  1. Hi all,

     

    I've noticed this odd noise on the Mrs' car that is getting steadily louder. I first noticed it at the end of last summer and I'll try to get a recording off it but it varies with engine speed and sounds more like a "whup whup" noise than a "tap tap". At higher revs (above 1000?) the noise is not particularly evident. Not sure if it is a tappet or water pump, perhaps? 

     

    The engine has done about 69k (1.2 TSI 86) and has had regular (6-10 month) oil changes due to it being used for short trips.

     

    Any ideas? 

     

    Cheers.

  2. I like mucking about with Arduinos and fancied knocking up something I can use as a data logger for things like

     

    Water temp

    Battery voltage

    Oil temp

    Throttle pos

    Engine load

    Fuel consumption

     

    I know the car displays some of these already but the mk2 my Mrs has doesn't and I'm just interested in knowing a few things about what's going on.

     

    Has anyone tried to use obd2 to log before and which pids are in use?

     

    Also, on my old Focus, I had some information from a mate that worked for Ford so I could decode the canbus traffic directly (I have some tools for this). Is anyone aware of doing this? The decoding information usually comes in the form of "Vector .DBC" files if this helps to know what I'm really asking for 😉

  3. Interesting topic.

     

    I'm on my original battery (2017 car) and have been expecting to have to replace it at any time now.

     

    I think the battery is an Exide.

     

    I was looking on Tanya for a replacement the other day and saw that they were a lot cheaper than when I last checked. A Varta EFB027 640A is £108 and I'm sure they were £200 last time I checked (maybe during COVID).

     

    I couldn't check the link but does the battery really need to be coded to the car or is it really to reset the BCM?

     

     

     

     

  4. Hi,

     

    We had a bit of rain over the last few days around here (roads flooded etc) but when I closed the hatch on the combi, this morning, I heard an unusual sloshing sound.

    Tipping the hatch to a certain angle allowed water to, well, somewhere between pour and drip out of the lock latch, which I did until it emptied.

    There's a little rubber bung just next to the latch, which I guess should allow water out but, when I tried to see if it was clear, it disappeared inside the hatch.

     

    Is this a common problem? Anything I should be doing to prevent it? 

     

    Thanks in advance.

    I doubt it, I think you're worrying too much and definitely overthinking things.

     

    The absence of oil pressure doesn't empty the system, the tappets stay full apart from the two or four that are under valve spring tension and the tensioner piston simply relaxes until oil pressure is restored, whereupon, like any hydraulic system, that pressure is transferred almost immediately throughout the entire system.

    I usually do overthink things, to be fair. Thanks for the explanation

    No, from what I've read in other sections of this forum, an issue can arise if the tensioner is past its best, and the vehicle is allowed to roll backwards with engine stopped and in gear. Apparently this can result in the chain jumping teeth on the chain sprocket. 

    That's interesting. I guess that could happen if someone rolls off ramps after an oil change and gets into this situation.

    Hello, I would say that this will not be an issue, as you say, the oil will drain back from the tensioner while the engine is stopped. Just refill and restart as normal with one proviso - don't ever permit the engine to turn over in reverse direction while the cam chain tensioner is unpressurised. 

    In reverse? Would this be with a spanner on the crank? 

  8. Hi,

     

    How long can the (2014) CBZA engine be left without any oil in it? 

    Is there an issue with the cam chain tensioner draining and the chain skipping on start up if the engine is left without oil in it for too long?

     

    On one hand, this seems unlikely as the oil will drain out into the sump, over time, anyway but I'm just double-checking.

     

    If so, this seems to be a poor design if you were doing a job  on the engine that meant it was without oil for a few days or more. 

    What is the procedure for dealing with this? Do I crank the engine with the plug leads removed from the coil pack to allow oil to circulate before I start it proper? 

     

    Thanks in advance.

  9. I was looking to use a wireless adapter but wasn't going to be paying £50+ for one (e.g. Motorola offering), so the AliExpress item looks like a decent price.

     

    Does it come with a separate usb lead? I've had trouble recently with longer USB leads and Auto and I wondered if the wireless adaptor is maybe using a lead that is longer than 1m? 

     

    Auto never used to be so sensitive to USB leads as recently but I updated the Bolero and my phone at a similar time so I'm not sure what the culprit is.

    Hi all,

     

    I found this thread half way though changing oil and filter and am maybe glad that I did.

     

    I'd bought a Bosch filter the other day, with the correct part number for the CBZA.

     

    The part number on the box suggests it is correct. Part number on the filter matches the box and is "Made in France." (Who manufacturers filters in France at the moment?)

    I didn't look too closely at the filter until changing the oil earlier when I put it next to the Mahle it was replacing (below). The Bosch filter is a little smaller and doesn't have the "shoulder" seal like the Mahle.

     

    So, I guess these possibly incorrect filters are still in circulation (mine came from Amazon).

     

    I've ordered a Mann, like I should have in the first place, and I guess I'll get in to customer services to see what they have to say about it.

