driving today and everything was fine till my rear passenger side tyre mounted the kerb, i now have a boost leak, gauge isnt getting above 1.5 psi, im assuming a hose has came loose somewr, car drives fine but every now n again it will judder etc, any1 any pointers in wr to start here :)
-
checked all hoses visually and all seems fine, noticed car seems ruff on idle now as well with rev fluctuations, if the car has went into limp home mode, do i need to reset the ecu to get back out or is it automatic
-
i belive that you need a code reader to erase any codes to get it out of limp mode?
ide turn the car on and try listne out for any boost leaks too (might be hard over engine noise)

i see, that wouldnt explain the bad idling tho eh, have tried to listen and feel for any leaks, cant find any
-
bad idling will be a leak somewhere, pulling in un-metered air

could just be a tiny leak.
perfect time to upgrade hoses :wink:

iv upgraded a few but checked all those n they seem fine :(

I may be wrong but I think limp mode goes off when you turn the car off. Obviously if whatever caused it happens again once you start her up again then it will go back into limp mode until switched off again. I was switching the car off and starting it up again whilst moving when I had the problem with mine.

Did you hit the kerb hard.? Does you car sound like its running on 3 cylinders. You got agu with a cai, you know what i think it is. :wink: ign amp.

didnt think it was too hard tbh,on start up its ruff then idles for a while and then goes ruff again, , its actually cutting out now, have checked the ignition amplifier, seems ok, but my experience with them is limited lol

meant to add, been looking for signs off oil smears etc fr signs of leakage and have noticed a small amount of oil has built up at the bottom of the TIP just before it attaches to the turbo, could this be a leak

i think you will only see a oily boost pipe on the boost side not before the turbo, i could be wrong. Thats a good way of finding boost leaks.
-
You got any fault codes.
-
not got diagnostics, might go to halfords n get a cheap 1, bought an ebay version of vag com but its not worth a dam :(
-
You want a cheap plugin one off ebay.

-
another note, when installing my new tip, i had to mess about with the bottom outlet on the tip, (the bit that should have a nipple on it for a hose), i fabricated a makeshift nipple, how important is that hose, i believe its to do with the PCV or something

thanks m8 been looking at that actually, was wanting to get str8 in about it tho without waiting lol

just seen this, says its updateable, dont think they bring out new fault codes do they, although user interface looks neat :)
-
looking into making a boost leak tester :)
-
bet its not a boost leak. If it was fine then running sh!t. Go for common faults ie: ign amp , maf (bet its not that). Agu are mint , tighten all boost pipes , get fault code reader. But if you think its in limp mode , got to say its your ign amp. Its common if you removed it .Trust me. But there £60. :sad:

beginning to think this myself, ordered that code reader off ebay so will wait for that, maybe even try n wangle a free check from somewr local, when you say removed it, iv just placed it out the way, i was curious about this when i took it off the airbox and asked on here, u reckon it cud be knacked, is there a way to test it
-
cud it be a fuel related problem perhaps, maybe the bump has upset the filter or that
-
common faults suck. First place to look. Me and your + load of peoples fault for removing the amp from the airbox. One comment told me what it was ( it sounds like a retarded subaru) :grin: your not wrong there. £60 later it was fixed. But still run a cold air filter, but put pc heat paste on amp were the alloy heat sink sit .VW put jack sh!t behind it. :shocked:
-
iv been in cars that went up a kerb full speed . :evil: and a golf .Big dent in wheel and tyre has a lump poping out of it. The cars were fine after new wheel and tyre. God iv been in some bad cars with a bad driver. :evil:
-
cheers m8, just that ive replaced the tip and some hoses which is leading me to believe it was a boost leak, well that and the fact im only getting 1.5 max psi lol

check if theres anyone on here near you with a fault code reader. Or if you can try there ign amp. :wink:

another note, i changed the spark plugs the other month there, they were 0.1mm of a gap difference, been runnin fine for bout a month tho,
-

I just changed spark plug, i was does about to put old ones in then thought ign amp. You need to check your tip first. If its all tight get a new amp. :wink:

what plugs you got.?????
-
tip seems fine and all clips etc are tight, only dodgy one is the 1 near the turbo inlet which links to the pvc system, however i think this is sound, will a faulty amp bring up a fault code
cant remember what plugs, bosch ones, looked them up in there manual, but found out when i got home that they wr 0.1 mm of a difference, as i said its been fine, might put the old ones bk in to rule them out
-
A months good .Had pulse plugs fail in 6 miles ( 2 sets). Ngks best (PFR6Q)but its wont be the cars fault. UNLESS there nology silver they jurk on boost (stage 1 map). :sad: But never failed. Cant beat ngk. :smiley: AGUS LOVE ngk OR Bosch 4S (but never used them) ( i class them as cheap). :lipsrsealed: Years back max power showed the gains of plugs bosch 4 , they sucked but do there job well.
-
My amp had no code. :wink:
-
il check the plugs n that whilst i wait on the code reader or find sumwr to test it for me

thanks for the offer m8, wr bouts are u like
-
just done a MAF test, unplugged it whilst running, didnt appear to do anything, does that mean anything
-
does the car try to stall when you plug it back in?

2 mins from erskine bridge :smiley:

didnt have time to do anything tonight but yes it started going erratic when i plugged it bk in, and nearly stalled. when i initially start the car, the revs will hold at 1250 for a few seconds then drop to 1000 and jump up n down a few times before goin dteady again, this seems like a commom cycle its doing

thats miles away m8 lol, shud have a diagnostics reader mon/tuesday hopefully, busy as fk til then anyway
-
diagnostic tool will hopefully be here today, will let use know what i find :)
-
scanner arrived :), have fault code 00532(P1746) - Transmission Control Unit Relay Malfunction.
any1 had this before, im assuming its my problem lol
-
forget that, that was because i disconnected the battery, have cleared all codes and ran engine again, still jumpy although i have a 16486 (p0102) Mass or volume air circuit low input, im assuming i just need a new MAF

Have you run it disconnected? clear it and if it returns yeah i would say the MAF is dead.

have disconnected it as said previously, im sure it ran better with it unplugged, will it be better to take it a drive with the maf unplugged

I would clear the codes connect the MAF drive it if the code appears get a new MAF :smiley:

cheers bud, just ordered a new MAF anyway, TMS - £51, that seem ok
-
took car for a spin with the maf unplugged, drove a hell of a lot better, plugged the maf bk in n it was sh!t so i think iv got it :)
-
was the MAF sensor guys, swapped it out for a new 1, its spot on now thank god, thanks for all your input guys its appreciated, would have been swappin parts left right n centre til i got it, very handy tool that code reader, very well worth investing in 1

Good stuff :cool:
Do me a favour tell all the people that just post about faults with out having it scanned :grin:
-
will do lol, quick 1, would i see better MPG with it bein a new maf or what :)
-
a faulty maf can destroy your fuel economy
