BMW and M Power Owners

Finally got the 5 back and looking like all fixed by a DP *cough* and a remap. Engine must have been choked on the exhaust as well as the intake.

How do you pass MOT with a DPF delete these days? I thought that they now check for smoke?

what's the strategy under the latest MOT then, to avoid smoke signals ... is that a special service from Deutch Tek.

My assumption was the tune would be enough for the emissions as long as they didn't check the dpf was hollow - but no biggy I can get anything MOT'd for £75 if worse comes to worse, they don't even need to see the car :D
 
About bloody time. Hard to believe the i8 & i3 were 6/7 years ago and BMW haven't really tried since then.

What's really interesting is that BMW/Porsche etc. are finally revealing some electric cars, just as Tesla are about to update the S. It would certainly tickle me if someone else finally matches the 2013 Model S in range and power only to get completely floored when Tesla reveal the refresh :cool:
 
My exhaust started blowing this morning around the area that lines up with the front of the door edge, around the area it starts to come under the car. (not that mechanically minded sorry)

You can feel the air leaking out. It's a e92 330i. How much could I be looking at to sort?
 
Take it to a local garage who can weld/patch it up fairly easily if it's a minor leak. A rusted big hole is another matter and may require just that section of piping being replaced. Easy job again for any half decent garage. Not a costly affair either fixing stuff like this.

Labour rates completely depend on garage.
 
Taking my car to Sytner next week, under the AUC warranty. Engine struggles to start (up to 7-8 seconds of the starter motor cranking) and yesterday it gave up during the first try but managed to start the second time.

Still has its original battery, so guessing it's just a battery change.

Doubt it's the battery. The batteries job is to turn over the starter motor which it sounds like it's doing just fine, there will likely be a problem with the fuel or spark element. Could be a bad fuel pump or crank position sensor?

The reason why I suspected battery (and to be honest I'm not very clued up on the workings of an engine, so could well be wrong), is because when I was cleaning the car a few weeks back, I had the engine off, but the radio on, and within 2 minutes I got a low battery warning.

Also, once the engine starts once then it will immediately start after. Only when the car is immobile for a few hours will it again struggle to start.

In any case, in response to your question: I have no idea:p

I've had the car for a month, so BMW will have to sort it out.
 
I do a few runs a month up to Manchester area, I usually get around 42 mpg but I decided to fill it with Super (Tesco Momentum) and I got as high as 46 mpg. Cruise control set to 75 and the car in eco pro mode. A few stops on the way with full throttle joining the motorway and then back into a cruise. Pretty impressive but I'm not sure the extra mpg is worth the price of the fuel. Perhaps more testing required however I'm fairly sure I get around 5 mpg more when using super.

Interesting - I can see why you'd think it was that!

It certainly sounds like your battery needs replacing, but it also sounds like you may have a fuelling issue also. If your battery has enough power to give 7-8 seconds of good cranking and it's not firing, it's not going to be the battery that's causing your starting issue IMO. My E92 had a dodgy battery like yours for months (low battery notification after 30 seconds of having the engine off) but never failed to start or even struggle.

The 330i also had known issues with fuel pumps and injectors AND it's classic symptoms of a failing fuel pump for first starts to be difficult (as the pump has to work hard to bring the fuel pressure up after it drops from being left overnight) and subsequent ones to be fine so this would lend more credibility to a dodgy fuel pump. As the pump deteriorates, you'll also get error codes when you're flooring it as the pump can't keep up with the demand the engine is generating.

Good that you've only had it a month and it's BMWs problem though, let us know how you get on! Don't let them fob you off!

Thank you for the information!

I'm definitely not getting any error codes (or any change in performance) when flooring it though :p.

Will update once I take it in and get an update on what they think is wrong.

I'm going for a MAF/air-leak problem - if you feather the throttle when it's starting does is start better ? (presumably you start with clutch in)
injectors - what petrol have you used ?

be too easy for the garage to replace the battery speculatively if you are paying too
 
I bought a f11 on 11th May and with the warm weather I’ve noticed the AC doesn’t ever cool the car as I would expect. Is it best to take back to bmw or try a regass first? I feel this would have been present when I bought the car, but want to try the avoiding the argument with bmw if possible.

Are there any known issues?
