

Cheers,

 

Richard

Hi

Yes the MK2 is below 10 deg c the pic that Seatkid posted is the correct location but it's not normally hanging, it's in a plastic clip attached to the wiper linkage, so you need to remove the scuttle tray to access it, it will not be visible you will have to feel for it which is why you missed it before.

Don't bother putting sensor in ice just unplug it and bridge the two terminals of the plug with a short length of wire, this will ensure the heater fires up and stays running while testing for correct running.

 

The odd flame out for what ever reason will not stop an attempt to start but five sucessive flame outs will cause a lock out and will need to be cleared before further attempts to start.

 

You also need to check the electric run on pump is working, this is located behind the fuel filter on the bulkhead, you should be able to hear it humming after turning off engine, if you cant hear it then it's probably not working.

 

Coolant sensor wont affect cold start of heater but may interrupt a warm/hot start.

 

If aircon is set to auto then cooling fans will run regardless of engine temperature.

 

See how you get on, there's lots of info on cleaning and changing glow plug on booster heater in the FAQ's also changing brushes on run on pump.

 

Or of course just ask :lol:

[SilverBeast]

Thanks chrispb123456

 

That was just the info I was after. Didn't notice it last time as it's on the back of the harness. Shorted out as suggested and my booster heater came on fine. :blink:

 

My run-on pump is not working however, so I've just ordered some brushes. I'll do them when I replace the coolant temperature sensor, it should give a bit better access to that while the pump is out. Then there should just be the air-con to sort out!

 

Thanks again

Richard

[daddyfixit]

i've done brushes on my run on pump , i had to file them by hand on a sheet of emery and it does work !!!!!

[cheekys0d3]

thanks chrisb

 

hans motors has been taken over by GSF, i bought both the Glowplugs they suggested. on the condition i returned the one i didnt need. They were cool about that.

 

but unfortunately for me, both were wrong. so left the car half opened at a mates garage.. oops.. off to GSF tomorrow. going to insure i get the part 0 100 226 340... thought the pros knew better.

 

i guess u live and learn.

Maybe try here, http://www.vwspares.co.uk/product_info.php?products_id=54

Delivered next day for me

[gregers]

i had this problem with them aswell,the 1s they have given you no doubt are for the engine and as you have found not for the aux heater. :rolleyes:

[rwtomkins]

Here is my experience of changing the plug.

 

I was getting billows of white/grey smoke for the first 10-15 minutes after starting up. It would settle down after a while but it was getting too embarrassing in that first 10-15 mins so I decided to try changing the plug.

 

I bought a new one without wires from here:

 

http://www.vwspares.co.uk/product_info.php?products_id=54

 

This is the Beru GH001 aka 0 100 226 340 and it is the new-style replacement for the older 0 100 226 228. However it does NOT have wires attached. (I didn't want the wires because I have an older Gal, a Mk II from December 2002.) It shows up at

Completly changed my heater for a new one yesterday, its a big job, never done anything like it before and it took me about 2 1/2 hours. I didnt raise the car on anything, just slid under the back, bolts came off easy enough, but it was VERY dirty. Hardest part for me was having plyers big enough for the jubilee clips on the hoses lol. Now ive just got to wait for the temp to drop to 5c for the damn thing to kick in so I can tell if its working lol.

You shouldn't have to wait to long Dave, it's down to zero here this morning, frost on the screen etc :wacko:
