Morning Kieran Welcome to the Forum This is a new problem, I would start with the power supply where have you taken it from ? If you haven't already I would check a wiring diagram for both models to see where the power was arranged in the M4 and check whether that supply is available in the 140 model. Then check www.realoem.com to see if there are repair/replacement looms available. Your description sounds like a relay is tripping in the power feed Good luck with finding the issue let us know how yoy get on Dave

Morning Cid have you found the 2 screws underneath the very bottom middle of the door card under the storage bin? Once the screws are out then its working around with a trim removal tool to pop out the clips I started at the bottom you should be able to lift/lever the card upwards to release the top edge which is held by spring clips Check the internet for any useful videos that may help Good Luck Dave

Morning Rob A quick look at www.reaoem.com indicates the OEM battery would be standard 110ah but can be changed for 90 or 92ah AGM. Just remember your car has IBS so will need the battery registered to ensure correct charging Good Luck Dave

Morning Bruce Hope the Test Drive goes well and Welcome Back Dave

Morning Kelvin Welcome to the Forum Shipping could be a high cost as we tend to be mainly UK based, good information for our US mambers though Dave

Morning Jorgen Welcome to the Forum You can check on www.realoem.com put the last 7 digits of your Vin into the search box it will call up your model then search the sections for what you need I am not aware of other joints but I have not worked on an X1 so there may be something there. Re-check all work done just in case, check the start relay and all fuses Hope this helps Dave

Morning Peter Mark is spot on with his advice they are great cars and not as scary as many think if you are a DIY home mechanic. Our pot holed roads can wreak havoc on modern alloys tyres and suspension so check tyre condition and signs of uneven wear. History you can check in 3 ways Insurance (HPI) will tell of any untoward incidents Mot history will show if advisories have been attended to or ignored Service history will demonstrate general maintenance and with reciepts any other repairs. Check gearbox services have been done (often ignored) Good Luck with the hunt Dave

Morning Karl My money is still on the battery, simple test disconnect the battery fully charge it and leave it overnight if it looses charge that will confirm it The control unit by the battery is probably the PDC module. Water in the area doesn't help check the floor drains are not blocked (I guess your mechanic will do that) You could also check for a prasitic drain on the battery, battery fully charged car closed apart from the bonnet, let the car go to sleep (all systems off the tell tale by the gearshift will go out) then check at the under bonnet charge points for any discharge. There will be a small milli amp discharge clock etc, anything higher will need investigation Good luck Dave

Hi Daryl Welcome to the Forum First are you sure the Fuel Pump is running in the tank? The system normally self bleeds. You could try releasing air at the fuel rail pressure test schrader valve. Make sure you have plenty of Rag/Paper Towel there as it doesn't take much fuel to make a big mess everywhere. Either take out the schrader valve or depress the nipple while an assistant cycles the ignition for 30 secs or so. I have also heard of attaching a vacuum pump to number 1 injector fuel feed and pulling fuel through into the fuel rail that way, never tried that myself but worth a go. Good Luck Dave

Morning Justin Welcome to the Forum First the I would point out the Post you seem annoyed with (Wtf) is 3 years old ? Second the OP did close out the post by telling everyone it fixed his issue, success, saved a few quid and learned a lot I am sure So not sure what your problem is other than yo clearly wouldn't have done that Dave

Hi Shaun Welcome to the Forum I have read several times about this problem though not seen/suffered one myself From what I read the only solution is change the unit two choices, first BMW I have read £1k+ quotes and long wait times for parts. Second choice a used replacement first use www.realoem.com put the last 7 digits of your Vin into the search box it will call up your model get the Part Number for your car, double click the part number and it should show a list of any alternatives if they are available. Then Google to find the part and check prices Apparently it isn't a major issue to swap a DIY job then get your Mech friend to clear and reset codes Good luck Dave

Hi Steve Cold weather kills batteries get yours checked or charged would be my bet Dave

Morning Kirk Welcome to the Forum First the air suspension is a very simple system (compressor, pipework, airsprings and height sensors) the only issue I have seen is when cheap airspring replacements have been used or there is a leak at a joint ride height sensors need checking. Still that isn't your question, the answer is yes a straight forward job there are many kits available the job is just like changing the air springs. However you will need to remove the compressor and pipe work, plus code out the air suspension or the car will be looking for signal from the sensors. I would expect a good kit to cost around £200 Good Luck Dave

Morning Beth Welcome to the Forum When you say Vehicle History which bit, !st, is Service History this will indicate how well the car has been maintained. With older cars this will mainly be by way of a stamped Service Book and Reciepts for work done. 2nd. MOT history is always worth checking it will indicate if Advisories (Advised repairs) have been carried out or re-occur. 3rd. Are the Insurance checks ie. has it been in an accident and repaired (HPI etc) The DVLA hold information on all legally registered cars regardless of Registration number MOT information also includes The Vin Number (check it matches) HPI and similar hold information on Insurance claims, Finance etc Then of course there are the Physical checks when viewing the car such as, is the body work and paint in good condition, Tyres are they in good condition and evenly worn, Next the mechnicals engine off bonnet up the state of the engine bay will tell you a lot if it is clean and tidy all good if there is dirt oil and grime everywhere ? Before starting check oil water, power steering fluids is the oil clean and up to the correct level, same for the other two no visible leaks, check the engine hasn;t been run warmed up before you get there if it has it raises a question why? Now engine start and listen for noise's rattles sit in the car and make sure everything works as it should every switch button and knob, check the interior for rips or tears carpet and seats, check the carpets for wet or damp (sign of leaks) Last the test drive make it at least 5 or 10 miles single carriageway dual carriageway give it a real test. Don't fall for the "never used that never bothered me" or "easy fix you can get one on Ebay cheap" The MOT/Finance checks you can carryout from the comfort of your living room. The Service History while standing in front of the car same with the other checks don't rush it. If you can't do it yourself take a friendrelative who can Good Luck Dave

Hi Rob Voltage's are spot on so definately not Battery, all fuses checked and good ? A quick look at my copy of ISTA workshop information tells me you have Fuse 7 30a controls the ignition Fuse 13, 7.5a is Cluster Control Unit Fuse 41 is 5a and does the same job it could be the key, or barrel or a no communication with the EWS module a Diagnostic scan will show where the problem is If fuses are all OK have you tried recyncing the key incase it is that simple (you should find a guide on Google) Good Luck Dave h
