Replacing Injectors - Advice Appreciated
Discussion
Hi
My E92 330i is in the dealership at the moment, and they're quoting me a lot of money to fix it. I thought I'd run it past you lot to see what your input was.
Symptoms:
Struggles and misfires at low revs under load. E.g. at 60 mph in 6th, giving it some welly will cause it to judder. Then, the engine management light comes on, and it feels like it is firing on less than 6 cylinders. Turning the car off and on again fixes it usually, but you can make it happen at will, all the way down to 2nd gear at about 1000 rpm. I was having to drive it a gear lower than normal all the time.
Took it to a dealers a month ago when staying away for business. They had it from lunchtime on thursday to close on Friday, and their outcome was to clear error codes and update the car's software to the latest versions, which apparently is the standard procedure.
I was never totally convinced it felt right, and one month later after a long journey it happened so easily that the EM light wouldn't go off after a restart. Took it to the dealers, who have run their tests and said that the error codes show 2 injectors & coils need replacing.
However (and this is the bit that sounds a bit like bulls
t) their strong guidance is to replace ALL 6 injectors and ALL 6 coils as ''the rest are more than likely to follow suit and that would cost a lot more in the long run.''
In fact the service advisor told me that entering the part in the system (or whatever) brings up a recommendation to replace them all.
Total cost estimated at around £1,500 ballpark.
Does this sound reasonable?
Was I born yesterday?
Did they see me coming a mile off?
Any advice?
Thanks, BMW people.
Oh - I imagine this is irrelevant as the dealership makes their money either way, but they are trying to get BMW to pay 50% of the cost as a goodwill gesture, as it's something like 8 months out of warranty. Which seems relatively fair.
Thanks in advance.

Sounds like there is a good chance this will cure the problem, and by doing all six instead of just the ones that have failed will prevent you having the same problem again, or if you do, you will know to look elsewhere for the fault.
I would get a quote from an independent garage for the work. I'm sure you can get this done for a huge amount less than £1,500.
Also you could go down the route of replacing all the coils, see if it fixes it, if not then replacing all the injectors. Assuming replacing coils will be cheaper than injectors, you could fix the fault for a lot less if the the coils fix it.

Thanks all, useful so far, although I don't really know what to do with the info.
It does seem amazingly suspect to me, and given that it's £700+ of my own cash (best case scenario) I am tempted to try and get a second opinion from someone.
Don't know/trust any indy dealers, though. And I need the car back pronto.
Bah!

TheCaseAce...where abouts are you?
There's a list of tried and tested Indies here if you haven't already seen it:

Thanks all.
Called the local Independent - they quoted £250 to replace the coils, then they'd come back to the injectors if that didn't fix it. They would be buying the injectors from the same place as
Main difference is £50 p.h. labour rather than £120.
Dealership has reduced total cost to £765 and provided a loan car so I've just gone with that for convenience. Also, Full BMW history maintained. Not sure how much that matters on a car I will probably PX with BMW but there you go.
In fact, does getting a repair done by a non-dealership even count towards "service history"?

Did the dealership reduce the price after you told them you got a cheaper quote? Is it for the coils and the injectors? if so well done.
Getting a repair done at an indie will not matter as far as service history counts, however I understand you going with the main dealer anyway for the convenience with regards to the loan car.

TheCaseAce do I take it that this car is out of warranty ?
I have the same model as yours and a couple of weeks back I extended my warranty to comprehensive so want to make sure those parts you have mentioned are covered by the warranty.
I was told they are covered but just want to be sure.

Do the new injectors + coils come with a warranty?
Yes, 24 months parts and labour warranty on fitted genuine BMW parts.The guy who was told there was no warranty presumably had them fitted by BMW under an existing warranty that was about to expire - you only get the 2 years if you are paying for the work.

I think I have had the most failings of coil packs/injectors on here so far - think I am up to 4 or 5 issues since new (2008). BMW tend to replace a coil pack at a time (the one(s)) that are flagging up as causing as issue. They replaced all six of ours last time as we were fed up of continual problems.

In the short term, I would replace just the one that is causing the issue. In the slightly longer term, I would sell the car and get a BMW with dealer warranty - they are a money pit.
Just thought I would update this to say the exact same symptoms have reocurred, as Toxicnerve suggested.
Today they are quoting me £1,051 to replace the High Pressure Fuel Pump and the NOX sensor. Apparently even though the same symptoms have occurred 3 times in the same year, they are different faults.
I am calling independents to discuss.
P1ssed off!

Indie garage was wonderful - suggested I go back and lean on BMW much harder to get more than a 50% goodwill gesture as this part fails all the time on this model.
Car history:
March 2009, HPFP and NOX sensor failed - replaced under warranty
- Warranty Expires, Owner (me) Too Thick To Renew -
Jan 2011, HPFP reprogrammed (£200)
March 2011, 6 x Injectors, 6 x Coils, 6 x Plugs replaced (£800)
June 2011, HPFP and NOX sensor failed....... (asking for £500)
Dealership says "it is a 4 year old car, sir!" as if it's amazing that the car still even works. I swear they get into the mindset that everything over 40,000 miles is a banger.
Anyway, waiting for them to get back to me.
Even a cursory search on the web returns fistfuls of evidence that the HPFP on these engines is crap. RealOEM shows this model has 5 different iterations of HPFP - 3 of which have been discontinued since 2009.

I would be kicking off big time. These cars have an inherent fault in the coil packs, injectors and HPFP and BMW don't seem to care about rectifying it.
