Costs soon mount up at dealers so best going elsewhere.


100% agree, but was super difficult while Covid19!

But luckly been able to find a decent indie garage that specialise in ONLY BMW's 8 miles from who will collect the car next Tuesday and touch wood deal with it all in a professional ...

Update:

After phone calls with the main dealer I have collected the car and will be continuing the fix finding with a local top notch indie garage (Baymow) that are now back open, unfortunately they can't collect my car until next Tuesday.

The main dealer wanted to spend more time investigating ...

Glow plug controller may well be faulty but as others have said its a very common issue and I seriously doubt it has anything to do with your battery drain ,changing it without the plugs seems a waste of time as they will almost certainly be faulty too . After its fitted Id expect them to be ...

I understand your scepticism and after years of having difficult conversations, you are absolutely right to be. Part of the issue is they believe the code reader regardless. Too many BMW (and other) ‘technicians’ cannot work from first principles. Code readers can be wrong although it’s rare as it ...

Glow plug control on a car that old is very common and is frequently caused by failing glowplugs. It should be a relatively simple job but is fiddly on the E70 because of where the controller is located below the inlet manifold meaning disassembly required to get to it. The BERU made module is ...

Update:

After 1 hour at the main dealer for diagnostics they see a fault code coming up circulating around the GLOW PLUG CONTROL MODULE, however they need to go in to a 2nd hour to clarify. On Monday morning they will give me a costing on the control module, I get very very nervous IF in fact the ...

3 days and live terminal reconnected under bonnet and ZERO drain!

Looks like the car has an untraceable gremlin which has a mind of it's own. Slightly annoying as I've got it booked into the main dealer tomorrow for a diagnostics check, I only hope that even though the drain issue that seems to ...

As already said, the test cables were probably not rated for the 240A alternator output that these cars generate. It’s current that cooks cables, not voltage. If the test wires were thinner than the cable feeding the alternator, then that’s why they cooked! There’s a reason for the 12mm diameter ...

With the IBS being in the main power charging circuitry which also includes the alternator, there may well be a possibility. I’m not discounting the alternator as a potential cause of this - though I’m puzzled as to which bit precisely.

These cars can be a nightmare to diagnose random ...

The IBS is part of the connections at the battery end......

Note the comment about error codes. Have you had the fault code log read to see if anything is logged ...

I'll just go off piste :D ...Does your vehicle have the IBS (intelligent battery sensor) , if so it is located to the negative lead on the battery, normally on the back of the clamp, unplug the connector...Ive just had this happen, so I unplugged it and no more drain...been unplugged for 2 ...

Realoem will give you an indication of price in dollars. You’ll need the last 7 of your VIN (put in serial number box) to pull up the right car. There are two alternator versions dependant upon what options you have. 180A or 230A are fitted. If you have 4-zone climate then you need the higher ...

48 hours since disconnecting to positive lead from under the bonnet which takes out the alternator, car unlocks fine with fobs, interior lights, hazards all working as they should, no dimming. So far so good, not willing to try and reconnect to start yet though, want to leave it another 36-48 hours ...

Hi guys,

Bit of advice if I may.

Couple of weeks ago my X5 2011 (Non comfort access) decided to have a totally flat battery. Hadn't driven it for maybe 2-3 days, never had an issue before. Pressed the fob, nothing happened, tried the spare fob, same result. Got in the car via the emergency key ...
