FIX UP THE QUATTRO! Mk2 Audi TT Haldex Gen 4 REPAIR DIY - ALSO APPLIES TO VW GOLF MK5 MK6 4MOTION 

Great video Andrew, I’d highly recommend the company I used them a couple of years back when my haldex control unit started to play up and threw a load of codes up on the dash of my Mk5 R32. Booked my car into the main dealer and they wanted around £1200 to replace the unit, after a quick call to auto fault finder he gave me great advice and once I’d stripped the unit off the car I’m sure it was repaired and back with me around 3-4 days later all sorted and only cost £160 😊👌

Excellent company, the Haldex controller on my S3 8p had a fault where the seal perished and let water and grit in. He fixed it and returned it within 3 days and it's been trouble free since. I buy my Haldex oil and filters from him and change them every 30k miles for peace of mind.

Thank you for including Haldex Repairs in you Haldex repair video. This is a really good job well done, and a very common issue with VAG Gen 4 Haldex cars around 50-60k miles. Enjoy the grip :)

Great video, thanks. Also I ordered a Haldex kit gen 1, with your discount voucher, for my 20 year old Audi TT 225 Quattro, so it can pull on all 4 wheels again, thanks to you.

Blooming awesome! Our 2010 Skoda Superb used to be great towing across grass. Last week it sat in the mud, on the flat, trailer disconnected, and the front just spun round.

Hello! Excellent video! Does it cost as much as the new filter seems to fit in? I see you have to pry it in. On the other hand, do you have to give an order to the pump by vdcs after replacing it? Thanks a lot! A greeting!

Just did my haldex service on my mk2 TTS today. I wish I had a lift because it would’ve been a lot easier - like in this video 😄 But it still wasn’t as bad as my mk1 TT. Those have that filter up around the top that’s a complete nightmare to get at.

Great video really informative! Used your discount code to buy the gen 1 service kit for my TT ! Thanks 👍

Great video Dr Volkswizard- what a difference it makes when spreading out the torque- love the workshop videos as intriguing how these systems work and how some wizardry can keep them at their best when main dealer maintenance can leave some systems like the haldex at risk - definitely a look with the on head camera lol 😝

Good information, but you overlooked the plastic filter screen on the end of the pump. It either needs to be removed and cleaned or replaced (there's a kit for it). There's a good write up on this topic in the UK Audi TT Forum which you can read here - www.ttforum.co.uk/forum/viewtopic.php?f=19&t=1850793. Just a little FYI on this topic - Audi included the Haldex oil and filter replacement in the 2006 Maintenance Schedule when the Mk2 first came out, but removed it completely in 2007 and then added just the fluid change from 2008 on. Most service shops claim the filter doesn't exist, and the reason for that is Audi actually changed the parts illustration and deleted the filter from the parts list. But if you look at the 2007 Gen2 Haldex parts list (see links below) it's clearly shown and the part numbers are listed. You can get the Gen2 and Gen4 filters (and pump screen kits) from Audi, but you may have to insist they look it up. Refer to the Forum post above if you need further assistance. Depending on the year, the MK2 will have either the Gen2 or Gen4 Haldex, with a transition period around 2008-2009. However it's relatively easy to tell which one you have by simply looking at the filter cover; the Gen4 has two screws, the Gen2 doesn't. Another point that's not obvious (since you're using a car lift) for anyone who does this service themselves, the vehicle has to be level when this service is performed or the fluid level will not be correct. Also, be very careful you don't confuse the Haldex drain/fill plugs with the rear diff drain/fill plugs. Even Audi techs have been known to make this mistake! 7zap.com/en/catalog/cars/Audi/brand/3/0 www.oemepc.com/audi/main_group/markt/RDW/modell/ATT/year/2007

Just done this on my 2006 Golf R32 and got the 2 clips in on top of the diff but the on on the side just above filter is almost impossible to get in It's a different type of clip to the other 2

Hi Andrew. Same on a RS3 8P? Mine just started to wheel spin today. Haven’t checked for codes yet.

I had exactly the same issue buying approved used from audi last year on a late Mk2 TTS DSG. Warranty picked up the bill at Audi £599.61. Good to see these cars can be worked on relatively easily. Just need the 4 post lift. Great VT. Thanks

That's the 3.2. I've got one great car. 👍 thanks for the vid .

Hi Could these get an air lock within them? I did mine the other day and could only get about 300ml back in and now when driving I hear a whining noise which I believe is due to lack of oil? But I can't get any more In there it just flows out straight away?

Brilliant thanks Andrew. I have a feeling i may be doing this myself next year

Hi Andrew just by showing everyone how to do this essential job, why take it to a main dealer when for around less than half price and if you are decent with some spanners it's relatively easy to do yourself. More vlogs like this would be very helpful.

Can you do this without VCDS?? Just by running the car after the inital fill and then filling some more?

I've seen on a service manual to remove 70mL after filling. Not necessary?

Also worth knowing Borg Warner supply majority of turbos for vag cars too.

