tSp's Bravo maintenance log

Hello all. Bought myself a lovely MJet 150 Bravo and plan to do a whole list of things to it. Thought I might as well share my progress in case anyone finds it interesting, has tips, suggestions or even spots if I've done something wrong (I'm mechanically pretty good but not done much on cars before). Here she is again:

Re: tSp's Bravo maintenance log

First: fuel filter.

Nice and easy to start out. on the Bravo the filter's easily accessible and up high so you don't even need to pull any fuses to drop fuel pressure. I just let mine sit overnight so it was cold, with a mostly empty tank. See pics - they match the steps.

Step 1: Disconnect the battery. Probably not even necessary, but I like to avoid any possibility of sparks and leaking fuel in the same space.

Step 2: Disconnect fuel lines and undo retaining collar. Nice and easy as they have pinch grips, and are suspended in the right position, so it's difficult to get them wrong when you reconnect, and the pich grips are oriented to make you take them off in the right order. The collar's not actually attached on the other side, just hooked in, so don't drop it.

Step 3: Put the plastic caps from the new filter over the inlet and outlet tubes of the old one as it's still full of diesel. Do the first one slowly or the pressure might make the second squirt. New filter is a little fatter, but everything's in the right place. Unclip water presence sensor connector from the bottom and remove the filter assembly from the car.

Step 4: Unscrew the sensor over a catch pan and let it drain. Remove the caps you put on the tubes so it'll drain faster. It holds about 4-500ml.

Step 5:Screw the water presence sensor into the new filter until it's snug. Careful not to strip it as it's plastic-threaded.

Step 6: Follow the steps in reverse. In this case, the fatter filter meant the collar didn't fit neatly in its initial position, but the end hook is stepped to accommodate larger filters, so I just moved it out tot the next step. Well thought-out design!

Step 7: Reconnect the battery. Get in the car and turn the ignition to ready position so that you can hear the fuel pump running. It's gurgle and grouch for a bit as the system re-fills with fuel. Do this a few times, until it stops bubbling.

Final step: Start the car, check for leaks. If your car's telling you 'ASR disconnect' and 'Hill hold not available', that's because the battery was disconnected. Just drive a few feet and it should remember what it's supposed to do. Done! Now mark the new filter with the mileage when it went in.

Great success! Just from driving forward a few metres and reversing back up the slope I am pretty sure it had been losing power at low revs, because it felt a lot smoother on the clutch while reversing slowly. Cleaner fuel delivery should also mean it has a little more power, and stops straining the fuel pump.

Re: tSp's Bravo maintenance log

On closer inspection.. you only have 2 pipes connected.

On the punto there is :

Inlet(from tank)

Outlet ( to HP Pump)

And a return line to the tank.

But routing is easier..as it is mounted on firewall : bulkhead.

Re: tSp's Bravo maintenance log

I've been looking for a replacement key fob badge since I got my car, because the stock one is wrecked, but I could only find those ones stamped out of coke-can thin aluminium that look s*** and bend as soon as you put them in.

Then I found a FIAT lapel pin being sold by jbcarspares on ebay, on a hunch, asked him to measure it, and I was right... it's the OEM part with a pin welded on it. It still even has the locating pins. So, dremel, tape, and done. Much better!

I was hoping to share this as a source of replacement badges, but it seems the listing has ended. Anyone looking for a badge though should try jbcarspares and ask if he can get more in. There is another 'official' lapel pin too that looks cheap though, so take care.

Re: tSp's Bravo maintenance log

OK: today's mission is to diagnose and fix my car of one clear fault and two worrying signs.

Symptoms:
- Some white smoke (?) at low revs, not at startup, gone when the engine has warmed up.
- Low coolant levels when I received it.
- Engine light, with fatal error code P010F - Mass airflow sensor A/B correlation.
- Some slightly weak performance climbing hills in low gears, though it seems to shift on the flat. Hard to tell, as I haven't had the car long enough to tell what is normal.
- Tendency to stall more easily than it should.

