Hey Fernando. All injectors were returning 30ml flow where as #6 was returning 70ml back flow.

Apparently the reason the injector wasn't sealing is the flange that holds it secure is snapped and it was rattling around loose and letting compression out.

Quote is to recut the seat for injector 6, new injector and replace all washers, seals and clamps on all six injectors. All the seals and washers stuff is cheap and it's almost a case of may as well do it while we're in here.....which I don't mind, the expensive part is the new injector.

If you PM me your email i am happy to forward you a copy of the work order?

Well, it's just getting better.

So I have contacted the dealer, who has of course pointed me in the direction of the warranty company who is managing the 12 month warranty that he (in effect me) bought for the car.

The warranty company has said I need to take the car to one of their authorised repairers for diagnosis. I explained that the car is sitting at a mechanic with the manifold removed and two injectors out.....which was required in order to establish that it was in fact an injector issue, and thus a warrantable item. The estimate is $3k. They don't care, and they won't approve his quote under any circumstance. So I have paid $250 to have the problem diagnosed, and now have to pay to have the car reassembled (not fixed) and drive to their mechanic. IF their approved mechanic diagnoses an injector fault, max payout is $1250 (which is basically what an injector costs). So I'll be $400 down for the initial mechanic's work, plus have to pay to re-diagnose the same problem and establish the injector is at fault (warranty company requires injector to be sent for bench testing ....also at my expense) PLUS have to pay any gap to the 'approved' repairer on the total job.

So it's a bit of a headache, and either way I'm going to end up heavily out of pocket.

OR - I try invoke my statutory warranty against the dealer, which means engaging Dept of Fair Trading, which can ultimately end up in court. All the while my car remains un-repaired.

Obviously this can happen to anyone, so it's just bad luck - and if I'd bought the car privately I'd have no option but to pay it all myself.....but it just leaves a filthy taste in my mouth knowing the car has been driven less than 150km's since I took delivery and already I'm coughing up.

Rant over.

Course of action from here is to have all the work done EXCEPT installing a new injector. Also getting things like PCV, fuel filter, EGR etc taken care of at the same time. Hopefully by replacing the injector cradle/cap, putting a new set of washers and seals in it will stop the compression leak and just may fix it - if not we'll know 100% it's the injector and I'll be able to dump it at the feet of the 'approved mechanic' and accept nothing less than a new injector under warranty.

Sad to hear of your problems SMOKEY53.

The statutory warranty over-rides the 12 months extra bought warranty.
As long as you are under 10 years old and 160,000 kms, the statutory warranty applies for the first 3 months / 5000 kms.
The dealer should pay for all the repairs, and even towing if it is undriveable.

You are meant to contact the dealer where you bought the car first though, before having anything done, otherwise thay can pretty much say bugger off on the statutory warranty.

Whatever happens, I hope you get this sorted quickly, so that you can actually drive and enjoy your beast.

Good luck.

Mat,

Something screwy is going on here. If yours takes the same injectors as mine (part number 13537789670), then they are available for under 200 bucks ex-Germany. Don't die in a ditch over genuine BMW - the injectors will likely be Bosch anyway

Yep, I'm aware. I did contact the dealer first, he told me to get it diagnosed at a mechanic. So I did that. Then contacted him with the verdict, he deferred it to the warranty company. Warranty company said I should have contacted THEM first and that they didn't authorise the diagnosis so won't pay for it - but I pointed out that I had to do the diagnosis in order to establish that it is a warrantable item. I'm basically getting ping ponged between them both, neither wanting to pay out.

Mean while my car is sitting in pieces and my partner and I are making do with one car.

I know that I could pursue stat warranty, but they're only required to repair it to a condition commensurate with the age and km's, so they're already talking about putting a second hand injector from a wreckers in etc.....I just want the car fixed, and fixed right through a reputable business. Not a Band-Aid job to get me outside the warranty period. The dealer is also within his rights to tell me to take it to someone else for a second opinion, in which case I'd have to pay to get it put back together just so I can take it somewhere else. Trust me when I tell you that this dealer is as crooked as a question mark, I only know that now in hindsight. As an example, his first response when I told him of the issue and asked what he'd like to do as a next step was to tell me I had no statutory warranty because the car was unregistered when it was delivered; which is a blatant lie.

Ants, that's an interesting piece of info. The injector part # is the same on the quote as what you've listed, and the RRP is $1,339+GST It's no surprise when these mobs get a bit shirty when you offer to supply your own parts....


As I said, I've pretty much opted to do all the maintenance work required to get it in order EXCEPT the injector. If it all goes back together and the problem is still there, even if intermittent, then we'll know 100% that it's the injector and I'll hopefully get that replaced under warranty.

Just checked eBay - right you are ! But like I said, hard to find a workshop that will let you supply your own parts.....their labour is $140 an hour but you take that 30-50% mark-up on parts away from them and they start to get a little less accommodating, and you'd end up paying the difference in inflated labour.

Things like the smoke on startup - mine does that. But I'm not worrying about it until winter comes around again as I'm certain it's either glow plugs and/or controller. And aftermarket Tridon glow plugs (nothing wrong with them) are about $30 each...

Even the injector - would be worth talking to a diesel specialist about getting yours refurb'd.

If it were in Canberra, I'd recommend Cooma Diesels, but in Melb, mate I have no idea sorry

Sometimes you are better of saying "Sorry guys, I can't afford to do this right now, can you please put the car back together and I'll just have to take it home and park it for a while"....

Then take it home and do it all yourself

Easy enough for me to say - I'm a qualified mechanic - but they are pretty ballsy carrying on the way they are.

Those warranty mobs are pirates. Pure and simple I reckon.

Not exactly an engine flush but I used to do it on all my E39's...
Drain the oil, put the plug back, pour in the engine 1 gallon of diesel , start the engine briefly for 3 seconds then shut off, let it sit for about 15 seconds then start again for 3 seconds and turn off.
Drain the diesel , follow with the filter and oil change.

Yeh - well as an example, my BMW Scanner said glow plug #3 was faulty. They've recommended replacing all 6 + controller at total cost of $600+gst.

Do you reckon that it effects running performance though? or just cold start. I've found documentation that they're active on startup and when coolant is under 30degrees and also have an afterburn function when coolant is below 25degrees. Workshop says they help burn off emissions returned to the cylinder by EGR - but planning to blank EGR off anyway. So just not sure if it's worth replacing them just for peace of mind?