     

    I guess the filter may be perfectly correct and maybe it was just a coincidence that someone had an engine problem with this filter fitted but I'd rather not find out the expensive way that it isn't.

     

    Thanks for the heads up @xman

    Thanks, was undecided on best place to post. 

    Maybe you saw it already but I emailed Skoda recently and was told it (belt and tensioner) was now "lifetime" which I've taken to be 10 years/150k+. 

     

    I was going to have it changed next year but will leave it.

     

    I've the same year/engine (1.2 4 cyl 90)

    I hope it's not too late now, but this is what we bought for our 2016 1,2 Fabia from Opie Oils. I can't remember the cost as bought last year, along with oils and filters for my Fiesta. The oil is what was recommended on Millers oil website. Paid a little extra for the 'nano-drive' stuff and came in 1l bottles. Wanted a Mahle filter but Opie didn't stock one, so had Bosch instead, (bought Mahle for mine).

    The Mahle filter I bought last time had Made In China on it so I went for a Bosch this time, which had Made in France on it

    I've also ordered oil and filter early for mine and the Mann filters were half price so I went for one of those. Hopefully, it'll be made somewhere sensible.

     

    I'm not averse to buying Chinese goods; I'm typing this on a Poco (Xiaomi) phone but I do try to support local-ish jobs where possible.

  13. https://www.tyrereviews.com/

     

    Lots of good info on here including results of German tyre tests.

     

    A contractor at work used to do tyre testing and always recommended Kumho for everyday tyres as they were a decent quality vs value proposition. 

     

    I used to buy Hankook as they used to come in just behind the premium big boys (Conti, Michelin, Pirelli etc) but weren't premium prices. 

     

    More recently, started to use Kumho on both Fabias  and couldn't really tell much difference between them and Hankook.

  14. I did this job yesterday. It was pretty easy to do.

     

    I removed the air flow pipe from between the turbo and the throttle body, following the guide. It needed a Torx screwdriver bit to remove from the turbo end and a bit of manhandling to get it off at the throttle body end.

     

    I poked a thin hooked wire into the grommet and dragged it backwards; this  found that there didn't appear to be any remnants of the old, broken off plastic PCV still inside it. 

     

    Then, I removed the old grommet with a flat blade screwdriver.

     

    I didn't bother softening the new grommet as it seemed to fit easily into the rocker cover, then pushed the PCV "snout" into this.

     

    Seems to all be ok.

     

    Parts were about £26 delivered from AutoDoc as no one else seemed to have both parts in stock.

    For once we seem to disagree - the price is about right but I prefer Mintex branded stuff for those!

    I work in the automotive sector, often with Bosch, so I see that they generally offer a decent quality/value proposition. 

     

    I used to go to the Ferodo factory at Chapel years ago so I used to buy their kit for a while.

     

    I've never tried Mintex stuff to be fair!

    FWIW, as I mentioned in another thread, I did FINALLY (but only at the 2nd attempt!) get through on the phone to a "real person" at Skoda UK Customer Services about an hour ago and was promised some sort of reply today - I can but hope!

     

    Skoda UK got back to me today.

     

    I posed the question: "Does your previous advice apply to the cam belt tensioner and any other related components, too?"

     

    To which they replied, "I can confirm that nothing needs to be changed regarding the parts of the cambelt."

     

    So, there we have it.

     

    Maybe the engineers have enough reliability data now to allow these statements to be made or maybe it'd be wise for me to get the cambelt checked at about 65k miles (like I did with my Focus) and make a decision from there. I guess there's less to go wrong on this engine as the water pump was cam belt driven on the Focus lump and I believe that the CJZC's water pump is driven from elsewhere.

    That's a good point (for a change) - so does anyone have any other comments about the life of the tensioners on the TSI engine?

    Indeed.

     

    Since I appear to have access to the Skoda UK "Commissioner Gordon" hotline, I've asked if their statement also applies to cambelt related components, such as the tensioner.

    Interesting:

    - via the PM system, it seems that we both used the same  address to email at Skoda UK - but I have yet to receive any answer from them. Go figure!

    - Now that you have corrected the engine type, it seems that our car DOES use the same engine (CJZC), and yet one (yours) is the 110bhp version but ours is the 90bhp version! So why is that as I would have thought that they would have been given different codes?

    - However, assuming that both engines are inherently the same (but probably with different maps to get the power difference) then ours should also have the same lifetime belt (15 yrs or 180k miles) recommendation!

     

    Therefore thank you for all the info, and I hope I do soon get a reply from Skoda UK to confirm the latter (very important!) point!

     

    Mine is the 90bhp version, too. I guess the 110bhp has a different code?

     

    I don't know if the only difference is a remap although I know you can remap the cjzc to a higher output  This is hazy but I might have read that the turbo is different, too? 

     

    I don't know if the 90BHP is a detuned(/less stressed) version of the 110 or the 110 is a tuned version of the 90, if that makes sense, but it'd be interesting to find out
