Think I'm unlikely

Post by Tez123d » Thu Apr 19, 2018 7:09 am

So took my 123d 2008 to the dyno yesterday to get a remap (used pk automotive as they are on my doorstep)
Received a call from them and the car only has 141hp .

After a day of mapping they've got the car up to 214hp but the owner didn't want to take it any more due to a ticking sound between 1000rpm and 2000rpm the sound can also be heard when the engine winds down after been turned off.
He suspects possible timing chain even though the man at soper bmw said my car wouldn't have a issue.

It gets even better after the map my car has a management light on that relates to egr valve so it sounds like that's gone again (I say again as it was replaced with a second hand unit by the shop that I bought the car from 3 months ago)

And this is where it really takes the p*ss now, so after getting loads of crap news on the drive home I manage to clip a pothole and blew out the tyre and knackered my wheel too.

What have I done wrong in a previous life

Sorry to here about all your woes mate...but that's three bad things...it comes in threes...so all good from now on.

Seriously though, I wouldn't have had mapped. I would have taken it somewhere where they could.

1.check the map is the original one from bmw.

2. Find out why it's not making the power and fix it properly.

3. Confirm the ticking noise.

4. Then have a remap.

I hope you work it all out. Sorry I couldn't have been I'd more help.i may be wrong but I don't think a dodgy egr could make your car lose that much power. Must be something else wrong.

That's what I'm thinking once the wheel and tyre is fixed then I'm going to be sending it back to them and leaving it until I get a propper car back

How many miles has it done.??...it really does sound like the timing chain is going to need doing at some point and it doesnt need to be coming out of your pocket.. they said it would be fine...but if it's already making a noise...then they are 100% wrong.

So sorry, that's a whole stack of woes...but at least you know that there are problems and you can get them rectified.

Did you buy it from Soper BMW? Probably not - your car might be a bit old for a main dealer. In any case, they know very well that the timing chain & tensioner design has been updated several times, the last time (I was told recently) was in 2014. All of the early N47s are at risk, even if they have had the chain replaced - the replacements can go the same way as the originals.

Act quickly, put your findings/car issues in writing to the supplying dealer, even if they are accepting the car back for repair, confirm in writing the reasons for you returning the car, with the dates that any faults were identified. Make sure all the faults are documented, including the previous EGR fault/repair. (Actually, you can't have bought the car from a BMW dealership, they would never admist to having fitted used parts).

It's probably a good idea to record the noise from the motor and tell them that you have been warned that the noise is likely to be the timing chain. Make it clear that you have had an independent opinion...and it might be worthwhile getting a report. If it is the timing chain, there is no way to mask the noise once it's started.

Good luck.

Very good advice...ive heard that if you put some 5w40 in when servicing it can make the chain quieter as its thicker oil...i use this in mine.

If you did do that and it made it quieter, at least you have confirmed it's the chain...just an idea but what toed said above is the correct steps to follow..

Thank you all for the advice tomorrow ill be calling the company I got the car from and that did the initial repair when replacing the egr and intake manifold.

I've had a talk with a indipendent bmw specialist here in Lincoln and he's asked that once I get the tyre and wheel sorted if he can take a look as his description of the timing chain is "it makes a noise like a train coming past you" and thankfully it doesn't sound like that yet.

He's also advised me to contact bmw UK if the chain is the issue as some dealerships might not be overly interested as they are just franchises.

Will keep everyone upto date on how it goes and hopefully I'll fall back in love once it's sorted

Just spoke to the suppling garage and they claim as the car has been on a dyno that has caused the egr to fail

How true does this sound

I suppose bmw wouldn't put it on a dyno to check power and possible issues as it would mess up the egr? Mmmm

...although it is possible that your mapper messed about with the EGR coding and got it wrong...I would have had it coded shut.

The EGR fault is relatively minor though. I'd suggest that you call the mapper and ask if he/she changed any parameters of the EGR coding. If not, your dealership is waffling to wriggle out of their liability. If they did not comment about the mapping and only talked about the rolling road, you might ask them how they would compare risk of damage to the EGR in normal use (during a few heavy/hard WOT pulls) to that posed by the time on the rolling road. I'm not at all sure that they can say that the rolling road would put more strain on the car's components.

Good luck.

Hopefully this is a bit of good news got the warranty company involved now and they have told me to book the car into Halfords auto center to get diagnosed and repaired.

It's going in next Saturday so hopefully get some good news.

Spoke to pk automotive that dyno ran the car and he said once its fixed he will map it and then map the egr to be closed too.

Finally I'm not feeling so fed up with the car now

So car went into Halfords today and just received a call and the management light is being caused not by the egr valve but so the bloke from halfords says its a aux water pump.
The noise from the motor is alternator belt so they say and how the decided on that is just by replacing it.

The very odd thing is they say all 4 injector seals are leaking. This could be the reason for the diesel smell I noticed

Will keep everything updated as I find out more
