I BOUGHT AN ABANDONED VW TOUAREG V10 TDI!!

[@rossirving7172]

I’ve got a 07 v10, the battery system is a little complex on these cars. Battery under the passenger seat provides power to all modules, you can jump this using the engine bay terminals. The battery in the boot is just for starting the engine and only connects to the system when the key is turned. The volt gauge on the dash only shows the voltage of the battery under the passenger seat. If that battery is not supplying more than 10v to the modules they won’t talk to vcds. A lot of electrical gremlins clear up with a fully charged battery.

[@ashleyclough5917]

The man with the info! 👍

[@deep4730]

That's a good head ups!!

[@rossirving7172]

I’ve already had similar issues and replaced the battery under the passenger seat. It’s a big one 950cca 110Ah, won’t find in Halfords! 😅

[@danielmorrissey5842]

Hay lad i have 3.0 v6 tdi and i have no battery in boot and its starts and runs away why is tis my starting battery i might swap tmorrow to see will she start with it in boot mine seems bk words:( lol

[@rossirving7172]

Hi Dan, the twin battery setup is only for the v10 Touaregs. V6 will only have the one under the passenger seat.

[@giorgostzavaras5686]

Frankly, I would like to see this thing come back to its former glory. These are truly awesome

[@nomadnomad9517]

Not with a V10 though. That engine was flawed from the start.

[@jeremybevan5946]

Hi Dean, Before you test the ECU look at the immobiliser module as when these go faulty they stop you connecting to the ECU. Its worth spending time on this car and when you sort out what may be one electrical fault everything else will seem straight forward.

[@imranyaqub1790]

More content on this V10 please Dean. Speak to Darkside, see if they'll help out, or a collaboration with Diagnose Dan. Either way, you may hate it, but worth the work just for the sake of getting the V10 running good again. Looking forward to more on this 👍🏼

[@janniss6401]

The important battery on these is the supply battery under the seat. The one in the boot is only for starting the engine. Touaregs and phaetons are extremely picky about battery’s. Slight low voltage and not using AGM battery’s can cause any electrical problem you can possibly think of. Also charging the rear battery does not charge the battery under the seat, as it’s only connected when in use or being charged by the alternator. You can charge the supply battery from the terminals under the hood, but you’re technically not supposed to, as it can also upset he cars electronics

[@andrewmacfarlane9448]

Agreed. I've now installed a 60ah 1450ca lithium battery under the seat. Fixed all my hot start issues. Battery only weights 8kg too.

[@alexp893]

Indeed - there are TWO batteries in these and it is crucial they are both fully charged and in perfect health; these cars hate low voltages. Check for water ingress in both front footwells - the sound insulation under the carpet holds water like a sponge and will slowly corrode the electrical components located there. I don't think it's a 2003 car. The headlights suggest it's a facelift 2006 and onwards model. What a wonderful machine and we will never see their like again so you need to save it! Get those two batteries replaced then take it from there. Cheers!

[@ben-lb4yt]

My dream car. Touareg V10 tdi. What a beast. Save this 1. I don't think they will ever make a beast like that ever again for domestic market. Diesel power all the way. Love your channel and keep up the top vids mate.

[@adamcharnley254]

Keep it as a dream mate, because the reality of owning one is a nightmare, great engine and that’s about it

[@ogalief]

I have a fully loaded V8 and absolutely love it (aside from the cost of ownership). If I were to have bought a new Corolla, I would be upside down the same amount of money in the end (factoring in maintenance and additional fuel costs). I keep mine meticulously maintained, and most people can't believe it's a 2005. You get way more for your money than a brand new Corolla too (except for Apple CarPlay and resale value). If you can afford a $20,000 car, I'd highly recommend a V10 Touareg (or W12)

[@bEEBO178]

@@bEEBO178 some people have lamborattos as their favourite car, some people like weird cars. Someday I wanna get a late 2000s Audi Q7 V12. It’s a 12 cylinder minivan. I find that more interesting than a cliche super car

[@andygj66]

I thought I was on a gardening channel at first with the amount of greenery going on! It’s an awesome looking car and the fault finding and diagnostics will make for fascinating content. It’s definitely worth saving. Apart from the tatty switchgear the interior looks okay. If you can sort that out it will be a nice motor.

