Hi guys, this is my first post so take it easy on me :)
I have been a member for a while and used bimmerforums amongst others to help me out with many problems ive encountered on my BMW's over the years so I have the chance to return the favour!
I will try to be as descriptive as possible and explain my thinking so its basic without boring you..


My trouble was with my e93 335i 2007... when pulling back the roof button the windows would drop down, you could hear the roof latches disengage, then nothing else would happen and the button would flash red and my I-drive screen would say Roof System! I could push the top front of my roof and it would separate from the windscreen frame so I could tell the latches had definitely disengaged, but the mechanism wouldn't allow the roof to actually move. I would then have to push the button forward to re-engage the locks and secure the roof with no action..

If you are having trouble with your roof going back check that there is nothing in the way in the luggage compartment and that the convertible tray is pulled down and that your battery has sufficient charge before going any further...

I booked my car in to my local dealership to be looked at (£70 for first half hour inspection plus £££ from any time then on, plus parts, plus labour...) and in the meantime scrolled through plenty of threads I felt didn't apply to me searching for an answer. Lots of people are saying give your roof a push and it should help it open DONT do that, try this first before going anywhere. I came across someone with similar symptoms but in reverse.. Their roof was stuck in the boot, the button would let the boot flip open and ready for action but nothing happened. To solve their problem they paid an indy to source it to faulty roof system 'Salmon colour Relays'

I then found out the system uses two relays for the pump - one for the roof down action and one for the roof up action.. I knew the sensors were all fine because the system was allowing the first disengaging actions but not the actual movement of the roof. I couldn't find an actual write up for the resolution on how to do here so here we go:

Convertible car not being very convertible..


pull back roof button, windows go down locks disengage light is green..


then nothing happens and you get red flashing light


I-drive tells you to check roof system make sure nothing is in the boot compartment


proof the roof is unlocked as it will open...


do yourself a favour and buy BOTH new relays (£14 from BMW Part No: B12.63.1.742.690 RELAY known as salmon relay)


Open your boot


pull off your battery trim panel, undo the 10mm nut on your negative terminal (one closest to you) and wrap it up or place it somewhere it wont touch the terminal (I always disconnect the battery when working on electrics just incase), Lift up the boot floor panel and you will see this pentagon shape panel with 3 10MM screws through it, Undo these and lift off the panel


You will then see the convertible roof pump & reservoir etc, and the two salmon coloured relays on the front, just pull the whole unit up for access as it isn't secured down, pop out both the relays and pop your two new ones in..


re-secure the 3 10mm screws through the panel, close the boot floor, reconnect the negative terminal and tighten the 10mm nut, hop in your motor start it up pull back the button and laugh to yourself at how easy it was to fix all that heartache.





difficulty level - 2/10
Time taken - 5 minutes
Total cost - 28 pound

I wont be held responsible for any damage you cause to your vehicle but this really is a simple job and if you are having roof troubles I suggest you try this first.

Hope this is of help to someone out there :thumbsup
thanks - Alex

Haha thanks, I'm quite handy with cars but sometimes following a written description can be hard work. It really is as simple as it looks, but 'touch wood' hopefully you won't have any problems :)

Just wanted to say thanks!

My roof just failed and Specialist Cars wouldn't fix under warranty as they found a small dent on the C-pillar and blamed "customer damage". They wanted £1300 for a new pump, and their body shop apparently said it would be £10k+ to fix my "misaligned roof".

So I found your post today and figured I may as well try the relays... funnily enough I bought them from the same dealer as you (not that I'm ever going back there as this isn't the first issue I've had with them! Awful service!).

...and roof is fixed!!! Thanks so much for posting this. Saved me buying a refurb pump on eBay, which wouldn't have worked anyway!

You are more than welcome! believe me, reading that made me as happy as the day I managed to fix it! its nice to know you've been able to overcome a shed load of stress, aggro and most importantly maybe money! im chuffed for you pal.
Are you in luton too? To be honest ive never experienced the servicing department, I had it booked in with them but I managed to solve it before the car actually went in! ive only ever experienced their parts department which I find the young guys down there are great! I can only imagine I would have been fed the same rubbish as you if my car had actually gone in.
Either way im over the moon for you its fixed (especially for the weather this week!) and glad that posting my experience has actually made a difference to someone! even if you are the only one its worth it :thumbsup:

Hehe I've had it down everyday this week! ;)

The older guy in the parts department wasn't exactly Mr Helpful, but I didn't even bother explaining what I wanted the parts for. The young guys I've dealt with in there before do seem more helpful (just finished an NBT retrofit).

