Horizon - interesting!  I've just had to replace the BMW fitted 13 pin socket that was installed when I got the car 10 years ago.  Issue was the left hand winker was out.  On inspection its a wonder anything worked because of extensive corrosion at each terminal caused by a leaking seal behind the socket - the dealership had actually run the two additional power leads in separately from the OEM wiring loom and had just put a hole in the rubber seal for them that, over time, let water in. Off from Durham on Thursday to the lakes so I hope the wind abates - have a safe journey tomorrow - if you're on the A1M between Durham and Darlington take car as it's notorious in the wind.  If on the A19 watch out on the Tees flyover, it's as bad.  Gan canny as they say in Northumberland!

B21playa, just a daft question - you did look in the little cubby next to the battery behind the stowed away rear seats for the ball - it's where they are kept!

As well as the handbook, there should be a plate on the B pillar inside the driver's door that gives all the different sizes and pressures.

The ratings apart from size are for load carrying - 107, 111 etc.  Because the 7 seater can carry all that extra load best advice is to stick with the weight ratings the manufacturer recommends. I know from experience that insurance loss adjusters look at the tyres fitted in the event of an incident, and perish the thought that children in the back seats might be hurt in an accident. Cutting corners with tyre costs is just not worth it!

I hope all goes well - the car grows on you!!

Just be careful about wheels and tyres - there is a load of threads and comments about them, especially the strong advice to use * marked tyres that are BMW approved.  Read them!!!! Remember too that the 7 seat option requires tyres to take the additional weight - 107 on the front and 111 on the rear. The front wheels are different size to the rears - currently mine has Goodyear 255x50x19 107 runflats on the front and 285x45x19 111 * runflats on the rear. The 7 seater does not have space for a spare wheel hence the value of runflats in case of a puncture.  My winter tyres are not runflats - couldn't get them at the time I needed them so they are Vredestein Wintrac extremes and I carry an electric pump and two cans of Holts Tyreweld (can be washed out after use) just in case.  Touch wood after 4 winters I've not needed them and I've done quite a few miles in the wilds of Durham!!!!

Hi,

I've not had any problems - touch wood - with the adaptive drive in 159,000 miles. Over the last 3 years I've had to replace both air bags and a front spring though.  Work done by an independent specialist at reasonable prices.

Hi,that's very disappointing news.  A replacement price will depend on the price of a replacement bar and ball.  A key question for Witter is will the ball assembly fit your existing towbar? If the design has changed you may not need replacement electrics but clearly the bumper etc will have to come off to replace the bar.  Only a specialist fitter will be able to advise.  My bar and electrics are BMW parts, made I believe by Wesphalia, and were fitted by the local BMW dealership when I bought the car 10 years ago - cost then was nearly £1200.  Sorry but I've no idea what specialist tow bar fitters will charge as that will depend on the price of the parts needed and the work they have to do.  Let us know how you get on...

Hello,

When you say "tucked the electrics up behind the bumper" do you mean the 13 pin socket is up there?  If so it's because they are often fitted to a swinging bracket - just rotate it firmly 90 deg anti-clockwise and it should click into place for use.  When finished, tuck it away again! If the wires have been cut then it's a job and a half to fit another socket!!! I guess you can see it's made by Jones - the BMW fitment and many after market ones like mine are Westphalia. Good luck with the quest for the ball - make sure the socket and the V shaped slots that locate it are clean because they are a tight and precise fit to prevent any movement.

Nehal X5 is absolutely right.  I have a 2007 3.0sd registered in 2008 that came with adaptive drive and self levelling air suspension with the third row seating.  If the car is up on a ramp you can easily see the electronically controlled rear shock absorbers of the adaptive drive system.  It can be stiffened using the sport mode switch behind the gear shift.  The air suspension is a separate device that does as it says - it keeps the car level and the headlights pointing properly to compensate for extra weight in the back.  I believe, but this needs verifying, that cars with factory fitted towbars also have rear air suspension. At the front shock absorbers and springs are based on McPherson strut design and is not an air suspension.

