I am really sorry and surprised to hear that you've not been happy with your Tiguan. As you are probably aware, we have used several over the years at the Tow Car Awards, and without exception, they have all aquitted themselves very well indeed (a Class winner on at least one occasion). They were all towing Swift caravans, which of course were ideally ballasted, but stabilisers had been removed. Some of the manoeuvres that are carried out at MIRA are verging on the extreme, and certainly not things that I would ever wish to repeat on a public road. I wonder wheter you've hit the nail on the head and it's a strange anomoly with your particular car and caravan aerodynamics?
Hi, thanks for your interest.
I have read about other Alutech owners commenting on poor stability (with cars other than Tiguans) so perhaps it is something to do with certain combinations.
I know that other people find such things tedious (as I would myself) but, briefly, I have been towing various car/caravan combinations since the 1980's - some better than others.
In 2008 we bought a Chevrolet Captiva (Antara) to pull our Geist. No ATC, but it was a joy to tour with it - stable and totally unremarkable (in a good way)
Then we decided to have a break from caravanning, so we sold the Captiva and bought a VW Touran. I had a single 7-pin tow bar fitted so that I could use a trailer to move garden rubbish, etc.
Then we bought the Olympus from a private seller, and went to collect it in the Touran. It was remarkably easy to pull it (despite being only 1600cc Tdi) and it felt *reasonably* stable considering that the Touran only had a 1500kg kerbweight. As it only had a 7 pin plug the ATC was not active either, but we towed it 150 miles home without trouble, and subsequently used it a couple of times loaded - again, not wonderful, but acceptable if one kept below 60mph.
Then came the Tiguan - 2014 4-Motion Match 140ps - which I assumed would be wonderful. We duly had a PTC bar fitted at their factory (using a Jaeger wiring kit that meant the VW trailer stability programme was enabled in addition to the Alko atc.
Hitched up for our first trip, pulled away from our house, made a sharp L/H turn - and, THUD! , a bang as if we'd run over something on the road. Stopped, checked, couldn't see anything wrong, so continued on our way.
It felt awful!, really unstable. Stopped a couple of times to check, but couldn't see anything obviously amiss. Only had to go 35 miles, so plodded on - at less than 50mph.
No more bangs or thuds until the return trip when there was another almighty 'thud', this time after a sharp R/H turn. Caravan was unstable all the way home.
I thought the towbar must be loose, so went back to PTC who checked it and announced they couldn't find anything wrong. Of course, they were hardly likely to tell me if they had!.
I also went to my supplying dealer, who humoured me by checking the car on a ramp - just in case it had arrived from Germany with a faulty suspension part - again, no problem found.
After that I became involved in a seemingly endless progression of attempted fixes! - had the van chassis and bearing checked, changed the AKS friction pads twice! (side pads & front/rear pads) replaced the supplied PTC towball with an official ALko version (just in case) checked and greased the overrun, even rewired the caravan 13 pin plug in case a bad connection was causing the ATC to enter the test cycle when driving.
Then I added Grayston donut assistors, checked and rechecked tyre pressure on the car & van - just about anything and everything I could think of.
Still it was highly unstable - I spent most of last summer fiddling about with the outfit - and couldn't face going any further than about 35 miles in it.
The closest I came to a reasonable tow (and it was only reasonable in comparison to the previous nightmare journeys) was by putting 55 psi in the Tiguan and increasing the caravan noseweight to over 130kg! Both values in excess of the maximums permitted.
I read a Caravan Talk thread relating to a clunking sound experienced by someone with a PTC flange towbar - which was only resolved after fitting a Westphalia. So off came our PTC bar, earlier this year, and on went a brand new Westphalia detachable.
Additionally, I came across a brand new Alko AKS3004 that would cost me less than £100 after selling my old one - so, becoming increasingly desperate to avoid a repetition of last year's nonsense, the new AKS went on as well.
Then came new Dunlop tyres (balanced) and some Tyron bands.
I hoped (prayed) that would have cured it , and took it to a weighbridge a couple of weeks ago to get a definitive weight figure with the van empty but including the motor mover & battery.
That weight was 1300kg (noseweight 80kg) - and the Tiguan has a kerbweight of 1650 kg (plus 2 occupants) so the car/van ratio was below 80%.
That should have produced a really stable tow - but not a bit of it!. It felt just as bad as before.
I know what a stable caravan feels like - and I know when one feels as if it's about to snake violently, which is how this combination feels (to a greater of lesser extent) no matter what is done to it.
So, yes, I hate the thing and wish I'd never heard of VW Tiguans! My main regret is that I foolishly rejected a chance to buy one of the very last 'old' X-Trails! instead of the Tiguan! I was blinded by techno-rubbish (self parking, and gadgets that I have never, and will nevr, use. In the light of the Tiguan towing woes I bitterly, bitterly, bitterly regret not getting that X-Trail!
Sorry if this seems a bit 'rantish' - but I'm seriously miffed about the whole experience.
