Kwik Kwestion: Will "Check" dash light fail my MFK?

What more is there to say? I'll find some more...


Ever since I bought my car 2nd hand (6 years ago) there has been a dashboard warning light coming on every now and again. The drives fine, it's not causing a problem.


I checked this in the UK at my local garage, only one sensor at the time with a cost of about 60 quid + fitting. I had it checked at a local garage last week in CH and they confirmed it was two exhaust sensors, both need replacing. They want the princely sum of 350CHF each to fix.


Clearly this is expected daylight robbery that I'm happy to avoid and I've been living for the light for 6 years, so I can handle it. However, as I've just moved to a new Kanton, they want me to renew the MFK (and after 6 years, I can't really complain).


But will the Check light cause it to fail?

Re: Kwik Kwestion: Will "Check" dash light fail my MFK?

Sorry, I can't answer your exact question...This is going to sound silly, but have you tried replacing the gas cap? I've had the check engine light on previous cars (in the U.S.) and the local shops always recommended replacing the gas cap first before doing anything drastic. I guess they get worn out over time and don't seal properly, so sometimes they let too much fuel evaporate and set off the sensors?

In my case both times a cheap gas cap fixed the problem and the light went off after a few more starts of the car. Might be worth a try?

Re: Kwik Kwestion: Will "Check" dash light fail my MFK?

As these are exhaust sensors, it might be that your 3-way catalysator is failing.
You need an up to date pollution (Abgass) test to pass the MFK so maybe yes, you probably need to fix them.

But if it fails the MFK you still have 10 days to fix it, before the (free of charge) second test. Have you thought about taking the day off and driving to Germany and get it fixed there? You can reclaim the 19% German sales tax.

Re: Kwik Kwestion: Will "Check" dash light fail my MFK?

I assume a gas cap is the same as the petrol cap? If so, my gas cap is at the back of the car, not near the sensors, would that make a difference? The light comes on at completely random times, sometimes perhaps when I'm going along the motorway on a long drive, so I doubt it's that.

But I'll do some research on that anyway, thanks for the idea!

Re: Kwik Kwestion: Will "Check" dash light fail my MFK?

I did think of the German option originally, but I decided it's not worth my time to take a day off to save a few hundred CHF. I guess it's a reasonable option to take it to the MFK and see what happens then? "Ready, Fire, Aim!" (My favourite saying.)

Yes, sorry. Petrol cap or the cap where you put in the fuel. Do a Google search for "check engine light gas cap" and you'll see lots of info about it. From what I understand the sensors measure the whole system, so they don't have to be near the cap to do their job. It could still be the sensors are the problem, but were I in your shoes I'd try the cap first.

Re: Kwik Kwestion: Will "Check" dash light fail my MFK?

I wouldn't try the petrol cap at all.

First get a fault code read out get tbe fault codes and then look what it is otherwise you are pissing into the wind at night jabbing at things with a short blunt stick.

I think a piece of black insulating tape over the offending warning light will solve the problem nicely .

Yes and...+1 get the fault codes looked at with a OBD2 reader. You can buy cheap ones off ebay for around 30 quid. They wont diagnose everything but it will give you an idea for the standard stuff. Plus the garage cannot charge you 50 quid each time you need a code.

I guess these are Lambda sensors you describe which control the air/fuel mix. At minimum you will use more fuel at worse (dependent on which one) you can destroy the exhaust catalyst by dumping too much unburned fuel on it. = Expensive catalyst replacement.

You could purchase the sensors yourself if you know which ones are at fault they are usually quite cheap to source and easy to repair unless they have become "welded" into the exhaust. Think 300+ Celsius every day all day for 5 years, you'd be a little tired of working after long.

Suggestion:- Approach a local independent garage get a 2nd opinion should be 500 chf max for all parts and labour. Swiss hourly rates are much higher and could be between 100-300chf the garage choice makes a difference.

Sidenote:- If these lambda sensors are engine side they are more difficult to change in some cars due to access and could be more to replace.

As someone has suggested an "abgas" is only applicable to cars around the 2004 or before year mark, so if the car is newer than this it's unlikely to need this test.

If emission test is not needed then no motor check light must light up during the MFK.

Here a possible trick to pass the MFK: Before the MFK unplug battery for some minutes, replug, you get around 40-80 km before the light comes back on (reinitialization phase of motor ECU).

Abgas tests are no longer required on modern(ish) cars that have on board diagnostic capabilities.

For the OP: pull the relevant fuse for the MFK.

Nice quote from the link: the OP is actually obliged to have it repaired in case the car doesn't need the test.

Quote:
Nach wie vor notwendig ist natürlich die Wartung des Fahrzeuges durch die Garage gemäss Vorgaben des Herstellers. Das Auslesen des OBD-Fehlerspeichers ist in der Wartung inbegriffen. Werden die vorgegebenen Ölwechsel und Wartungsintervalle befolgt, läuft das Fahrzeug zuverlässiger und die OBD-Leuchte erlischt in der Regel nach dem Anlassvorgang. Leuchtet sie jedoch auf, während der Motor läuft, muss das Auto zur Reparatur in die Werkstatt.

Mit der neuen Regelung werden die Fahrzeughalter verpflichtet, ihr Fahrzeug innerhalb eines Monats nach dem erstmaligen Aufleuchten der OBD-Kontrollleuchte reparieren zu lassen.

Re: Kwik Kwestion: Will "Check" dash light fail my MFK?

Hi All, thanks for all the lively opinions and info. I'll buy an OBD2 reader to get the codes, it'll be handy in the future. I've actually decided to go back to the UK and get the car fixed there, I have a local garage there who I trust. I need to go back to the UK anyway and the extra cost in fuel over a flight and hire car will be more that made up for in saved repair bills over here.


Have a great week!

Re: Kwik Kwestion: Will "Check" dash light fail my MFK?

So I went back to the UK and had my sensor fixed, and the ABS sensor redactor/tone wheel that was triggering the ABS light, they're fine now. Total cost was a few hundred quid all in.


When the car was on the ramps, I saw that the back brake disk covers were pretty rusty and starting to flake apart and, after umming and arrring, I thought I'd take my chances, leaving them as they were for the MFK. Hey, there's a 1000 rusty parts on my car, where do you stop?


But of course, that's what it just failed the MFK on. I've sourced them at the local Hyundai dealer what actually seems a reasonable cost and I'll replace them myself.


However, I'm going to run out of time to fix them in the 2 week retest period I have. What are my options now? If I go back, it'll still fail. Do I have to hand in my plates, or can just take the car off the road until I've fixed it and ready for another retest. Test centre is the Strassenverkhersamt in Wettingen.


Your thoughts appreciated.

Find a local mechanic and get him to fit them and live with the extra cost.

To take it off the road, you must hand in the plates.

That's not the problem, I can do the spanner work in a evening, the problem is the delivery time for the parts, they're not off the shelf from the dealer.

Guess I'm going to have to redo the MFK, show the guy the order note for the parts and see if he'll give me another chance a week later. (Or just pass it if I promise to finish the job
