There are some wheel nut removal tools that should do the job

Haynes do a manual for the 3 series which covers the Z3 as most of the mechanicals are the same

Maybe easier to strip down and repaint yourself...going to do that on mine as it seems to be suffering from the same malady

Worth checking the light clusters for corrosion...but as the indicators are working on the hazard switch then its doubtful that there is an issue with them as the hazards come from a different power source than the indicators....so yes you may be right with the footwell unit diagnosis

Hi Mark....welcome to the Forum

It sounds like one of two things....first one is that you have the wrong bulb(s) check that if the bulb holder has one or two contact points then the bulb should have the same amount also.

Secondly, if the earth connections are poor then this could also produce the same effect....try running an additional earth wire to the side of the bulb and see it that cures it.

Let us know how you get on with it

Cheers .  Trevor

let us know how it all goes and would love to see a piccy of it

If it works then its the cheapest route to go otherwise replacement is the only other option then

Hi Adam....welcome to the Forum

Fine looking car and practical as well...enjoy!

Good to have you onboard

Cheers .  Trevor

Top quality repair....shame it happened in the first place :-(

Maybe worth flushing out the engine oil with something like Wynns or Forte to clear out any carbon deposits and see if that resolves it.

Also, worth trying good quality fuel to see how that works.

Hi Steve...welcome to the Forum

The 635 is an awesome car and is generally quite reliable but a thorough inspection before buying backed up with a long warranty has to be the best way forward.

I would recommend an independent inspection company like Dekra  https://www.dekra-expert.co.uk/vehicle.inspections

It also helps to get any defects rectified prior to purchase or price reduced to compensate.

Let us know how you get on with the purchase

Hi Barry....welcome to the Forum

That's a difficult one....first thoughts are non-factory conversion and Cat D as well....maybe worth holding out for the right one?

Cheers,  Trevor

is it diesel?

A good remap (for economy and driveability) shouldn't compromise the durability and reliability of the engine....different story for remaps solely for performance gains (e.g. stage 1, 2, etc)

Hey Jude (sorry couldn't resist that)

I would opt for the 2.0 if you are going to use the estate for the purpose it is designed for (e.g. carrying loads) in which case the extra power should compensate to a better MPG overall.

Let us know what you think of it when you get to drive the 320 in comparison to the the 316 and 318.

Cheers,   Trevor

Its nice to know the speedo is reading fast so that when you go through a camera at least it will be the right side of the limit :-)

Enjoy it and always tempting to know what MPG  it will do it you go lightly on the throttle :-)

Could be that the engine has been on a regeneration cycle (if it has a diesel engine) and the temperature is increased for this cycle so has to cool down enough after switching off?

Hi Miguel and welcome to the Forum

I personally find the feature annoying although in a city with constant start-stop traffic it can be a blessing.

The feature can be switched off it annoys you so your choice really.

Let us know how you get on with it

Hi David....welcome to the Club

Quite possibly is it this one:  3.0 L M57/N57turbo I6

Keep us updated on how you are getting on with it and would love to see some piccys of it

Cheers,   Trevor

let us know how it goes...be nice to see if that resolves it

Would be interesting to see how readings differ between the speedo and actual GPS readings with the current wheels/tyres combination

Fame at last !

will look out for the video when it's released

Hi Lee

Is it a plastic or metal elbow?

I would assume that if it is secured with fasteners then it can be removed and replaced.

Let us know if you manage to source one and if not then we may be able to dig deeper

Cheers   Trevor

Hi Rob

It shouldn't make too much difference to the speedo reading as there is always a % fudge factor either way (you can always check it on an external sat nav) also if you are altering the profile of the tyres, as you say, there wouldn't be much if any of a difference in readings.
