I see in the brochure for the latest Q5 that the Nose Weight has increased from 80kg to 100kg.

When I asked about why the NW was so low 2 years ago I never got a straight answer from Audi. The factory fit tow bar is made by Westfalia. All the tow bars they sell were rated at 100kg two years ago. But Audi applied a 80kg limit............ When I asked back then I explained about Westfalia's limit but it made no difference and I've had a struggle since staying below the limit.

Well I asked the question twice today at Audi UK and I also asked could I change my factory fit tow bar and get a new one that could take 100kg?

The first response - "was that the tow bar hasn't changed so fitting a new one will make no difference. Its because the kerb weight has changed that they have been able to increase the limit".

So a little research and I find that yes the kerb weight has changed.........its gone down to improve fuel ecconomy.

So if I have a lighter car I can have more weight balanced on top of the tow ball? What a load of rubbish it's the weight at the front of the car that balances what is on the back. Being lighter doesn't mean more weight if anything it should be a lower NW. I'm only towing at 70% of my cars capability so that's not a factor either.

Second response from a young lady who probably didn't know what NW was - "the systems have changed since you bought yours and that's why you cant have 100kg NW".

Two years ago I suspected that Audi had underrated the NW and I think the fact that the tow bar hasn't changed verifies that now. But I'd quite like a 100kg sticker to reassure me.

So I've emailed the Head of Audi UK to see if I can get an educated answer from someone.............As I type I've just had a call from Audi UK Executive!!! More to folllow tomorrow.

Anyone got any knowledge

It is interesting written that a 100 kg load includes cross bars.

I wonder what kind of response will give you

Audi does not recommend the use of other base carrier due to this:

Update is that there is a new factory fit tow bar assembly being fitted to the new Q5 which has a NW limit of 100Kg unlike ours which is 80Kg.

I am told that I can have this fitted to our car to replace the current one. Just waiting for the part number and the cost now to see if this is achievable.

No Spijun, that's the roof rack. I'm talking about the swivel tow bar.

Got the two answers I was hoping for............ Yes there is a new specification swivel tow bar with a 100Kg nose weight limit. Yes it can be put on my car in place of the one I've got.

Part number for the new one is 8R0800495D. Cost is £949.75 incl vat. Plus fitting cost on top of that.

Yes I am having it fitted as it will give me a safer and nicer tow. I will then aim to tow at 85-90Kg instead of my current 75-80Kg and still have 10Kg of a safety margin to allow for an inaccurate NW gauge.

Anyone got a handbook handy for MY11 models circa 2010/2011? My car is still being fixed.

Want to ask if there is anything in the manufacturers data, which is near the back in the Handbook, that states what the maximum Nose Weight for the car is?

Trying to work out if Type Approval prevents me from changing the tow bar?

Someone has told me that because a handbook is specific to the car for Type Approval purposes and that if nose weight is specifically stated as being 80kg in the Handbook then you cannot exceed that unless the Handbook is reissued.

So do Audi include that in the Handbook or do they just put a sticker on the car?

I'm hoping it is just the sticker and that can just be changed by Audi?

Well looks like its not financially viable after all. I can legally change the tow bar but because of the Type Approval limit set on the car at 80kg I can not legally use the extra capacity.

Which would be a major problem if stopped by VOSA and/or the Police.

So this idea is dead in the water.

I have asked Audi UK to clarify. I'm not expecting good news!

All being fair if your trailer can take the load you require to carry, your axle load limit is not exceeded and you have an issue with noise weight, I am not sure of the cargo/load you are carrying which cannot be moved to alter the noise weight you may have to look at trailer design. As you are aware of is axle spacing, wheel/tyre size and length of drawbar comes into it also, if a double axle trailer is the axles too far centered to the rear. I always liked a trailer slightly heavier on the drawbar to prevent rocking/snaking.
As per the 2011 and 2012 specification guide the unladen weight and gross weight has not changed, towing capacity is the same except for the SQ5, the only difference I think of is chassis design for the tow bar fixing is stronger. The weight of the engine will not affect this or the noise weight would change between the petrol and diesel engines.
You could even look at wheel design, brakes anything to do with weight, again max gross vehicle weight plus trailer @2400KG will give a train weight of 4430KG, there is no specification regarding gradient with max GVW, towing a trailer at MGVTW is better than unladen plus driver plus max trailer weight.
As you mentioned before see what Audi come back

You are correct Dieseldoug. I can balance the NW by moving the load in our caravan. I had a problem with NW and our last caravan caused by the design of it being NW heavy, which forced me to carry LPG bottles in the car. The manufacturer didn't advertise that fact then.

Just got rid of it for a new caravan which has a MRO NW of 75kg and so the problem is solved as I can balance it easily at 80 kg as the LPG storage is now directly over the caravan axle.

But I would prefer to tow with a slightly heavier NW. So if this new tow bar had worked it would have been a nice to have feature with a safer margin for a potential inaccurate NW gauge.

Tow car match says I'm towing at 78% and I have a perfect match. So all is not doom and gloom as it was cheaper to change the caravan than change the car.

Okay never knew it was a caravan, I had the same issue with single axle van at 21ft plus drawbar overall length 24ft on the large side for single axle, to keep what i wanted and the NW slightly heavy I had to shift things just rear of the axle to balance the gas bottles and what was in the front lockers. I run double axle trailers when required again you can shift stuff easy there, they were designed for my series 111 land rover and discovery, not used so much now.

Audi are currently still saying I can just change the tow bar and therefore increase the NW. As they say the new tow bar is designed and type approved for the Q5?
But i have a niggling doubt in my head that they haven't considered that the car is also independantly type approved too. So the question is whether the NW is one of the Type Approval figures or not? If it is.......as i suspect it is.............then yes I can change the tow bar but I still can't exceed 80kg. In which case it would be a waste of £1300 - 1500 imho.

So I've queried it again.......But i'm being ignored now. So I assume they're probably not impressed that I don't trust the say so of the Specialist Parts Technician saying "it should be ok". But it's not him or her who could be in the dock if they've got it wrong given that VOSA do spot checks on caravans on the motorways every year. I've asked that they get the Audi Homologation Dept to verify yes or no.

Strangely Audi have not put the NW figure in the Handbook with the permissable weights under technical specifications of the car. Those weights are set in stone.

I've also contacted the DFT for their advice and await a reply sometime in the New Year.

So I just don't know...........
