Just preparing here in case they don't do what I ask.

Long story short my bmw smokes upon hard acceleration, I put it into one dealer under warranty, they apparently replaced the dpf and pressure sensor - probably cleaned it but receipt said replace.

Fast forward a month or so, a friend tells me my car still smokes but this time it's put a fault on, those were read and it points to Egr and dpf!.

Dealer rang up and said they see going to replace sensor (I know it will still smoke or will quickly down the line), I explained they've tried this before and I don't want to be down this path again in 2 months out of pocket because it costs me money taking the time to put the car plus the inconvenience and it's hot good enough, dealer data they can't just replace bits because bmw won't pay for it.

I think it's Egr/dpf related, the Egr causing excess smoke and taking out sensor and dpf and they need to replace both of these. I want both these items replaced as i think the root cause is the Egr and then we've tried this avenue, only to thus time it put code on.

How do I play this? It's only 2.5 years old car and under full bmw warranty.

I'm away and have courtesy car I'll have to spend another 2.5 hrs unpaid to collect.

Thanks

 

the EGR on our old diesel used to get caked up and make the car run like shit and use loads of diesel but that was when the missus drove like miss daisy which i doubt you do

and the DPF is a filter right? they just clog up don't they?

is the car remapped?

 

They will play games for half a year then boom you are out of warranty. Invoke BMW head office ASAP.

 

Pain in the backside those DPF's - i've heard many times the BMW's ones are particularly sensitive/throw faults, however on the slightly older 2.0d/3.0d's
There's a place in Crewe that will remove them permanently with your remap, but they make it look like your car has one still fitted - cheat?

You might only have an injector fault that's beginning to surface now with the smoking rear end, but strangely it could read a different code (seen that one before also).

 

This with bells on. BMW's customer care is appallingly bad from my personal experience. To the point where I don't think I could own a BMW again.

 

Make sure you have documented evidence of it being an ongoing problem within the warranty period.
I'm not sure if it is legally binding but it gives you a lot of leverage to get them to continue dealing with it at least as good will outside the warranty period

common sense. Be aware American so not likely reflective of uk legal law and caught my eye because he is talking toyota language that means I caught onto it quickly

 

EGR stuck open?
Try blanking it and see if the smog clean up.
If not you may have a leaky turbo seal...
