A trip back in time for us seasoned mechanics: Who can forget the vacuum and cable controlled water valves...

[@dlewis9760]

2011 CRV for me. This summer, no AC and it was blowing hot. "I'll give it a couple of days..." Well it "Fixed" itself. Come October, no heat or so I thought. Go to the Honda delar. Customer service guy says "You have heat, but it's realllllllllllllly slow." Forget what the price was, I don't pay attention when I need something and I have the means to pay for it. 2+ weeks on backorder. He wasn't sure if he'd get one in a month. Then another week or so for an appointment. The heat did work. From cold, the cabin would get warm in about 15-20 minutes. He also said "If you turn the heat off it will go off, but it will take forever again to heat up". Hot engine wasn't too bad, maybe 4-5 minutes. I told him my first wheels was a air cooled VW Beetle and cold wasn't going to stop me. He said "I have you beat. I had a VW Thing". He also said "In the good old days, we would forced it on hot until the part comes in. But 'electronics'.....".

[@wernerdanler2742]

My 98 Volvo had a vacuum controled valve. If I remember right, it's normal position was open and closed with vacuum when you started the car. In the hot summer it decided it didn't want to close, so I got a piece of hose and clamps and bypassed the heater core and left it that way.

[@JamesAgans]

I'm 78, and I do not remember any cable controlled water valves. I do remember the clock spring type heat risers on the exhaust manifold and choke plate though.

[@jamesevans7537]

[@angelr8892]

Was asked for opinion on an overheating 2009 Jetta with sideways 5. Was fine in winter, overheated when weather warmed. One hot radiator hose, one warmish, so guy replaced thermostat, said it was a tough job. Same thing. Next he was going to try water pump, but that would require lifting front of engine, he wanted my opinion before doing that. I told him since one hose was getting hot, didn't think pump was problem. I did a lot of research, finally found a post by a mechanic who fixed similar problem, said it was clogged heater core (no valve on these). Said the way the thermostat housing was designed, if no flow through the hose leading to the heater core, thermostat would never open?!? Checked heater core hoses, one hot, one cold! As a test, bypassed the heater core, both radiator hoses got hot when thermostat opened, mystery overheat fixed. He left it like that, planned on replacing heater core before the next winter. RnR youtube vid showed tiny passages in heater core, no wonder it clogged, especially with the "lifetime" coolant these use. If you have a mystery overheat on a VW product, run the heat and check heater core hoses to make sure both are hot. If not, investigate why.

[@mikechiodetti4482]

Nice quick fix Ivan. Leave the valve out unless the A/C performance suffers in the summer.

[@Sandmansa]

I've noticed that was a fairly common issue with Mercedies and BMW. The heater control valve just dies and well, no heat. The metal body control valves were much better. But the plastic ones like what's on this Audi, burn out after a few years. Awesome job Ivan! Lots of people wind up just eliminating them as they are not really needed. Oh, about the low air flow from the vents. Do the customer a solid and replace the cabin filter. It's very commonly overlooked.

[@GregoryGlessnerViolin]

The heater subscription must have run out.

[@justinnethers7198]

[@PineHollowAutoDiagnostics]

Thank you!

[@axelraver]

He forgot to pay for the subscription 😂

[@Peter_Riis_DK]

Deleting the valve might present a problem with cooling in the summer, but I believe it's main function is to isolate the aux cabin heater from the engine. This russian fix probably results in a much longer warm up time for the cabin. Anyway, they don't fit a valve just for the hell of it.

[@ferrumignis]

The same valve is used on numerous other VAG cars and whilst the original Audi part is quite pricey (around £200 in the UK) there are some reasonable quality aftermarket parts (e.g. Pierburg, Gates) that are around £70. Since it seems quite an easy job to change and a part failing to work is not going to cause expensive damage, I would be less concerned about using aftermarket in this case.

[@joekuntzman4016]

Great work! You didn't get bogged down in the fancy system, and kept a simple coolant flow diagnosis to the end.

[@thomasdemarco617]

a/cwill have to cool the heater core would replace the valve great diagnosis

[@ford6]

My Land Rover had a similar issue. After I had the engine rebuilt. Rebuilder put a 192° thermostat in, the car specs for 198°. The heater bypasses until ~194° (fast heat up for emissions). So idle and some "spirited" driving would get some heat generated putting the proper thermostat in fixed it. Also max heat is now dubbed "gates of hell" as I had replaced the heater core thinking it was clogged as only the input side was getting hot. (This was when I learned that the core had a bypass thermostat)

[@cullenmiller8170]

Nice video and easy diagnosis with the thermal imaging camera. I had a 1974 Mercedes 450SL that had no heat. The system had a similar on off valve and you regulated the heat with adding more outside air to cool the full heat down. I ended up adding a switch to turn the valve on and off. The center console and heater controls were beat up pretty good when the radio was pried out of the console and stolen.

[@gregwhite5058]

I keep trying to figure out whether people actually want all these fancy doodads on their cars or if it's just the carmakers adding more complexity so the dealers can make more money on all the repairs that will be needed and the carmakers can make even more money selling replacement parts.

