Tow Bar Fitting on Altea

Temporary Noble

Guest
I thought I'd briefly share my tow bar fitting experience:

I went for a Bosal Swan Neck from Towequipe in Manchester. This can be used as removable in that the swan neck is only held on with two bolts, removing it just leaves a couple of plates below the bumper (see photo).

To fit the bar, the bumper has to come off, lights out first, then work around the edge removing ll the screws - 5 in each wheel arch, 2 revealed by each light cluster, lower lip underneath, then just pulls off towards the back of the car.

The tow bar bolts on in place of the crash bar, no drilling required, very simple.

I've mounted the electrics socket on the bumper, with a little metal bracket.

WIRING

There's lots of debate about this on here and other forums. I have used a smart relay from ebay, which can detect the difference between sidelights and brake lights, which are supplied by a single wire.

There's plenty of space at the near side to accommodate the relay, and the loom is over there for most of the wires. I've used the often dissed scotch blocks to tap into the loom, as I have done loads of times on other cars.

Near Side:

Off side:

The smart relay means you only need to tap in to the sidelights and brakes at one side - in fact one connection for both, and it figures it out for you. For the fog light I couldn't get a detectable signal without going all the way to the feed into the bulb holder, and running a wire all the way back across, but works that way.

SO, it is possible to fit and wire up yourself, using inexpensive components. My set up will not inform the ECU that I am towing. This may be a concern for you, in which case you need the trailer module and all the associated wiring. As I only tow occasionally, and locally, this would seem to be unnecessary to me. There's also the use for luggage carrying to consider, as I have a Thule luggage rack that we use for the annual Le Mans camping trip - but it's not a trailer and doesn't need to change the stability programme. To me, this negates the need for the ECU to be aware of a trailer, as there is not trailer even though the electrics are used.

Hope this helps...

Towbar electrics.

Thanks for posting the info and photos.

I've been looking for a socket or terminal block to connect to but it seems that the Altea MPV has neither. Hopefully I'll be able to finish the wiring this weekend now. :)

Is it difficult to remove the trim to get access, or more particularly does it go back OK?

I used a towbar from towbars4cars which I got on EBAY and it's very good and solid.

Easy enough, just a faff! All goes back ok, fixings are all screws if I remember rightly, not break-able clips!

Thanks again, wasn't expecting screws.
Need to get the car out, next time it's fine and look a bit harder for the fixings then.

Removing the trim fixings was easy enough when I came to look at it.

The wiring kit that came with my towbar wasn't model specific so it didn't have colour codes for the wiring loom, only the 7 pin socket.

Will test out the wiring with a multimeter tomorrow and report back with the wire colours in the loom when everything is working. Only hope that the wires for the offside lamps are in the looms on the nearside.

It's a bit misleading though when the wiring looms are on different sides depending on which model of Altea you have and some have plug and socket connectors and some don't.

So long as you have a smart relay should't be too tricky. I had to go to off side for fog light. Didn't note the colours, but you might be able to see in the pics?

I tried to find out the colours by unplugging the plug to the rear lamp cluster and measuring the voltage but the sensor circuit switched off the power to the plug.
Had to revert to the old method of sticking a needle into the cables and testing for 12 Volts. Not really recommended but when you can't get the information any other way.......
Got it all sorted but the 5Amp fuse for the stop light blew with the extra load, now 7Amps.
Haven't identified the fuse yet as there's no fuse numbering and a previous owner removed the extraction tool which didn't help. It's supposed to be No.23 but where that is is anyone's guess.

It's multiplexed, be careful! Same wire (& bulb filament) does stop & tail...

Don't know whether the multiplexing or the lamp sensing is causing me problems but the 'dead bulb' indicator is lit.

More investigation is necessary before I get it sussed.

Bought a workshop manual on 3 CDs but the installation is very messy and longwinded as it covers all Seat models from '94 on. When you finally get to the end you find that it won't re- install over an previously abandoned attempt, so I just gave up on it.

Have you any recommendations re a sensible workshop manual?

Thanks,

Ron

Hi,
What make of smart relay did you get and did it come from Discount Towing Supplies or elsewhere?
Thanks,
Ron

It must have come from Tow Equipe, don't know the make, just cheap though, nothing special.

Does anyone know if a normal flange towbar will interfere with the parking sensors? The only reference I can find is about detachable towbars. I prefer a fixed flange one because I park in a tight space and some of the people around seem to lack parking skills so it gives me a little bit of protection from them too :)

It doesn't until you fit a protection plate.

I cut my plate down to about 8" to give clearance for the sensors.

The sensors don't have a very wide viewing angle so you should be ok.
