    On Sunday I was on my way to Southend from Bromley Kent and whilst tagging with a Jag and a A5 TDi up my arse my car seemed to drop to 3 cylinder so I pulled over just as the engine light started flash at me.

    First I thought it was the new spark plugs so after rerouting to Basildon Halfords I picked a spark plug remover and popped them out one by one and swapped in the old one back in only to find the problem was still there. Scratching my head I cam down to the conclusion I had lost a coil pack so I limp her back home and bought a new one yesterday and after working out which cylinder was playing up swapped out the coil pack.

    Well it not the coil pack as all four are firing so I'm left with only one thing and that is the timing belt I did the weekend before when replacing the water pump as slipped a tooth and I now have a busted piston(s) (Dam I don't need this right now).


    If any of you can think of something else it might be I'm all ears but my gut instincts say it’s at least one cylinder as bitten the dust.

    Morning
    A flashing engine light is a missfire as I'm sure you know, run a scan and see what codes you get.
    It's human nature to blame yourself for some recent work you've done, I've lost count of the number of times I've done it and it's turned out to be something completely different.
    Hope it's not expensive.

    Hope is all I have right now.

    I will have to work on getting my Laptop and ebay lead to link up so I can pull of the codes.

    Is there anything physical to make you suspect the belt has skipped? I don't think it would just skip unless something caused it to, like a pulley failing or power sterring belt popping? Having said that I'm not familiar with the 1.8T engine.

    Can you see in under the timing cover at all to see if it all looks normal?

    What a b*st*rd :(

    Just got off the phone to my mate who owns VW Enterprise and he said to bring it down.

    He advised that it would be very unlikely to take out an engine if the TB slip a tooth but it would cause it to run badly he also advised that the fact that none of the spark plugs are coverd in oil or the engine is not smoking that things may not be as bad as I think so roll on 3pm so that I can get out of here and get my car down to his work shop.

    UPDATE: Car broke down on the way to my mates work shop so had to get a tow after I found the CAT was glowing which first led me to think the CAT had collapsed; but this turned out not to be the case.

    It was 7:30pm before I got to his workshop after setting out at 3:00pm then trying to do a few things my self and waiting 2.5 hrs for the tow truck.

    Anyways he did a compression test on number 2 which is clearly where the issue is and all was fine he checked plugs and they look good so it's starting to look like an electrical fault on the coil plug lead which he will look at today after giving it a scan.

    Picked the car at 9:30 pm and it all nearly done.

    Turned out to be the injector after all, when I dropped the car off the first thing he did was pop the fuel rail out and turn the car over to see if the injectors would work and they did all four. It turns out that it would work for the first 10 seconds then shut down but after swapping them over after a lot of head scratching he worked it out.

    The only problem now is that the car will only boost to 7psi which we both think is the CAT blocking the exhaust due to it over heating and collapsing, so I will be unbolting the CAT and down pipe later and bolting in my new HFC and Milltek down pipe.

    Just read this thread..

    Glad you managed to sort it out without too much trouble mate.

    Are you running the 'Outlaw' turbo now? If so have you had it mapped yet?

    Sorry just read your 'to be fitted' list so I pressume you're probably waiting until it's all together for your map.

    Yep looks like game back on and yes the Outlaw K04 is on which pulled very strong on stock map I'm pleased to say.

    Still not mapped the car up as I have a few thing to fit still but I was talking to my mate whos a GIAC dealer who recons I could get one of GIAC's K04 maps then pop down to Southhampton and get it fined tuned for the Outlaw K04.

    Have any of you guys got any other option for mapping?

    Easy for you with your flashy ECU lol. Yeah I'd probably go with the GIAC map and have it tweaked too if I had the same setup.

    I've been in contact with Unitronics..

    http://www.unitronic.ca/

    ..as I'm doing a T28 hybrid conversion and they have off of the shelf maps to suit. I'm having to swap ECU and loom though as mine is the very old type. Not got a definite plan yet as mine's UK spec there may be a few issues.

    Sent emails to Jabba too but had no replies yet. I'm going to try and ring them this week though as they originally recommended the ECU and loom conversion for the T28 as they say they'll be able to custom tune.

    time for uprated injectors? if you're swapping them over, might as well ;)

    should be pulling about 320-350bhp once all of that is done and mapped properly?!?

    I'm hopping for a bit more than that based on the fact a stock K04-15 will do around 240-250bhp with the right hardware and map

    More than 350HP?.. can the K04 Outlaw flow that much air?

    Oh yeah.. think you might be right lol.

    I'm going to go for 415cc injectors and TT 225 MAF housing.

    I would like to see close to 300HP but obviously don't want to push the standard internals too far.. Good reason to rebuild if they do let go though I guess.

    I thought that with uprated turbo and injectors and standard internals, the 1.8T's are good for around 300bhp and anythign up to 340bhp with a few extra tweaks... but beyond that you're on your own...

    Yeah sounds about right but it's definitely getting close to the limit.

    Agreed 1.8T's usually hit the old diminishing returns rule around 250-320bhp... depending where your pain threshold for throwing lots of money in for a few bhp extra....

    I've seen dyno runs of >430bhp on those 1.8T's, but those had a "few" extra mods... check out the awesomegti video section with the Golf RR days: it was a Mk2 that had the 430bhp 20V engine!

    Boosting 7psi!!! - Mine was the same mate, CAT was fcuked and it really struggled. Once you get the HFC and downpipe on then game on...im sure you know that anyway!

    Im interested to see what BHP at the wheels you get with all these tweeks you doing. One minute im all up for turbo upgrade then next im thinking naah!! - until I go across to the Ziners and it gets me all going again...:eyebrows:

    If you could find a modified car friendly MOT station then it wouldn't be a problem :think:

    Well the HFC (High Flow CAT) is on as is the Milltek down pipe and what a bitch that was to fit by the road side.

    Things look good with 10psi back but I'm not convinced some of the old cat did not make its way down to the Milltek resonator so I may have to take them off.

    In all it pulls strongly again and the system sound a little more throaty with the two new additions and the turbo starts pulling from 2k rpm. The CAT died due to me driving around 40+ miles on 3 cylinders which I would now not recommend due to the obvious but now she's all up and running sweet again.

    Mark, I may go GIAC if you guys don't come up with any other good options due to the fact GIAC already have a aggressive K04 map and this could be used until I get them to tweak it on the rollers for the Outlaws greater power.

    After a week, how is she running on the Outlaw mate?.

    I put mine on a std ECU the other day and she spiked 12psi, still had that nice spool sound too.

    Jabba seem to be the recomended tuner for us ATM £500 for a proper custom tune for Lee's T28

    She seems fine but I have a feeling some of the original CAT content is in one of my Resonators so Friday evening I will climb under the car and split the exhaust (one of the advantages of having a Milltek I think).

    Car is boosting to around 9-10psi which is fine but when I first fitted the K04 Outlaw it would spike around 13.5psi so it may be partially blocked at the res.
