Help! Advice Please

[Old Jock]

I have found a 2005 CLK 350 which I want to buy. Unfortunately, it has the yellow engine alarm on the display. It also has a rear parking sensors which is either missing or has been pushed back through the mounting hole in the bumper. The seller says that it is the parking sensor problem which is causing the yellow engine alarm as they happened at the same time. Is this feasible? I have a basic Autel Maxiscan obd2/eobd scanner which only shows engine faults, will this work on a Mercedes? It might at least let me know if the fault is engine related. Any help and advice will be greatly appreciated.

I very much doubt a parking sensor issue flags up an engine management light buddy . Where do you live , maybe a quick inspection at a Mercedes independent will show up issues .

Post a link of the car

Hello and welcome,

That's some "artistic licence" the seller is using there...

Engine warning light relates to the engine not to parking sensors...

 

[Old Jock]

Hi guys, Thanks for your replies. I agree with Blobcat and Wighty that it's unlikely that the two are associated. Do you think my basic engine scanner will work with a Mercedes? Does a Mercedes use obd2 protocol or a proprietary one?

EML is the engine management light, are you sure the yellow lights are not the parktronic lights because of the parking sensor, just thinking outside the box!

Hi mioba, Thanks for your reply. It's the engine warning light which is on. Where is the proximity sensor indicator, is it in a small binnacle above the centre of the dashboard? If so, I got that indication during the test drive just as I came to a halt at a road junction. It only happened once and cleared as soon as I set off. Would the engine light come on if the car needs a service? It hasn't been used for a while apart from taking it for an mot about a month ago.

The row of yellow & red leds on the centre of the dash is for the front parking sensors, the same row of leds can be found usually above the rear window for the rear parking sensors.
The parking sensors & engine warning light are two separate things, as Blobcat says, the seller is trying it on.
The engine warning light is flagging up a fault and is again separate from any service warning messages.
Your Autel code reader might very well talk to the car enough to get any generic engine codes, but as Wighty says, there are more Merc specific code readers.

Be very careful when buying one of these with the M272 V6 especially 2005 it's right in the range for the dreaded and very expensive balance shaft problem. Even if the warning isn't for cam timing walk away and find another 2007 on or pre 2004 with the different engine.
Check out the engine number from this link.

engines up to #2729..30 468933 -- this when the gear is the problem

engines up to #2729..30 759427 -- this when the adjustment solenoids are the problem

engines up to #2729..30 895140 -- this when the adjustment solenoids leak oil

The first two scenarios cause "check engine light", the third is just an oil leak.

Hi EmilysDad, Thanks for your reply. I'll go back with my obd2 tester and see if I can view the fault codes.

Hi Oldspanners, Thanks for the information. The car has only 84,500 miles on the clock and has been cossetted by the owner, is it likely that the problems will appear at such a low mileage? I'm new to Mercedes ownership so know next to nothing about the pitfalls.

ps when I tried to open the mb world link I got a message saying it couldn't be found.

Not to worry the vital info is in my post ie the engine number range. Get the engine number and check it.
But my advice is to walk away it's not worth the gamble.

Read up about it, it can occur at any mileage some as low as 40-50K but it doesn't occur in all engines as it was a quality supply problem. But for me it would be a gamble I wouldn't take and the thought it may happen would always be in the back of my mind. It's an engine out job and about £1,500 from what I remember.
I don't know what the price of the car is but there are more out there newer and older that won't have that risk attached.

EML can me be one of a many things and everything can be repaired. Just sit tight till you get the codes read.

The problem with the balancer shaft is that it could occur at any time and make repairing the car uneconomic.
It's a gamble if you want to take it with a few £1,000's of your money O.K. but why bother?

Supply quality problem? Seems quite a bit of that on this Marque theses days.. on the car referred to by the op. U have been advised to walk, I sure would. Just normal maintainenance on these cars can be a ballache. Don't buy a "supply quality problem".

 

[Old Jock]

I found codes p2006, intake runner control stuck bank 1, and p0410, secondary air injection system. Cleared the codes, revved a few times, let it idle then revved again and the faults didn't reappear. Would these faults be consistent with a car which hasn't been used much recently?

Maybe an Italian tune up is required buddy ?

My thoughts exactly! I know that it hasn't been used much in the last six months or so apart from taking it for an mot in August.