Hope this helps,

Graeme

Although it was registered in April 2008, mine is an August 2007 build E70 3.0d, not the SE, and the annual tax is now over £500.  The change came in October 2007 with a different engine and, at the time, "efficiency dynamics" being a main selling point as well as the tax being halved because the CO2 emissions dropped from 231g/km to below 225 - the magic cut-off point!! I don't know what the tax situation was with 3.5 and 4.0 M Sport variants. The tax difference is £5 a week which may make a difference reflected in the purchase price - though 9-10 year old cars will probably have a high mileage so seeing a service history is vital!

It has some  sport pack items fitted such as sports seats, M steering wheel, adaptive drive, shadow line trim and anthracite roof lining but sports suspension deletion.  19" wheels were standard.

For adaptive drive, the rear shock absorbers are electronically controlled by sensors that give increased damping to keep the car as level as possible during cornering.  It makes the ride noticeably better than in cars without it that roll on corners!

It's a 7 seater and thus came with air suspension which automatically levels the car.  It's easy to tell it's working because if xenon lights are fitted the car levels itself and the beams point where they should, compensating for the load in the rear or if a caravan is being towed. I believe if a factory fitted towbar is present (not an aftermarket BMW one) the same suspension is fitted even if not a 7 seater.

The adaptive drive and the self levelling air suspension operate independently of each other, are automatic and cannot be controlled by the driver, except that there is a sport setting switch behind the gear selector that makes the adaptive drive a little firmer - noticeable on fast twisty roads.  If you can get the car onto a ramp it's easy to see what rear suspension is fitted - the air bags and the electrical contol systems fastened to the shock absorbers - but not so easily seen unlss you crawl under the back!

As X5 Sport rightly points out you need the brochure for the model year of the car you're looking at because they kept changing the packages offered.  Mine has black roof rails, black wheel arches though the sport pack did not change their colour - that came later!!!  You should be able to get a print out of all the specifications, and extras fitted or deleted using the VIN number.

Hope this helps,

Graeme

No need for that Spandex! This is a gentleman's forum.

In January this year X5 sport wrote " I have seen (and used) advice that the circumference should be within 1.5% but haven’t yet worked out what that means in reality when compared against relative tread depth".

That circumference is approximately the difference between new and worn tyres. it is difficult to look at different makes of new tyres side by side and judge 5-6mm difference  by eye - and I spent a whole career making measurements to ensure best fit!

Hello,

It's just that the rolling circumference is the key measurement and I find it easier to check that accurately than stand tyres side by side and measure the diameter which, because it's about a third the circumference, is less easy to gauge!  If we're talking mm then....

Best wishes,

Graeme

I'd have thought for an accurate assessment they should be fitted and inflated to the pressures indicated either front and rear to low load or both to heavy load, and the circumference around the centre measured making sure the tape does not go into a groove!  Graeme

Mine is a 2007 E70 with third row seating and in turn the rear suspension is uprated.  In relation to your query, the wider rear tyres  have a higher load rating - 111 on mine compared to the fronts - 107. (Mine are 285 x 45 x 19 x111V on the rears and 255 x 50 x 19 x 107V on the fronts).  The reason - to handle the extra weight if all seven seats are used and there is luggage in the back as well.

Reversions such as you describe, or loss of memory on preset buttons, or loss of time on clock, or loss of data on the journey computers are often signs that the battery is struggling to cope.  Lots of start-stop journeys drain the battery quickly as many systems continue to use power for 15 mins after switch-off. It can take 20 mins or more motorway type driving to recharge it after a single start up. There is really only one cure - a new battery.  However, it's not a simple swap - the new one has to be coded to the car to reset everything including the charging rate by the smart alternator.  For similar reasons my 5 year old one was changed by BMW about 2 years ago with an identical replacement, fitted and coded for £148.  My local indy couldn't get an equivalent battery for less that £140!

The 7 seater has an uprated rear suspension designed to carry a greater load, as well as increased towing capacity.  Rear tyres are rated 111 and fronts 107 to carry the additional weight.  All part of the design I guess that no doubt BMW engineers worked out is necessary!
