    Noob with a few problems

    Hi all, I've owned my roadster for a few months, it drives pretty well but it has a few problems I can't seem to get my head around that I hope some of you can help me with as follows:

    The wipers stopped working in heavy rain and haven't worked since, doesn't seem to be the fuse, any ideas?

    The forward o.s indicator is cracked, I bought a replacement but the washer bottle is in the way, how do I access?

    It has developed an oil leak, it has always been a git gungy under the boot tray but it has started to drip on my driveway. Leak is near side.

    On the plus side, genuine parts are really cheap from the Mercedes dealer, repairs have been easy to do so far and it's a great little thing to drive.

    Thanks for any help.

    sign up to www.evilution.co.uk as it will be invaluable

    urgently check for leaks (wiper tray) because if there is water in there you could be looking at a big bill

    Try http://fq101.co.uk/how-to-guides/fortwo-452

    Your oil leak could be drive shaft seals ?.. or the turbo area ? or even positive crankcase pressure causing it to blow out from dipstick etc ... you need to get under and narrow it down to a particular area.

    and here for the probable root cause of your wiper motor failure - and potentially more problems

    Thanks for the links, I suspected that I'd have to remove the front wing to get at the indicator lens and will pull the scuttle tray apart and clean out that area.

    Can I ask, are these prone to positive pressure? I have been suspecting that the oil leak and gunging is from the top of the dip stick, there is a lot of mess in this area. The driveshafts are lower than the leak, unless it can crawl upwards.

    OK a few things to factor in here... firstly there are virtually no Roadster owners on this forum - the answers above are from forfour and fortwo owners and whilst not necessarily bad advice, may not be quite right for you as a Roadster owner. You should get registered at www.theroadster.net and get acquainted with the folk on there as that's where you'll find the Smart Roadster community.

    The wipers will almost certainly be a failed wiper motor. There's a small possibility it is a wet SAM unit, but unless you're getting other electrical shenanigans then it's far more likely your motor has seized.

    The indicator is a bit of a mission to replace - best route is in from underneath - then buy some paint protection film and cover the lenses with it - it prevents future damage from stone chips.

    Most likely your leak is from your sump which is very likely rusty and porus. A new sump is about 30 from Merc - paint it with something decent to protect it before fitting and it should last longer. Don't be tempted to buy an aftermarket one with a drain plug, they're not worth it, pumping the oil out with a PELA pump is more efficient and extracts more oil so keeps your engine in better condition.

    Sumps when they leak are OS.
    And can be a PITA to replace. Check for other possible sources of leak before diving in.

    Rather than taking the wing off, you really need to take the whole front end off as the wings are clipped to the centre panel and it would be very difficult to get to these to remove a single wing.
    It's a pain to have to do so much dismantling but it's not very difficult, just dozens of screws. Helps to have an assistant when removing the front end as it's a bulky, awkward shape for one person to handle, though it doesn't weigh much at all.

    Yes! The PCV valve is very prone to clogging up with age and sticking open. When that happen boost pressure from the inlet is free to leak into the crankcase. The valve isn't too expensive (though 17 for a small plastic valve is a bit steep IMO). It connects from the throttle body into the crankcase at the front of the engine (i.e. the side that faces the front of the car). The throttle body connection is very easy to see and change, but the one on the engine is a nightmare unless you lower the engine on it's mounts, or have very tiny hands. It's possible to cut the rear pipe and join it to the new valve with a piece of flexible hose so you don't have to touch the engine end of it.

    I'd definitely suggest you spend a tenner on a subscription to Evilution. It's a mine of useful information, even if the occasional rants by the author in the articles make it rather less professional than it could be

    That said there is a good guide to removing the front on fq101.co.uk
