davewill Posted January 22, 2007 Report Posted January 22, 2007 Ok, i know this is probably an Aux heat problem, but a bit of advice before i contact the Fraud dealer would be appreciated. Drove to work this morning on a 10 mile journey with outside temp at approx 2c Car temp warmed up as normal, but no heat inside car from A/C (basic A/C not climate control) No sound of jet engine, but no smoke billowing out either Took car out at lunchtime, and same again, just cool air coming out of vents Would you think this is an Aux heater failure, or is there something else i should be checking Thanks ps If it is Aux heater, how much should i expect to pay to get fixed?

NikpV Posted January 22, 2007 Report Posted January 22, 2007 did the little exhaust pipe from the aux heater get warm at all? Quote
davewill Posted January 22, 2007 Author Report Posted January 22, 2007 Don't know I'll go and run engine for a bit, and check Thanks Quote
NikpV Posted January 22, 2007 Report Posted January 22, 2007 I'm assuming it Vehicle Type: Galaxy 1.9TDI Zetec 2002 what happens to the temp gauge on the 10 mile run? Quote
mumof4 Posted January 22, 2007 Report Posted January 22, 2007 If aux heater nay working..may just need a new glow plug...... Quote
tim-spam Posted January 22, 2007 Report Posted January 22, 2007 Whether or not your heater booster is working, I don't know. However, if the engine coolant reached normal working temperature (around 90 degC), the heater should work. So , I would guess a non-operational heater control valve / flap, depending on whether you have a Mk 1 or Mk 2. It it's a Mk 2, it could be a problem with an electric servo motor - VAGCOM should be able to identify which. Quote
NikpV Posted January 22, 2007 Report Posted January 22, 2007 (edited) f car temp rose as normal (missed that first time round) then aux heater is probably ok - well not the cause of your woes anyway sorry tim I didn't see your post I appear to be having some issues with the forum not refreshing very well ATM Edited January 22, 2007 by NikpV Quote
Guest gooner52 Posted January 22, 2007 Report Posted January 22, 2007 hi dave what part of the uk are you in might be someone close,that has vagcom they can test for you m8 :16: Quote
davewill Posted January 22, 2007 Author Report Posted January 22, 2007 Guys, thanks for your input I,ve just taken the car for another run, and then checked the small output pipe under the passenger side of car. It is stone cold. The engine gets up to normal temperature on the gauge and the cars runs fine Its a MK2 (2002) TDI I am in Telford in Shropshire if anyone in near me Thanks again, look forward to more comments Dave Quote
tim-spam Posted January 22, 2007 Report Posted January 22, 2007 The engine gets up to normal temperature on the gauge and the cars runs fineSo, the heater should work without any help from the booster heater. VAGCOM is probably your best bet to diagnose the problem. Quote
davewill Posted January 23, 2007 Author Report Posted January 23, 2007 No heat in car again this morning, and kids are now complaining :) Have booked it into Fraud dealer on Friday, so will update when they do their inspection and fixThanks for your commentsDave Quote
Dave-G Posted January 23, 2007 Report Posted January 23, 2007 You would usually get some heat towards the very end of a ten mile drive witout the booster heater working and the engine reaching operating temperature, as the thermostat opens - particularly if it was in traffic and taking longer than a clean run at it. It sounds like you are reaching that threshold. A loger run could provide more information to work on. If the heater works it will produce a 'jet engine noise - and you'd also hear a 'jet wind down when you park up and unload the kids. The exhaust pipe of that heater if and when actually burning oil, will be hot enough to take the skin off your hands if you grip it tight - natural body reaction will prevent this from happening. You would also smell something very similar to aviation/parrafin fuel - there is very little differerence between those and diesel (mostly viscosity) Quote

If not then we can go from there. I have a freind who works for VW in Telford who has the box that just resets the fault codes so that could help you. Do you know Newport at all? Chris Quote
davewill Posted January 23, 2007 Author Report Posted January 23, 2007 Chris I actually live in Newport I am at home at the moment If your friend has a "box", maybe he could advise ThanksDave Quote
mumof4 Posted January 23, 2007 Report Posted January 23, 2007 Aux heater doesnt work on my gal and it takes nearlt half an hour for the cabin to start getting hot air..and just a wee bit longer for the temp to rise to 90 on the gauge on the dashboard..i am assumeing this is allbecause of the aux nay working.....bummer....bloody steering wheel was freezing this morn..was steering with fingertips till my hands froze then it didnt matter..

Have you seen those things that you can put on your hands ..... wool or linen i think they are made from .... anyway if its cold and you put them on they keep your hands warm ....... gloves I think they call them Maz Quote

davewill Posted January 23, 2007 Author Report Posted January 23, 2007 (edited) Chris Got your PM, but don't know how to reply to it (bloody technology!) Thanks for your offer I live about 5 mins drive from where he lives, so i could popm round to his house if he's OK with that Thanks again Dave sorry hun..nay allowed to post phone numbers on here..i shall pass it on for you.

Guest stawarz Posted January 23, 2007 Report Posted January 23, 2007 Damn, after 3 winters with no heating troubles and now suffering the same as everyone else, the auxillary heater not coming on. Seemed to have happened after the heavy rains we had a week ago and having to "ford" through deep puddles on roundabouts. Damn cold this morning, took about 10 miles to get to 70C and after 20 miles of dual-carriage way driving a tad short of the normal 90C but as soon as it came to the final 2 miles of city traffic back down to 60'ish (the raditor was cool so highlights how important that aux heater is for keeping the cabin warm!) Hope it's just a reset needed to get it going. Has anyone had experience in doing this with VAGCOM on this group (have ordered the cable last night)? Quote
Dave-G Posted January 23, 2007 Report Posted January 23, 2007 Booster heater aside... Although someone has taken me to task for this previously - I suspect the Galaxy cabin heating system takes its supply from the cold side of the thermostat which barely opens in winter. Ford/VW bumph say the engine is so efficient it dont produce enough waste bolliks and spam. The basic PD engine is also used in other (saloon) cars that dont have the problem and my guess is that the layout of a saloon car somehow allows enough space? to enable the cabin heating system to draw from the hot side of the stat. Quote
tim-spam Posted January 23, 2007 Report Posted January 23, 2007 The heater circuit on the MPV's is very similar to that on the saloon cars fitted with the TDI engine. The thermostat does not prevent circulation of coolant through the heater matrix, and it is true that these engines do not produce enough waste heat at low loads to achieve a coolant temperature of 90 degC in low ambient temperatures. The main difference is that the MPV's have a cabin that is around three times the volume of a typical saloon car - hence the need for a booster heater (and an auxiliary heater at the rear). The saloon cars get away with glowplugs in the coolant circuit to overcome this problem. Quote
Dave-G Posted January 23, 2007 Report Posted January 23, 2007 That sounds a well informed explanation tim - Thanks for that. Quote
davewill Posted January 23, 2007 Author Report Posted January 23, 2007 NEW DEVELOPMENTAfter driving for over half an hour this morning (and the car water temp being at 90c for a good 20 minutes of that) heat started to come through the vents Left the car at work from 2.00pm - 5.30pm When i left work, no heat on the 20 min journey home Do you think this is a thermostat problem, or more seriousThanks Quote
