Folks:
With my observations of a lot of rumors, guessing, assumptions and observed failures, I am starting a new thread on this VW supplied Eyelet Bolt for Vehicle Recovery...

First off, I am going to say, I am not an expert. The claims and opinions I post on this forum and in this thread, are strictly opinions and research based on my own personal experience with the topic over the last 30 years of motorsport involvement. I will claim first, that anyone using the Eyelet Bolt as a recovery (winch point, tow and/or snap strap) should *always* refer to the owners manual of their vehicle, and those guidelines should *always* be followed to the letter. I will share my opinion and research only in an effort to generate discussion, and hopefully reach a consensus on the use of the factory supplied eyelet bolt as a recovery point for winch, tow, and/or snap-strap use.

I have experienced first-hand several comprehensive failures of that eyelet bolt design and its associated mounting point. As the Safety Steward for many vw/Audi/Porsche driving events in the last 25year, I have performed almost 1000 vehicle recoveries, the majority of them with either a 17500lb (ARB) or 24500lb (ARB) recovery strap. I am an offroad/rally/rallycross enthusiast, and have performed a wide variety of recoveries with both a winch and/or recovery strap. Again, I am no expert, only a seasoned Safety Steward and self-ascribed recovery specialist by count and experience.

Ok, with all that disclaiming, let's cut to the chase. First, let's look at the owners manual in my 2007 Touareg v10tdi for the use of that eyelet bolt inserted into the bumper. Verbatum page 105 Booklet 3.3 Tips and Advice:

VOLKSWAGEN DOCUMENT
"Do not pull too hard with the towing vehicle, and avoid jerking the tow-rope. When towing on unpaved road, there is always a risk of overloading and damaging the attachment points."

EU REQUIREMENTS FOR TOWING DEVICES - INCLUDING EYELET BOLT (ECE M1 1005 M1 Regulation)
Requirements for towing devices
1. SPECIFIC REQUIREMENTS
1.1. Minimum number of devices.
1.1.1. All motor vehicles must have a towing device fitted at the front.
1.1.2. Vehicles in category M 1 , as defined in Directive 2007/46/EC Part A of Annex II, except for those vehicles not suitable for towing any load, must also be fitted with a towing device at the rear.
1.1.3. A rear towing device may be substituted by a mechanical coupling device, as defined in UN-ECE Regulation No 55 ( 1 ), provided that the requirements of paragraph 1.2.1. are met. (Comment insert: I looked up ECE Reg 55, this means the trailer receiver can be substituded for the eyelet if it pases the 1.2.1 test)
1.2. Load and stability
1.2.1. Each towing device fitted to the vehicle must be able to withstand a tractive and compressive static force equivalent to at least half the technically permissible maximum laden mass of the vehicle. (Comment insert: Treg v10tdi = 7055lb/2 = 3500lb My understanding from the documents, this is a straight line pull test in the same vertical and horizontal plane as the factory mount)
2. TEST PROCEDURE
2.1. Both tractive and compressive test loads are applied on each separate towing device fitted to the vehicle.
2.2. The test loads shall be applied in horizontal longitudinal direction, in relation to the vehicle.EN L 291/42 Official Journal of the European Union 9.11.2010

------------------------
CONCLUSION/OPINION

My non professional opinion without knowing the actual test results from the Touareg or any other VAG model:
Until someone can track down the actual EN L 291/42 application from VAG to the ECE that states otherwise, my opinion is we Touareg owners should only consider that eyelet tow bolt to withstand the maximum force to the requirement in the ECE M1 1.2.1 test only. This is defined for my US 'as equipped' specificaiton Touareg, as half the permissible GVW of 7055lbs/3200kg = 3527lbs/1600kg of constant tow force (winch/tow rope).

Again, this is just my research and conclusion based on the documents required for all M1 passenger vehicles to meet ECE approval. Until someone at ECE/VAG can supply the EN L 291/42 application documenting 12.3.1 (front eyelet mount) and 12.3.2 (rear eyelet mount) test results, assuming any load higher than the ECE specification is only an assumption.

Cheers and be safe folks

Wow!

This seems to be a new trend on the forum.... people with real experience posting THEIR experiences.

Thanks, maybe those that repost without insight can begin to understand...

Hi Sumotoy


I have taken what you have said onboard. I have a 2017 v8 TDI and have contacted 4 4wd places here in Australia to have a front recovery point fitted. I have been met with blank stares and told there are no products available. An example of a response is this..


"
We have done a bit of research due to the lack of pre fab points. Unfortunately we wouldn't be able to help as there hasn't been an area on the chassis to mount them due to lack of strength to meet Australian standards. Public liability would become a big issue. ARB also won't be making them due to this issue.


Sorry we can't be of assistance on this but we can't risk any product failure."


Do you, or does anyone here, have an idea as to how to fit rated recovery points to this vehicle? Pics would be great!


Cheers
Brian

A lot of liability in all that nowadays, with airbags and crash zones etc, and it doesn't help it is not a frame chassis. I don't use my treg for more than light offroad, so the only thing I could think of is mounting a frame that uses the subframe bolts in front, and has the recovery gear attached to that.

In lieu of that, the only real answer is to always use the rear tow receiver. That may not always be practical, but I just don't see any other way. I'm also not convinced the safety standard I listed means that two eyelets with a harness, means you double the pulling capacity. You are only spreading the load, but the limit doesn't really change with that standard.

If you do figure it out, please post. A lot of lucky Treg owners out there using those front eyelets when they really shouldn't be.

Cheers

Subbed!

Great topic. I interpret the literature the same overall as you Scott.