[@Paramount531]

Not to mention replacement cars when the owners get too frustrated with their current one.

[@kennyfordham6208]

When you said that the cabin heats up, initially, then gets cold, I suspected that it was due to a bad flow valve. I ran into a similar problem, a few years back. The valve, that was causing my problem, was vacuum activated rather than solenoid activated.

[@johnt.848]

Great diagnosis, and fast. My old 2010 Lancer has a similar issue where I feel the heater isn't fully off in Summer and the AC isn't doing as well as it should. Maybe I should investigate where the heater core flow valve is on mine.

[@volvo09]

Seems like automakers add these valves for maximum AC performance (air handler box leaks) and as a side benefit they keep crud out of the heater core when the heat isn't needed, but i'm sure that part isn't a priority...

[@rkan2]

Also less stress or cycles on the heater core in theory... Don't want to be replacing those, especially in an Audi!

[@GreyRockOne]

Sweet! Love a quick painless fix!

[@DJ-tn7vj]

Love thermal energy. Good job and diagnose

[@sheerwillsurvival2064]

If it works it works. If AC is a little less colder in summer then buy the valve or live with it. Great job 👊🏻

[@timramich]

My AC doesn't blow very cold in the summer. They put the proper amount in and everything tests fine pressure-wise on a gauge set. When I first got it, it needed blend doors replaced (WJ Jeep). Stupid dual-zone control. Bought a whole HVAC box from a part-out and also the aluminum ones that someone makes. I replaced everything in boxes and had a shop do the swap. I suspect the blend doors aren't able to travel all the way. If it was me, even 5 degrees would be worth a $200 valve to get the most out of the AC.

[@haywardsautomotive6156]

Nice diagnosis Ivan. Simple bypass

[@mydimeisup5103]

Gotta say I loved the auxilary heater in my old Audi A4 2.0T. It would be around 32F in PA sometimes and within 1 - 2 minutes I would get air hot enough to cook an egg! My current Audi A6 doesn't seem to have it and I couldn't find anything in the SSP provided to technicians regarding an auxiliary heater, but at least I have supercharger whine and one of Audi's most reliable gasoline engines so a small trade off.

another brilliant diagnostic.

[@chillybrit2334]

My car (Skoda - also VAG family) has the auxiliary heat option. It's fantastic. It's a diesel engine work whip and all my prior diesel vehicles have taken an absolute age to start producing any heat from the vents on cold mornings, to the point I'd be sat there engine idling for up to 20 minutes just to blow the mist off the inside of the windscreen to be able to drive at all. This car, within a minute - hot air from the vents clearing the windows. I assume it's some simple resistive electric ni-chrome wire heater assembly in the air path - ancient tech with nothing to go wrong but so damn effective.

[@marty0715yt]

@@AraCarrano I know what you're talking about but that's not what I'm referring to here.

[@rkan2]

Some winter packages at least in Europe come with glow plugs on the coolant lines. Auxiliary diesel heaters have also been an option on premium models and even Skodas for a long time. You can of course always retrofit. Some people even fit them to their electric cars!

[@Techhead777]

It's been a few years, but my dad owned an 08' A8 and the heat did come up pretty quick as I recall, but than again the car was garaged. There was a way to run the climate control while the ignition was off for a brief time to heat the cabin, but the fan speed was limited to low or option 3 and it would eventually turn off after a period of time. I assume this used the auxiliary heat to continue providing heat with the engine off. I wonder if there was a limit to how high the fan speed could be and the aux heat able to supply enough with the engine running but cold? Granted with the ignition off, eventually that would drain the battery which was why the fan speed was limited and it turned off automatically.

[@rkan2]

@@Techhead777 That is not an uncommon feature with cars that have an electric water pump. Called "residual heat function"

[@thk7513]

This will be a great fit for the summer months.....the AC won't get cold. Russian hack not that good this time. You fixed the result and not the problem. Ivan go read Audi's theory of operation.

[@mopar6586]

Exactly spot on.

[@TheProtagonist_777]

How will the AC not work?

[@kenrieve9711]

This fix will work fine for a few more years until the blend door foam starts blowing out the vents. Then spend $200 on the valve or $3000 rebuilding the HVAC box.

[@TheOnespeedbiker]

The shut off valve stops coolant from circulating through the heater core from the aux water pump when the heater is not in use; I believe the auxiliary water pump is only turned on when the heater is in use though it may also be part of the Start/Stop system (if equipped). Further no air will be vented through the heater core unless the heater is turned on. While it introduces some heat into the HVAC system, it simply means the AC will have to work a little harder to cool the car. So it's a temporary fix unless it works. OTOH it is an Audi with 100,000 miles which means this is likely just the start of a laundry list of sub systems that will continue to fail.

