I tried to start the engine when it was already running a few times when I first had a Jazz,  soon learned to look at rev counter rather than rely on engine noise to see if it was running.
Done that now and again myself. It is a remarkably quiet engine, considering there is not a lot of sound deadening in the cabin.

Did it today. Coasted to a mini roundabout, forget to change down, went to pull away, thought the engine had stalled but in fact it was still turning over. Pleased to say it is a rare occurence but I do get caught out every now and then if I am not paying close attention.

Honda Jazz Mk2 2008-2015 / Re: 09 Jazz 1.4 i-shift ABS Pump continuously running
« Last post by Spike on May 19, 2019, 10:14:31 PM »
Bit of feedback as no replies. Continuous running of ABS pump continued, along with new issue of intermittent Power steering and transmission MIL coming on. Even though vehicle would start OK, turned out to be low voltage. New battery fitted, charging was/is OK and presto all fixed.

Hope this helps

Honda Jazz Mk1 2002-2008 / Re: Water in boot

Hi Bagpuss,

This is a common fault, there are previous posts about it. The water gets in under the plastic strips along either side of the roof, there is a sealed panel joint under the strips and with age the sealant splits slightly allowing in water which runs down unseen from inside the car into the spare wheel well.

It is a very easy fix, just remove the strip (usually the driver's side but could just as easily be the passenger side) and seal it up like you would seal the edge of a bath. I used "Nemesis grabs and seals" from Screwfix which was about 5. There is lots of advice not to use ordinary silicon sealant as it doesn't last. I did mine last spring and it is still fine.

My dealer charges 35 for MOT if in conjunction with a service, but 45 otherwise. 

That is a bum deal my dealer offers free MOT for life provided you have it serviced by them annually, both on my Jazz and now the Civic.
Thats my kind of price Hobo, except Cornwall is a long way to travel from Lancashire!
Anyone else nearer home with that kind of deal?

Thanks.

Sound Deadening Part 5: The Roof and Boot Lid

So the next big job was the roof (which turned out to be the easiest part to apply the sound deadening to).

In the service manual it says in order to remove the roof liner, you have to remove all the rear plastic trim, side trim, as well as the grab handles, sun visors and ceiling lights.

But seeing as it's fabric basically, I was convinced I could remove it by only doing the grab handles, visors and ceiling lights and jut pull the fabric over the plastics to actually remove it, saving me having to remove all the plastic panels again.

And it worked:



The roof was really easy to apply the Silent coat panels to, as it was basically one long flat panel:


I drove around like this for a few days until the closed cell foam sheets I had ordered arrived, and I hadn't realised just how much sound the roof liner on it's own actually removed.

10mm Closed Cell foam sheets arrived:


It actually worked out a lot more cost effective to order them in 1mx2m rolls. I ended up ordering 3 of them in total, which only cost me 36.

It was quite hard to work with them in large sheets compared to the smaller 50x30cm sheets I was ordering before. But I managed to get there in the end:


Putting the roof liner in was a lot harder than I was expecting.
Getting it off without removing the plastic panels was fairly easy, but getting it on was not.
I did end up slightly damaging part of the roof as I tried to bend it in to place:


But apart from that, there's not really any other damage.

The only noticeable area where the liner doesn't fit quite right because of the foam underneath is around the main interior light, where there is some noticeable stretching:


I did notice quite a big difference after doing the roof, but it only seemed to make all the places noise was getting through more noticeable. But overall the car is a lot quieter.


Next to do was the Boot lid.

It was easier to work on from the inside with the boot closed:


The Silent Coat added quite a bit of weight to the boot lid, and made the boot a lot harder to open. Luckily Honda installs a metal weight to the lid so it doesn't fly up too quickly, so I just removed that metal weight and it was basically back to normal again!

Next was the 10mm Closed Cell Foam


And then the foam installed to the plastic cover:



One small little detail that I really noticed and had to fix, was that the parcel shelf rattles when you go over bumpy surfaces, and I never really noticed it before until I made the car quieter, and now it drives me nuts, so I had to fix it!

