The 1990 525i, doesn't have a stomp test feature. That didn't become available until the 1992 models. You can find the thread here, I read it from one of the sticky's "mechanical things you should know...". Its the first post under "stomp test procedure"

Again, BMW specialists that are on here, if I'm wrong post, that way I know, he knows, and its confirmed. Hope I help and thanks guys.
That information on the stomp test page is wrong. They got that from the bentley manual and the bentley is wrong in that regard.

All cars with Bosch Motronic version 1.3 and above have stomp test capabilities, that goes for ALL e34's.

Heck, even my 8/88 M20 has stomp test capabilities.

What you should be buying would be the crankshaft position sensor.

Great that you've got the pump. ;-) You'll need the fuel pump's fuel tank entry orifice's O ring as well. If you forgot that, please purchase it before installation.

Please don't forget an assorted set of car fuses kept as handy spares, and new relays for your fuel pump, dme, abs and o2 sensors. Especially a new relay for the fuel pump (but you might as well get them for everything else along the way). The old relays can be kept as spares.

You're nearly at the point where you'll be sitting back, reading posts, and wondering why people have no start problems with their E34s.

Dont have time to go through the last few replies and commen on them, just have to ask a quick question. Going to work this morning i got in my car and tried to switch to reverse and nothing happened. It seems i cant switch to any gears, it sort of just easily flows through all options. Whats my problem? Any help would be greatly appreciated as my car is out of commision at the moment.

Well disconnect the ecu for 5 minutes to erase all the error codes, then reconnect it, then restart the engine and see if everything is back together.

Ill give that a shot when i get back from work. Some of the possible problems ive been reading include my transmission being shot. However i dont think thats the case as it shifted just fine when drivig. It just feels like its not catching when trying to put the car in reverse, drive , etc. Thanks for the info Robert

Just so you'll know, my previous E34 lost reverse at 256K miles. It wasn't worth it to me at the time to have the transmission rebuilt. One option if yours is going out is to do a 5 speed swap.

Good luck.

I have an idea. Discard what I said earlier for now. Start the engine and see if your transmission works normally. If it doesn't, put it into neutral, engage the parking brake, and then let the engine warm up for 15 minutes (or at least let the engine reach operating temperature and then give it an additional 5 minutes).

Then try to engage gears. If it works, then your problem is a lack of transmission fluid. When you warm up the engine, you will also warm up the transmission fluid. Hot transmission fluid expands and occupies a higher volume in your tranny, which will allow the tranny to engage. The sensors will only allow the gears to engage properly if they detect sufficient fluid...this prevents damage due to a lack of fluid. You should then have the car checked for any leaks, and change the gasket, filter and transmission oil as necessary. Further proof that you should have had the car at a workshop before buying it, if this is indeed the case.

If you have a dipstick (should have thought of this earlier duh ! ) Please check the level. If it is low, then top up synthetic oil through the dipstick tube using a small funnel until its at the right level, then try again.

If this whole thing doesn't work, then read the codes via the stomp test, delete the codes as mentioned in my earlier post, and start the engine and try the transmission again.

Let us know how it goes.

I need some more time to fully test your idea, each time i do my kid starts crying or something happens. So right now i havent gotten it to normal operating temperature. However, i cant really put it in neutral. I can adjust the shifter so it reads "N" on my dash but it doesnt actually switch in to neutral. I checked my fluid and it is indeed low, so i am going to put some more in there. However, i am a bit confused as how to do that. Ive read through the bentley manual and understand i need to find the fill plug on the pan, remove it and fill from there. But locating that seems to be harder then i though. I bought a jack and jacked it up to look under there, but i only see the oil drip pan. From what i read, there is a drain plug on this pan just as there is a drain plug on the oil pan. But i only see one pan with a drain plug underneath. I know im probably missing something obvious, so feel free to slam some common knowledge in my face. To make matters worse, the birds seemed to be having a ****ting contest on my car and i cant even move it to avoid their droppings. Poor car.

Took a rather lame video, mainly to let yall listen to my engine. After my tune up my engine sounded great, not like it does now. Since i know next to nothing right now, im not sure what these sounds mean. Any ideas?

Fixable problems. Probably some pulleys, tensioners, and loose belts too. Fixable problems. If they are related to the pulleys etc they should have been done during your radiator job. The mechanic who did it should have checked all of this (takes 3 minutes) along the way, its being professional.

Don't worry about the terrible sounding engine. All the issues are fixable. Do the fuel filters and run diesel through your fuel tank to clean the injectors. Clean out the ICV (idle control valve). Check and clean or replace all the spark plugs. Clean the throttle body. I'm sure your engine will run really great. It just sounds clogged.

You mentioned the throttle position sensor earlier. In my experience, that usually does not go bust, but it helps to clean it and its connector with contact cleaner before you reconnect them. Ideally, after cleaning, coat both the connector and TPS with dielectric grease before you reconnect them back.

Awesome, thats some good news. Yea when i get time i want to clean and check my sensors. Along with cleaning my throttle body, and intake. I just cleaned my ICV today, I just need to get my transmission working so i can actually drive it. Thanks a ton for all the information, you are very knowledgeable and it really is helping me out.

