'13 35d - Honeymoon is Over - P045F -Exhaust Gas Recirculation B Control Stuck Closed

[Best4x4xFAR]

Okay, new E70 35d owner..
Purchased last month with 55,xxx miles..
Has about 58,xxx miles on it now

About a week ago wife called saying the check engine light was on..
Two days later it was out (hadn't had a chance to go get the code read)..

Yesterday its back on..
Had the code read this morning..

P045F - "Exhaust Gas Recirculation "B" Control Stuck Closed"

Searched forum, but I can't seem to get anything to come up under the code, the description, EGR is 'too common' to search..

So obviously the Car is our of Factory Warranty..
Not sure if this would be covered under the factory extended emissions Warranty?

Any feedback/suggestions?

There should be a federal 8y/80k emissions warranty - Why don't you call your local dealer or bring it to them and tell them if its not covered under warranty you'll handle it yourself


No CPO either?

No CPO Warranty, bought from third party dealer. Dealer wants $160 diagnostic fee if no work is done, so would prefer to avoid that if it is not covered, particularly is it is an easy DIY (hoping)..

God this is bad advice...and I see it ALL THE TIME

There is a federal 8/80 warranty on THREE PARTS: DDE, CAT, OBD computer. (As I recall, read your manual)

SO many people blithely claim 'there an emsissions warrant, it's covered'.... Dealers are happy to collect $160 knowing FULL WELL it is not going to be covered.

Follow rickyboobys advice and you will piss away $$$$, They will take $160, then list $thousands of parts to replace and you will be no closer to REALLY knowing your issue.

Having said that, BMW has multiple parts warranties for some parts. Depends on what is wrong with your car.

Oh, don't bother 'wiping out' the 'carbon build up'.... Your issue is almost surely not that.

Well, from what I am reading there is the federal Emissions warranty with very specific coverage of those three parts..

But there is also a California Air Resource Board (CARB) Emissions warranty that covers many more components. My understanding is that it covers cars in California, as well as other states that adopted CARB regulations, Maryland being one of them.

Starting on page 31 of the 2013 Service and Warranty guide is a list of components covered under the 7 year/70K mile CARB Warranty.

'EGR Valve (Low Pressure)' is one of the covered parts, along with the 'exhaust cooler for EGR', and many other high dollar parts like DPF, Turbo, fuel pumps, fuel injectors, etc, etc..

Caveat here may be the wording. If the vehicle fails emissions inspection. Well MD doesn't have an Emissions inspection. But it can be argued that it can't be inspected with a Check Engine light, so it would fail by default..

I dunno, service advisor hasn't gotten back to me (big surprise there)..

I need to finish researching and purchase a solution for reading codes, and diagnosing issues I guess (see post about Bimmergeeks product)..

Yes.

That is different from the fed warranty.

It is not a 'if it fails we cover'... it is "if these parts fail they are warranted"

IMO you need to figure out how to diagnose your issues and once you prove the parts are bad, THEN go to the dealer.

Which is why I suggested he go to the dealer - diagnosing the complex emissions system and multiple components that fail by saying what "P" code he is throwing is going to get him nowhere

If you buy a BMW out of warranty and especially a BMW diesel you need to be prepared to do two things:

1) Spend a good amount of money at a independent BMW mechanic or alternatively the dealer if you trust them, to keep the emissions system working and intact as there are multiple components that will fail at some point or multiple times

or

2) Deletes

Since OP is sticking with keeping everything intact, he needs to be prepared to pay for proper diagnostics, and component replacement costs - yes some parts will be goodwilled, and yes I'm aware the Federal Emissions warranty is EXTREMELY limited, however, the CARB warranty is helpful to him, if his components qualify - (there is a gray area I read where he needs to need emissions testing in order to qualify for it)


I did post this above as well in a later post on the thread, since you only really read my first response - https://xoutpost.com/1052272-post3.html - which clearly agrees with what you are saying -


Either way, a diagnostic fee is only charged when the work isn't being done by the dealer to reimburse for their time, I recommend he go to the dealer, have them diagnose the problem properly, and fix it (which is likely one of the EGR valve) properly, and be prepared to have random things in the emissions system that need to be fixed properly in his ownership -


I was lucky enough that my wifes 2013 CPO still had factory warranty for about 8 months, and boy did it come in handy, between 42k when we picked it up it needed the following a week later:


-both NOX sensors replaced (those are pricey)
-Power steering pump (that was a WOW) considering the miles, with deflection/idler pulley)
-Transmission sealing sleeve (tech said it was leaking)


2 months later CEL back on and no issues driving, take to dealer and its throwing SCR efficiency code so the following was ordered and replaced under warranty as it took a month to come in-
-SCR Catalyst (another pricey item)


I have the service records from the first owner of her car, both DEF tanks and metering nozzles and sensors were replaced at 35k as well.

Your posts indicate you believe there is an 'emissions system warranty' for 8/80. There isnt.

[Best4x4xFAR]

Well, the dealer is doing its usual vague BS, can't tell me anything till they look at it, $140 Diagnostic fee, whether it is covered or not..

Not surprised I guess, was hoping someone would throw me a bone on their experience with emissions related repairs outside of warranty, but they clearly weren't going to do it..

But I don't have a BMW specific scan tool, so I guess I am at their mercy (or an indy) at this point...

Are they not able to tell you if emissions components related to the EGR system are covered under emissions warranty?


There are so many components it is almost impossible to troubleshoot the emissions system without dealer software, and even then a lot of times they throw parts at it - it should be easy to explain to a service advisor that you are throwing codes for the EGR system, its not a glow plug for example. Alternatively, find a good independent BMW diesel mechanic/shop. However, P codes tell next to nothing and you really need to run dealer level troubleshooting software (ISTA+P? I believe) as they will have test plans for the codes thrown in order to pinpoint the failing component. The EGR at the front of the engine and the EGR cooler is easy to get to if those components are failing, but again, throwing parts at it is a crap shoot - and emissions components are NOT inexpensive.


Do you live in a free state that doesn't have emissions testing for diesels? I see you're in Maryland so its doubtful. Thankfully we do, once something fails in the emissions system that is not covered under warranty, my wifes will be getting full deletes and amended tune to match.
