In December I had an unfortunate accident that wrote-off my SLK. I've purchased the car for its scrap value from the Insurance Company. I feel that I can repair it, but that can wait. So in the mean-time, I've bought another SLK to use.... this one : 2000 (W) MERCEDES SLK 320 KOMPRESSOR 3.2 PETROL AUTO HPI CLEAR SPARES OR REPAIRS | eBay It's got superb bodywork and cost £500. (It's a 230, NOT a 320, by the way) It was there because the cat had been stolen (and other reasons, that I'm now discovering!) . I've replaced that and then found a front wheel bearing had completely disintegrated. Replaced that, too. I think that the expression "all that glitters is not gold" applies here! It is looking like "a right can of worms"!
There are two lights permanently on .... The ABS and ESP lights. This is the list of error codes that are revealed :-

B1416 Coolant circulation pump
C1000 ESP control module
C1025 - 2 ABS stored
C1025 - 8 ABS stored
C1207 Implausible signal A7/7bl
C1101 - 2 Right front speed sensor
C1101 - 4 Right front speed sensor
C1140 - 16 Steering angle sensor
C1140 - 128 Steering angle sensor
C1141 - 16 Pressure sensor ESP
C1202 Release switch
118 Right rear signal
119 Left rear signal
120 Right front signal
121 Left front signal
134 Stored errors

Wow! That's some list! So what's it all about? Is it a control module that's faulty? I still have my damaged SLK, so I can take any component from it to try on this car. What would I be looking for?
The roof doesn't work, too ......
May I have your help, please?

David

Good you obtained another SLK. Please update your profile with those particulars.

That "cat" stealing seems to be quite prevalent these days (for the rare metals).

Hi David,

firstly, not all of the errors may be true.
Some items throw a list up.

What did you scan with?
I suspect that's the reason for a massive list.

As it can't be taken to a specialist to read I'll ask one of the top members, with much experience on this to drop by.

Given the massive number of related errors, I'd guess that it's the ESP module. Right? Many of the things that feed into it also have their own error codes also. Wouldn't a check-engine light fail your annual MOT? When was the last time the car passed an MOT? If it was within the last year, I suspect that all your codes have a single source, and to me it makes the most sense that that would be the ESP module or some other top-level component. Otherwise it seems unlikely that every wheel sensor, steering angle sensor, etc, would go out all at once. That is if the car isn't for some reason a car that was in a flood. If that's the case, then all bets are off.

Best of luck. Let us know what you figure out.

Hi David, couple of observations ..

(1) The roof won't work whilst those two lights are lit up so you can disregard that for now ..

(2) Your old car (sorry to read about that :() was a pre-facelift so there may well be compatibility issues in the parts interchangeability department ..

Which scanner you using to get these codes?

Thanks for all your help! The analyser was a "Snap-on", I think. The garage fitting the cat did it. I did consider that the drum/disc from my pre-facelift might not be compatible but all did look well. (Plugs/connectors, etc} How do I check that out? Where is the ESP module located? It would be easy to try a swap with my damaged car ..... I think that I'd know if the SLK had been in a flood! Heaven forbid! Finally, I'm surprised that "The roof won't work whilst those two lights are lit up". ? They would have no bearing on safety issues with the roof down? I'm still happy to be reading that, though. I was going to change over the pumps! I'll leave that for now. Oh, the car last passed an M.O.T. on 25th of March 2019, so it'll be needing one, soon. It has a truely massive amount of service history ..... One owner from new until 2018 who really cherished it .... huge Mercedes bills. Then the next owner who seems to have quickly passed it on to his Daughter. I don't think that it's been used much over the last couple of Years. I'm intrigued and I'm thinking of writing to thesed people to learn more! I think that it's been professionally sprayed. I've already got a load of stuff to fit to it ..... different SLK 320 bumper, silver finish grill, "Depo" headlights, "Designo" interior. I don't think I'm going to install liquid propane injection .... but I might! I only do 2-3,000 mls a year and the fuel cost saving is about £250-£300. It's just the pleasure I get from these projects!

David.

It doesn't look like a bad motor to be fair, nice mileage/bodywork etc. just needs rescuing :cool:

Lol .. I know that, you know that .. it's the vehicles inbuilt safety protocol that kicks in and prevents you from opening the roof when the car is travelling in excess of 7mph. Typically (but not limited to), a wheel speed sensor or wire goes kaput, giving a reading of 32000 RPMs when stationary and puts both of those lights on, giving an implausible value which in turn confuses the car :unsure: = no roof for you today sir.