The service team have annoyed me before, mainly due to putting 14 miles on my car when it was in last. Quite some road test. They also only changed one of my throttle valve actuators even though BMW say they should be replaced in pairs? But I wasn't annoyed enough to avoid going back...

If I had paid for a new pump, I wonder if they would have admitted they had to change the relays (or maybe the relays come in their 'kit')?! I'm also annoyed they also said I need a new roof to fix the alignment (I would have had to waive the warranty on the new pump), as I've since read that a special jig exists to re-align them (and it's a specific course for a tech to service the roof). I'm guessing they're just not equipped...

Anyhow appreciate your post!!! Will wave if I see you around Luton ;)

Great link, but didn't work

Hi thanks for taking the trouble for this, I did get quite exited, but unfortunately it didn't work for me, so back to drawing board for me, I did find some (what looks like hydrolic oil) in the battery area, so could be a clue, I will post my findings for others

Big thanks from me too mate had the same problem yesterday where boot lid would lift but roof would not come out. Replaced the bottom relay and voila all sorted. I assume the top relay is for retracting roof and bottom ones is for putting back up.

Thank you thank you thank you for this thread. My roof got stuck down yesterday with the same issues. The boot lid moved but the roof wouldn't budge.

I took the relays out and popped the plastic covers off. They were filthy so I gave the relay contact point a clean and put them back in. Worked like a dream, I dread to think how much BMW would have charged!

I'll be replacing them ASAP, but maybe this tip might help others out and get that roof working again

Top won't come up

I am new to the site, but am appreciative of the good info that you guys are giving out. I have had a problem with my 2009 hard top convertible. The top wouldn't go up, so this is what I did....removed the cover for the hydraulic system that is in the trunk. I noticed that the hydraulic oil was below the + Mark. I simply lifted the hydraulic pump out of its mount, (no attachments, it simply pulls out). I then tilted it sideways so the reservoir was pointing down and loosened the jubilee clamp that holds the reservoir to the pump body. Then I pulled the revevoir away from the pump body and filled it with power steering fluid. Replaced the jubilee clamp, put the unit back in its mount and PRESTO the top was working again. I looked carefully for signs of leakage, but have yet to notice anything. I should mention that I have had a historical problem with the top sometimes having issues going down, and should have checked the oil level at this point. I wasn't until it actually quit working that I had a look at it. Anyway hope this can help someone....keep up the good work

Out of interest how much fluid was in the reservoir. I'm having intermittent problems and the fluid is on line with the plus + sign.

Out of interest is it not special oil or just power steering oil reason I ask is I have just had a new pump fitted and was told there is a days delay as they didn't have the right oil in stock !!!

Intermittent?

Hi,

To all of you who have successfully fixed your e93 roof by replacing the salmon fuses -- was your problem that the roof sometimes wouldn't work (intermittent) or was it that it broke and you never had a successful opening/closing after the breakdown (until the fix)?

I am myself having some intermittent problems with my roof -- most of the time it works well but once in a while it stops half ways for a a few seconds and then continues on. I am trying to figure out what the problem is since BMW couldn't find anything wrong with it. (Of course it worked when they were trying it.)

Holy shheeeyite! I am in the wrong job. 10 thousand pounds. Less thirty quids worth of relays, less mechanics 15 minutes, less tax equals an absolutely amazing profit!

To the original op, nice write up, to everybody else with a convertible - ten thousand pounds!!!!

You just rammed home the fact I am never buying a power operated roof convertible.

Replacing Relays fixed Stalled Harttop Convertible Roof

Hi,

re: Green 2007 328i Hardtop Convertible / European Delivery in June 2007

My first post.

I had the same problem: roof would go thru partial process then stop. After months of inaction, I finally bought 2 salmon relays for $25 USD each.

I had a local BMW mechanic run diagnostics and install relays. He originally suspected something else was wrong. Diagnostics did not show a problem. He replaced the relays and the top works perfectly. He charged $26 USD.

Thanks!

Hello,

Several times my roof stuck down or up and I had to wait, restart car and it would work. This happened 3 or 4 times.

In January the problem became chronic. Car would start the process -- I could hear gears, etc., and roof would disengage from windshield then nothing.

I do have an intermittent problem where the roof will drop into the trunk with enough force to trigger some sensor and stop. I then release the switch and try again. It seems to happen more on hills then flat terrain.

Hope this helps.
