Hi, I have searched the forums  and the internet but I cannot locate anything about the size of the Mk3 sump pluf and washer.. Any help please?
Ta, John

Which engine?  I've definitely posted here about sump plug and washers, and IIRC put up photos, for 2015 1.2 TSI CJZC engine.

 

I got fed up with chasing the washer and just bought ten factory fit plugs with integral washer, also available in 5 or 1 from someone on eBay, I can post a link if your engine uses the same sump plug.

 

Found the thread.  Photo below shows for 2015 1.2 TSI CJZC engine.

 

• N90813202 - is what I called 'factory' with integral / fixed washer and greater thread length
• N90288901 - is (shorter) sump plug only
• N0138157 - is washer only
• a suitable washer with IIRC 14 mm ID would do.

 

 

 

Another view of top plug c/w washer (different supplier).

 

 

 

An alternative set up plug and copper washer, plenty of combinations and singles choices out there.

The correct washer type is a crushable "rolled" washer, and not a flat thick washer, if you need one or some quickly, ECP sell what is a suitable version p/n 333771251,

 

That ECP part number lists the correct dimensions for these washer.

 

The VW and SEAT, at least, plan is, at the first oil change, bin the plug/washer combo and supply and fit a new plug N902 889 01 and fit a new one of these (N 0138157) washers to it.

 

I have, in the distant past, due to lack of local versions outside of VW Group spares dept, which sell the NO138157 at a high price, resorted to buying a pack of 12 or so - from China, they certainly look okay, exactly the same as the pricey genuine item, and for the past maybe 4 oil services, have worked very well on my wife's 2015 VW Polo 1.2TSI with the CJZD engine - then a mate asked at ECP and they sold him the item I gave the ECP p/n for, they look a bit "copperish" as opposed to the genuine item which might be an aluminium alloy item.

Thanks,

it's a 2016 tsi1.2 engine(90bhp) I took a punt yesterday and ordered 4 (14mm id)off ebay. I knew that I had come across a post about it a week or so ago but damned if I could find it.

John, I very much doubt if you'll have any issues just don't do the job like a lazy or oppressed professional  short of time and 'can-be-arsed'.  The washer that VW use is fine but I've used flat copper washers, flat other metal, crush type of both, washers on other vehicles for decades and never had a leak from the sump plug / washer / area, they are rarely  the origin of any leaks that drip from there.

 

Many service parts quality has dropped over the years and decades including I'd suggest sump plugs and washers.

 

Last month I used the first of the 10 febi (bilstein) plugs with fixed (flat) washer and I though by the look of the sump plug possibly it's made elsewhere than Germany, or like the quality of German cars have dropped.  I didn't notice any issues when checking  after a week or so of regular car and engine use.

I can recommend the Mann W 712/95 oil filter, I was impressed with it.

 

Cheers.

 

 

 

 

I'd guess that the "rolled" sealing washer will form a seal at a lower tightening torque than the flat sealing washers - okay the "rolled" sealing washer should only be used once and if you're careful the flat sealing washer can be reused as many people have found/done.

 

The sumps on many of these TSI engines are alloy, so achieving a good seal at a lower torque is desirable I'd think - though the lower sump pan plate on my 2011 Audi S4 is steel, and it's correct drain plug seal is again, a "rolled" sealing washer so - ??

 

Either way, a competent DIY "oil changer" should be able to deal with using either without damaging the sump threads.

I ordered a pack of 5 copper washers from ebay. Ordered oil filter(Bosch) and air filter + oil from Halfords and did the oil change on 26th. took air hoses off air filter housing but just could not lift the air filter housing off the 'ball' pins?  Seemed to be stuck solid and as this is the first time for me doing that job I was wary about breaking anything. Are the pin fastenins supposed to be that tight? Thanks, John

 

To me the air filter box is a right PITA farting about job and as with much VW and German engineering made more complex than needed.

 

Once you've taken all of the hoses off include the small one the air filter box just pulls up, you might need to lift one ball off at a time to wiggle the box up.  Bear in might there's a long drip tube at the front near the radiator when lifting out, then you need to turn the box over to take the hidden screws out and carefully prise the box open to get at the filter.  The filter needs to be installed and sealed correctly, I've no idea with the Tosch engine air filter but you get instructions with the Mann. - https://mann-hummel.com/content/dam/mann-filter/pim-assets/product-information/MFPI102_en_Installation_C_27_009.pdf

 

See this video. - 

 

ETA. before putting the very awkward shaped air filter box back on the ball pins you could try cleaning the rubber grommet things on the air box and put something like GT85, or silicone spray or small amount suitable grease and see if that eases reinstallation and hopefully taking the box off next time you need to. - https://gt85.co.uk/

 

I put the very awkward shaped air filter box on my small bench worktop to remove the hidden screws and it slipped off and scratched the plastic so place a wide and thick enough cloth/rag under the air box to stop it slipping or getting scratched, learn by my mistake.

