hi guys

 

bit of an update:

 

i have cleared the codes twice now and each time the misfire code pops up so will have to change it to cylinder 1 and see if the codes pops up for cylinder 1.

 

the air con code has gone now, i did what xman said, get rid of the dust in the vent by the climate button and the code has stopped coming up, just the radio thats it.

 

while i got the obdeleven connected to my phone, i had a look around on the obdeleven and it says that i have a newer software to download?

 

 

No, leave the ECU firmware alone, you'd have to go ask a dealer to change it so you don't need to worry about it.

Probably nothing but it's important to remember that a PCM is NOT like a smartphone, the firmware it comes with was designed to last the life of the car.

ok thank you again  

 

will be going out shortly to get a coil pack, will update later.

So did you swap coils over between 1 and 3 and witness the misfire move across?

 

If you haven't, then maybe yet too early to be buying that new coil.

 

Have you changed the vacuum pipe? Just to point out that the pipe draws the vacuum from the inlet manifold in the vicinity of cylinder 3 so if theres a bad leak, that cylinders mixture will be affected most.

no not changed the pipe yet, the pipe has been like that since i got the car. i have just took pictures of the serial number for the pipe and will order it soon. i have just swapped the coil pack between 1 and 3, cleared all codes then just drove down to shop and back, only a few minutes drive. its very strange because the only code showing now is the gateway: radio.

 

postimage website is down so cant uplaod the screenshot.

You can upload a set amount of images here too using the little "add files" for mobile or the bit at the bottom of the WYSIWYG chat box that you'll be typing a reply in, if you're on your computer. If you've used up your space, then purchasing FREEDOMlite or FREEDOM is a good choice since it'll give you more storage for images. It doesn't cost much and contributes towards the running of the site and comes with added bonuses.

another update:

 

took the car out for a longer drive and these codes popped up:

 

cyl.3 misfire detected fault code: P0303

 

central electrics: radio fault code: 01304

 

 

so yeah, it looks like i need to replace the servo pipe then it will be fixed.

Let's hope so.

thing is though, it still drives fine, idles fine and no check/engine light.

Can you repair the servo pipe better to temporarily ensure that it's not leaking at the cracked sections? 

Self-amalgamating tape reinforced by a few cable ties is probably better than anything else bodge-wise, and what I've done on my Polo recently as a stop-gap until I replace it. 

 

I keep meaning to see if the one on my other Polo is the same and in a better state, as that car's off the road.

you must have already seen my work, i have put more tape on with cable ties  

 

from what i can see and feel, its only one side of the pipe that is split.

 

 

that round thing at the back where the pipe connects to, that is the only split that i can see and feel.

 

i did follow the rest of the pipe and tried to feel for any split but couldnt find anything.

Don't suppose you own a compression tester or know anyone that does?

i did have one but sold it as i didnt use it.

 

i am going  to garage in about 10 minutes, i will asked them to do a compression test.

 

do you think that has something to do with it?

One reason for misfires on the HTPs, though mostly the single-cam 6-valve ones, is exhaust valve damage.

This might show up as a lower compression value on that cylinder compared with the other two.

just got back form garage, the guy plugged it to his computer and it was showing misfire on his computer too. he put one of the old spark plug i had in boot and changed it on the cyl 3 and the misfire had gone. it was a faulty spark plug so i am happy now, just need to order another one now  

 

want to say thank you for your help and everyone else who helped too   

Thing is you know that brake assistance (vacuum) disappears immediately when the engine is switched off. That means there is a vacuum pipe leak or the non return valve is not working or both.

 

The splits usually hide round the back out of view.

 

As I said earlier I used amalgamating tape, supertight and overwrapped the connectors and non return valve. It helped a little, but still didn't have vacuum for more than a couple of seconds after switch off. When I inspected the removed pipe and removed the tape, the joints just fell apart they were that loose. And I could blow both ways through the non return valve, though the blocking direction was harder. Obviously contaminated or worn/damaged diaphragm internally. So no amount of bodging would have fixed it.

i will be replacing the servo pipe as soon as i can find some, i am struggling at the moment. i have checked my serial number and it is same as yours:

I think its only available from dealers or TPS (trade only), ask your mechanic to check.

ok will give that a go, many thanks again for your help  

ok guys, 

 

another update, it is still misfiring on cyl 3. i am going to try replace the vacuum pipe now, is it ok to order from abroad on ebay?

 

https://www.ebay.co.uk/itm/254731639828

 

also i cant order it till thursday as that is when i get paid, i still have to wait 2 more weeks if i ordered from abroad. its the only place i can order from, cant find any in the uk. is it ok to drive it for another 2 weeks if i drive slowly/steadily?

For heaven's sake why pay that much?

 

The parts compatibility selector says it doesn't fit a BZG engine,

 

The drawing is not right, there is no clip on the original and it looks very different at the manifold end.

 

Phone your local TPS centre on 01422 205051 (Halifax) and ask for price and availability should be about £40

I'd be tempted to prioritise the compression test, in view of the coilpack swapping result, but if you do want a new servo pipe, this seems to be a cheaper source: Volkswagen / Seat / Skoda Vacuum Pipe With<Br>Non-Return Valve 6Q2612041AL - LLLParts

 

PR-T70 is the 3-cylinder 12-valve engine.

i just thought it would arrive quicker if i ordered from ebay than it would from the dealership. i just went by the model number on the ebay one.

 

i forgot to update my profile, i live in cornwall now and the garage i used told me it would be better to order the part elsewhere as they dont get discount price and that  it would have cost couple of hundred pounds.

 

also the price for the ebay one is same as the dealership. when i goggled the exchange rate for the dealership it came to 56 pound delivered.

thank you for that

 

when i did the exchange rate on google, that came to 35 pound delivered, so saving over 20 pound compare to the dealership and ebay.

 

i will order this one on thursday.
