    New bloke with E12 M535i

    After fitting a new distributor cap and rotor, along with a new cable which links the ignition coil to the distributor, my car sadly wont start. It sounds as normal when trying to turnover, but it just wont spark into action. I've turned my attention to testing the ignition coil, and just wondered if anyone knows what the readings should be? The primary resistance readings range from 1.2 to 2 ohms The secondary resistance is consistent at 5,190 ohms I've tried to search for a new coil online with limited success, as was hoping to find further details. Does anyone know if these readings look ok? Thanks

    Thanks Joe, that's great and it was that part number I'd searched for. What was confusing me is that on the list of part numbers, it shows Rotor rev limiting 1211304909 And also rotor Non rev limiting 12111360306 I just wasnt sure which one. Thanks again for your help Pat

    Hi, does anyone know where i can get the correct rotor arm part from please? I have ordered a new distributor cap and going to replace the rotor as well, but the part number isn't clear as some websites seem to state different numbers? Has anyone replaced their rotor arm recently? Thanks

    Thanks Tim I have ordered the cable which connects the coil to the distributor so hoping that will help. If you do have any leads and a cap please let me know as I may well be interested in them depending on what difference the cable makes. I have noticed a bit of rusting on the rotor aswell, so will clean that up too to see if it helps. The last resort would be to replace the distributor itself, but hoping to avoid that. Jess, if you have any hints / tips / advice / pictures that you think would help that would be brilliant. Many thanks Pat

    Hi Mick Thanks for your response, much appreciated and very useful. The piece that is broken is the connector at the end of the cable that connects into the distributor cap. Based on the diagram the parts I'm looking at are 2, which is the wire which I have, 7 the suppression socket and circular connector which are both intact, and connect to the coil, so I'm thinking i just need number 6. However, when I've searched the part it doesn't look like what was previously connected? If anyone has a picture from there own e12 m535i that would really help, as I'm not sure now if the previous part used was correct? Thanks

    Hi, I'm really hoping someone can help. I have had issues with my e12 m535i not running correctly, it stutters when idling and misses sometimes when accelerating. I initially thought it was a problem with the AFM, but having replaced that the issues remain. After further research it led me to start looking at the distributor, thinking there could be a fault there. When checking this, the middle input to the distributor seemed loose, and when inspecting the cable the end piece has completely broken. Its obviously been bent by someone in the past, which made it weak and it has now broken. I therefore need to replace either just the end piece if possible, or the whole cable. Does anyone know where I could get these parts from? I'm new to all of this so any help would be greatly appreciated. Many thanks Pat

    Hi Tim Thanks for your message. Its 0 280 203002. I have managed to source a replacement which I'm told was in working order when it was removed from its vehicle around 30 years ago!? Once I've fitted it I'll let you know if it solves the problem. Fingers crossed

    A very belated thank you to Tim Pollock for helping me get my calipers repaired. Very knowledgeable and a top guy. My next task is to replace the air flow meter. The car intermittently misses / stutters, which I've been told might be due to a fault in the air flow meter. If anyone has ever had a similar problem any advice / comments would be very much appreciated.

    You'd think so!

    That was my plan, but the bolts are also too long as they are not threaded all the way up.

    Hi Tim The spacers are 15mm at the moment, which takes the width to 30mm. Thanks

    Hi I just wanted to introduce myself to the group. I own an 1980 e12 m535i and have been reading this thread with interest. I live in the UK (Derbyshire) I currently have a big issue trying to get my front brakes sorted. As you'll know the calipers aren't available anymore and in order to get mine restored I need to fit reduced spacers in them, but I can't find them anywhere, or any calipers I can take them from.

    Hi, thanks for your post. The spec is 280mm x 28mm, but these discs just aren't available anymore for the e12 m535i. In order to reduce calipers to the 25mm thickness, I need to change the spacers (currently 15mm) for smaller ones, to fit with the 25mm discs. The width without the spacers is 15mm so the spacers would need to be around 10 / 11 / 12mm. I believe the e23 7 series calipers may have the correct spacers, but they are not directly compatible as the e12 m535i doesn't have abs. It's very frustrating
  14. Hi there, is there anyone on here who knows about the front calipers / spacers etc that could help me please. My calipers have previously been upgraded to allow for the thicker 28mm alpina discs which are no longer available. Therefore I am trying to revert back to the standard 25mm discs, but I need to reduce my spacers. Any help would be appreciated as I'm going round in circles! Many thanks