 

PS I wouldn't take that front hose that has the rectangle air intake off at that end if you can avoid it as it's a loose flimsy fit as it is.

Thanks,

Yes I did take the hoses off before trying to lift the filter. I'll have another go at it at the weekend. 
John. 

John, let us know how you get on, I've only taken it off once or twice so may well have left something out or easily have forgotten (even if I'd done it 100 times).

 

You also need to remove that airbox to get at the spark plugs (so you might as well change, or at least clean, the air filter then too (VWŠkoda have the change schedule too far apart for my liking).  Having priced up the plug spanner and other bits I didn't have with the plugs I decided to leave it to the Dealership and as my wife has lost faith in the car she said she'd not have it 4 years later (to me it's got to be run into the ground for the price she paid for it s/h).

 

I used to try rocking the air filter housing after removing the air tube clips - these ratcheting pliers for removing these clips is a very handy tool to have, which I originally removed the air filter on my wife's 2015 Polo 1.2TSI, I just used a rack type tool that Laser tools sells, that worked well good, but not as fast to use as the ratcheting pliers for these big strong clips! Rocking the air filter housing allows you to build up confidence to get the housing up and off its mounting "ball studs".

 

For anyone with a later 1.0TSI engine, maybe a warning, there is a bolt to remove as well AND the filter outlet pipe to the turbo input has its pipe clip slightly out of sight at the back of the engine, our younger daughter and husband has a 2019 SEAT Arona 1.0TSI 115PS, and they are not "car people" at all, so they handed that car into a "proper" German car Indie garage in Bromley for its 4th service maybe 6 months after they had bought it, as the garage knew that they didn't plan to do many miles per year, that garage did not replace the spark plugs, but, they removed the air filter housing and opened it up to examine the filter element - which sounds maybe "fair enough", anyway, 3 months later they drove up to visit us in Scotland and I chose to keep that car's service parts change to what SEAT advise, so I replaced the spark plugs. After checking up on what differences there were wrt air filter fixings, I released both air pipe clips and moved them up along the pipes, and after rocking the filter a bit I lifted it up and off the car, as I moved it to the side to place it down in a safe place, there was a noise of something dropping off that housing - half of the tube that couples the filter to the turbo had come off with the filter, but as I had also released the clip it was only just able to stay with the filter - but that should not have happened as that tube should still have held together with its other half which was bolted onto the turbo inlet!  So, it looked a lot like that the previous person to lift that filter housing, did not actually release the clip on that output pipe, and just forcibly yanked the air filter housing upwards and in doing that disassembled the outlet pipe assembly!

 

I couldn't re-assembly that outlet pipe assembly that day, and the car was needed back in use and driving back down to London a day later, so it had to survive for a month or so in that state until I bought a new pipe assembly, sent it down to them and got them to get maybe the same garage to swop them over and request that the original parts were left in the car.  When we next visited them, I collected the 2 parts of that pipe assembly and took them back home, where I discovered that these 2 parts could actually get pressed/forced/snapped  back together - so if anyone discovers that this has happened,  you should, given enough time, be able to force the 2 parts back together!

 

The outlet pipe on the 1.2TSI engines, at least the CJZD version that my wife's 2015 car has, has a simpler and easier to deal with air filter outlet pipe which from memory is a one piece assembly.

 

Edit:- "from" not "form" !!

Exactly, I stopped being a source of "looked after 4 year old cars" many years ago.

I spoken with a wife's friend today who'd had coolant leak on her 2019 SEAT Leon for four visits to the selling garage under warranty over about 9 months and I went on her last visit where it was found to be the common problem of charger cooler leak (after they'd claimed to replace the expansion cap and said car was fine, then claimed to have replaced the expansion tank and everything was fine, then something else do and everything was fine).  She had the car serviced last week and the guy that done it said the charger cooler hadn't been fitted correctly and there was a small leak!

 

@rum4mo sure you know to check previous work done before you start, even if it was you that done the work.
