Should I try taking it round the block with the Intercooler pipe disconnected? (I disconnected it from just before the MAP if you were wondering) |

Putting petrol in it wouldn't give these symptoms would it? Just a random thought. No I haven't put petrol in it. Just that my mum put a tenner in the other day just to top it up. Can't imagine she'd put petrol in but just wanna cover all my bases xD |

Depending on the amount put in and diesel in the tank, petrol would either not hurt, make it cough and splutter, or just not run at all.

It's one of two things: it's either the vacuum hose going from the air intake to the boost solenoid, or the little nozzle for said hose on the air intake, as it does move about a bit and has probably lost it's seal over time. I initially took that hose off and blocked it's nozzle on the boost solenoid, as i recall reading yesterday that it was a vacuum release pipe. So i thought, "maybe that's got a leak, let's just try blocking it" and low and behold, it worked! Albeit not 100%, as i only blocked it with a latex glove and a zip tie xD. But it did restore most of the power, but it restored the necessary vacuum for the actuator and shut off valve to work. I tried it both with and without that pipe on, and it made no difference, so i assumed that there must be a leak in the hose, for it work no better with it, than without it. We (me and my uncle) found a hairline split in the hose, so we sealed it up with self amalgamating tape and whacked it back on. Sealed for about a minute or so, then went back to gutless, only being slightly more powerful than before, without any noticeable smoke. So that brought me to the conclusion that either the hose has expanded/split somewhere else, causing it to not seal properly, or that the nozzle on the air intake was leaking, or the end had worn down (the tip of the nozzle did look quite worn i must admit). So i either need a new vacuum hose, or air intake pipe. Preferably both. Can't imagine they're gonna be expensive. To eBay!! |

Sounds like progress!
As it happened to you rather out of the blue, I guess that was the day it broke free... Either fatigue or from cleaning, maybe both... It probably managed with the split in the vac pipe until the spout broke and tipped the balance. New pipe and repair or replace that bit you may be laughing! As a temp fix you could JB Weld it. |

Easy way to get brand new parts. Get them delivered straight to work, pay my boss for them, and Bob's your uncle! It helps working at a dealership xD |

Sounds promising!
Like I said, Renault make em all up the same, some go in their cars, some go on crates to other manuf's, even most of the ancillaries bundled with em to bolt on somewhere the manuf. sees fit. 👍 |
