$3040.00 to replace rubber tubes? What are the smoking, because apparently I need some of that!

Here's a link to a similar thread at Motoring Alliance: http://www.*********************/for...1498-code.html. I'm guessing they are referring to the tube in the diagram below (#13):



Per the diagram above, #13 goes from the fuel pressure regulator (#7) to the intake manifold port indicated in the two diagrams below:





This is the same circuit that is modified when doing the VGS mod. You can see many more pictures there: https://www.northamericanmotoring.co...ystem-vgs.html. This is a really long thread but is worth reading if you have the spare time.

In summation, that's a fairly easy tube to get to. You might have to use some needle-nose pliers to get to the fuel pressure end (since it's between and below the intake runners).

 

The P1498 code, got it today but when cleared it has not come back yet.. My Cooper is a 2005.. Non S..

 

R53 JCW, 244K miles - very well maintained about every part has been replaced with new OEM....and I mean about every part at least once, except engine and transmission.

Have been sporatically seeing a P1498 code for past 4 months....Started in December during colder wx. It's mostly a garage queen now so doesn't see much daylight...Replaced the MAP sensor above the upper radiator hose...nada. Code came back. Smoke tested the vac line and BMW performed an test of fuel evac system elctronically and all was good.

Today temps were about 38-40* - started it up, pulled out and parked it with engine running for about 3 mins to warm it up.

Went to leave 3 mins later and I saw that the EML light was on.

Checked SGII mounted on the dash, the code was not initally readable...So turned off ignition, put key to pos2 and pressed "read" - P1498 code rears it's ugly head again! No other symptoms....Car has no driveabilty issues and sounds strong up through the entire RPM range.

State Inspection in July, so need to get this sorted out.

I was going to replace the Detroit Tuned BPV since it has over 200K miles on it, but after ordering on line with brief synopsis of my situation, Chad was nice enough to call me to say he's never had one of those needing replacement. The springs are thick and strong and just dont wear out.

So meantime, I've ordered a bunch of vac lines associated with the fuel preporation system, and the one for the FPR ( fuel pressure regulator ) and the metal gasket for cold side of the supercharger horn, and gasket for TB.

Will dive into the GP intercooler tomorrow and check the rubber boots but those are OEM and practically brand new at 3,000 miles ago. Cant imagine those are cracked.

If anyone has solved this w/o shotgunning a slew of parts at the situation ( all at once ) please let me know.....LMK !

Thanks in advance !

 

I had the dreaded P1498 showing up intermittently. After replacing all vacuum hoses, the throttle body to supercharger duct, & all associated seals — to no avail — it turns out to be this thing:



The O-ring between the bypass valve & the intercooler duct that bolts to the intake manifold had gotten hard & shrunk with age. It's included in the head gasket kit; ostensibly for a reason! My bypass valve was fine. Replacement isn't too difficult, you can do it without going into front-end service mode.

Hope this helps!

 

Well that's good to hear....I have a DT BPV, and while they never go bad I was definately concerned about that gasket.
I ordered a gasket and got it from MINI already, and purchased a new DT BPV as well.

It's one of those, "while your in there" situations and would be kicking myself in the *** if the BPV goes belly up after already being in service mode for this gasket.

I also have all the related vac lines too...was over $200 dollars for just for those...

Thanks for the input !!!

 

My BPV is stock, & still works great.

If you think about it, this makes perfect sense. P1498 = Unmetered air after supercharger. That is exactly what a bad BPV O-ring would cause; though I can't see very much air being able to get in. I guess it goes to show the sensors & the ECU are VERY sensitive.

 

One time before this it was the green "jam" gasket at base of the black duct horn....will be doing that and duct as well but during disassembly, I will take notice of both and see what comes from it. Right now it seems to happen either shortly after start up while warming up in driveway, then goes away after shutting down and starting back up again....

 

I would strongly exhort you to do the BPV O-ring while you're in there; it's not much work & the O-ring is cheap (about $10.75 at Pelican).

 

Positively.....It will be done soon during service mode for a SC service. Will do BPV/gasket, throttle body gasket, replace the M7 180* thermostat and gasket, replace all vac lines, crank sensor and crank sensor o-ring, SC horns metal gaskets and examine the coolant hoses....in 234K miles the car has been in complete service mode two times...this will be the third.

I'm not one to "wait" for stuff to go bad...but when something does anything around it gets done too especially if we have to go deep to get to it.

 

You have your priorities straight, respect!

 

Eurothrasher, were you able to resolve the P1498 issue? If yes, what do you think it was (BPV O-ring, etc.). I'm running out of ideas for my 06 MCS and am 8 months overdue for CA smog.

 

I did !
Was going Covid stir crazy....I had all the parts, tools and garage and temps were in the 50's so dove in ! Gave the GP intercooler a cleaning with CRC Non-Chlorinated brake cleaner, repalced BPV and gasket ( BPV was fine even after 180K miles - but had new Detroit Tuned BPV in tool box ) replaced gasket for throttle body, and all the vacuum lines with OEM except for the one at the lower duct horn. Will do that during next supercharger service.







I found a missing gasket !

I had a supercharger service done some time back and the tech forgot to re-install the metal gasket for left side aluminum supercharger horn.


Red arrow point to a new gasket.....

Black blow by was clearly visible around the joint area where it connects to the aluminum intake manifold.
Unmetered air was entering the intake chamber....MINI calls to replace these metal gaskets EVERY time they are removed...my guy just forgot to re-install it altogether...

Like new again....

 

Wow! Congrats on the fix and thanks for the detailed response. I've had the horns off the SC when it was serviced (new oil) last year but I know the metal gaskets were not replaced with new. Thinking I'll replace those, the throttle body gasket, and the BPV O-ring because I smoke checked the emission vacuum lines with no noticeable leaks. Do you know if the DT BVP O-ring is OEM? I don't see the option to buy it on their website.

By the way, that is a sweet looking engine compartment - nice work!

 

Thank you !
Yes, Detroit Tuned BPV starts out as an OEM BPV.

They add a diff (stiffer) spring, align and adjust the gate.

My first one had 180K miles on it ! Gasket didnt look too good, but BPV itself was fine.

I doubt I would have got 180K on an OEM one....

 

Random question: What's that thing sitting on top of the intercooler? Some sort of water cooling for the intercooler?

 

co2 spray bar

 

Off topic question - Eurothrasher, where did you get those AWESOME red intercooler clamps?!

 

As another data point on the P1498 code, I started down the road of "easiest to access" fixes ( both MAP sensors, throttle body gasket, etc) before pulling the nose off yet again. The final cure for me appears to be one or both of: re-sealing all of the plastic welds on the tube between the throttle body and supercharger ( black silicone) or replacing the vacuum line between the PCV and supercharger inlet. I have a DT bypass and as it was new less than 1000 miles ago, did not feel the gasket was the culprit for me.

70+ miles over 4 drive cycles so far and no EML or CEL where one or both would pop up within a few miles over any drive during the past year!