You may well find that getting to the bottom of the BAS/ESP lights-on issue will cure the roof at the same time (y)
It may well just be a wheel speed sensor that's setting other things off further down the line and that Front Right is the prime suspect atm but you really need a Merc specific scanner on the old girl, clear the codes and see what comes back.


I'm not entirely sure that you'd be able to swap over any of the ABS/ESP stuff from the pre-fl, I could be wrong but I thought that they were 'similar but different systems'.. would need to fire up WIS/EPC to compare ..

Thanks, so where do I go to get my hands on that scanner? Are there any club members who have that? I would like to sort this out and move forward. There also seems to be a low level of PAS, too ....

Gotta be someone up your way David, apart from Inchape Mercedes at Llandudno .. maybe Myk @Avel Du knows ..



Of course, there is always this to try: Page 171 owners manual ..


Synchronising ESP

If the power supply was interrupted (battery disconnected or empty), the BAS/ESP malfunction indicator lamp may be illuminated with the engine running.

Turn steering wheel completely to the left and then to the right. The BAS/ESP malfunction indicator lamp should go out.

Hi David .................

First off clear that lot of codes out. Do the steering angle sensor reset (lock to lock with engine running).

Re read it, it is my bet that you have a Wheel Speed Sensor Fault, and a lot of the other stuff is some inept has been pulling plugs off things, the SAS Code is usually after a flat battery / disconnect ...............

@M4rCu5 has covered it, Roof needs to see Speed Sensor Readings or it won't open.

The HVAC Circulation pump is common, it is located under the Right Front Headlamp, I have that code on mine, and I have a new Pump, I will be doing it when the Engine comes out shortly as the Cooling System will be drained at that time ;)

SDSscan.

I use MDMotorcare for most of my work.
He doesn't like recoding, but should be fine with a proper scan.

Then there is MBMotorcare Warrington, An MBindy in Heswall, And Bucklow Hill Manchester.
Contacts in here


I was looking at SDS but never got around to it.

The roof was never going to work BECAUSE the luggage over-blind was retracted! STUPID ME! However the boot lid doesn't stay up because the two hydraulic dampers/assisters are U/S. I have disconnected the battery a few times. Do I go full lock both-ways with the engine running? I noticed a large bulge in the under-bonnet sound deadening material. It consisted of dried oak leaves, moss and loads of half eaten acorns. Have you guessed? Yes , a squirrels nest! Today, I've been changing the AMG front bumper for an SLK 320 upgrade type. I'm pleasantly surprised by the low level of corrosion everywhere! This car MUST have been garaged and cherished. Typical annual mileage was just 2500 - 3000 mls.I had thought that it had been professionally re-painted, but maybe that's wrong? I've mentioned that the steering seems a bit heavy .... what's the cause of that? "Depo" headlights and silver grill next.
I'm also a member of the A2OC club (Audi A2). There are certain members who offer their help and services to other members. So I'm wondering if there might be any SLK World members who, in a similar way, might be able to offer their help to myself? It goes without saying that I'd be very grateful and generous for that help .... I could travel easily or offer warm hospitality if a visit was made to my home, here in beautiful North Wales! The car's fully taxed and Insured, so it would be good to be enjoying it with better weather, of course!

Hi David,

This is not an advert, but since you asked ...........

I'd be happy if you want to spend a B&B trip in Dornie area, NW Scotland, I'll have the whole Car checked out properly in a couple of hours, then you can make your mind up if you want to bring it back in 1 to 3 days, (parts lead time), and I could do the repairs for you ;)

I think you could even do a ferry to Ireland and then from there to Oban which a couple hrs drive away from us.

Hi,

Start Engine, then lock to lock twice, the lights should actually go out before you complete the second cycle, always does for me on all MB's unless there is an actual fault ;)

Then as @M4rCu5 says, it's good practice to switch engine off and restart it ;) Lights should go straight out then ;)

Hot Tub is for me and Mel these days, the partying ;) ;) ;) was all done 16 + years ago when I was single ?

HTH,

Don't forget, first read them, make a note of all note or print them, then clear, short test drive and re read ;)

I'm tempted to take up your kind offer of help. It's ONLY 430 mls and 8 1/2 hrs away! It's a really beautiful area, that's for sure! It's a pity you couldn't visit me here .... free accommodation, super views, great food, good facilities and cash in your hand! Stay a few days! I'm a bit concerned that my SLK could fail on the trip to you .... it's the great unknown, at the moment. I still wonder just why it ended up at that reclaim outfit in Cheltenham .... somebody decided to just quit on it ..... and a car looking as fabulous as that!
