Hi Datatek If you could let me know costs taxes etc as I believe you're over seas? I will transfer money to you. Many thanks

Morning Anyone out there know where I can get an EAS diagnostic cable for 1994 RRC LSE ? Datatek suggested RSW. However they don’t supply them anymore. many thanks

Thanks again Datatek Yesterday I ran the compressor manually and installed a gauge in port 6 of valve block. Pressure rose to 10 bar in about 8 mins and held for over an hour. However the car didn’t rise ? I thought it would have? Just a click noise every 2 seconds.

Thanks for the info. Will this kit work on a 1994 classic? I believe that the system is almost identical to the P38 (in fact we have a 4.6 HSE 2001 on coil springs) I’m wondering if I could try the ECU and other parts as the system is still on the car apart from the air bags I’ll look into this...

Thanks Datatek I think we have exchanged info on here before? This morning I’ve charged the battery and still no compressor. I don’t have the EAS diagnostics unfortunately I can see the connection for it though. I’ve never seen a connection like that for diagnostics. I’ve got the”absolute...

Good morning all. My 1994 RRC LSE has developed anothe EAS problem. I overhauled the valve block and compressor last year. I also had to replace the ECU as the compressor would not run there was no output at pin 8 for compressor relay. Anyway went to the car yesterday and it was on its bump...

Thanks for the feedback Datatek. I'll check the bulbs. Cheers

Morning My 1995 RRC LSE 4.2 air bag light has come on. I have had the instrument cluster out to replace some bulbs so maybe thats caused the air bag light to trigger. Anyone any ideas on how to turn it off? TIA

Agreed. Strange thing is with my old MFU the interior lights only work from drivers door if at all. EAS will operate with doors open. However it will go into diag mode and beeps from all doors etc? The donor unit everything seems to work as it should be no diag mode. I'm going to take your...

Hi Disco1BFG. Your opening line made me think..."wiper will not work with door open" .......guess what I closed the door and it worked LOL.....I feel a right bird brain.... Once again thanks for your help we got there in the end. Can't seem to get it to work in diag mode though, but not bothered...

Yes. I see the rear wiper SW sends a feed to the MFU on pin 16 C205. I think the MFU is then spposed to ground the relay pin 85 from pin 23 C205 Blue/Orange wire. Have If I understood the schematic correctly.... So this is what made me comdemn the MFU.... u

Yes the self diagnosis with HRW sw worked on original MFU, not tried the donor one yet. Also I put a fused ground cable to the relay coil behind L/H foot well panel and wiper works. I've pin tested all connections on the C205 black connector all seen good

Many thanks for the very useful feedback Disco1BFG. TBH my main and still outstanding issue was no rear wiper operation. Washer works but no wiper. Looking at the RAVE schematic the MFU supplies the rear wiper relay coil a ground to activate the relay. All my wiring is fine apart from this...

Happy New Year to all. Anybody know if you can still buy a RR Classic (1994 LSE 4.2) MFU? I have a few issues with interior lights and rear bidet working intermittently and alarm going off. I've tried 2 secondhand ones and they cure one issue but also add new ones. So I'm sure the MFU is faulty...

Thanks again Datatek I’m on it today so I’ll update the post later.. I’ll pin out the transfer box connectors to the transfer motor and see what I get. And remembering NOT to 12v probe anything

I also looked at the WSM vol 2. This is where in the system function section it mentions this 5V control voltage from transfer box ECU. To control the hi/low positioning motor. Any way I’ll fit the replacement and see what happens. many thanks again. I see you’re into P38 EAS?? Mines been...

Many thanks as always Datatek I’ve probed terminals 7 and 8 at C0683 orange and yellow on motor and RS/RP at C1319. The motor worked both ways by swapping probe over then it stopped? So I read some of the WSM vol 2 which implies the system is run on 5V signals from transfer box ECU. So I was...

Am I right in thinking this transfer motor system works on only 5 volts?? As I’ve probed my old unit with 12 volts. It worked a couple of times the went dead. I can probe with of the yellow of orange wire and nothing? They seem think wires to be only running on 5 volts unless I’ve interpreted...

Yeah Second hand I guess. I’ll get one for £45 and make a good unit out of the two if necessary. I must admit compared to a 1995 LSE I’ve got the difference in quality between vehicles is like day and night. You can tell the superior BMW DNA In the build quality. I was a technician at BMW from...

Mmmm the conundrum now is buy a second hand replacement at £35-£140 or buy new at circa £450
