Z4 Recall by BMW

[LordOxygen]

Just read that, how on earth will bmw issue a recall for cars going back to 2007

They use DVLA records to contact all registered owners.

My guess is that this will only apply to E89 Z4s.
Otherwise it doesnt make sense not recalling for anything pre 2007.
If a 2006 E85 isnt affected i dont get why a 2007 would be.

Unless there was a difference between engines installed pre and post 2007, but i dont think there was was there?

There was the black engine cover change from silver, if we want to add more fuel into that fire


Oh rats.
That me potentially back in the s**t bucket then.

Actually you may be OK - I think that may have been a change for the 2007 model year.

My First Coupe was built in October 2006 and had the black cover - my current one was built in August and has the grey one.

Yeah. That was said in jest.
I’m not concerned - pretty confident it will turn out to only be E89s based on what’s being said.
I understand it was an E89 whose lights failed in the states which kicked all this off.

I would get your motor checked out regardless especially if you are watching tonights Watchdog

I think it affects 1 and 3 Series, X1s and Z4s between 2007 and 2011.

Just because your car has been fine doesn't mean it won't be in the future. I had to replace a wiring loom on the Z3 after 13 years as the loom had been chaffing for years, easily a fire risk. There was never a recall but BMW did a replacement loom as they knew about it.

I think they need to be more specific on the models, engine sizes and date ranges affected before we start getting too worried. Government recall checker shows nothing for my 2007 Z4M at present.

I wouldn't worry - they've had some practice!

Last year I got a recall through the post for the driver's airbag on my E46! Just a shame it wasn't done when I took it in the year before for the passenger airbag recall!

Further reading seems to suggest it relates to the B+ battery connector which runs between the fuse box and battery. Could be an expansion of the 2017 recall which listed 2009 onwards cars (e89).

I watched the program last night, it appears to be E9x 3 series and Gen 2 Z4 rather than Gen 1 Z4. But if in doubt contact your dealer with your VIN number.

There were two problems identified on the program:

1. An issue with fires caused by a heater control, the problem was described as being associated with the plating on the terminals on a heating control ECU and the fix is to replace the module with a newer version that changes from Tin to Silver plated terminal (having said that I couldn't find the offending eCU in real OEM). Apparently BMW have done a recall on this in the states.
2. A problem with a main battery feed to the fusebox overheating which can lead to a fire. They showed the feed on the program and it was a blade terminal. I have to say I am very surprised at this, I have been designing vehicle electrical system since 1986 and I would not use blade terminals for a fusebox feed. I recently analysed an E85 fusebox on a bench and from memory it uses the more common ring terminals for main feeds.

I am concerned though as I just bought a 2011 E91 for the wife and I am far from happy if the fusebox feed shown last night is on my wifes car. Even more so because I struggle to see how BMW will retro fix it IMHO it needs a redesign. I suspect the recall will be an inspection job, to view the cable/fusebox for signs of overheating. If not they may leave alone.

well going off the bellow

https://www.bmw.co.uk/help/ownership/recall-bmw-battery

"BMW is expanding an existing B+ battery connector UK recall. This relates to predecessor generations of the 1 Series, 3 Series, Z4 and X1 built between March 2007 and September 2011."

Mines 2007 August production date, which is between them dates, but the local dealer said its not on the list but they will book it in FOC for it checking to see if it requires doing.

you can email them on [email protected]

I read that fixing that electrical connector is a 90 minute job so not a quick fix. Multiply that by 300000 and it will tie up dealerships for ages. Dont think I would want to use a car knowing the extent of the problem before it gets fixed. But looking on the bright side they wont have enough time to charge owners thousands to change their oil!!.

[Magicarcher]

For those interested there are a couple of youtube posts that show the problem relating to the recall. The issue is with the main fusebox B+ feed which uses a 90 deg blade terminal, the terminals are basically going high resistance, BMW solution I believe it to replace the standard terminal with a silver plated one (I do hope they are changing the FB and the cable!)

Very different to the E85 that uses a nice meaty ring terminal with threadlock nut for the main supply:

I emailed BMW, my 2008 E86 is affected by this and needs to go in.

I think they may be mistaken completely different design of fuse box to the E89.

I am sure they are, if you look at the post 3 up it confirms the E85 (and presumably E86) use a bolted ring terminal for B+ which is entirely different to the balde connector in the offending B+ cable on the E90. It will be interesting to see if BMW accepts their claim for the investigation time.

My November 2007 E86 is not on the list according to my local BMW stealer.
