1998 CLK230
The vehicle is a 1998 Elegance in quartz blue with just under 90k on the clock, all documented and in fairly good order. Bought it on a whim about 7 weeks ago and all has been fine and dandy until last Thursday afternoon.

It was a glorious spring time day here in Sheffield when I decided to visit the local car wash (the sort where Eastern European types jet wash, hand shampoo and dry the car for you) this may or may not be significant. On leaving with a nice shiny car I noticed that the indicators were suddenly not working, nor the windscreen wipers and headlamp flash. In fact all functions on the one stalk, apart from the headlamp high beam, were, well non-functional. I limped home as best I could with no indicators and visited the local garage at the end of my street for some help. He suggested a local specialist auto-electrician who had all the gear for working on Mercs, BMW’s and the like.

I gave them a ring and was quite impressed when he said he would be right round and check on it. Within 20 minutes he was on my doorstep and soon plugged a laptop into the car, checked all the fuses (which I’d done already) and eventually came to the conclusion that the indicator stalk had suddenly failed and would need replacing. By this time it was late afternoon and he suggested that I drive round to his premises the following day and we could see about getting a replacement.

The following morning I took the car to him and after finding the exorbitant price the Main Stealer wanted for one, I rang Mercman in Cornwall who had a reasonably priced new one and could courier it but it wouldn’t be there until Monday. Not a problem at that time because I didn’t need a car over the weekend, so I waited for Monday.

The part arrived yesterday lunchtime, I took it down and left it and the car with the AE. On my way there I found that my indicators and windscreen wipers were again working but not the headlamp flash?? I mentioned this as I handed over the car and parts and was told that it can be the case that parts can apparently start to seemingly work, only to fail again. My nightmare, or at the very least a bad dream, started then. Mid-afternoon they call to say that the retaining bolt for the steering wheel would not shift under any circumstances. He suggested that it be left overnight, liberally coated with some easing fluid, to hopefully free off the following day. He was worried, and I have to agree with him, that excessive force might result in it snapping off and the ££’s turning to ££££’s.

So today, I received the call to say that after bathing in exotic oils overnight, the bolt still refused to shift and would have to be drilled out. ‘Ok, not a problem’ I said, ‘do what you’ve got to do’. I offered to pick up a replacement bolt from the main stealership (cost £4.08) and ferry it over to them so that they could finish off the job, which I did. So after everything was put back, I cheerfully pay for the labour and go to drive off to find apart from the fact that my pristine Orion Grey leather driver’s seat now has grease stains on it, that…………………..

Yes despite having a brand new stalk fitted it’s still not bloody working! They said that it must have triggered a fault with SAM, whoever he is, and that they will have to now remove that and investigate looking at doing some sort of re-soldering as contacts may have ‘overheated’??
I don’t know, maybe I’m worrying unduly, but I’m beginning to wonder, firstly , do the auto-electricians know what they are doing and secondly, did I know what I was doing buying a 13 year old CLK!

If anyone can offer any kind of advice regarding this electrical fault I would be grateful because I’m beginning to think that this could end up a significant hit to my wallet.

If nothing else, thank you for listening and allowing me to voice my worries.

best regards
 
Should have taken it to the main dealer. Would have been cheaper in the long run. LOL

Unfortunately you may be right but I didn't fancy the eight mile journey without indicators to the other side of Sheffield...... so might not have been cheaper after all, RTA, insurance claim, loss of NCB, Police prosecution etc etc!

The amazing thing is that I regularly see Mercs, Audis and Beemers being worked on at the premises so you would have thought they'd have it sussed??
 
i have the same problem in my clk. i stopped off to get petrol and when i restarted the car i had no low beams, fogs, indicators. wipers or jet washers. so i taught it was the stalk also so i changed that mydelf and also the light switch while i was at it.
when i reconnected the batt and tested to see if it worked. full sure it would work. i was wrong but i had got back fogs and low beams. i cant understand why i got back some but not all functions.
what was working when ur stalk broke?
i had only hi beams & parking lights!
i was thinking did the car go into some kind of limp mode? some kind of protection?
i cant get mine looked at with the merc specialist for 2weeks due to the way i work. thankfully i have another car to drive.
so if you get ur sorted can you let me know what had to be done. im hopeing it is only a limp mode.

Well the latest episode to this saga is that they have decided that moisture has got into the front SAM via the fuse box area on the driver's side. A new one from Merc is £200 but I have got a complete unit (Front SAM & the upper fuse box thingy) coming from Dronfields by courier, arriving tomorrow at a cost of £35 plus £8.50 carriage. As soon as it's done, fingers crossed it will all be ok, then I'll post a result.

A very helpful member on another MB forum, who certainly seems to know his stuff, mentioned that the original covers for the fuse boxes and SAM unit were very prone to the ingress of water and dampness and this is a common fault. Apparently a modified cover is available, at reasonable cost, that doesn't let moisture in. He is going to send me the part numbers so I'll post those too when I get them.

I just wish I'd posted the problem before I went buying a new column stalk and paying to have that fitted. The SAM unit is an easy fix it would appear and would have saved a mint in labour. There again the AE in my opinion should have had a bit more of an idea but that's another argument :mad:

To answer your question 'what was working before it happened'. Answer - everything, the car has been running absolutely fine until this happened.

I'll hopefully have news of the good variety tomorrow.
 
hopefully that will sort it out for u. as its a nightmare ive looked at the car alot of times trying to find fuses blown hopeing a missed a fuse box as their is a few in the car. so hopefully when u replace the part and it works mine will be the same.
thanks for that info hopefully it will work :)

Well as they say, all's well that ends well. New SAM and Fuse box attachment arrived this morning and fitted and all is now indeed well. Unfortunately it would appear that all the efforts, not to mention the cost, of replacing the column stalk were a total waste!

To the person who mentioned that I should've taken it to MB dealer, that may be so but financially I would have been worse off strangely enough. New SAM from MB is £200, plus it turns out I would have needed the top fuse box attachment (cost unknown), plus labour (got to be at least £100) I reckon £400 or in the region of.
I've spent 60 inc carriage on column stalk & 50 inc carriage for SAM & fuse attachment plus labour (£100) so I'm better off, if but a little greyer and balder! :(

The old fuse attachment had obviously been subjected to a lot of moisture ingress over its 13 years use. When taken to bits all the contacts were green and corroded quite badly. The SAM is a sealed unit so it's impossible to know what the damage was to that.

As I mentioned in a previous post on this thread, apparently there are available modified fuse box covers which should stop any moisture entering at all and when I have the part numbers I will post them up for members' information as well as buying a pair.

I hope that helps you Dax get your problem solved, let me know how you get on. :thumb:
 
For those interested the replacement waterproof covers are:

Part no. Designation Quantity
A 202 545 14 03 Module box cover, small (old no.: A 202 545 13 03)
A 208 545 00 03 05 Fuse box cover, large (old no.: A 208 545 00 03)
 
thats great to hear. glad it all worked out for you. i will get the parts for mine and ill let you know how i get on. fingures crossed it will work out :)
