Hi Matt

The is is a cracking car! Give the old gal a service first,then report back on the miss fire!

Did the fuel gauge work then stop? Or never work?

Welcome to BMWOC :)

Misfire could be plugs or a dodgy coil pack,the heater is more than likely the 'hedgehog' resistor,and fuel gauge is probably a fuse blown ????

A blown fuse wouldn't cause it.

Where is the misfire? Is it noticeable on idle or higher revs?

As it is a four-potter it would be hard to eliminate a coil-pack by just pulling off but bang a high-voltage meter across "Earth" and its "Low tension" feed and notice any shortfall...

... Other items to inspect are:

MAF

TPS

CPS

... And any air-leaks via intake hoses.

Good luck ;)

Looks like Dabs covered everything else :)

Hedgehog resistor is in the passenger footwell on the right hand side,they are a common failure...............have a look n YouTube for a vid to find it,its an easy change :)

      E53 petrol fail safe again.

      Morning Stu Long time since I played with a straight six so the old memory might be wonky here so check realoem From memory it is linked to the Air Pump and Vacuum control system. Find the Airpump and follow the Vac lines to the rear of the engine you should find a valve with a plug on top (or end) first make sure all lines are good no splits or cracks check the valve is operating, dont forget there is a non return vale in the system close to the inlet manifold. Hope this helps Dave

      Water leak at sharkfin aerial

      Morning Vic New one to me but I guess anywhere there is a joint is suspect. Like the seals around the rear lights that suddenly start to leak, removing them a good clean and renewing the seals seems to work. Check www.realoem.com to see what is fitted and how Dave

      Rough idle problem

      Morning Billy When was the car last serviced ? The symptoms you describe could be due to an air or vacuum leak, old hoses seals and vacuum lines can start to crack when cold they are stiff and don't leak (as much) when hot and flexible you see the issue developing. Your OBD Scanner needs to be BMW capable a standard scanner will only see critical functions. Dave

      Rough idle problem

      Looking for some help. 2010 116i M sport with the 2.0na engine. When cold, car ticks over perfectly. After about 15 mins of driving when idling you can feel it getting a little bit rough. Nothing too bad, but the longer you idle the worse it gets. No EML. When running car runs perfectly not a flicker. Today left it idling for 10mins after I felt it and then revs started to fluctuate but still no eml. OBD scanner can’t pick anything up. Turned it off and back on and was still rough but only a little bit like when it just starts. Anyone had anything similar or can point me in a direction of where I should start looking?
