Autodim mirror and rain sensor
Dear All,
just looking for a bit of advice from all you gurus out there. I have two 75's at the moment and want to swap the autodim and rain sensor off my old 52 connie SE on to the newer 54 reg connie, which has different option bits fitted. I have seen the various very helpful posts, but failed on the first bit, getting the autodim mirror assembly off. Mind, it was in the dark, so I could not see the screws which hold the cowling on. Are there any decent photos on the forum that might help? Also, if I try to get the rain sensors working do I need the wiper stalk off the old 75? My reading of the advice on the forum was that the T4 needs to be used to tell the BCU that a rain sensor was fitted and this changed the operation of the standard stalk. Does anybody know if this is correct, or am I as wrong as I usually find myself to be? Best to ask first, unlike the last time when the good people on this forum pulled me out of the hole I was engaged in excavating! Best wishes to all, Frank B |

at the two side edges pressed home are two clips that pull out, you can then remove the sensor electronics. The bit stuck to the screen is stuck like ? to a blanket and is quite hard to remove.
I seem to recall asking about rain sensing and you lose I think some of the functionality of the wipers as they are now. Possibly the auto stop when you stop. macafee2 |

You going to cut a hole in the screen trim for the sensor.
I watched one being done, and the ECU had to be taken out, wether it was swapped or not I cant remember.

I don't know about that, but you do lose the wipe delay - it becomes the auto wipe sensitivity adjustment.

I wrote a How To in the relevant section detailing how to retrofit the rain sensing wipers into a car with a standard windscreen.
Basically, once it has been enabled by T4 after fitting everything, you need to move the wiper stalk up on click to the intermittent setting. The car will then use the ECU for its information on triggering the wipe function and the frequency. |

I retrofitted rain sensor wipers but to be honest, wish I hadn't bothered. In some situations it is at best, hit and miss (no pun intended) and prefer to do a manual wipe. Auto dimming mirror on the other hand, is fantastic and I'm going to need another one for my Cowley car.

Developments - rain sensor and autodim mirror
Dear All,
I see there have been many discussions on this subject. I said I would add a post if there were any merit in doing so and it is as usual, both an observation or two and a question or two, the answers to which, might aid others. I used the helpful posts of the rover 75 brethren to get to stage one and changed my non- autodim mirror for the autodim off the old car. Simple, apart from the force needed to remove the old mirror. If I was worried about the screen, I would have chickened out! Then, to remove the old rain sensor. I noted that a "cheesewire" was quoted as being the tool of choice to saw through the pad attaching the sensor assembly. Lacking a cheesewire (and the the manual dexterity to assure I did not damage the plastic window of the sensor) I used 0.3mm diameter nylon fishing line. It snagged and broke as I sawed away. I then lubricated the line with a silicone oil (I expect fairy liquid would work, stopping the adhesive gel sticking to the line) this worked fine. I looked for rover 75 sensor adhesive pads to stick it on my screen, but this search was not conclusive. The good news is, the item appears to be a BMW E series standard item, often referred to as a "purple" sensor, with an adhesive pad of 55x33mm. Fine and dandy, but then how to clean the old adhesive off the sensor? So far, no answer to that, but if anyone has any suggestions, when I get back from working away (last three weeks, hence the slow progress) I would be grateful. Best wishes, Frank B |

The adhesive pads you need are here on the previous page:
https://www.the75andztclub.co.uk/for...0&postcount=15 Best thing to remove the adhesive is a good Tar & Glue remover and/or fingernail, a rather delicate and laborious task but nontheless effective. |

Careful scraping with a knife blade lubricated with WD40 or similar will probably work, then getting the WD40 off is easy with a soapy cloth.
