BMW 5 series ongoing problems

Resolved Question:

Hi I have a BMW 5 series, it's 1.5 years old, I have had continuous problems with it, it has been in and out the work shop for investigations, on one occasion for 5 weeks, the stop start would not start the car, they were unable to locate the problem, but changed the clutch? They overfilled the car with oil, 2 months later I got a warning from the computer advising oil level too high. Then I got a warning from the computer saying drive train, continue journey at moderate speed, full performance not available, the car cut out at the traffic lights, I was unable to start it. I got breakdown to come out, he plugged in a diagnostic, it pointed to the fuel pump, when he opened the boot and pulled up the lining to get to the battery and control unit it was almost completely submerged in water! We took pictures and I video recorded it. He said he had never seen anything like it, my question is, just how much damaged has this done, and could this have been the problem along, since I bought the vehical. Any advise would be good, many thank you,

water on the electronics can cause all sorts or bizarre issues, so it is possible that this was your problem all along

 

I am surprised that your garage could not diagnose this.

 

As far as advise, if it was a main dealer doing the work, I would involve BMW customer service and complain and complain and complain to whoever will listen and run the issue up the chain as far as possible. The more you complain, the more likely you are to get something from them.

 

You can also complain to the management chain at the dealer.

 

If it was a non dealer or non certified by BMW garage, then all you can do is complain to the management there.

 

your best bet is if it was a main dealer, to complain to BMW. They don't like it when a customer gets the runaround and poor service like this from a dealer.

Hi Steve,
The car is from a BMW dealer franchise, but we will go to m
BMW direct. What I was looking for was some technical answers of the water damage, I can sent you a video of the boot with the electronics and battery submerged if this helps, so I have some technical info to bat back at them

hi,

 

this is the question you asked:

 

"my question is, just how much damaged has this done, and could this have been the problem along, since I bought the vehical. Any advise would be good, many thank you,"

 

this does not request technical answers. I did my best to answer what was posted

 

what technical answers do you want?

Customer: replied 3 years ago.
What components can it affect? What it could lead to, I am not a mechanic that's why I am seeking advice, as I know when the garage calls me they will try and confuse the situation with technical jargon, and that I should not worry it's all been fixed and parts replaced, I only have 18,000 miles on the clock and look after this car
Expert:  Steve replied 3 years ago.

please post images and the part numbers if possible from the wet items.

 

Customer: replied 3 years ago.
Do you have an email address I can send an attachment to? Or can you tell me how to attach the image on this page
Customer: replied 3 years ago.
Steve, how do I post the images on this site? There is no attachment facility that I can see? Do you have an email address I can send them to?
Expert:  Steve replied 3 years ago.

please list out the part numbers of the wet items here.

 

you can send pictures to support at justanswer.com and reference this question, they will forward them to me

Customer: replied 3 years ago.
Hi Steve, I have contacted customer support, all being well you should have the images shortly
Expert:  Steve replied 3 years ago.
Please also list the part number as I requested.
Customer: replied 3 years ago.
Steve, the car is in the BMW workshop, you will see from the images what has been submerged, the rescue man did not give me a list of part numbers, he just said the whole control unit was fully submerged
Expert:  Steve replied 3 years ago.

I will review the photos when they are relayed to me. In the meantime, it would be very helpful if you can call the garage and ask them to confirm which "control unit" they are referring to and what its part number is.

 

overall, if anything gets wet, it needs to be replaced. And, these cars are very sensitive to voltage fluctuations, so, if the battery electronics were wet, this could very easily cause voltage issues and signal interruptions, which can set off all kinds of random warnings.

Customer: replied 3 years ago.
Hi Steve, can you confirm you have received the images? I also forgot to mention when they serviced the car, they overfilled the engine oil, however the car did not throw up a warning until 14 weeks later! They took the car back in , gave us a courtesy car, returned the car, fully valeted, full tank of fuel, and said it would not cause damage. I have asked for a full print out of all work carried out on the car, lucky I have also kept a log, as they have omitted the engine oil situation, and say it has not been logged that this happened. I have called the garage now twice to establish what parts are being replaced, on both occasions the manager was busy and said he would call back, so far no call. Best regards. Tracy

Relist: Other.It had to send images to Steve, however delay in sending them and my bmw expert is offline now, and I need help just now before going into dealership
Expert:  Steve replied 3 years ago.

the images have not been relayed to me.

 

if you wish, you can try to post the images to a photo sharing site and then post the link to the images here.

 

 

Customer: replied 3 years ago.
Steve, I spoke to justanswer.co.uk, I have emailed them to them, they assured me they would pass them on. What is a photo sharing site?

Expert:  Steve replied 3 years ago.

a photo sharing site is a site where you post images or files to share with friends or to back them up

 

mediafire.com

box.net

picasa

etc

 

Expert:  Steve replied 3 years ago.

I have received your files

 

this does not change my answer

 

any wet modules will need to be replaced

 

if they were wet, they could have easily set off phony warnings since this will cause internal shorts and cause them to sense signals and faults that are not present, and can interrupt power distribution - this in itself can cause other systems to set off phony warnings.

please let me know if you require further information, otherwise please select a positive rating, thank you
