Got my 80MM TB on and it is not taking adaptation from Star. They swapped the pins 1-4 and 5-6 and its still not working.



here are the part numbers of what was installed

AMG 80mm TB - 113 141 05 25

S/C inlet 80mm - 113 140 09 12

S/C inlet gasket - 113 141 07 80

80mm TB gasket - 137 141 07 80

80mm Y-Pipe with tubes - 113 090 03 29

I've heard of this. I'll check and see what ever happened. i know it worked out. I want to say the wires were goofed up.

prodigymb

yeahi think the wires are good and my stock throttle body wasnt bad either. the problem is in the ecu

got a spare?

There are several 80mm TB numbers out there. My 80mm worked swaping the same wires out but maybe your model did not need the wire switch? Did you double check the pin connection and also make sure correct pins were switched? Basic questions but would assume it is one of the three posibilities.

My 80mm tb numbers are A113-140-01-04

I have 25 part nu,7mber in my car. And it works.

When I installed it I connected the bypass and T/B back to front. The lead on the loom with the blue tape around it is for the T/B. The plain black is for the Bypas valve (which incidentally and just for your info is the same part number in an SLR - nice to have something in common) If you connect the leads incorrectly, once plugged into star diagnostics you get a capital F for major fault which can not be downgraded to 0 fault untill the error is rectified and tags up as an f (lower case) fault.

There is no change to make to the wiring of the T/B, My wires into the t/b and into the loom remain the same colours as the OE e(( loom.

My car, when I fitted the T/B in my arage started but would not open the throttle, i expected trouble beforehand and took it to main dealer where mymate works who sorted it out. I wil ask him what he had to do to make it run and post it asap.

Dont worry - all is not los and my car puled smoother and harder at high rpm after sorting

exotic nailed it on the head. Yours is an 03 and the wire flip is for the newer cars.

You not saying you have a bad ecu are you?

prodigymb

yeah it looks like i do have a bad ecu

The problem is in the potentiometer. It is wired differently in the SL to the E55. The TB you have is from an SL.

You need to change a couple of wires around.

I will be able to tell you which later today.

prodigymb

i did change the wires, but any additional input you have is welcome. thanks

Prodigymb - try this to get it working.

Put back any wires you have changed already. The wiring colours on the TB should look the same as the original for this to work.

Pop the bonnet (hood) on the left at the back is a fuse box, 2 slide clips undo it - pull the top off. The silver box on the left sitting front to back in relation to the car is the ECU, it has five plugs going into the top of it that you can see. We will call the plug at the front of the car 1 and count back towards the rear of the car.

On the first plug, you need to swap the blue and the black wires.

Then on the 3rd plug switch the yellow and white wires. There are a couple of pairs of yellow and white wires, i am quite sure it is the thinner ones on the grey board of the plug in holes 20 and 21.

You can easily change these wires using a tiny screwdriver to release them.

When you restart the engine, the system will not diagnose the problem as a major fault (it is doing this at the moment as the voltage outputs are all the wrong values, and outside the parameters set for the TB to the ECU - this will put the right value to the right place) On start up the fault will automatically downgrade to a minor fault and the car should work without any problems. The next time you get a chance to get it plugged into diagnostics, you can clear down the small "f" fault stored for the TB but it wont stop the car functioning correctly in the meantime.

Hope this gets you back on the road.

I will check the pin positions tomorrow if i get 5 mins, but you should have enough info already.

A note of caution to others reading this thread - this is only in my experience in installing a TB of the same part number as prodigymb in an 04 lefthand drive e55 and i cant say if it would work on other TB numbers.

jangy

Any good?

I remember the issue had to do with various years E55 and not just E55 to Sl55 differences. Keep in mind it is an '07Sl55 part.

prodigymb

still nothing. hopefully i will get it running this week

Bringing this back to the top.

I'd prefer to order the TB & associated parts & save myself about $700, but I've got 2 questions:

1. Is the wire swap required for '04 cars?

2. I see switch wires 1 & 4 and 5 & 6. Not having an 80mm TB in front of me, or my stock one removed, is it obvious which wires are which? I'd hate to end up swapping 6 & 3 and 1 & 2 if I get it backwards.

Any help is appreciated.

prodigymb

As far as I remember the wires are labeled... and yes you do need to swap wires.

Prodigymb,

what was the problem?