Sorry I never got back about the door lower trams. No clips no glue they are retained by their own shape. Flush out dirt (salt?) dry and refit after you clean up the bottoms of the doors. About a once in 2yr job.

How did you check the fluid ? Was it through the dipstick ? That must be the case, since you don't know how to locate and remove the fill plug and so couldn't have checked any other way.

This means that your transmission has a dipstick. This means that you can top up tranny fluid through the dipstick, using a small funnel which can be purchased at hardware stores. So you don't need to go through the drain plug etc.

Don't know why I missed this point earlier. Stressed out I guess.

I wouldn't be surprised if your radiator guy did not do a good job with your water pump, thermostat and fan clutch. Many of those squeaky noises in your video are belt/pulley related. I just changed my water pump yesterday and was told by my new mechanic that the water pump's pulley did not look right. He asked me if I had had an accident before ! That's the only way that dent got there. I hadn't, and surmise now that the mechanic who did my water pumps last year and years past much have negligently handled the pulley, and/or must not have bothered to take the 30 seconds that it takes a seasoned person to quickly inspect it before reinstalling it.

So, if I were you, I would go back to whoever did this for you and get him to fix it. Insist the noises showed up shortly after you got your car back. Usually they do start out with softer squeals before getting loud enough for you to hear with the hood closed. You might not have heard the initial issues.

Is your engine a single overhead cam or a twin cam ? If its a single cam, you have something called valve lifters (google and youtube), and they need to be adjusted to maintain correct clearances, ideal performance, and avoid that 'tick tick' sound I seem to hear in your car. The valve cover gasket is also changed during this operation. Depending on who is doing it, this could be take nearly 2 - 3 hours to do correctly.

I think you should get your car to Joachim and have him look at it quickly. Let him take 15 minutes with it and at least tell you what's wrong. Especially tell him to inspect everything that the other mechanics did recently. You can come back another day to do the actual repairs, if he is not free. It might be a very good idea to just get a heads up in case something major is about to happen.

You could also check to see if the shifter linkage has disconnected from the armature on the side of the transmission.

Crawl under with a light and look at the drivers side of the trans.

So update time. My kid has been in the hospital for the past week, which is why i haven't posted on here or worked on my car at all. However, i finally got some time today to work on it. Here is (which i doubt). I have yet to try your suggestion paper plane, i will do that before i go to a junkyard though just in case it is that simple of a fix. When i was taking apart the shift lever and such, i noticed a small piece just hanging out freely, any idea where it goes? I didn't see anything like it on the gently manual.

Also, this connector (the white one) wasn't even hooked up, was just hanging out chill in. Seems wrong to me, what is it?

I think you've found your problem. I also think you need to show these parts and pictures to Joachim.

Ok, I think i may have found your problem. I have a spare transmission range switch over here, it is yellow in colour, with a curve on the top kinda like an aerofoil (you can imagine the stick moving over this as you engage), and it has the exact same number of live metal prongs (7) and in the exact same shape that is found in the black plug over in your picture. Obviously, the two are supposed to be plugged into each other.

If your transmission range switch is busted, you won't be able to engage your transmission. Sound like the problem that you have. If that got disconnected, you wouldn't be able to engage your gears at all. That's it.

You may need to pull up the cover around the transmission that we see in the picture, to access your transmission range switch.

Basically, if you see something that looks like its unplugged, look around carefully for its corresponding socket. It probably belongs there unless you're sure it shouldn't or has been disconnected deliberately for some reason.

Well the black connector was plugged in, i just unplugged it from the switch when taking everything apart. The white connector was the one that was just hanging freely. But yea i do think it could be a busted neutral switch regardless. As for my kid, shes doing a lot better now. Not sure if anyone has heard on the news about the chemical plant that produced medicine having a contamination in their products which led to an outbreak of meningitis. Well thats what my daughter has, spinal meningitis, which luckily was caught very early so shell be A ok.

PS- who is this joachim? A member here?

Sorry to hear that your daughter fell victim to this fiasco. Glad she's doing well and my best wishes for a complete and quick recovery.

She's a champ she has cheated a fate worse than death ! Please congratulate her for her brilliance and buy her whatever she likes to designate this triumph.

And Jaochim is a mech from another thread lol I got mixed up.

What is a neutral switch ? Is that the transmission range switch ?

Yea same thing i assume, in the bentley manual it says neutral safety switch but from what you describe they sound like the same part. Thanks for the kind words steve and robert, i am very relieved to have learned about what meningitis was AFTER we were told she would be just fine as opposed to before. Damn chemical companies not handling their business.

Update:

Its been awhile, but i finally got my vehicle fixed a couple days ago. After diagnosing the problem, ordering the part from BMW, them ordering the wrong one and having to reorder the correct one i finally got it in and replaced it. Turns out my shifter cable had snapped. Since the last time ive posted ive done the following.

Replaced valve cover gaskets, exhaust manifold gasket, ignition coil, wires, shifter cable and i painted my heads for fun. Its driving a ton better now, so next will be little things to make it more personal to me.






Before (but after being heavily cleaned)


After and mostly installed:
