Re: Pinking (pre-ignition) 1999 2ltre

Not wishing to stray away from pinking and knock sensors etc,bikes have been badly affected,my son's Kawasaki tank leaked and his friend had leaks everywhere on a suzuki, brit classics such as TR6 and jaguars also fared badly owing to this, to mention just two makes. On bikes as you found,plastic ta...

Re: Pinking (pre-ignition) 1999 2ltre

Yes,I am finding all this lowering of hydrocarbon content in fuel a bit curious,don't get me wrong-I am all for the planet and want to do my share to mitigate atmospheric pollution.The motorcyclists and classic owners are tearing hair out as fuel systems collapse since Ethanol introduction. Handsome...

Re: Pinking (pre-ignition) 1999 2ltre

Just back from Texaco where they have reduced down to just one 97 super plus pump,expect they all have them. Can't comment on Tiverton but was in Croyde in August and bought superplus on the Braunton road without problem. You shouldn't have a problem from forecourts selling the brands discussed. You...

Re: Pinking (pre-ignition) 1999 2ltre

Sorry for the double post,problem is,it is doubtful that BMW ever expected their engines to have no choice but to run on today's dire and highly varying fuel so possibly even when fully retarded,the spark is still lighting up the mixture early. Another thought,I had my head refaced when changing the...

Re: Pinking (pre-ignition) 1999 2ltre

Just found post 15 mention of fuel used is 97-have you tried all brands?
Not convinced this is Piezo knock sensors or glowing carbon deposits.

Re: Pinking (pre-ignition) 1999 2ltre

What brand/octane rating fuel are you running? My previous z3 was fussy about fuel and,like my present one is only happy on super plus 97 rated fuel. The last car would pink for one or two firing strokes before the knock sensors picked it up and the ECU would retard the ignition map which would alwa...

Thanks for the link,not used on all engine variant z3 models it would seem. Don't recall it ever having been mentioned on the forum before.

Re: where is the sensor that reads vacuum ?

The M44 along with M43 engine uses a MAF and the car is not fitted with a MAP sensor,these were more commonly found on earlier EFi systems by other manufacturers.

Re: Temporary brake failure - advice

Some years back this happened to me in a 9 month old Volvo without warning whilst approaching a roundabout (luckily quiet with little traffic) felt like all brake fluid had been drained but reservoir was to max line. Pedal returned to normal but I drove very cautiously for a few weeks and again, ped...

Re: The Inn at Welland, Nr malvern, Worcestershire

Drove past while your car was on car park near door end around last weekend ISTR,had just renewed my DISA valve and was taking it easy on road test as Welland has very regular speed camera vans. If I had known it was a forum member I would have stopped and said hello but it can be a bit like waving-...

Re: Secondary air pump M52 TU any tips thoughts?

After years of maintaining a standard look engine bay,last week the inevitable secondary air valve decided to go to straight through mode and so I decided the pump and valve had to go. Removed pump and pipework but replaced bracket from pump as it carried charcoal filter purge valve,made Dural blank...

Re: BMW Z3 ROOF WITH EXCELLENT REAR WINDOW.

And thank you!
Enjoyed the drive, top down in pleasant weather and left with a tremendous spare hood ready for that inevitable day.........
The description totally matched the condition and I would recommend buyers without reservation.
