a18nkd Posted April 7, 2013 Report Posted April 7, 2013 Hi all a few little problems with my aux heater I need to change my glow plug I had the heater out from under the car but was struggling with the screws that keep it together they are rusted to the point of no return think I will have too drill them out and put new in does anyone know the sizes/threads so I can order the screws and glow plug the unit is a Eberspacher D3WZ does any one know where I can get one from or the actual part no. so I can go to local parts place thanks for any help Quote
xavier Posted April 7, 2013 Report Posted April 7, 2013 Search on ebay for eberspacher screws. I need some too, however have decided to wait until I actually get the unit apart before ordering parts. Currently I have the end off, 2 screws still in holding the exhaust port on! Quote

Have attached the Eberspächer parts list for the D5WZ which is the same apart from the controller so you can decide which screws you need Edited April 8, 2013 by chrispb123456 Quote

a18nkd Posted April 9, 2013 Author Report Posted April 9, 2013 what were they like for price wise? Quote
a18nkd Posted October 2, 2013 Author Report Posted October 2, 2013 Hi all update I have the hydronic D3W Z aux heater can any body give me the OEM (original equipment manufacturer) of the glow plug as the one I have is a BERU 0 100 226 228 8v and the bloke from parts place said he needs the OEM code to cross reference it please help and thank you Quote
chrispb123456 Posted October 2, 2013 Report Posted October 2, 2013 VW number is7D0963319 The beru number GH001. 0100 226 340 Quote
xavier Posted October 2, 2013 Report Posted October 2, 2013 So, can the holes be drilled out and fitted with helicoils? I think I read chromedome did this on another post (or is it depentant on the type of heater?).Ta! Quote
a18nkd Posted October 3, 2013 Author Report Posted October 3, 2013 Hi so is the one that is already in the heater the wrong one as that says BERU 0 100 226 228 yet the code you have is and the one you have put on says BERU GH001,0100 226 340 also the one that is on says 8v at the end is this the voltage and should it not be 12v ? thanks again Quote
chrispb123456 Posted October 3, 2013 Report Posted October 3, 2013 0 100 226 228 was the original plug when the car was new and was carried on to the early mk2, this was then superseded by 0 100 226 340 but still available on ebay. http://www.ebay.co.uk/itm/EBERSPACHER-GLOW-PLUG-for-D3WZ-D4WZ-D5WZ-HYDRONIC-WATER-HEATERS-FREEPOST-/181214092635?pt=UK_CarsParts_Vehicles_BoatEquipment_Accessories_SM&hash=item2a31339d5b this is now updated by the ceramic plug with wires attached to it and involves modification to the wiring inside the heater iirc this is the only one you can get from VW now for the D3WZ & D5WZ and it's quite expensive. http://www.ebay.co.uk/itm/Eberspacher-Glow-Pin-D4WSC-D5WSC-12volt-/280644230835?pt=UK_CarsParts_Vehicles_BoatEquipment_Accessories_SM&hash=item4157b31eb3 8 volts is usually marked on the plugs for these but advertised 12 volt hope that helps.

a18nkd Posted October 3, 2013 Author Report Posted October 3, 2013 cheers chris think i'll get the top one off ebay as my heater is the D3W Z thanks for the links it saves me a head ache looking for the right one thanks again Quote
SilverBeast Posted October 3, 2013 Report Posted October 3, 2013 So, can the holes be drilled out and fitted with helicoils? I think I read chromedome did this on another post (or is it depentant on the type of heater?).Ta! I have a late (2005) MKII with a D5Z-F which I have stripped and rebuilt. Just about all the mounting and plastic cover fixing screws had to be drilled out. We successfully helicoiled all the holes and I replaced all the screws/washers with Stainless Steel from ebay. Just need to get it working now!!! Quote
xavier Posted October 3, 2013 Report Posted October 3, 2013 Thanks silverbeast! I dunno, chromedome / silverbeast - is it wrong I got you confused?! either getting old (or drinking too much home brew!) Quote
xavier Posted October 3, 2013 Report Posted October 3, 2013 ... or maybe your avatar pic is adding to the confusion! Quote
SilverBeast Posted October 4, 2013 Report Posted October 4, 2013 (edited) You may have read that chromedome did this. I can see why my avatar would add to the confusion!Someone at work drilled them out with a pillar drill and did the helicoiling as he was quiet and I was rushed off my feet.

richyrich Posted October 4, 2013 Report Posted October 4, 2013 A note to anybody fixing their auxillary heater, or even to those with a working one - Fit a switch in the circuit so you can switch it manually from inside the cab..I found that the unit was cycling on and off too much during cold weather - which is no good and soon ruins the glow plug and gums up the chamber.It switches according to water temperature and outside temperature - can't remember the settings. I think other forum members may have done this already. Rich Quote
gregers Posted October 4, 2013 Report Posted October 4, 2013 make sure your run on pump is working,mine cycled when it went bandy. Quote
xavier Posted October 4, 2013 Report Posted October 4, 2013 > You may have read that chromedome did this Nah, it was you silverbeast, I read it last week! Quote
a18nkd Posted October 5, 2013 Author Report Posted October 5, 2013 what's these helicoils people are on about as I had to drill my 65mm allen key bolts out as someone has try'd taking the heater apart before and just had one bold holding heater together and just put epoxy resin in to make the other look like it is in Quote
richyrich Posted October 5, 2013 Report Posted October 5, 2013 A helicoil basically replaces the damaged thread in the hole - it looks like a spring but it's not - if you know what i mean.You have to drill the damaged hole out and thread it with an oversize thread, the helicoil is then wound into that thead using a special little basic tool and you should be back to having an original sized and type of thread.Basic, but you need the right sized drill,tap and helicoil kit. Quote
chrispb123456 Posted October 5, 2013 Report Posted October 5, 2013 Helicoils can make a good repair, problem is there not a lot of room for mistakes the alloy castings are very fragile and you will be drilling very close to the edge of the casing so a pillar drill is essential and the need for accuracy drilling the centre of the broken screws/bolts.
