thinking of a 335i - it has had a new engine, any problem?
Discussion
I'm considering a 2007 335i. It's under BMW extended warranty and had an engine replacement (under warranty), quite recently. It's on around 40K miles.
Just curious if this would put anyone off? I have to say, it's not something that terribly concerns me and it has 10 months BMW warranty to run. But I change my cars quite frequently so resale is an issue.
Any thoughts?

Depends on the reason for the failure I suppose.
If it's been chipped (it is a 335 after all), then that might have been the cause, and then you'd have to worry about all the bits that weren't changed (i.e. all the bits that had eleventy-hundred horsepowers through them until the engine went bang).
Or it could simply be a duff engine or component that's failed requiring a new engine - exactly what happened to my Z4M. The EML light came on, a patrol came out, couldn't fix it at the roadside, took it to the dealer, and got a new engine under warranty.

As long as you don't plan to let the warranty expire so that when the engine next goes you should be OK.Just curious if this would put anyone off?

The problem was with the old engine ... which was replaced ... so the new one should be fine ... but I know what you mean in respect of what other people may think.
I would try and find out a bit more as to why it was replaced, but if if was replaced by BMW, the car has a BMW warranty and service history then just see how it looks and drives
I had a TVR Griffith a few years back with a new engine (not actually common on the 'Rover' V8 TVR's) and ended up thinking of it as 'new' as a result ... the old engine was replaced due to a piston failure.
If the car looks and goes OK then don't worry - subject to knowing more

Thanks for the input. The reason for replacement was...
Engine was replaced due to a problem with not burning ethanol properly which caused a build up of carbon on pistons. Apparently the clutch was also replaced when the new engine was fitted.
I have no idea what would cause this issue but it seems to have been addressed properly.

You mean they have redesigned the engine to avoid carbon build up?Engine was replaced due to a problem with not burning ethanol properly which caused a build up of carbon on pistons. Apparently the clutch was also replaced when the new engine was fitted.

I don't mean anything....I have simply provided the explanation as given to me. If you're trying to say that these engines are prone to this issue then say so? If not, then my preference would be for helpful input.

Q: Do you think other potential buyers might be put off further down the line when it comes to sell?
A: Yes. I would be and I'd ask you what went wrong with it and to show me some proof from BMW that this was the case. If you couldn't back this up then I wouldn't be interested. I'd also try to find out about your car from BMW.
Q: Would I regard this as more hassle than it is worth considering that there are enough 335's out there to choose from?
A: Probably. Unless you were offering it up at a discount...which, I assume, you wouldn't be (and why should you?) I'd probably look at some others before considering yours.
Don't know how this sits with other people but I'm weary enough when it comes to buying cars without having the added worry (with warranty or not, for me it is psychological) about new engines etc...

Your response is pretty much why I asked the question.
The car looks a good example and is well speciied at a reasonable price. Having 10 months of extended warranty remaining is also a bonus.
It's a new engine which has been supplied and fitted by BMW so logically it should be a positive thing at 40K miles. I've got to say I originally looked upon it as a bonus.

Original and/or previous owners running it exclusively on cheapo high ethanol content supermarket fuel perhaps........????????Engine was replaced due to a problem with not burning ethanol properly which caused a build up of carbon on pistons.

A lot of modern engines suffer from carbon build up, not just BMW's, and require a "de-coke". The problem is, this carbon build up isn't the traditional hard, brittle deposits that many a classic engine re-builder is used to, it's more of a thick, treacly sludge that gets everywhere.
BMW will have replaced the engine because for them it's quicker and cheaper than stripping the old engine and spending the time to remove the sludge, plus BMW Germany may well have asked for the complete engine for examination.
The clutch will have been replaced at the same time simply because there's no real additional cost incurred whilst the engine is out apart from the cost of the clutch and it gives added piece of mind to the owner that the clutch is new.
To Me I'd see the replacement engine as a bonus. Nothing about the change has been hidden and there's nothing devious going on.
When it comes to selling the car on, the trick is to be open about the engine replacement and highlight it as a bonus about the car when compared to others for sale with older engines in them, the condition of which is unknown.

Thanks for the opinions. I'll probably give this one a miss. No rush
Seems you're in the: "I'd rather gamble on an unknown engine camp". 4rephill said:

My understanding is that direct injection engines were suffering more than most, and the carbon is quote solidhttp://audisrs.com/archive/mrc-tuning-vs.-pippyrip...o_tt_5000.html
