Re: Tow Bar
Does you car have a canbus electrical system? If yes, and you're not confident about wiring stuff yourself, get someone who knows what they're doing to wire it as they can sometimes be a bit weird unless the correct interfaces are used. Some are quite straightforward - many aren't.
Not every car has fitting holes opened up out of the factory - plenty have markers on the frame where drilling needs to be done, some removable towbars require a cut to the rear valance too.

Re: Tow Bar
If I remember correctly the E90 BMW requires the bumper to be removed to fit the bar. There is a small cut involved in the undertray to allow the neck to come through. The detachable (last one we fitted at work was a PCT) is nearly invisible when removed with only the breakaway cable lug visible. The socket plate flips down when needed. A seven way bypass relay is needed because of the canbus system on the vehicle. With the right tester these are not hard to do and the 12v feed can be taken from the battery in the boot. Just make sure any bar you get covers the M-Sport if yours is one as the bumpers are different at the bottom and not all bars fit. I think you remove the impact beam from the back the fit the bar in it's place.

Re: Tow Bar
Not sure if it helps, but when we got hold of our local Indespension depot, they quoted us 25% under the nearest asking price from so called "specialists".
Although not removable, fully fitted with electrics to our C4 was around 100 notes.

Re: Tow Bar
I may be wrong but dont you require b+e to tow a trailer with a car?
I think the rules changed about the time you got your licence. I know for sure that i need to do a seperate test if i want to pull a trailer. I can also only drive vehicles up to 3500kg i think. Good luck |

Re: Tow Bar
If passed test after 1st Jan 1997 - you can tow a trailer trailer up to 750kg laiden with a Maximum towing weight including the car of no more than 4,250kg.
Or, a trailer over 750kg as long as it is no more than the unladen weight of the vehicle and with a combined weight of less than 3,500kg. Taken from gov.uk

Re: Tow Bar
Thanks for the advice fellas, think I'm going to carry on riding the bike to the few track days I doe guy said the bumper had to come off and cuts had to be made so I suppose the price is pretty good considering the work involved.
Better see if I can afford a trailer first! |

Re: Tow Bar
I was a bit meh about cutting my bumper but you can't see it unless you get under the car, I still did mine nice a tight with an air r/saw and it was neat. My dad has a 3 series but he bought the mega expensive removable one and his still needed to be cut. One advantage of it is with the bumper absorbers removed and replaced with a big **** off hefty steel 2 1/2 foot bracket that runs tight along the inside of the bumper, so if anyone goes up the back of you it will finish them off for sure.
I'm flogging my trailer soon as I'll getting a van in the next few weeks (hopefully) Last edited by Wideboy; 27-03-13 at 09:59 AM. |

Re: Tow Bar
Hi Lenny, most modern cars post 2005 will have an additional socket in the boot harness to attach towing electrics and buying a dedicated harness makes life easy (so they say) generally needed due to bulb failure and load, electronic warning systems.
There are several manufacturers of detachable tow hooks/bars and in general have different attachment positions and can vary as to whether the bumper needs cutting or not. I have fitted a number over the years and have found a local firm to me that advertises on Fleabay and they carry all of the major makes and have been exclusively selling towing equipment for many years look out for Tow Equipe not the cheapest but knowledgable.

Re: Tow Bar
I've fitted to an E36, an E46 and an E61. E36 had to be drilled, 46 & 61 no need to drill anything. For wiring in all 3 cases everything apart from the left hand indicator can be tapped into as the loom goes past the battery. You'll have to run a lead across the back bulkhead to pick up the left indicator. Check the colour at the light fitting, unravel the black ribbon, find the wire, confirm it with a pin and test meter and off you go. Live feed straight off the battery clamp, earth is easy to pick up on a bunch of brown wires that bolt to the bodywork by the battery.
Get a bypass relay that can deal with modulated lighting usually £15-£20. That way it'll deal with it if you've got the fancy multi-brightness brake lights. If you've not got fancy brake lights it'll still work and not get fussy when your lights soft-dim. I've never bothered with the canbus interfaces as they are much more expensive and require a BMW recode to work. In most cases you'll have to cut a slot in the underside of the bumper. This should only be visible if you are laying on the ground. None of mine have been visible at all once fitted. Don't forget to reconnect your reversing sensors when you put the bumper back on and ideally do it on a warm day then the twisty plastic things you have to twist to get the bumper off are much easier to move. Oh and put out a blanket to lay the bumper on unless you have a handy lawn.
