post-5895-0-85863200-1369271808_thumb.jpHello all,

The fuel guage on my M5 intermittently works/doesn't work. This is going to catch me out one day, I'm sure, since the car is partial to quaffing outrageous quantities of liquid fossils in small amounts of time. Couple that with the physics of time-flies-when-you're-having-fun and there is high probabilty of a situation involving a long walk and a plastic bottle.

I am hoping that it's easily remedied by replacing a conveniently located switch somewhere near the fuel tank....?

Could be a malfunctioning fuel-level sender unit or even a dodgy module !!

Other points to consider are "dry" connections and poor wiring...

It has also been known that a substandard car-battery can cause the clocks to misbehave ;)

      X3 2.0D 2012 F25 - tailgate struts on the way out?

      Hi Gary I did the exact job for a friend of my wife, I did a search of www.realoem.com for the correct part numbers left/right then she searched Google and brought both spindle drives for £110 delivered with 2 year warranty. Changing them requires trim removal so a decent set of trim removal tools and a Torx set will be needed. I did use a garden rake with a towel wrapped around it to support the tail gate as neither of the girls could reach 😅. The rest is straight forward, though getting all the trim out of the way is fiddly the job is plug and play. Couple of good Videos on line About 21/2 hrs work with Tea and biscuits 🤣 Dave

      X3 2.0D 2012 F25 - tailgate struts on the way out?

      Hello We have a LHD X3 we use mainly from driving from UK to Greece - the tailgate lifts perfectly well but on closing it stops halfway down - it will continue and close properly with some gentle assistance on the way down. The car was MOT'd at a BMW main dealer a couple of days back, we had a free visual inspection and I asked them to investigate the issue. As per BMW the 'motors are on their way out'. Given that their quote was shall we say rather strong (I appreciate it is a quite tedious job to replace them) my question is are the rams serviceable or are they really a replacement job?

      Help with 2014 X3 RDC and TPMS

      Morning JC Look like you brought a scanner that just does TPMS systems ?? I have 2 Diagnostic scan tools (1) BMW INPA/ISTA which is the same as BMW Dealers use and (2) iCarsoft both systems will give me a code that indicates which wheel sensor is at fault or if it is the Controller. Plus of course they also read all other control units on the car. With your monitor what does the Instruction book say? does it give a list of codes and their meaning? TP sensors do fail some have batteries in them they are not expensive to buy online (Ebay, Amazon etc) the costly bit is to fit them, obviously tyres need to come off and be refitted. If it was me I would wait until tyre change time Dave

      Help with 2014 X3 RDC and TPMS

      Thanks Greydog! I have not tried the battery unplug. But I have purchased Autel TS508 to try out and it found the error below from the ODBC scan. I tried to erase the DTC from this menu and the TPM is working again until I left the car for a few hours. Does anyone know what is causing the error? Thanks!

      No boost and strange noise

      Morning Jim A Seat owned by a neighbours wife from new but only used for school run duties was completely clogged at lower miles than yours. Predictably the Dealer said new Turbo new EGR and a swathe of other parts £££, a local Diesel specialist stripped, cleaned and rebuilt everything and gave her the advice to give the car a good run at motorway speeds once a month. Years ago my son had issues with his Toyota pickup the dealer mechanic told him an "Italian Tune Up" (engine up to temp and keep revs over 2.5k for half an hour) needs doing every few weeks. As a Tree Surgeon he tended to be trundling around off road at slow speeds and low revs. With luck it's just the actuator mechanism Dave
