SLK/R170: ASR/BAS Warning light
My '99 SLK has just developed its first fault. After it has been running for about a minute the orange ASR/BAS warning light comes on and stays on. The car drives perfectly normally other than the light being on.
Has anyone else seen this, and are there any horror stories about really expensive fixes being involved ?.
Any and all input is most welcome.

Many thanks for your suggestion. I haven't had the battery disconnected. I did however try turning the steering wheel lock to lock whilst the ignition was 'On' but the car not started. Sad to say it didn't make any difference.
Sometimes the light is on straight from cold, other times it comes on after the car has been running for a couple of minutes.
I guess I’m going to have to screw up my courage, take a deep breath and visit my local Merc dealer. I’ll just put a smile on my face and say "my time to empty your wallet” light has just come on. I wonder why they use symbols like ASR/BAS and not just pound (or dollar) signs !
Do you remember the days when the most complex thing you can to do on a car was to take out the 'ponits' and give them a quick clean with a nail file !
All the best to all with fault lights 'a-glowing

You can turn the wheel with out the engine running. Remember that us Brits are made of though stuff and power steering is still considered something for whimps, like central heating, dish-washers and tea bags!
I think there is a bit of legislation somewhere that says that you must still be able to turn a car’s steering wheel even when the power system fails, all-be-it with the muscles of a super hero.
Thanks again for your advice, I’m in the middle of negotiating to sell a couple of my kidneys, once I have the cash I’m off to see that nice Mr. Merc !
All the best to all with warning lights glowing this morning.

I had the same problem a couple of months ago in my CLK. However, I also lost cruise control, so yours may be a different problem. Anyway, here's my post from mbclub.co.uk after I had it repaired:
Here's the breakdown:
A 001 545 01 09 Stoplight Switch £ 6.90
Labour £69.50
VAT £13.37
TOTAL £89.77
Expensive, but at least it's fixed. The bad news (that was the good? ), is that I need new rear discs and pads, approx. cost £240 .
At least they let me keep the old switch ...

Thanks for that info. A bill less than £100, wow, I'm surprised they thought it worth doing the paperwork for so little.
Actually I'm being a bit hard on MERC, so far my routine service bills haven't been too bad, the A service on an SLK is only round £120, reasonable for the type of car.
All the best
John :-)




You guys crack me up. I guess we all share this benz-love-and-hate affair.