I applied some silent coat to the areas causing the rattling, and added some closed cell foam to silence any rattling coming from the parcel shelf touching the rear plastic:



Slightly OCD I know, but it really stood out after the car became quieter and now it's rattle free!


Next stage is going to be doing the front inner wheel arches from underneath. Which means removing the front wheels and the wheel arch plastic trim. As I still get a lot of road noise front the front wheel arches. I currently have Bridgestone Turanza ER370's on it, which came from the factory. They are rated at 68db, which seems the lowest rating I can find for tyres for the car, so I don't know if changing them for some Yokohama BluEarth ES32's (which are also rated at 68db) would make any difference to the road noise from the tyres or not.

And I'm going to try and remove the road noise caused by the door seals.

I did notice quite a difference by simply removing the door seals and re fitting them properly with a rubber mallet.
But I saw on another forum someone used some PVC rubber piping and ran it through the standard door seal to create a better seal when the door closes, and they added some extra adhesive rubber door seals to each door to get the gaps the standard ones don't get. So I've ordered some PVC rubber piping and some adhesive door seals and I will take it from there.

So watch the space for those!

Have to say I'm impressed with the time and effort you're putting into this. Not just on the car but sharing the results here. Thanks.

Very interested to see what a difference the roof makes. It's a big resonator (sounding board) so could make quite a difference. It did cross my mind whether the handling change could be because the weight you added (half mine!) was low down. Obviously not so with the roof. I think there's an argument for only using a few random patches of the heavy stuff - it would spread the resonant frequencies and so reduce booming - and close cell the lot to dissipate energy. Might give some thermal insulation too. This the first proper warm weather since I got my Jazz and it does have a lot of solar gain.

Thanks springwood. I wanted to share it on here for others to get ideas for their build, and to hear what works and what doesn't etc..

The roof did make a big difference, sort of. Doing the roof cut basically all of the sound coming from above, which felt really unnerving at first, as it was so quiet from above. But there's still sound coming from all other directions. I think at some point I'm going to have to say, I can't get it Rolls Royce quiet!
I think a lot of the sound is coming from the windows, which I can't really do anything about.
But I have a few tricks up my sleeve I want to try!

I have also noticed the car's stance is slightly lower, so the added weight done the job of lowering springs which is nice!

What did you do to your Jazz, sound deadening wise? I couldn't find anything in your posts.

My thoughts have been the tappets/valves need adjusting. There are a lot of old posts on this topic and a lot of mixed opinions about it, ranging from they are essential maintenance that should be performed to keep the engine running properly, through to they never really need adjusted for the life of the car and you're more likely to introduce problems disturbing the engine gasket seal. Honda do however list it as a service item (I can't remember the mileage interval).

The original tappet check / adjust was every 25,000 miles and Honda used to charge over 300 for it.  All our MK1's did over 90,000 and one did 120,000 without even having the tappets checked, let alone adjusted ( my first Civic did 190,000 without a spanner on the engine except cam belt change every 60,000 ).  I think because the cam and tappet arrangement on 8 valve i-DSI engine was so different to anything Honda had done before they played it safe and specified 25,000 mile intervals.  In any case I think a noisy tappet is a happy tappet, a few fractions of a mm less valve lift is hardly going to affect performance,  it is when gap closes up and they go too quiet they can stop valves closing properly that valves get burnt out - which is a much bigger problem than a bit of noise.

The fuel injector solenoids can emit quite a loud ticking noise,  easily audible with bonnet open but if you have good ears maybe inside car as well - the rest of the engine is normally so quite I tried to start the engine when it was already running a few times when I first had a Jazz,  soon learned to look at rev counter rather than rely on engine noise to see if it was running.

I have the exact same sound, exactly as you describe. My engine is aprox 80K miles.

The sound is fairly subtle, and if you're not listening or mechanically aware I'm sure most general owners wouldn't even pick up on it as a fault.

The only difference is I haven't noticed it starting when the engine cold light goes off. I've just been aware the car does it for a while until everything is well warmed up and goes away.

I have also completed regular servicing including all 8 spark plugs and fuel cleaner additives without any effect.

So far I've just left it. I will keep following this thread..