My only conflict may be with using the dual hooks in the front to spread the load to ~7000lbs (3500 per eyelet). It would be reasonable to assume the two hook/eyelet would be feasible in the rear up to the towing rating of 7716lbs AND which equals what you could snatch with a tow hitch mounted for recovery per VW. So really the question is the capacity of the Front bumper assembly in relation to the rear for a snatch rating. Which translates to IDK for the Front...

Topline, I have been thinking a bit about adding some front hooks not because I need them but because I think it would be interesting (and I want to do some off roading). I have also considered a Winch mount.


What exactly are you looking for?


I don't see any reason mount points couldn't be added. I've been thinking about adding some over top of the stock threaded hole and using a dremel/hotknife to cut slots int he bumper to put them (similar to what Jeep owners have).


In all honesty I'm not sure why it couldn't be done. The question to me is one of distributing the load properly along the structure. Looking at the sub frame that I took off when I put my Hitch on they use about a 3/4" diameter weld nut to thread the recovery hooks into. The steel in the bumper bracket (on the rear) is maybe .040" thick but stamped.



As I mentioned I have been thinking about creating a front bumper reinforcement that would allow a winch and recovery hooks.


What sort of use would you put one under? What would you need it to do?

Hi NTDI


As the 4wd clubs here in Perth usually insist on 'rated recovery points' being fitted front and rear in order to join their club drives, I am exploring fitting a point to the front somewhere. I already have 2 VW screw in points and a bridle for the front. It would mainly be used for a snatch strap type recovery.



A 'plug and play' winch mount would also be very useful.



Cheers
Brian

Hi NTDI


I am not a technical bloke, not a mechanic or fabricator. I need to rely on the expertise of others. I guess the load would be 2 times the total weight of the vehicle. I am unsure of the force required to snatch a Touareg out of the sand on a soft beach. Most of the commercial recovery points are rated to 4500kg/10000 lb.



Thanks for the links!



Cheers
Brian


Topline, not too sure you understood what I was asking. How much load do the mounts need to handle?


Have you see these or these ?


I may build a set for my T3

I posed this question a little while ago too. I ended up buying a second towing eye for the front on my 23 V8tdi R-Line. I most certainly wouldn't be snatching with those though. It's a shame we haven't been able to come up with a solution. The only other thing I have been thinking about is a couple of these which turns the wheels into winches.

I guess my question is how much is a solution worth?


I only had one tow eye when I bought my Touareg used. I bought a second one because there was a slot for it. In the US tow hooks aren't required. However are a nice idea.


I could probably fabricate a plate to give better tow hook points. and possibly a winch. No reason not to mount some clevise hook points. It would take a little engineering but it could most likely be done. I'd just have to take my front bumper off and get started....

The Porsche Cayenne Transsyberia had a removable front winch. I assume that the design would be the same?
Or something like this:

Interesting topic. The old school way is to definitely have big chunky red coloured rated recovery points, not only to ensure maximum safety but appease the old school types and some clubs.
Another distinguished, conspicuous sign of hard core offroader vs a softie perhaps ?
Reminds me of the live axle debate.

Jokes aside, I have been using the eyelets individually and with bridle at times over the last 15yrs with no problems.
I have never heard or seen an eylet recovery point fail so far.
I recall trawling through engineering sites to check strength and durability of welded vs screw/bolted applications to learn about atomic fusion of materials and load spreading through bolt threads.
At the end I am comfortable with the eyelets.
A deep bog in sand can put immense load on recovery gear when snatching, but then you make it easy by digging out as much and throwing your max trax under.
But please if anyone has any video or data on any eyelet failing during recovery in the last 20-30 or 50 plus years then please share.

Topline that is my logic as well. I am using a bridle and two two points with a rated snatch strap. I am also using two soft shackles. Nylon ++ load rating through the eyelets plus a bag over the snatch strap to stop whiplash.

I understand there a limits to my understanding of load but that is the best I can do at present. There is no other information and what was given in the original thread starter suggests I am ok. Two tow points is 3200 kgs. I am willing to be corrected!

Interesting discussion... I'll add in my 2c

I'll just premise this post with a very short background in that I have designed a few hoists and other lifting equipment in my line of work.
I will provide a few observations around loads and safety factors of lifting/rigging equipment.


In general if an item normally used for lifting is then used in a horizontal application (hoist vs winch - disregarding other safety features required) or non-lifting application (lifting vs lashing) the safety factor is halved (capacity doubled)

The Touareg Expedition winch had a capacity of 9500 lbs (4300kg)
Hoist ropes typically have a 4:1 safety factor (in a winch application that would be reduced to 2:1) so the mounting of the winch should be capable of supporting a minimum 8600kg.
The Expedition winch is mounted to the car via the same 8x bolts as the bumper reinforcing.
The four Grade8.8 M10 mounting bolts on the winch have a shearing load of approx 2650kg each through the thread. (Total 10,600kg)

I think it would be fair to assume that the chassis would be good for at least 8500kg.


The VW tow eye is an M18 left hand thread.
An M16 high grade bolted lifting eye has a straight pull working load of 4t with a 4:1 safety factor.
So the thread in the bumper reinforcing should be up to the task.

Except the bending moment of office tee loads needs to be considered. On a bolted connection like the Euler requires a sufficient tension to load the washer area with enough compressive load to cover the bending moment at the interface point.

Thus the off axis loading is a concern.

The real issue is the design of the bumper bracket and it’s attach point in off axis loadings.

Definitely side loads need to be considered. I'll bet there's notes in every ARB recovery point packaging that mention side loading considerations.

The bolted lift point I mentioned above drops to 1.5t lifting WLL at right angles. Still 3t capacity in pulling application. (6t break load)
