Hi guys

This is going to be a long post Bear with me and I hope some of u guys will be able to assist

I'm based in Malaysia. Purchased the car last year. Its a 95' SL500. Problem is with ASR since day one of purchase. What I was hoping to be my dream car is now a frustrating machine that I've spent a fortune on (including other non LHM related repairs)
​​
ASR light comes ON. Car goes to limp mode. What I have done so far

1) after meddling with the ETA I sliced the insulation opened and true enough it was crumbling. At that point The rpm was going yoyo as Victor's video. Sent my ETA to a local guy claiming he is able to repair. He screwed it up. Ended up buying a new rebuilt throttle Actuator from Beckmann Technologies. Car was okay for couple of weeks then bam! Same problem again. ASR & LHM

​​​2) Replaced brake switch

3) Inspected the wiring harness.. Looks really good Sliced open the harness running thru the injectors and the insulation looks brand new Probably replaced by the previous owner The bottom harness however looks pretty bad I saw this when replacing alternator

4) STAR diagnostic shows error :
ASR 030 : CAN No reception from EFP N4/1 or no reception from EFP EFP 048 : Set value potentiometer. Potentiometer monitoring M16/1r1 LH1 025 : camshaft timing Actuator 2 Y49/1 AB 019 : Airbag malfunction indicator lamp A1e15

5) Camshaft Actuator replaced. Error still there. Another error came up. Knock sensor fault

6) I figured if I shorted pin 1 & pin 6 it will solve the problem Wrong It limped too. My hypothesis is now that it limps not because of the ASR components (asr pump & module)

7) I'm ruling out ASR module because most post I read the problem was solved without replacing the module even tho the error did show up.

Could it be the ETA I purchased is faulty? How do I diagnose that? Next week I will be replacing the gear neutral switch. Read that it may be the cause too. Also, the throttle clip to the spring like mechanism (behind the engine) that goes to the ETA is broken. It is really loose. I have ordered and It will take 3 weeks to arrive Malaysia Just incase, I will replace that too.

Anyone reading this post If you have any idea please assist. I'm in dire need of help. Thanks in advance

You have a code showing no communication between the throttle and ASR controllers. I believe that is the cause of your Limp Mode condition.

Use the appropriate R129 diagnostic manual to troubleshoot the faults reported by Star Diagnosis. A main menu with links to the various manuals is here: http://manual.startekinfo.com/manual/JSP/model129.jsp.

Replace or rebuilt the bottom harness too, also check if the MAF harness is good or not. An easy way to check it is to unplug it and see if there are substantial changes.

Looking to replace the bottom harness Hunting for the part correct number now. On another note last week I replaced the neutral safety switch. LHM still there. Intermittent.

Also my throttle linkage is broken. It was modified with some diy brackets by the previous owner. Just found a used unit. Will have it my hand sometime next week. The throttle cable plastic adjuster is broken too. Held together by cable tie (also by previous owner) Hunting for new throttle cable now. M119 is a rare sight in Malaysia. The govt annual road tax is based on the engine capacity. Found one online a company based in Latvia who has stock. Will order it this evening.

Thanks Bob. The STAR diagnostic using PC is as detailed as the sequence counting tool or is the same? Problem with local indy is that they take the easy way out Replace what's shown in the star. I'm thinking of buying a counter for my self and learn up the method

Great link. Thank you!

UPDATE

ASR ECU module replaced. Still same error. Intermittent.

I manage to get a used throttle link. But I can't seem to find brand new throttle cable. Part number is 1293002530. If anyone can share a link to a website kindly share. Thanks

Have been driving for couple of weeks without LHM. I sprayed WD40 at all joints of the throttle linkage. That's it. I hope this thread will be helpful for new owners like myself who may face similar problems. The end (hopefully).

Hi imagicaz, I saw that you sprayed WD40 on the joints of your throttle linkage. Can you post photos of an example of the linkage you sprayed?
