Possible dead 1 series

[Dominic H]

Afternoon all,

I have a 2007 120d auto with 91000 miles showing. It was an AUC car 3 years ago and is BMW main dealer maintained.

At the weekend my wife was driving at 70mph on the motorway, when there was a sudden loss of power. She was able to make progress home at around 40-50 mph, as she was only 10 miles from home. Once home, I examined the car to find that it started, idled and reved in neutral seemingly correctly. I drove it around the bloke, it was fine up to about 20mph, any faster and there is a noticeable sharp/shrill noise.

The car is under the BMW driveline warranty so I took it to the local BMW main dealer on Monday morning. They have just called back to say that it's not looking good. They have read the OBC and a number of faults are showing;

Fault on EGR
Fault on DPF
Fault on inlet manifold
Fault on glowplugs
Fault requiring software update
Possibly more

An itemised estimate estimate is being prepared, but as a guide it was indicated that the parts would be over £2000 plus labour plus vat.

Bearing in mind it is worth £3000 on a good day, the cost of the repairs are going to be more than the car. Are these faults repairable at a sensible budget, or is an otherwise sound car just good for scrapping?

Cheers

Unfortunately without more info/pics any help is going to be purely guesswork.

eg.
Fault of DPF.
£0 - forced regen. £1000 full price BMW replacement.

Fault on EGR.
£0 strip & clean DIY. £300 replaced by BMW

Fault on inlet manifold.
£50 Strip/clean/new gasket DIY. £500 same job done by BMW.

Don't quote me on any of the prices above they are just wild guesses to illustrate the point.

If you see what I mean.

Thanks for the feedback. I will have a detailed estimate later on, which may fill in the gaps. You're a little more encouraging than the call from BMW a hour or two ago!

I have just re-read your thread & something else struck me.

The noise that you mentioned at 20mph, what did it sound like & where was it coming from?

Also did your good lady describe any noise with the sudden loss of power?

The reason I ask is that all of your faults COULD POSSIBLY be explained by a dead turbo.

A dead turbo which would be covered by Driveline warranty?

Having no idea of the Ts & Cs of the warranty, I couldn't possibly say, the OP should be able to check though.

Is this not related to the big electrical recall on 1/3 series?

If it was turbo you would have expected bmw to mention boost pressure faults logged. It sounds like dpf is heavily clogged, possibly caused by egr being stuck open and the noise you hear could be pressure building up inside the crank case as it’s strugglin to escape through the exhaust.

Get a list of work needed from bmw

At the minute it doesn’t sound terminal for the car, where in uk are you? Someone I’m sure can recommend a good indie if needed

[helix402]

If op has a drivetrain warranty doesn’t that cover the faults? (At a guess glow plugs/glow plug controller, egr valve, forced Dpf regen/chemical clean, thermostats).

Swirl flaps may be failing too.

Whatever the faults are --- you took a 2007 car to a main oil changer ! go and recover your property before anything else gets done and find a well regarded specialist in your area .

[helix402]

Hasn’t it got a BMW warranty though?

[gizlaroc]

Surely if you have driveline warranty, that covers it anyway?

[Sardonicus]

Sounds like a choked DPF (inc the strange noise) it wont regenerate while there is glow plug fault codes and a faulty EGR valve will only accelerate the possible cause ....... my cents worth , like mentioned already find a dent independent they will go the extra mile rather than plastic card snatching main stealers

Also check the thermostats are working right, needs to get to 90ºc and stay there rock solid, if not, a good chance it is dropping below 78ºc when on the move and again the DPF will not regen, so it will block and give the symptoms you describe.

Sadly no...

Plan to do so Elliot. I'm in Bromley, Kent. Hoping that several faults won't kill an other wise good and well maintained car.

Sadly no. The driveline warranty covers the big expensive bits, engine/gearbox/turbo. The small expensive bits aren't.

Thanks Charlie, they're not all bad and nothing is being done to the car except a big estimate to replace expensive parts.

helix402 said:

Not these bits...

Thanks, this seems to be a recurring theme. Will go to Indy once we know what's wrong. Have driveline warranty from BMW so that was the first course of action.

Thanks will do.


Thanks everybody for the advice, much appreciated.

Are you at stephen James ruxley bmw? When you get a definitive list of work, let us know as I’m sure they will say it’s all essential work but things like the software update is unlikely to have an impact on the fault you have

Right, I have the estimate from BMW. There are three areas that are showing permanent fault codes;

DPF at £1485 plus vat inc bits and labour.

Glow plugs/pre-heater at £555.05 plus vat inc bits and labour.

Fuel heater £829.52 plus vat inc labour.

A total of £3444.58 inc vat and parts.


It was explained that the inlet manifold was also showing faults and was likely to be blocked. There is a strong likelihood of additional costs once they'd started the work.

I guess the next move would be to see if any of these issues/parts can be repaired rather than replaced at an Indy. See what the non-franchised cost would be. Then take a decision as to whether its worth doing. As per the OP, it seems a shame for an otherwise well maintained, reliable car....

So they've all failed at once? Righto.

A decent ordinary garage is the next place to go.

I'll give you £300 for the car as it stands, collected by transporter.
