Im sure someone on here a few years ago had issues with the paint on one of the roof panels, cant remember the outcome but it went along the lines of the garage knocking back the claim under the excuse that the roof didnt come under part of the bodywork.Gwest44 said:Good idea this when you listen to the story that the staff at Sytner recounted to me on collection of mine this week - it is lengthy so bare with me.Pondrew said:Gwest44 said:I think they made some reference to it being due to the paint not bonding properly but to be honest I can't recall the detail.
What I do remember is them saying the warranty is not valid if the paintwork fails their original paint test or if the corrosion is found to be due to a stone chip or similar impact.
They also said they love this type of work and welcome any customer who brings in their car for assessment - obviously BMW pay top money to Sytner no questions asked.
It might be an idea to start a list of these on here and ask the management to pin it under E89 problems. If this is a common fault which starts occurring on many 10 year old plus E89s, I can see BMW not wanting to replace thousands of roof panels and trying to wriggle out of claims, or just doing a quick sand and respray.
If we have a list and possibly get numbers of affected vehicles to date from BMW UK under freedom of information act any claims going forward will have more weight behind them with data from the "owner's club"?
A few years ago they started getting a lot of 3 & 5 series cars coming in for a warranty repair on the headlight washer jets. The issue was down to the feeder pipe freezing and an inability to deactivate the washers. So when the windscreen was washed the headlight washer activated but due to the frozen pipe couldn't retract back in the bumper and subsequently broke. Sytner were repairing loads under warranty at a cost to BMW of £150 a corner - doesn't sound much but they were doing loads. Anyway BMW didn't like this and tasked someone with finding a solution to their problem. Enter the analysts - they found that they were selling hardly any BMW screenwash through their associated dealerships. As a result they introduced the need to evidence receipts for genuine BMW screenwash to qualify for the warranty - if this wasn't possible they claimed the after market product didn't offer the same protection to freezing and hence the warranty was invalid. Apparently almost overnight this resulted in the cessation of all the associated warranty repair work.
Can't help but think they have someone working feverishly to defend all the Z4 roof panel claims so get in quick while you still can.

Like I said I cant remember the outcome but they were trying to wiggle out of the claim and this was the excuse.SV8Predator said:Nictrix said:the garage knocking back the claim under the excuse that the roof didnt come under part of the bodywork.
Well that obviously not the case as evidenced by the posts above!
Lots going on and dont need the hassle, plus I currently have a working roofPondrew said:It definitely won't get better!

The first picture does show wearing of the paint; however I would be more inclined towards rubbing from a manufacturing fault with one or other panel or a bad paint job than dirt. The second two (It's difficult to work out where they are) are clearly the "usual" corrosion from underneath tracking up onto the panel and lifting the paint. I can't understand how different dealers are coming up with different decisions for the same issue, unless some are not following it through properly with BMW UK.Mojito said:However it's NOT over yet. As my photo shows there is also a small area of corrosion on the other roof panel and the underside of that panel has absolutely no wear. No explanation has been given for that so far, so I'm pursuing. I will update when I know more.
Struggling to see how they can reject your claim when the issue is clearly identical to mine which Sytner aceppted without issue.Mojito said:.... and my claim has been REJECTED![]()
Took my Z, which is six years old, in for roof corrosion inspection two weeks ago and Ocean BMW came back today to say that my claim has been rejected. Attached three photographs below showing the usual 'worm like' corrosion and underside of the panel in this area. I haven't spoken to the dealer yet, but he left me a message saying that on the underside of the roof panel near to the largest area of corrosion the paint is worn down to the primer in a small thin 'strip' - see top photo. This has caused damp to track round underneath the laquer and caused the corrosion. The very small worn down 'strip' closes against the rubber roof seal and is apparently likely to have been caused by dirt rubbing as the car flexes. The corrosion is therefore down to me![]()

Interesting that they are saying it's up to the dealer workshop. Mine was checked with Ocean Plymouth and went straight to BMW from them for authorisation, at least that is my understandingMojito said:Update:
My dealer Ocean Falmouth has advised that both their Bodyshop and Workshop Controller have said it is not a warranty issue and this has also been confirmed by their Area technical manager who makes their final decision. The only way forward if I wish to peruse this issue is to log a complaint with BMW Customer services.
I am in the process of logging a very detailed complaint and request for reappraisal of my claim. Not a happy man![]()
I'd go elsewhere to get it assessed - is there a Sytner dealership near you?Mojito said:Update:
