E30 Zone

I replaced my one back in May 2019. Cheapest place I found then was https://www.leebmann24.de/. Part number 64111375754. This is for the brown blower resistor.

Thanks Brianmoooore. So hopefully head gasket and a head skim and it should be OK. Would there be any chance of bent valves, etc? Given there would have been water in the cylinders when the car was started. After starting the engine when I checked the coolant bottle it was completely empty. It had b...

Well the saga continues. I took the car to a local garage who said it was a blocked radiator causing the overheating. New rad and water pump fitted and car was running fine. Flushed the coolant again. Took the car for a couple of runs and it was running fine. Not overheating, temperature gauge sitti...

boxclever have you worked through the zones no start checklist:

It's a good place to start.

Yes, 12141720856 looks right. Are you going to the dealer to get one?

Hi BristolE30,

Short answer = No.

There was no other branding on it apart from BMW. It is an all metal sensor like the original one that I took off. The Meat & Doris sensors had a plastic body and just a small metal pin in the middle of the end of the sensor that points to the crank .

After the hassle I had with the CPS on my 325 I'd recommend going to BMW and getting the OEM part. I tried two Meat & Doria CPS and neither worked. New one from BMW and 1st turn of the key and she started.

Thanks Brian.

Any ideas what else to check? Would the best starting place be to get the local garage to do a compression test & sniff test to rule out the head & gasket before looking at changing anything else?

The saga continues. After bleeding with the car on axle stands I took the car for a run today. All was going well. Came up to temperature and held at 1/4 for a bit. After about 10 minutes gauge started to rise and got to about 3/4 so shut off. When I checked coolant had been coming out the expansion...

Have you tried realeom?

Have you tried a spark plug connected to the lead from the king pin of the coil? Connect a spark plug to the distributor end of the lead from the king pin of the coil and lay the spark plug on the rocker cover. Try and start the car and see if you get a spark. If yes, then the issue is with the dist...

Thanks linke30.

Heater matrix is linked out as there is a hole in it (another job I need to get to).

Temperature sensor is just approx. 18 months old as I replaced the blue and brown sensors at the same time. I'll look into a new cap. Also wondering if the pump may be on the way out.

So yesterday I jacked up the front of the car and put it on axle stands. Removed the expansion bottle cap then did the following: 1. Squeezed the rubber hoses till no more air bubbles coming up in the expansion tank 2. Removed the small hose from the top of the radiator (the one that goes to the top...

Update 14/02: New thermostat arrived Friday. Fitted it Friday afternoon, topped up the coolant and bleed the system. Ticking over temperature went up to about 3/4. Bleed again and temperature stayed at about 1/2. Saturday morning there was pressure on the expansion bottle. As I took the lid off the ...

For OEM CPS I went to BMW dealer. The part didn't have a manufacturer name on it.

When I had the problems with my 325 not starting I had the following symptoms: With a spark plug connected to the king post of the coil when I turned the key to position 2 I would give a single spark. When all connected back up and trying to start the car the fuel pump would run but no spark at the ...

Hi Brian, Small pipe from rad to coolant bottle is clear. I checked that when I did the flush. When I squeeze the hose that goes to the top of the rad with the cap off the coolant bottle water comes out the small pipe. New thermostat ordered and will arrive later in then week. When fitted and the sy...

Thanks BristolE30. Before this started the temperature would run just below half. The heater matrix is linked out (two rubber hoses are linked together) as there is a hole in it. I did make sure the two hoses were as full as possible before joining them back together. It might be my imagination but ...

Hi Zoners, I have a cooling system query / question for you. I thought I had a small coolant leak so I thought I'd use Radweld as a temporary fix. I then read that the M20 engine doesn't like it. So I've flushed the system by doing the following: 1. Drained coolant 2. Put in a coolant flush & toped ...