So, 'head gasket' was definitely on my mind. The MAF fault gave another possible explanation though. I connected to multiecuscan, and looked at the parameters. What stood out was an air demand of 710 whatevers, and a supply about half that, scaling with revs.

1. First things first, got it into the barn and up on jacks. Belt and braces: handbrake on, car in gear, axel stands, a scissor jack and a hydraulic jack all holding it up. Give it a good shake to see if it moves at all. Nope: it's not going to crush my head. Good.

2. Take off the engine undertray/skid plate. This step is in the repair manual, but it's not actually necessary, it just gives you easier access. Still, I wanted to have a look as I haven't properly inspected the engine before. All the bolts are mismatched, some are screws, some are cable ties, and one bolt is stripped bare but the plastic around it is completely mashed from someone's attempts to get it out. Never mind, it still keeps water out and doesn't rattle. Because the back two bolts are replaced by cable ties. I can just leave it hanging rather than take it completely off.

3. The MAF sensor is on the front left. Disconnect the battery negative, then the MAF's cable connector: use a screwdriver to lever up the yellow clip, then pinch in the black part it was tucked into, and wiggle it loose. Don't pull it by the cables! It's on hard and in a tight spot, so not easy.

4.Having a look underneath, I find out two important things: one, look! A coolant leak! It looks minor, and gives an explanation other than head gasket failure for the low coolant levels. The second point is that one of the retaining clips on the air box is rusted to s*** and wasn't fastened, allowing debris to get into the air system around the filter. This is looking promising.

5. From the top, loosen the jubilee clip that holds the air intake hose onto the MAF, then loosen the hose.

6. Undo the two bolts. This is really tight, so I used a tiny ratchet to break them loose, then a u-joint adaptor on a long 10mm socket to undo it. The adaptor gave a bit more leverage than just fingers would.

7. Work the MAF loose and take it out. Great news! It's covered in s***! That means it probably is the root of the problem, and it's not a faulty sensor. The MAF is a mesh of wire whose resistance decreases as airflow cools it, so being covered in mank and dust would make the ECU get the fuel mix wrong. I used a whole can of EGR cleaner (you need a spray that is intended for cleaning electronics and leaves no residue). For bigger bits, grass seeds and leaf fragments, I used a cocktail stick to poke it loose, and blasted it out with the spray, agains the usual flow direction. Be careful not to damage the mesh.

8. Waited for it to dry completely, and took the opportunity to change the air filter. This is really difficult unless the MAF is off, because that whole assembly pushes on the air box lid, stopping it from opening. Make sure the rubber gasket is oriented the same way (rubber to the right of the car, foam to the left). Fixed the rusty clip, reattached everything (new bolts where possible for the undertray, wire-brushed, rust-treated and re-tapped everything that needed it) and dropped it back down.

Success! Cleared engine code did not reappear, and multiecuscan reported air demand and supply as both being about 400 at idle, and remaining pretty much in step right up to redline. No smoke of any colour. Ran out of time, but can't wait to take her out for a drive and see if it's found a bit of its missing power!

Re: tSp's Bravo maintenance log

Another point: spotted an oil leak while under there. looks slow, no drips. Leaky sump? Transmission? What do you reckon?

Re: tSp's Bravo maintenance log

That looks like it's coming from your gearbox. Drive shaft seals possibly. Get it checked as soon as you can. You don't want to run your gearbox dry.

Re: tSp's Bravo maintenance log

You're the second person to say that now - you're probably right. I know the o-ring on the MAF sensor just snapped and fell off, and that probably got put in the same time as the drive shaft seals.

Edit: had a look in the repair manual and there is actually a dipstick for gearbox oil - didn't think there was. Will check this ASAP as engine oil levels are OK, but it may have been topped up before the sale. That'll tell me where it's coming from.
