My vrs turbo which pipe

[Burkevrs]

Hi I started my mk1 octavia vrs yesterday went from 1St going into 2nd had big pop thought I blown a tyre I know a pipe blown off but need idea which my mk1 got big intercooler on it and remapped I'm think pipe from the turbo someone help me so I can buy before taking things off to look

There are 2 possible culprits :-

1/ Get the car up on ramps with bonnet up look at rear of engine from front of car, note the large stainless charge pipe that runs from right (turbo)

across to left then dives down vertically). Now get under car and find that pipe, the end of it is covered by a heat resistant pop together cover, unclip that and you can see the crap spring clip that secures both pipe ends together, see if you can pull the rubber hose down, if you can it needs re-assembling to the stainless charge pipe, also make sure the spring clip locates on the 2 barbes (part of metal end on rubber hose).

2/Also check the short straight bit of rubber pipe that links the pancake pipe (flattened dull stainless) to the intercooler. This can be better seen if you jack up the front offside and remove the roadwheel, check the 2 hose clips there, sometimes this hose can become detatched at either end.

NB: I would check all the hose clips and just tweak them up a bit more

This is quite difficult to diagnose remotely as there can be one thing or a number of minor problems all conspiring together.

To get to the root problem/s can i suggest you find a fellow member nearby to run a diagnostic scan using vag-com,then we can

look at the error codes if any.

Also what year is the car, list all the mods its had done and what its mileage is, otherwise, to be fair to everyone it will be very much hit or miss

and going down a route of "try this / try that etc".

It's 02 vrs had walley front mounted intercooler remap miltek exhaust system sports cat got cone air filter boost pipes are sillcone forge its at 210 ish bhp mileage 129395 I've recently done track rod ends and both wishbones it's hit and miss took my lad back to his mum's on the way there was boosting 6 psi switch off when I got back in it to go home it was back to normal self boosting give it a trashed back home I'll get on the ramps have a deep inspection get to the bottom off it I live near wrexham in rhos any members by me with vagcom will grateful

Forge boost pipes are very good quality, plus the front mount welly i/c has had good reviews.

It will be interesting to see what error codes surface.

Try this link for brisky people with diagnostics :-

Checked my pipes none popped out arrghhh hope it's not n75 or maf sensor that's all I can think of the coils should be ok not running rough

"went from 1St going into 2nd had big pop thought I blown a tyre", are you sure this wasnt a exhaust backfire?.

Has the car lost power since the "pop"?.

Without having a stationary diagnostic scan and/or some real time readings (you driving, laptop plugged into diagnostic port and passenger capturing boost/rpm numbers), i'm afraid its pretty hit and miss. How about contacting the people who did the remap?.

I guess it all depends on how deep pockets you have, yes, it could be the N75 mind you ive never heard of one going pop, or a diverter valve diaphram splitting (if you are using a std one and not a forge aluminium one or similar). The ally ones have a nice sliding piston with o rings or maybe a seal in the turbo has given up the ghost.

GET A DIAGNOSTIC SCAN DONE !!!!!

Got someone with vagcom next week happy days hopefully get to the bottom of it I'm getting new custom remap in 3 weeks

Good,

If you have a load of error codes logged, make a note of the numbers, clear the codes, go for a short run and do another scan.

Sometimes if a particular code is not resolved or cleared it can trigger other error codes. So the important source error can be hidden

in amongst its "daughter" errors.

If it hasnt already been done to your car I would suggest looking at fitting a Neuspeed 28mm rear anti roll bar (or similar) to stiffen the back end up, replace shocks coils all round and front strut braces (upper and lower from audi TT) also a Golf R32 front Anti roll bar ( the vrs has a std dia 19 mm, R32 is dia 23mm). Also look at supension bushes Superpro help to stiffen things up. Last but not least improve the braking ability (plenty of mods on here, just do a search).

Its all very well being the fastest away from the lights, but if you come to a sharp bend and end up wallowing into the bushes, game over.
