W124 wiring loom part no. - dealer won't tell me. HELP??
Discussion
Hi all
Looks like my E320, purchased only 3 weeks ago, is starting to exhibit the dreaded engine bay wiring loom issues.
There is no label that I can see with a part no so I rang the local dealer with my chassis no.
They will tell the price but WILL NOT tell me the part no.
£1848!!!! plus fitting.
can anyone with access to EPC help please?

Shockingly high price!
If you're in the Mercedes club, and really really want the full loom, then you will be able to get a discount and advice on where to have it done cheaper.
When my C36 loom was on its way out, my mechanic chap took it to bits and spliced in new wire where needed and then insulated the lot with the latest super insulating stuff available.
I think it cost about £200, and my mechanic summed it up well when he said " Well, it's just wire isn't it."
Good luck!

Thanks, butI've seen that link before, but I can't make head nor tail of it. How on earth do you use it?
Apologies for being a numpty
Yes it's 1995 E320 saloon, with climate control (if that makes any difference), without cruise control. Also no ASR/ADS I don't think.
Only thing dealer will tell me is that it is NOT no. A124 440 2933 - but I've read that the dealers can get it wrong and say you need 124 440 5632 when you actually need 124 440 2933 and vice versa? I don't know.
Thanks for offering to help.

The go to place is http://www.sileck.co.uk/
Send him your old loom, he'll duplicate it and send it back, he'll also rewire your throttle body (it'll probably need it)
Removing/refitting is straight forward, and do the lower loom (only a few wires) yourself.
No connection except being a satisfied customer.
BTW
That price from MB is way too high, MB quoted £700ish + VAT for my SL320, twice the price of Sileck.

A 124 440 32 33 or A 124 440 52 33 I'm not sure which, I think the former. Expensive: http://www.mercedes-benz-parts.co.uk/index.php?opt...
The loom for my car (cruise, no ASR) was circa £850 from MB 18 months ago. I tried two dealers and both (on this and other bits) are happy to give part numbers.
As mentioned above, if I was doing it again I'd be tempted to get it rebuilt rather than a new loom - I have seen Sileck mentioned positively before elsewhere, and Tony Leach on the MB club is universally praised (and did my throttle body).
ETA - I've just checked my receipt - the part number is A124 440 34 33 - £762 plus VAT. I'm not sure the presence or otherwise of cruise makes a difference, as the only connections, from memory, near the throttle are to the resonator which sits on the inlet manifold. The part number on the old loom is a white label quite close to the ECU connector.

Jonathan - that's a great help, as always. Thank you.
Steve - got your pm and have replied, fantastic!
PositronicRay & Scotlandjim - thanks too.
My indy recommended me an autospark not too far away. Spoke to him and he's familiar with the issue and prepared to look at the car with a view to rebuilding the current one. So that's an option.
If I end up getting the whole thing sorted for significantly under £1k that'll be a result. Just 'effin annoying when you've only just bought the car, especially as I reckon paid over the odds to start with, but hey ho.

As interested fellow owner, what were/are the symptoms?
Nothing when the engine's cold, but when it warms up the tick-over gets a bit lumpy, then it can drop off a cylinder or 2. Obviously there are other faults that can cause the same symptoms, but I believe these are fairly typical of a failing wiring loom.And from this morning a new symptom. I touched the temp sensor plug last night (and noticed the insulation had gone) and from this morning the cooling fan runs continuously.
And then on the way to work, a new and sinister symptom. The lighting circuit came out in sympathy and spat the driver's side indicator unit out onto the road!!! Just as well I have a spare or 2, eh?

If your having running problems, spurious codes, warning lights and the harness is bad then replace it. It'll need doing anyway and you'll have eliminated it from your diagnosis. Shorting out can damage ECU's and TB's

This was one of the first jobs I did on my 280TE project, M104 engine. Whole loom was knackered-why on earth did they use heat-degradable plastic! Made a new loom myself-took a long time (wasn't in a rush) but is a really simple job of just replacing like-for-like wires and soldering them onto the connectors. Colour coded each circuit, replaced damaged connectors (some were really brittle and broke when unplugging) and rapped the whole thing in loom tape.