That confirms that the ignition switch is at least working in position 2, and that the ignition signal is reaching the ECU, and at least turning part of it on. It also confirms that no conventionally installed immobiliser is causing the problem. Any missing voltage at the coil, would only affect th...

Not wanting to hijack the thread but what pressure rating should the cap be? I've got the one with 14 on it so will look at changing it as I've also got the heater matrix bypassed just now as it leaks. In the E30 WIKI it says "For that reason, BMW introduced a new pressure cap, rated at 1.4 bar. If ...

Have to say thanks for all the help over the past while with suggestions of what it could be and what to check.

Well I gave up trying to find a good used OEM CPS so ordered one from the dealer. Took them 2 weeks to get it in due to Brexit (I'm in Ireland) and €167 later I picked it up from the dealer yesterday afternoon. Fitted it this morning. 1st turn of the key and she lives. It was the CPS all along. So I...

Still trying to track down a good used OE CPS. In the mean time I've been doing some more reading. On 'e30owners.com' in relation to the CPS it mentions the following in one thread: "turn it over on starter and see if rev gauge lifts, handiest way of diagnosing rather than part swapping etc". When I...

Thanks again Brianmoooore. I'll try and tracked down a good used OE CPS. Failing that I'll get a new one from the dealer. Once I fit it I'll report back with an update. I was looking through some of the old documents for the car. There is an invoice for a new 5 Button G5 Clifford Alarm remote (would...

Car was running ok before CPS failed. It had failed to start a couple of times previous to failure of CPS but when running it was fine. Checked the original CPS again this morning. It is reading O/C between all pins. I measured the distance between the tip of the CPS fitted to the car and the toothe...

The car doesn't have a Cat fitted (at least it doesn't any more) . I have tried a 2nd coil but that didn't work. I was reading back down the posts in case I missed anything. I spotted that Brian wrote "A duff CPS call still produce enough 'noise', under certain failure conditions, to provide enough ...

I didn't think it would be relay related as there is power to the fuel pump (fuel pump relay ok) when trying to start the car (tested with test lamp) and the ICV buzzes (power from main relay) when key turned to position 2. Not to worry, I've checked the following: There are 3 relays under the black...

Blanca & HenryM3: I've tried a 2nd coil and made no difference. Blanca: On "Disconnect negative side of coil and with ignition on and using a bit of wire, flask negative to earth a few times quickly, should spark, I think.(depends on model)" this is what I did at point 11 that I wrote. Doing this I ...

Well after being in the garage from 07:30 to 12:00 I've (re)checked the following: 1. New CPS fitted = No start 2. Resistance at ECU plug for CPS reads the same as the CPS 3. Tried 2nd ECU = No start 4. Test bulb on Coil: - Key in position 2 = Bulb lights - Try to start car = Bulb stays on 5. Key in...

Thanks again Brian. I've checked out the blue sensor to ECU and it is actually OK. On the connector under the inlet manifold. Approx. 18 months ago I cut it out and soldered the wires together together. It's ran fine for approx. the 18 months. Couple of times it wouldn't start or cut out. The last t...

Thanks Brian.

Checked what you suggested. Lamp connected to + terminal of coil and to earth. Key in position 2 = lamp on. Try to start car = lamp still on.

Latest update: New CPS arrived from motor factor. Double checked OEM number from RealOEM and on Meat & Doria website to make sure I had the correct part = yes. New CPS fitted and still doing the exact same thing. Turns over, won't start, no spark with original CPU fitted. Will try again in the morni...

I've done a bit more investigation. The new CPS is from Meat & Doria. I've looked up the OEM part number on RealOEM and it comes back with 12141720856. When I look on the Meat & Doria web site for OEM part number 12141720856 it shows a different looking sensor (all metal like the original Vs plastic...

Well. I've verified the resistance of the new CPS changes when it is placed near metal and it does. I re-fitted the new CPS to the car and measured the resistance of it while turning the car over to make sure it is detecting the toothed wheel (in case the new CPS wasn't lining up correctly). While t...
