E60 M5 weekend use only ...
Discussion
To be honest, thats as often as i use mine and the same annual mileage (only done 10k in 24 months). I have no issue leaving my car undriven for 2 weeks so long as i move the car 12 inches forward or back once every 3 or 4 days to stop the tyres getting flat spots. If you plan on leaving the car sat longer (3 weeks or more) then a trickle charger may be a good shout but 2 weeks is ok so long as the battery is full.
Also, if the car is left for a bit make sure you let it warm through the cold start process before driving off.

By cold start I assume you mean when the revs drop and the diesel sound dies down Also, if the car is left for a bit make sure you let it warm through the cold start process before driving off.
Takes a while to get the rpm redline at its max so hope you don't mean that!Not sure about the tyres but happy to be shown otherwise ... have a foot or so to play with where it is parked

What cold start process would you recommend :-) ?
Do the tyres really flat spot that easily just from being still ?
No process exactly, i just let the cold start idle settle (about 45 to 60 seconds depending on temp) before i drive off. Reduces that kangaroo effect you get when cold. Do the tyres really flat spot that easily just from being still ?
My tyres do show signs of flat spotting after a week or so left static. Only shows itself as a vibration around 70mph but disappears after a few minutes of driving once the tyres gain some temp. Ive had this feeling on all my performance cars, on different sets of tyres too. I think it has something to do with the excessively heavy nose hanging over soft rubber. If i drive it more regularly i dont get the vibration (felt through steering wheel).

3-4 days? Never heard anything like that before. What happens when people go on holiday for 2 weeks do they hire people to come round and drive forward and back?Also, if the car is left for a bit make sure you let it warm through the cold start process before driving off.
I go away weeks at a time on business and leave for up to 2 weeks and have never had any issues at all!

Mine is left out in the rain and sat idle for week or two and I reckon it's not ideal. I've now got electric boot release opening itself and potential parasitic drain problems. BMW are absolutely s
te at Electrics!!!!
That, i can diagnose exactly! The loom that runs in the hinges of the tailgate breaks over time causing the wiring to short against the metalwork. Needs one or all the looms replaced or rewired. I had all mine replaced under warranty in Jan 2011.te at Electrics!!!!.edit. There are 4 looms in the tailgate and they run 2 per hinge.
As for the leaving it sat thing, im not saying you MUST move it every 3 or 4 days. All im saying is it helps stop the tyres get flat spots. Some people never notice it as they rarely get on the motorway or above 60mph where they live. My street, afte a half mile runs straight out onto the dual carriageway and any flat spots in the tyres show up when i hit motorway speeds. Had i had a few miles of 30mph to run before the national road i may never notice the flat spots, but they are there. Had it on Pirellis, Mich's and even on the harder Vreds.

OK Eddie, yes I have done some research and there are two potential culprits.edit. There are 4 looms in the tailgate and they run 2 per hinge.

1) Boot hatch glass switch (sealed unit) which is a common problem on the E61 LCI's. It is a 30 quid part and my specialist is getting one in and changing it. I also had the clock and trip computer reset on me pointing to battery drain issue related and lots of other threads on other forums point to the small switch being the culprit. Wet weather recently could have got in and shorted
2) The loom you describe and I hope not as that will be alot mote and sod's law won't be covered on the named component warranty I have.
Also should add that I had the issue with the remote key not working too but that could be unrelated or maybe related to the loom again!!!
I had nothing but issues on the X5 with water ingress affecting electrics and I wish BMW would sort it out, to put the modules in the floor of the boot is just asking for fecking trouble!

The tailgate switch is a common culprit but it rarely shows up messages or causes problems outside the tailgate area. Best thing to do is to change the switch, hope for the best, and then if nothing improves push for a warranty fix on the wiring. BMW price was £1700 for the looms last year but i reckon a good indy could repair instead of replace for a good bit less.

T'is a good thing BMW didnt use a lot of the electrics off the X5 of the time to build the M5 then..........., lol, oh yes they did.

Be interesting to see if I have shot myself for not going fully comp lol! Sods law will dictate it will be the loom and it won't be covered!The tailgate switch is a common culprit but it rarely shows up messages or causes problems outside the tailgate area.

The other thing moving it 12 inches every 3-4 days would it not damage the engine as the engine oil is not at the optimum temperature for protection ?Also, if the car is left for a bit make sure you let it warm through the cold start process before driving off.
And doing this long term would damage it .... I think longest you can leave without driving is 2 weeks or 4 max but battery would have to be fully charged ...

Parasitic drain problems - could be the door handleste at Electrics!!!!Boot opening itself - if it's just the glass, then it's probably the switch
