Bas/esp

Anything over 12 volts is OK for a good battery,,starting blips as they are caused is when the voltage sinks to low when trying to start,and a test here would not go amiss

Could I have your Email address please

 

[television]

I have sent you 2 documents

 

[Myros]

both received

Thanks Malcolm. You are a gent.

 

[television]

See what you make of them,its not an easy subject

 

[Myros]

your'e telling me Malcolm

although i did manage to install a hands-free phone kit the other day. Mainly plug and play though.
I'll print them off and have a proper digest tonight.
I baulked at disconnecting anything major looking in the electrics tray in the engine bay in case i knocked something else off line.
I must be getting too grumpy for all these electronics.

 

[Myros]

anyway, the latest update

as I said on Sunday Malcolm ( a pleasure to meet you btw) I spent saturday morning up to my elbows in steering wheel and gizmos. Got the clearance between the clock-spring and the steering sensor to be 4mm all around (it was 3mm before i attacked it). It should be between 3mm and 5.5mm according to the star paper you sent me.

The diagnostic says it's not the problem now, but it's the ESP Control unit. Just priced one at MB and they had to revive me with soft music and dim lights. Ouch. Likewise the hydraulic control unit. Even more hard-earned for one of those.

I also ran it by an indie who had a quick sniff at it and put it on their star machine. Guess what? Steering angle sensor. Having read the paper, which says the SAS is really highly unlikely ot go wrong, and should only be replaced as alast result, I'm reluctant to shell out for another, when i probably didn't need the first one.

Those nice chaps at MB Tech think it might be the diaphragm position sensor. At £52 quid, it's an affordable swap, but i don't thnk that's the culprit either.

This fault didn't arise when driving, or as a result of hitting a pothole or anything. It brewed up in a hot sunny car patk. I parked the car in the morning, it was okay, came out late afternoon, and the fault appeared.

That sounds to me like something electronic had broken down in the interim. I could see the heat causing a clearance problem with the clock-spring, but it's now adjusted correctly ( it was on the limit before). I think therefore that it's something in the engine bay, that hothouse of hotness. That makes me think ESP control, or the diaphragm sensor.

I'm going to clean all the contacts in the EPS/hydraulic thingy, disconnect the battery for 30 minutes, reset everything, do the lock-to lock trick, and if none of that works, look out mercman an Dronsfields , here i come.

 

[Myros]

so here goes the great MB swapathon

bought a used ESP BAS control unit yesterday. Fitted it this morning, and guess what, all the warnings still come up. Gave it three starts and wibbled the wheel lock to lock three times just for good luck, no change.
Can't get the codes cleared this weekend, bank holiday apparently.
So all that's left from the battery of fault codes is the hydraulic control unit. Haven't sourced one yet, and might not need one yet, as the fault code clearing might do the trick yet ( not holding my breath though).

Any thoughts anyone

Is the ABS lamp on

 

[Myros]

oh yes

bas/esp lamp, and abs lamp, and the three dashboard warnings that go with it in the display.
New brake light switch first thing I did, then the steering angle sensor ( correctly adjusted, thanks malcolm) and now the esp/bas control unit, all changed for new or guaranteed to be good used.
Flummoxed would be a good way to describe my state of mind.

 

[television]

The last guy with this fault I told him to wriggle the connector on the ABS pump as dry joint can happen where it plugs in,, They can be soldered up OK have the engine running and someone watching the dasg when you do it,,sometimes a restart is needed

 

[Myros]

Thanks Malcolm

I'll have a go after lunch, when I can have the mem's undivided attention. The way this fault occurred made me think dry joint straight away ( just in a hot sunny car park all day), but which one?????
The abs pump is the thingy with all the pipes and the multi pin connector just halfway along the the left inner wing?

 

[Myros]

had a go of the wiggle thing

after cleaning up the pins and sockets with contact cleaner and an old toothbrush. I then lightly coated the pins with copperthread ( you'd hardly notice, but it should keep them clean) and wiggled a bit. No change.
Plan c next.

 

[television]

If it does turn out to be the ABS pump then the electronic box can be remover without interfering with the hydraulics

 

[Myros]

I have actually removed the black electronic box

had a look at it, not known what the h*ll all those little stubby pipes were for that fitted into it, and put it back again. I've also put my "old" esp control unit back on, and tried it all again, with no change.
Life is a voyage of discovery, so far, to find the bottom of my wallet. Still, it's coming in a lot cheaper than if MB were doing this for me, as I don't think they'd have any more clue as to what is wrong than i/we do.

diferent problem to me, but i really know how you feel!

 

[Myros]

solved, permanently I hope

by replacing the burned-out 7.5 amp car alarm fuse. Thanks to Mikimogo. see his excellent thread on the topic.

 

[television]

The hard thing was that there are 3 versions of this,,yes now I have found the correct one fuse 11 it controls the level control on ADS cars,, ESP and steering angle sensor.

It also does the ATA inclination sensor , left motion sensor,and right, also the signal horn.

We will know the next time

 

[Myros]

that's the one Malcolm

I'm keeping it as a souvenir. if you hadn't sent me that paper from star, I'd be on my third SAS by now.
Deep down, I knew it had to be something simple by the way it failed.

 

[television]

At least looking on the right side you have other things working that you did not know had stopped,,The confusion of the 210 with 3 different fuse box layouts make it very hard sometimes if the car is not in front of you,,first layout goes till 1977 then till 99, and then after 99