[@ianrudge4580]

Battery in boot is only a starting battery. There’s another one under the passenger seat that runs the central electrics.

[@rivergate]

Yep. Beat me too it.

[@MrSausageT]

I think in order to recoup some money, you’ll have to do a diagnostic series. Looking forward to it. Darkside developments have done amazing work on these cars. They seem to make great off-roaders

[@mikedavies4387]

Darkside Developments are spot on with there work 👌

[@MattyEngland]

Check the fuses mate. Could be that the fuse is gone for the obd2 socket. You should have 12v on pin 16 at all times. If they are OK and you have an oscillascope, then if you check pins 6 and 14 you'll be able to see if you have a good CAN waveform. It should look like a mirror image, so as one signal goes high the other goes low. If you don't have an oscillascope then you could try unplugging modules one by one and retrying vcds, as if you have a bad module it can mess up the whole CAN system.

[@TheOriginalDaveJ]

Deano, check the footwells for water. If there's any modules under the carpet that have got wet, that'll play havoc with the electrics. Also check the side panels in the boot for water. Then look at the immobiliser module before going near the ECU.

[@Vespastendert]

Looks like the spare wheel well had some in it

[@daviewilson_1]

yeah samcrac had the same issue & it was a water logged module that made it light up like the xmas tree

[@ventouxR]

Windshield looks steamed from inside and boot doors were open, you can see light come in before he opens them manually (struts gone?).

[@billsheehy1660]

Love to see you get it up and running, like to see the processes that you follow. Its always helpful.

[@richardjones5255]

On another site I was viewing today, they referred to the 'comfort module' which comprised the immobiliser. Apparently this controls the communications, fixing and reprogramming that sorted the Audi in question.

Get it going and use it like you did with the Skoda! It seems to be a thing these days to take the fuse out that controls the OBD port on cars that have keyless start. May be worth a check.

[@markcfullam]

Fair amount of £ invested, and i think that V10 will be interesting to see what it will be like. Something different for the channel Dean, so i personally think it would be good to see what you can do to get it up and running. A good proper clean of the interior and maybe a refresh of the switches (so at least you can see what they are!) might be good too.

[@jimagnew1305]

I'm actually looking forward to see all the issues resolved. This will make great content

[@billymonkey111]

I love the little dance it thought you were doing with the door! I assume you weren't madly flapping about and the switch just has a loose connection

[@simonj3247]

Hi Dean, that’s got the new revised 2007 onwards front end on it. Possibly a lot of wiring issues in getting that new front end to fit / work for the guy who fitted it. My input - keep with it that will be an awesome car when done……good luck mate..

[@paulsmith3316]

Excellent video as usual. To get it diagnosed and MOT'd would be fantastic content on a rarely shown beast of a car. On purely economic grounds, it could be a money pit that you might not get any return on. Love this channel.....

[@poonabear]

I reckon a collaboration with darkside developments is in order. They know these inside and out. You could make it a nice offroader for yourself.

[@cianmacnamara6702]

I think the V10 has 2 batteries? Remember seeing this when replacing the one under the passenger seat on my wife's R5. Undo front bolts, seat tilts back nicely. Good luck!

[@andrewkidger7048]

Save this one Dean, will be a great project, might need to know the lawn first in the wheel wells !!, Great vid Dean, keep em coming.

[@mikecarver437]

I have one of these monsters, it's abit of a problem child but I can live with it. The v10 has 2 batteries, one in the boot and another under the passenger seat, I think the reason why vdcs can't read the car is because the battery under the seat is dead, this battery runs all aux and the battery in the boot starts the engine. Try charging both batteries, Please don't scrap it, do the right that by this rare beast and put it back as it should be. It will put a massive smile on your face when you pit your right down.

