Tigger73's 125TSI Tiguan Build Thread

[tigger73]

Nice ! Looking forward for Dyno plots. Would be nice to see where actually intercooler helping in the power band. I think it should be mostly top end. Is it possible to get an acceleration log with Gtech pro? If you have these logs you can create a nice acceleration plot comparing before and after

Is this what you're talking about?




Not sure how to connect up and download data...may have to talk to AdamD who loaned me the Gtech

Yes If you look carefully last 10km/h jump has taken more than 1 sec. (90 km/h to 100 km/h) Could be due to that gear change from 2 to 3. Just think about if car accelerate same pattern it did to 90km/h and all the way to 100 km/h .. hehe could be easily a 4 sec car.

Nice to see you got your performance Haldex

I think I'd need to change the gearbox/ratios to make it into a 4sec car. Yes it's the change from 2nd to 3rd that slows the forward progress at around 85-90km/hr. Unfortunately I can't get to 100km/hr in second gear so need to shift again and as you say it doesn't ever recover the acceleration. The gear change combined with the increased wind resistance is what slows it down.

Hope to get it fitted on the weekend. Any tips for the install?

I am just wandering could a increase rev limiter can keep the car in second gear until it hits 100 km/h. On second thought it may need about 10% increase so about 7500 RPM red line? may not be feasible with our cars.

It should be easy enough. Just two bolts to unscrew and two connectors to unplug. One connector connect the module to CAN bus/ECU and other smaller connector connected to Haldex pump.

One connector is bitch to unplug (smaller one) so I first removed the two bolts from haldex unit and took the controller off from solenoid and then removed the connector. Also top bolt is hard to access (have some fun with a short allen key ) I used a very small mini ratchet I bought just for the purpose for the second time removal and install !

Another thing is solenoid is stuck in there( it will not come out with the controller) and hard to pull out by hand. I used vice grip to pull it out.( but be careful not to damage the solenoid body or connector) When you pulled out the old solenoid haldex oil will come out so be prepared to put the new one ASAP.

Good luck with the install, looking forward for a nice review.

Here is a nice study material to get better understanding of Haldex in Tiguan

Yes increase rev limit would probably do it but I'm not chasing numbers that badly that I'd want to destroy the engine

Thanks for that - nice study guide

Did you do yours on a hoist or on jack stands? I have heard people put on jack stands and tip the car so less/minimal oil comes out.

I've got the install guide which came with the product and it looks simple enough but it really doesn't say that much about how best to go about it.

Also did you replace your Haldex oil at the same time?

Second time removal???? Was that when you busted things?

Yes I used jack stands. You only have to lift one wheel ( rear passenger side). But if you can put the car on a hoist would make the job much easier


Yeah I change my Haldex oil same time actually I did it twice haha .. first time when my diff got damaged and the second time when installing my HPA Haldex.