The haldex unit exploded on my A3 3.2 . I now own a TT mk2 3.2 and I’m worried the same thing happens again. So found this very useful .Much appreciated.

Great video! I just bought a mk2 TT and realised yesterday that I'm not getting 4wd unfortunately 😕 mine is a 2011 2.0 TDI how would I find out what generation of haldex system is on my car? Thanks

great video andrew and very well expained .

It’s even worse on the mk7 golf with haldex 5. No filter, just a crappy gauze. I took my pump out at 12k (18 months old) and it was congealed and almost completely blocked. Probably saved the pump by cleaning it all out similar to your process here. Good video!

Great vid Andrew. You will be helping a lot of people realise this is an easy and cheap fix. Keep up the repair related content as well as the usual stuff. Enjoy this also.

Great video! Thanks for all the info

Will I be able to do this if I don't have the VAG KKL laptop software? Can I run the car in gear (in the air) to get the pump circulating the oil?

Thanks for the vid. Very useful

Excellent video. Will get my Cupra haldex serviced at 20k miles after watching this. Wish you were nearer to me in N Yorkshire and I would then use your garage

Good vid. Not sure its one for doing on the drive tho! We have an 08 Skoda Scout. Full dealer history until circa 90K and I'm not sure the Haldex has ever been touched. I did ask the Skoda dealer but it wasn't included in the standard service. Think the dealers skimped on the 2x "free services" I got when I bought it at 70K. Now on 125K. Perhaps I'm running on borrowed time. But getting the cam replaced (BMM engine) was an expensive rude awakening!

Good result Andrew, when the main dealer changed the oil in mine, I asked that they cleaned the filter too, was low mileage though

Access is everything! Can't imagine doing that on your back on a crawler! Great video! Keep driving AWD, when it's needed!

Great info and thanks for the insight. Having experienced Haldex failure on a RSQ3 and now owning a S1 I'd really like to avoid a similar situation by some good old maintenance above the manufacturers recommended interval. Without VCDS and a decent car lift I don't think this is something I can resonabley attempt myself but I now have a much better idea how much it should cost at a specialist service centre. My question is what is causing the 'gunking up' of the filters? Is it the Haldex clutch material? If it is I guess the shorter service interval than recommended depends on if the car has been driven in a way that gets the Haldex to activate more regularly than the manufacturer expects. Either that or they have a nice failure mechanic built in.

I have a noise coming from differential when driving what can be issue

Recommend you do a video on the DSG gearbox failures in VW Audi . I have personal experience of this in an Audi A3

I have the mk2 tt 2.0 tdi quattro so what Haldex system do I have so I can service it 👍

You didn't show it in this video but I attempted this today and the two 4mm bolts holding the pump on both snapped just past the head of the bolt. So 80% of the thread is still in the pump lugs and diff housing. Obviously can't get the pump off with it still being threaded. I've had enough with it for today

Good video I'm looking at getting a golf r estate next year so now I know how the haldex works

Quality and informative. Great job as always Andrew.

Hi Andrew, thank you for the informative footage. Is this TT going to be for sale?

Hi Andrew think my r is suffering this issue keep at low gear pulls am getting traction light flickering and wheel spin .. iam in south Yorkshire not sure who to use to eny more for this job as the dealers dont seem to no eny more ..they said no warnings lights on dash it will be fine .had haldex oil change at 30k at vw now approaching 50 k eny recommendations up south Yorkshire way I could use ? Very gratefull ..

Really enjoy your garage videos Andrew 👍

Hi interested In my Halden being done Would come to you A3 3.2 Let me know

Theres something wrong with one of your microphones. At certain points on your videos it only comes through one of my headphones. Only happens on your videos.

Does this apply to a 2013 ttrs?

Really useful video thanks!

should really be using odis or vcds to prime the pump prior to driving and recheck the oil level

Good video what's the best way to clean the engine my R is 3 years old time for a refresh.

Hi Andrew. Where are you based in Bham? Do you do work for customers or is it just your personal garage? Would deffo love to have a personal trustworthy mechanic for my car. Thanks for your great vids, Andrew.

Thank you Andrew....excellent

How much do you charge for this job to be done. I'd like for this to be done by someone who knows what they're doing? If so what part of the UK are you based in.

Hi, superb video, when can you book me in? 😂 Great information and how to do this. I’m definitely needing mine done pronto. Cheers. 👌🏻👌🏻😎

Great informative video, mine hasn’t been done for 60k so it’s desperate! I was also looking for the ‘doughnut’ coupling but that’s a different issue. Great work!

Is is the same AWD system as in the Mini Paceman ALL4 ?

Great video, very informative and clear.

A great video Andrew 👍

What’s the servicing for at 2017 diesel Quattro A6

Good job 👍

Great video keep up the fantastic service 👌👌👌

Very good video 👍👍👍👍

Discount code does not work

Had to get rid of my mk3 for a broken halded unit. 2300 they quoted.