[@georgedaville4662]

I remember when this beast was launched. VW had a video icon showing the crank pulley with soundtrack of it ticking over, it said what does a V10 diesel sound like? It was hypnotic. I was totally sold on this car, ( but couldn’t afford it, or anything else much at the time!). Mr Sensible says bin it, but Mr I Love V10’s says sort it. Obviously had a Construction, agricultural or transport sort of dude owning it at some time, with rough hands, that scraped off all the interior trim! I just find the sound of that engine hypnotic, perhaps you should sell it as a living sculpture with a hypnotic soundtrack - different 👍😎😂

[@philbetts5963]

I have a 2004 V10. I bought it as a none runner. The engine ran but nothing else. I didn't communicate with vcds, which after careful testing etc was a combination of furred up contacts (from standing) in the main power relay next to the battery under the passenger seat and a faulty 'kessy' module. This is the keyless entry module which has two of the three can bus lines running through it. Faulty unit, two can bus lines down. From memory I couldn't talk to the transmission, the air suspension or the bcm. I repaired it with two transistors from Cricklewood electronics for about £17.00. If the kessy unit is playing up, it'll keep making the battery under the passenger seat go flat. Good luck👍

[@h3n488]

There's not too much European V10 Touareg content out there, so it would be cool to see you save this. Then go offroading with Darkside Developments people? 😄

[@cammmy]

Hi Mate, I have a V10 Phaeton and have a few pointers. The car has two engine ECUs and VCDS will not auto connect to them! you have to manually tell it what type of car it is. The door indicator will be the actual switch, try spraying some some brake cleaner in the latch mechanism and blow it out with air. They get dirty. It's worth looking the turbo seals and cams, both common issues and something you want to know about before sinking money into it. Cost me £2k in parts/tools to do the cams and mechanical pumps. The tools are hard to get as VW don't sell some of them now, so let me know if you need them. That whistling noise is likely a leak, mine doesn't do that.

[@geeks4hire]

Check your Terminal 15 voltages in the fuse box. The spare wheel well looks rusty as though it may have been full of water at some point in which case there are some connections in there which may be rotten and dropping the supplied voltage which would cause absolute havoc on the electrics. A simple fix if rectified.

[@BernardMogodu]

Which fuse box is terminal 15?

[@geeks4hire]

@@BernardMogodu You can usually pick up T15 voltages in all fuse boxes. Mine had dropped to

[@thomaspotkamp6768]

I say save this beast! Start by removing a bunch of interior parts and checking for water damage, check fuses and try to find out if someone else has had these kinds of problems before

[@reviewmaster4x467]

If its anything like the porsche cayenne look under the passenger side carpet. There might be corrosion in the wiring that may need cleaning and soldering. The carpet may be soaked from the air-conditioning over the years. Or it may have second battery under the passenger seat that may have failed.

[@davidg2073]

Hi Dean You should persevere and i believe the suggestion to check out the immobiliser is a good starting point before tackling the ECU. good luck.

[@cammmy]

Hi Dean, posting again just to make sure you see this. VCDS will not auto connect to these ECUs (there are 2 for the engine). You have to tell VCDS what car it is and it will then connect. I had the same thing with my Phaeton V10

[@geoffwalker1531]

Those problems scream water damaged modules. It may have been driven through a neighbours pond at some stage in a moment of madness. The Sills can fill with water and play havoc with the floor mounted modules. I know that from working on Cayennes. The drain plugs get blocked As mentioned already: Check Battery under passenger seat Check BCM and Comfort module The engjne wouldn't start if the ENGINE ecu was damaged

[@coggsy3036]

If I’m not mistaken I think these v10’s are the only car in its class that will tow a Boeing 747 airplane

[@marcinmichalski6837]

Since there is no communication with any of the modules, check if the diagnostic lines are not cut (sometimes run through a fuse that you remove). It used to be a security solution of sorts.

[@kevinjones1331]

My 07 Passat (160k) had similar symptoms 18 months ago.... * All dashboard warning lights illuminated with audible beeps. * Dsg stuck in 'P' * Electric parking brake stuck on. * Vcds not communicating. * Car jump started but would not move. I then did a running test on alternator using a multimeter...This confirmed low voltage output (Common on Valeo alternators).. Purchased new alternator brushes (ebay £12)...Hey Presto...All the above issues fixed...Drastic symptoms leading to easy fix... Not saying this is the cause of your issue but definitely worth testing.

[@rob86trott]

The drivers door problems are common. The wire harness gets damaged at the door hinge and its common for people to brake the fuel filler door latch cos it runs off the door electrics

[@ghulamsharif3399]

[@MrAvant123]

The green indicator on batteries only shows the SG of one cell and so is only a rough guide. Interesting project an unusual and complex car, but the fact that there are so many alarms may be a good thing in the long run as they may all be common. I would persevere as running right this would be a reasonably desirable car -- I think £2.4k was a bit steep though !

