WANTED 1991 ASR module

[Randy Crooks]

I'm trying to find an ASR unit # 010 545 99 32 - Bosch # 0 265 106 034 for 1991 Japanese import. I've tried some of the part numbers recommended here as replacements but the aluminum mounting/alignment tabs are a different pattern and also the shape of the mounting tabs on my unit are wedge shape rather than rectangle like on the other units. If anyone knows of a suitable replacement or has the proper part for this car I'd be interested.

Can you post photos of the difference? All ASR modules should be physically interchangeable. I've never seen any that were not. The aluminum tabs should be the same as well. Note there may be 4 aluminum tabs and also 4 plastic wedge-shaped tabs.

EPC says the current number for a 1991 Japan-spec ASR module is 013-545-36-32, which was also used on early Euro-spec 400E/500E with ASR.

Photos attached of both, from Google search... looks like the 010- module was slightly modified in that pic.

I have one like you've posted but it's not close to my original, the pattern of the aluminum mating surface (The alignment grooves) is staggered in a different shape than the original, and if you look at it from a side view some of the tabs aren't 90 degrees to the case they are wedge shaped. I'll attach a picture of one I found on line and you can see the wedge. Mine is still in the car but I can remove it and get pictures. Also on mine it says 8 zyl/ 12 zyl.

Despite the different shape, does the module fit when you try to install it? Also are you sure the aluminum tabs are not bent? The tabs are just locating devices to prevent the wrong module from being plugged into the wrong slot; and to align the sockets on the colored plastic connectors at the base of the CAN box.

No it won't snap into place, it kind of teeters from side to side as if it's caught up in the middle and is about 1/2" higher than the other modules when it hits bottom. It seems to be the shape of those notches (Male and female) are not in the same location as the original module, the taller aluminum and plastic alignment pins are all square and perpendicular to the case mating surface and none of the electrical pins are bent or out of place. I'm going to pinpoint the differences in the two units later tonight and will post some pictures then.

I've found the difference in the aluminum housings, The tabs and grooves on the removable covers are identical but the location of the tabs and grooves on the main bodies are different. There are the same number of contact pins in both units and they are in the same location so I thought of just changing the guts but something tells me that's a bad idea, there must be a reason why they went through all that trouble to change those castings. The previous owner had removed the ASR bulb and I'm just trying to solve that problem, I keep getting a Left Front Wheel Speed Sensor code, I've replaced that sensor and cleaned the others but the light comes on once the car moves about 10 feet so I'm looking for a spare module and hoping there's something wrong inside my old one.

That is WEIRD. Just to confirm, you have 010-545-99-32 (original) and 013-545-36-32 (replacement)?

Are both ABS and ASR working correctly, despite the warning light?

 

[Randy Crooks]

I see the problem now , I can't believe I didn't double check the number of the ebay unit I recently bought, i ordered a 013-545-36-32 and they sent 013-545-39-32 I think that one fits a 500sl. I appreciate you straightening this out for me but I'm sorry to have wasted your time like that. To answer your question, yes the abs seems to be working but the traction control seems to be erratic, it will sometimes just spin the right rear wheel and other times you can feel the rear brakes doing their thing.

Hmmm. 013-545-39-32 is for a USA-spec 124.036 (and, 124.034 with optinal ASR).

013-545-36-22 is what the EPC lists for Europe/Japan.

If the housings are keyed differently to prevent interchange, that is news to me! I didn't know that!

I wrote the part number on the ebay part that's in the bottom right picture and they're definitely different. I think I've got the only 500E in Nova Scotia and for sure the only Japanese one, so there's little chance this part will get used. I'll put it on the shelf and if you need it it's yours no charge, I owe you that for solving my problem so quickly and also helping me out several times back in 2012 when i bought my car.
