CEL 1213 on 540iA

[Tiger]

Augh... CEL 1213. The symtoms is first thing in the morning, engine is rough and CEL light up. After driving and warm up, CEL goes away. Sometime it is quite roiugh in morning that the engine will stall when trying to back out of the driveway. Just a matter of throttle technique stops the engine from stalling.

That was several months... and now CEL is on all the time. I know I will have to do diagnostics...

fuel pump is original with 137K miles.
intake gasket and ICV done by dealer at 96K miles
MAF is original
MAF boot is new a couple of years ago.

Fuel mileage is not great... keep going lower over long time... now at 15MPG for strictly city driving. It used to be 17+ MPG.

Where to buy fuel pump without paying $300 for it. Recommended pumps?

Help is very much appreciated.

unplug the motronic deal and let it relearn, we all know these mess up for no reason, unplug and replug, done. if it consistently goes the same code you may have an issue, but until then don't worry. I have the 1212/1213 code for over 100k... unplug and replug... same shyt many months later.

Bill R. was not so happy with the cheap no name fuel pump from Ebay

No name pump... yes I seen those too... but this unit is Bosch. More tips from you is greatly appreciated Shogun.

The car has minor hot start problem for long time... and now I am having cold start problem too... takes much longer than 4 seconds of cranking to start up the car. I think I should change out the fuel pump now... since we know BMW OE fuel pumps does die regularly.

I will call up a friend to come over and hook up fuel pressure gauge to test the system.

Ya know... if you keep getting this problem... might as well fix it.

My M-Sport has 182k miles and the original fuel pump is still quite ok. It did just get it's third MAF if I'm recalling correctly. It run/start any better if you unplug the electrical connection on the MAF?

It seems to run smoother with the MAF disconnected.

We found air leak at the throttle body to intake manifold with carburator cleaner. Unfortunately almost all torx head stripped out as we try to remove the 6 bolts... so we decided to just yank out the whole intake manifold and do the whole job.

My water pump is also leaking so I have to change it too and will change the tube oring also in back of engine while the intake manifold is out.

I plan to send my fuel injector to have it cleaned and flow tested..

It's a fun job!!!!

Now I am looking for a write up on this job... I can't seem to get my coil pack module off the engine so my intake manifold have free room to get in and out.

Thanks for the offer... I just got the manifold out. Now I have to order lots of parts.
