Hello everyone, here's my story-
Megane 1.9dCi started to lose power when accelerating hard and the Diesel Heater light came on. I removed the
valve and cleaned it- it was filthy and the ports were almost completely blocked. After refitting and testing the car was still the same. I removed the
again and cleaned as much as possible of the sludge from the inlet manifold using the threaded bar with a washer technique (thanks whoever posted that).
Then I bought a can of 10k Boost Power Restorer. I was a bit sceptical- the way it's used is by spraying directly into the intake, after the mass flow meter with the engine running- one minute spraying followed by 10 minutes idling, repeat until can empty, then give it a good rev and drive for 10 mins.
IT WORKED BRILLIANTLY!
The car is back to full power and the Diesel Heater Light never comes on.
After using the spray (£19.99 from Halfords) and when I revved it there was a huge cloud of blue/grey smoke, after this cleared I drove it for 15 mins and was amazed- it felt like a new car again.
I hope this helps other people, I thought my
was packing up (megabucks) so a £20 can was worth a try- I'm so glad I did.
