From Whence do Potential Issues Emanate on the 35i and 35is (That is should there be any)?

[Z4MAD]

Dear Comrades,

Having a few moments ago perused a thread created by BIgWinn it would appear that the poor chap, having recently invested in the acquisition of his machine, appears to have been extremely unfortunate concerning the problems he has experienced.

It is the sad experience of the aforementioned gentleman that caused me to make enquiries in regards to potential issues that custodians past and present of the 35i and 35is may have experienced.

With kind regards,

MAD

These are well documented in the following post called - E89 Comprehensive problem list - the link is below

To the best of my knowledge, Stuart has never owned an E89?
The E85s he collects on a regular basis come with known issues that satisfy his hobby of repairing and saving another Z4.
The only reason I would class him as a 'poor chap' is because he's currently run out of space to get another one. :rofl:

Top of the morning

Nope not me!

I've had 4 E85's which have all been a very enjoyable and involving experience to work on and drive!

Shout up if you want any guidance on that or old E30's- I'm your man!

When I bought my Dec 2009 z35i DCT last November seller provided a printout from dealer of work done on the car this is a summary

May be of interest to MAD and other buyers
Date Mileage Work done
06.2011 8313 Replace rear vent
10.2012 13104 Shift quality in “D” downshift double clutch DKG too rough
07.2013 15021 Control unit electronic damper control EDC short circuit note unit replaced
05.2016 37461 Wiring harness roof module,(retractable hardtop) interruption
04.2017 51360 E*x(RHD petrol engine)positive battery terminal line repair cable
04.2017 52365 Both front shock absorbers serious fluid leak -note both replaced (EDC)
07.2017 56790 Drive cylinder, rear module RHT(retractable hardtop). Permanent failure
04.2020 68686 (main)electric coolant pump. Permanent malfunction
06.2020 70272 Cylinder head cover gasket leaking
“ “ Fuel injector. Permanent malfunction- note all replaced
“ “ Rear spring broken

In my ownership
06.21 73764 Cylinder head cover gasket (again)
Leak from oil filter mounting
Fuel pump replaced

Also done under BMW 12 year corrosion guarantee
Both roof panels resprayed for "corrosion" on corners of panels (apparently caused by contamination under paint when new

Car still has a low speed whistle between 1700- 2000 revs which Sytners claim not to be able to hear (has got better since last service and lumpy idle has improved dramatically-spark plugs change maybe?)
Warranty still in place so June 21 repairs cost me excess of £250 only

What list doesn't tell you is of how poor dealer service is after roof repairs car went back 3 times as roof stopped working and when changing oil filter gasket 2 coolant pipe O seals nicked resulting in coolant over my garage floor and car having to be relayed back to Sytners. Only a couple of weeks since major 4year service and apart from low speed whine car now getting to be what it should be like and no more roof anxiety is it going to go up when it rains.

Dear Comrade 2k35is,

Thank you so much for taking the trouble to place your post detailing the issues you have experienced with your 35is.

It also was more than interesting to learn of your experience concerning the poor service you have experienced at your BMW dealership.

Thank you again.

With kind regards,

MAD

The sump on the DCT leaking is a regular occurence, its plastic/resin and deforms over time, once it leaks you will need a sump, gaskets, filters and oil, not too cheap

 

[Z4MAD]

Dear Comrade MCBUTLER,

Thank you for taking such care in placing your post concerning the issues you have experienced,... all of which is greatly appreciated.

The electronic water pump can fail, see my previous post

[Z4MAD]

Dear Comrade Smartbear,

Thank you for advising me of the issue with the electronic water pump. Indeed, I had no idea the water pump was electrically powered, this is something that previously I have never heard of.

The aforementioned leads me to another question which is:

I have observed that the 35is has an Oil Temperature Gauge but I am unaware of an 'Coolant Temperature Gauge'. May I be advised, please, whether there is an alarm that sounds immediately the electronic water pump breaks-down thus to alert the piloti of this extremely serious issue?

With kind regards,

MAD

 

[Mr Tidy]

I don't think they have a water temperature gauge, just the oil one.

Neither did my E91 325i. When the electric water pump died on that I got an amber warning light on the dash cluster then less than a mile later it changed to red, so it was time for the RAC! To be fair the car had done 135K miles.

I imagine the E89s would have something similar.

 

[Pondrew]

Yes they have an warning icon for water temp. They have an oil temp gauge but no dipstick. Your oil level is monitored by mysterious forces only.
The Germans think of everything. They even have an icon to remind you to buy a car lift:

 

[Z4MAD]

Dear Comrade Pondrew,

No dip-stick? What a pity as I do so enjoy checking the oil level, water level and other aspects. And yes, I even check the tyre pressures.

Is there a warning light for the failure of the warning light should it fail to indicate a low level of oil.

With kind regards,

MAD

 

[Pondrew]

Is there a warning light for the failure of the warning light should it fail to indicate a low level of oil.

There is an audible warning of that. It's a grinding noise followed by the car slowing to a stop with a visible puff of smoke (just for clarity) . I told you the Germans were clever.

 

[Z4MAD]

Dear Comrade,

Perhaps a decade or so ago I had an wretched experience with a twelve cylinder engine in which the gasket betwixt the engine and the transmission beneath failed, leaving the content of the cooling system to drain away. There was absolutely no indication of this by way of a warning light but for some reason and I know not why, I glanced at the the water temperature gauge which was on ZERO. There was no sign whatsoever of overheating. I was but two miles from my home to which, with heart in mouth, I made a more then gentle return. That was a really frightening experience. By mere good fortune, no damage was done.

With kind regards,

MAD
