Boost Leak

[Azman]

Hi Guys,


Right been off the circuit for a whil due to health probs (hopefully all sorted now after a nice trip to hospital), so need to sort a few bits out now. Right then the car seems to have an intermitant boost problem and cuts quite strongly if boost is maintaned over 0.5 bar for about 5 secs.

Is it a boost leak and if so where could it be coming from?? I have done the mark H mod already to take that out of the equation but still happening and seems to get worse. Even at 0.5 bar the car does not move the way it should. Thoughts on where to look?

Hopefully going to get it Vagcom'd later today to see what codes are coming up.

Only way to find these is to pressurise the whole system. Best get the vacuum lines replaced and sealed with small cable ties. Good luck, these boost leaks are one big PITA!

Going to order a whole pile of slicone vaccum line to replace the whole lot as a first port of call in blue me thinks isn't there small clip things we can get instead of cable ties or are they just easier??

Oooo also forgot to mention after driving for a while takes a little while (30 secs or so) to find idle at 800rpm again rests at 1200 first then gradually sinks down????

Az - you must have an air leak... Look at the LOAD blocks on VAGCOM during a warm idle - they need to be in range - otherwise the engine is getting unmetered air from a split hose somewhere.

PS - I need to get a run over to your neck of the world for the small matter of a rear diff !!! I'll send you a PM with some possible dates... Sorry to hear you have been ill - hadn't seen you round for a while.

cable ties are best

Coolio Paul the diff is in the back of the avant so I can drive it closer to you if required. Are you coming over for ADI as it could be arranged for that weekend?

I dunno yet if I'll be there for ADI - I would really like to be... Just not sure if I can do it yet - and if I do it might be cheaper to fly into Bristol and cadge a lift. Will let you know ASAP.