[@kippamip]

I love my Touareg. Mine is a 2006 V6 altitude and I absolutely adore mine. If you keep on top of these motors they are brilliant. The V10 is a great car with mechanical drive to the gearbox. Biggest problem with the V10 is the idiots that by them short term and rag them 0-60 and 0-100 all the time, keep them a few months then sell them on. Lots of gremlins with them electrical wise so you really have to keep on top of them. Can't wait to see if you get this car turned around they are very rare and sort after now.

[@dan2fast4you21]

V10 has 2 batteries, the one you saw is the secondary one that is only used if you use the key in the ignition turning it counter clockwise before turning it clockwise. The main battery is under the front seat.

[@dazndots]

It's a bloody Tank. Not liking that sound under the high revs though... This thing will hoover up puppies and small children. The battery under the seat might clear up a lot of issues for you mate get that on direct charge everything is pointing to that for the simple electric trips but this wasn't parked up originally because of a flat battery as you know. It sounds like Fragle Rock on a cold start and that's probably normal enough for these but my ear just hears money getting chewed up under that bonnet. Will make for really interesting content i believe but you might end up in a straight jacket after this lad. Good luck and keep up the great content.

Before you sell it, check out what Darkside Developments did with theirs. Absolute multi-purpose weapon. Pretty sure I saw a vid of it pulling a 40t lorry out of snow!

If it is a 2003 it has had a front end upgrade to the slightly newer shape. There is a common problem on the older cars of the wiring harness under the passenger carpet going up to the firewall degrading and causing all sorts of issues like you describe. Well worth saving if the mechanics are good.

[@brianfd622]

May not be ECU just the comms check power to grounds, start with the fuse box, had a vehicle not getting into ECU Saturday turned out to be a fuse, replace and if it goes again you will have to find the short, so good luck with that.

[@Roy_Wesseling]

It looks like the CAN network is down. As you can see at 11:46, K1 & K2 NO POWER when testing the VCDS interface. Might be some wires that are damaged? Or a single module that pulls the CAN network down. Or like someone said: something in the ODB port itself?

[@mickymac6571]

Replace battery (s) is the first thing I would do, especially secondary battery for electrics,( if it has one) Even with the engine running you may not be getting a good enough voltage to meet electronic requirements.

[@dubpilot1]

Those electronic issues can be caused by a couple of things #1 water leak onto harness or module #2 .

I don't think the suspension likes having doors open when it is adjusting, being keyless I opened my boot while working on mine but left my key inside! Shut the boot and of course it locked immediately. I had to smash the rear light and reach for that white release! Just FYI the drivers side turbo actuator can be changed from underneath if you need to but try and get both of the rod's clean and greased for a start. Others have mentioned the seat battery. The rear one will be fine.

[@Franksey180]

At 11:46 you did the VCDS test and it displays very dubious status for power, but you skimmed past it pretty quickly. Appears OBD has no power and needs troubleshooting, check fuses, battery level etc.

[@samoopsd]

From what I know of these cars, I believe there is a smaller battery under the passenger of driver's seat? I believe it's the one that is at around 8v on the dash? I think it's the one responsible for a lot of the more low voltage electrical on board stuff. I'm not too sure though as I've never worked on one!

[@hassanawan3537]

I've got one of these things, there's a main battery underneath passenger seat. You'll most likely still encounter issues until that is charged.

First is checking both the batteries have the correct specs for the vehicle and then if they're good I'd unplug both the immobiliser and body control module as not being able to connect says to me that there's something on the Canbus or K-line causing comms issues. With so many body control items not working I'd say there's a fair chance the Body control module is faulty.

[@jokerash]

I say fix it, it's fairly old to find parts for it at scrap. Because the car is running at least the immo , instruments and engine ECU are fine. The fact that you cannot talk with any module might be a lack of power at OBD connector and nothing else. Get the schematics there and see if you have power, sort the power if it hasn't any and check pins for Can Low and Can hi, you should have roughly 2.5 volts spiking up to 5v, that means CAN communication is alive. Also like others said, check for under seat and under carpet ECUs might have water and corrosion there which can play with things on CANbus.
