Hi all. Wish someone had warned me that BMW can't guarantee that their cars are water tight. Just posted the following tale of woe on the comprehensive faults thread but I am also looking for some advice on how I might pursue a complaint against the dealer for replacing a part I don't believe needed to be replaced.
1. E89 sDrive 23i
2. 2010/60
3. White
4. Red
2016 (May)
5a. Roof opened half way and then stopped and would neither open or close.
5d. Resolved (but not to my satisfaction – see below)
5c. Total bill/cost to me £2038 New hydraulic unit and wiring/hydraulic line harness. New boot seal and vents.
5d. Problem caused by water ingress through boot seals. First video from service department showed external corrosion of hydraulic unit and severe corrosion of an electrical connector block. Second video showed that hydraulic unit had been replaced and explained that the connector was not available separately and would require the supply of a complete wiring/hydraulic harness in order to obtain the connector to splice into my harness. I asked for the replaced items to be returned to me. On checking the hydro unit it certainly showed some external corrosion but on removing the outer cover of the motor it was obvious that there had been no significant water ingress and on connecting a power supply the motor worked perfectly. It is obvious that they could not have tested the unit as they had already replaced it before repairing the corroded connector. I am really annoyed that they have replaced a very expensive part without checking if it was serviceable or not. I spoke to the Service Manager who, when he realised they had replaced the part without testing the old one, fobbed me off with “it's our experience that they fail eventually if they have come into contact with water” ignoring the pictures I sent him showing that no water had got into the unit.
