Hi all,
Had the roof stop working on me last week while trying to put it down using the switch in the car. Windows went down, back window went up, trunk unlocked, then nothing. Couldn’t see anything obvious like chafing of wires etc. Was not able to open the trunk lid so I slowly pulled the lid back enough to reach the luggage lid and check for proper seating. Seemed fine. I then pulled the emergency lid release. Poked around and did not see anything obvious. No hydraulic leaks and pump looked fine. No rust. Drove it to the dealer at slow speed.
Dealer says it’s maybe a micro switch. They change that out and are now telling me it’s a hall sensor and the hydro pump. I nearly passed out when they quoted me $4k for the pump unit part. They said the pump seems to be hydro locked. Possibly from me pulling up the trunk. They were not able to release the pressure on one side. This sounds suspicious to me. I could use some expert advice from someone who knows their way around these units. I’m a DIYer, but but I don’t have any data on these pumps. I see lots of hex screws, but don’t know what they do. I feel like it should be possible to drain out all the fluid and unlock it. I guess it could be a solinoid failure. I see three solidnoids on it. Are they testable and replaceable?
I also need a recommendation on a diagnosis tool for BMWs as my scanner is not able to read much. Amy help would be appreciated.
Thanks,
Shawn