[@PineHollowAutoDiagnostics]

Many cars don't have coolant shut off valves and the AC works just fine... That's what blend doors are for 😜

formerly a heater was a dealer added option

[@phprofYT]

My 2014 Ram diesel has an aux heater when in defrost mode to assist with defrosting the windshield on cold startup. Appears to be a common thing in newer vehicles. Only problem with removing that valve could be difficulty warming up in very cool weather. Perhaps regularly below 15F and sub-zero weather as well. On my Ram Ecodiesel I run a front grille cover in weather regularly below 40F (OEM says 32F is cutoff) to aid in warmup and heat retention. Then again 15F is a typical wakeup temperature for me :)

[@PhillipBailey]

Good diagnosis and I would have bypassed the shutoff valve as well. Just curious if the open circuit would set a code in the HVAC and whether you could bidirectionally control it with a scan tool.

[@BogdanTomu]

in eastern europe we install a common water valve and the work is done 😂

[@mikedoblo4782]

the temp should stay in the middle even with heaters on i think one of the thermostats is duff. the smoke could be a coolant leak, it fills the valley under the inlet manifold and when you brake it leaks down the front of the engine onto the belt. there is a small theremostat under there aswell. well there is on older models. the water pumps also have plastic impellers that like to fall off and they dont really overheat unless its warm weather going up a big hill. it mite also have the water pump that covers the impellers they can get stuck

[@hokie9910]

Another Audi….what a surprise!

[@tiredoldmechanic1791]

I suspect it actually needs that valve for the air conditioner to work. Many vehicles have the heating and cooling coils stacked so the air flows through both. They use the cooling coil in the winter to remove moisture to defog/defrost the windows. They use the heater valve to shut off coolant in the summer and cycle the AC compressor. It takes up less room than splitting the air flow.

[@PineHollowAutoDiagnostics]

Hmm so where would the blend doors go then? Usually all of the air goes through the AC evaporator, and then the blend door directs a portion of it through the heater core based on the desired temperature 🤔

[@tiredoldmechanic1791]

@@PineHollowAutoDiagnostics The blend doors will direct the air flow to the window, dash or floor depending on the settings and mix outside and cabin air into the system while using the cycling of the AC compressor and modulating the flow through the heater core to control temperature.

[@WarrenMillerIII]

@@PineHollowAutoDiagnostics if it’s like my BMW, that valve you removed is modulated on-off to achieve the desired heater core temperature.

[@eddiereichel9354]

I do love the russian repairs. Some of these vehicles are expensive to repair. Im sure that will be just fine until the summer when the heater core is hot and ya are trying to run the AC. I had a Tbird a lady wanted her AC fixed. Freon was empty. 2 orings right on top ford had them next day. Replaced and charged the system it blew cold as ice till the engine warmed up and heater core overpowered the AC. So I do some testing it has some fancy pants 6 port valve to control 2 zones in the heater core. Valve was stuck open and the solenoid was shorted. Replaced with Motorcraft part and boom AC worked great. Sent car back to customer and then she called couple months later when it got cooler. No heat. The controller of the valve is the ETAC heater control. Either controller had shorted the original valve or vice versa either way we had to get the heater controller repaired too.

[@alouisschafer7212]

Auxiliary heater in this car you say? Its a Webasto Diesel Heater then right? Thats most likely the smoke out of the engine bay you mentioned thats where these heaters are ususally located and the exhaust isnt far away then. Doesnt sound like it has an exhaust leak and a warmed up TDI doesnt smoke when idling. I had to do a full overhaul on the Ardic 912D heater in my 2007 Diesel Volvo because it started smoking and flaming out only to restart the flame with a plume of smoke to the point of me just pulling the fuse and leaving it be until I was ready to do that job. Its fuse No. 4 25amp in the engine bay fuse box for anybody interested BUT its Fuse 1 on earlier models. But Volvo labels their fuses really well actually so just look it up in the owners manual or in the fuxe box itself. The unit was serverly sooted up inside and the burn chamber was so crusty even my favourite oven cleaner could not cut it and that oven cleaner is agressive parts left to soak in it for a few hours look better than new because it completely dissolves surface oxidization. Had to to a few soak and wash cycles with the cleaner and sand the burned in crap off with sandpaper 😅 The heater was also all wet and sticky inside >unburnt fuel... running rich = stinky smoke so I replaced the fuel pressure regulator/nozzle assembly. I got everything so clean that it literally started with zero smoke the first time and no exhaust smell at all. Now it takes 60 sec to fire up, 2-3 Minutes until warm water reaches the heater core and from there on the coolant temp really picks up quick. These older Ardic/Nordic branded heaters (in reality the company Ardic was bought by Eberspächer in the early 2000s) are really reliable and well made units, its unusual for them to need more than a basic cleanout and a new fuel nozzle even when they are now 15-20 years old. Parts are reeaaly expensive and not easy to get (basically the only way to get them is to buy original Volvo parts) like the fuel nozzle is 150$ alone. There are rare instances where the fan motor dies or parts of the wiring harness start to kinda smolder and short out where they enter the stainless steel housing of the heater. You need to make sure the wires are NOT pinched and free to move when reassembling these heaters. That same heater was also the standard auxiliary heater for Audi back then, some! other VW models and it was used in some small yachts aswell.
